Item Dientamoeba fragilis, a neglected cause of diarrhea, successfully treated with secnidazole(Blackwell Publishing Ltd., 2003) Girginkardeşler N.; Coşkun Ş.; Cüneyt Balcioǧlu I.; Ertan P.; Ok Ü.Z.Objective. To evaluate the pathogenicity of Dientamoeba fragilis by comparing it with Giardia lamblia and to investigate the effect of a single dose of secnidazole in dientamoebiasis. Methods. Stool samples of 400 patients, admitted to the Department of Parasitology, Celal Bayar University, were examined by direct wet mount, formalin-ethyl acetate concentration and trichrome staining methods on three consecutive days. All cases positive for D. fragilis were treated with a single dose of secnidazole, 30 mg/kg for children, and 2 g for adults. On the seventh and fourteenth days, at the end of the treatment, stool samples were examined by the same methods, and clinical symptoms were again evaluated. Results. D. fragilis and G. lamblia were detected in 35 (8.8%) and 34 (8.5%) cases, respectively. The most frequent symptoms were found to be abdominal pain and diarrhea in both infections. D. fragilis was eradicated in 34 (97.1%) patients with a single dose of secnidazole, but a second dose was necessary in one patient. Clinical symptoms disappeared in 27 (77.1%) and decreased in eight (22.9%) cases, after eradication. Conclusions. These data suggested that D. fragilis is as prevalent and pathogenic as G. lamblia, and secnidazole seems to be highly effective in achieving parasitologic and clinical cure. To our knowledge, this is the first report of secnidazole being used in the treatment of dientamoebiasis.Item A discrepancy between cystic echinococcosis confirmed by ultrasound and seropositivity in Turkish children(2005) Özkol M.; Kilimcioǧlu A.A.; Girginkardeşler N.; Balcioǧlu I.C.; Şakru N.; Korkmaz M.; Ok Ü.Z.In three randomly selected villages of Manisa, Turkey, 630 primary school children were examined for cystic echinococcosis (CE) by a portable ultrasound scanner (US) and chest microfilm. Sera samples of 483 (76.7%) children were tested for anti-E. granulosus antibodies by ELISA and indirect hemagglutination (IHA) tests. Hepatic CE were detected in two cases (0.3%) by US, while 43 (8.9%) and 49 (10.1%) cases were found to be positive for CE by ELISA and IHA, respectively. The high seropositivity levels could have been attributed to extra-abdominal or abortive Echinococcus infections, but probably most of them were false-positives. Due to the discrepancy in results, US should be selected as the primary test in field studies and serologic tests should be performed in all cases with suspected lesions. We could not find any reported community based study on CE in Turkey, in which US was applied; but our results suggest that extensive epidemiological studies are required. © 2004 Elsevier B.V.

Six hundred and thirty children from three villages, examined by a portable ultrasound scanner, chest microfilm and serological methods (ELISA, indirect hemagglutination) in our previous study, were designated as Study Group 1; and 575 children, from two adjacent villages, examined by ultrasonography alone in the present study, were designated as Study Group 2. In Study Group 1, hepatic cystic echinococcosis was detected in two cases (0.3%) by ultrasonography, while 43 (8.9%) and 49 (10.1%) cases were found to be positive for cystic echinococcosis by ELISA and indirect hemagglutination, respectively. Three of 575 children (0.5%) were diagnosed with cystic echinococcosis (two hepatic and one renal involvement) by ultrasonography alone in Study Group 2; and lung lesions were later detected in both cases with liver involvement by chest radiography. Our results suggested that serological tests may be beneficial in suspected cases for confirmation and differential diagnosis, but have some drawbacks, such as discrepancy in results and high false seropositivity rates. Chest microfilm is not easy in field studies and exposure to X-ray is undesirable. As a reliable, simple, inexpensive and rapid technique, ultrasonography alone is recommended to be used in community-based screening surveys for cystic echinococcosis with confirmatory tests for suspected cases found during the screening program. © 2006 Elsevier Ireland Ltd.

Intestinal parasitic infections affect child health and development and slow down growth, while reducing adults' productivity and work capacity. The aim of the present study was to determine and compare the incidences of intestinal parasitic infections and the socio-economic status of two near primary school children in Manisa, a western city of Turkey. Methods. A total of 352 children were involved a questionnaire study from a private school (Ülkem Primary School - ÜPS, 116 children) and a community-based school (Şehzadeler Primary School - ŞPS, 236 children). Of these, stool samples could be obtained from a total of 294 students; 97 (83.6%) from ÜPS, and 197 (83.5%) from ŞPS. The wet mount preparations of the stool samples were examined; samples were also fixed in polyvinyl alcohol and examined with modified formalin ethyl acetate sedimentation and trichrome staining techniques. Data were analyzed using SPSS for Windows version 10.0. The chi-squared test was used for the analytic assessment. Results. The percentages of the students found to be infected with intestinal parasites, were 78 (39.6%) and 13 (13.4%) in ŞPS and ÜPS, respectively. Totally 91 (31.0%) of the students from both schools were found to be infected with at least one intestinal parasite. Giardia lamblia was found to be the most common pathogenic intestinal parasite and Blastocystis hominis was prevalent independently from the hygienic conditions. The factors which significantly (p < 0.05) increase the incidence of intestinal parasites were uneducated and unemployed mother, lower social status of father, living in crowded houses with insufficient indoor spaces, using the tap water as drinking water, and living at shanty areas. Conclusion. Intestinal parasitic infections in school children were found to be a public health problem that increased due to lower socio-economic conditions. We conclude that organization of education seminars including the topics such as prevention of the infectious diseases, improving general hygienic conditions, and application of supportive programs for the parents may be suggested not only to reduce intestinal parasitic infections, but also to elevate the socio-cultural levels. © 2007 Östan et al; licensee BioMed Central Ltd.Item A province-based study using sampling method to investigate the prevalence of cystic echinococcosis among primary school children in Manisa, Turkey(2007) Ok U.Z.; Özkol M.; Kilimcioǧlu A.A.; Dinç G.; Bayindir P.; Östan I.; Pabuşçu Y.; Özcan C.; Korkmaz M.; Coşkun S.; Yüksel H.; Girginkardeşler N.A province-based field study using a portable ultrasound scanner (US) was performed for the first time using sampling method to investigate the prevalence of cystic echinococcosis (CE) in primary school children in Manisa, Turkey. A total of 6093 children from 37 primary schools was selected as the representative sample of the total number of 166,766 primary school children, and examined by the US. Prevalence was found to be 0.15%, as nine children were diagnosed with CE, seven new and two previously operated. A questionnaire applied to the children revealed no significant relationship between the risk factors and the infection (P > 0.05). In conclusion, it would be advisable to repeat the study at the same schools in eight years' time, in order to evaluate the efficacy of the control programs, since nearly all students involved in this study will have graduated by then. Besides, it is recommended to choose a sampling group to find the prevalence of an infection in a defined region. © 2007 Elsevier B.V.

Metronidazole is a well-known and commonly used anti-protozoal agent, but another 5-nitroimidazole derivative, ornidazole, may be preferable, where available, because of its longer half-life and fewer side-effects. This study compared the efficacies of metronidazole and ornidazole in a group of 112 patients with dientamoebiasis. Patients were randomised into two treatment groups: group.1 (n = 56) received metronidazole for 5 days, 20 mg/kg/day for children and 1.5 g/day for adults, in three oral doses, while group 2 (n = 56) received a single oral dose of ornidazole, 30 mg/kg for children and 2g for adults. Stool samples were examined on the seventh and 14th days after treatment, and clinical symptoms were recorded to evaluate the efficacy of treatment. A statistically significant difference was recorded between the efficacies of ornidazole and metronidazole, both parasitologically (92.9% vs. 69.6%, p 0.001) and clinically (96.4% vs. 76.8%, p 0.001). Patients in the metronidazole group reported more side-effects than patients in the ornidazole group, none of whom required termination of treatment. These results suggest that single-dose ornidazole may be an important alternative agent for the treatment of dientamoebiasis. © 2008 European Society of Clinical Microbiology and Infectious Diseases.Item Transmission of Dientamoeba fragilis: Evaluation of the role of Enterobius vermicularis(2008) Girginkardeşler N.; Kurt Ö.; Kilimcioǧlu A.A.; Ok Ü.Z.The role of Enterobius vermicularis in the transmission of Dientamoeba fragilis has been evaluated in two groups of patients admitted to the Parasitology Laboratory of Celal Bayar University: one group with E. vermicularis infection (n = 187, Pinworm Group), and the other with D. fragilis infection (n = 126, Dientamoeba Group). The presence of the other parasite, pinworm or Dientamoeba, was investigated with the microscopic examination of cellophane tape and stool samples for three consecutive days. In the Pinworm Group, 9.6% of the patients were found to be coinfected with D. fragilis, while 25.4% of the patients in the Dientamoeba Group were found to be coinfected with pinworms. The coincidence rates of D. fragilis and E. vermicularis, higher than the prevalence of each parasite in similar populations, suggest a common relation between these two parasites, possibly in entering the human body. E. vermicularis infection was found to be significantly more common in younger children (p < 0.001), indicating that younger children may also be at higher risk for D. fragilis infection. These findings also raise the question of whether the unrelated symptoms of the pinworm infected patients such as abdominal pain and diarrhea may actually be due to overlooked Dientamoeba infections. © 2007 Elsevier Ireland Ltd.

Dimeticone 4% lotion was shown to be an effective treatment for head louse infestation in two randomised controlled trials in England. It is not affected by insecticide resistance but efficacy obtained (70-75%) was lower than expected. This study was designed to evaluate efficacy of dimeticone 4% lotion in a geographically, socially, and culturally different setting, in rural Turkey and, in order to achieve blinding, it was compared with a potential alternative formulation. Methods. Children from two village schools were screened for head lice by detection combing. All infested students and family members could participate, giving access to treatment for the whole community. Two investigator applied treatments were given 7 days apart. Outcome was assessed by detection combing three times between treatments and twice the week following second treatment. Results. In the intention to treat group 35/36 treated using dimeticone 4% had no lice after the second treatment but there were two protocol violators giving 91.7% treatment success. The alternative product gave 30/36 (83.3%) treatment success, a difference of 8.4% (95% CI -9.8% to 26.2%). The cure rates per-protocol were 33/34 (97.1%) and 30/35 (85.7%) respectively. We were unable to find any newly emerged louse nymphs on 77.8% of dimeticone 4% treated participants or on 66.7% of those treated with the alternative formulation. No adverse events were identified. Conclusion. Our results confirm the efficacy of dimeticone 4% lotion against lice and eggs and we found no detectable difference between this product and dimeticone 4% lotion with nerolidol 2% added. We believe that the high cure rate was related to the lower intensity of infestation in Turkey, together with the level of community engagement, compared with previous studies in the UK.

All stool samples were examined with wet mounts, formalin ethyl acetate concentration and trichrome staining methods. In addition, cellophane tape preparations from 5952 patients were evaluated. Intestinal parasites were detected in 2337 (13.12%) of 17.711 patients who were admitted during a five year period. The highest parasite infected individual ratio (16.69%) was found in 2008. The most frequently identified intestinal parasites were Blastocystis spp. 1353 (7.64%) and Giardia intestinalis 348 (1.96%) in stool samples, with Enterobius vermicularis 253 (4.25%) in cellophane tape preparations. Two or more parasites were detected in 158 (6.76%) of the positive cases. The mean age of persons identified as having a parasite was 21.9. Parasite incidence was 10.7% in females, and 13.6% in males (p < 0.001). The highest ratio was 23.8% in patients who lived in rural areas when all positive cases were evaluated in terms of settlement areas. While Blastocystis spp., E. vermicularis and G. intestinalis were the most frequently detected intestinal parasites in our province, intestinal parasites still remain important despite advances in infrastructure in recent years.Item The in vitro effects of azithromycin and Clarithromycin on promastigotes and amastigotes of Leishmania tropica; [Leishmania tropica promastigotları ve amastigotları üzerine azitromisin ve klaritromisinin in vitro etkisi](Veteriner Fakultesi Dergisi, 2012) Balcioğlu İ.C.; Ok Ü.Z.; Özbel Y.; Girginkardeşler N.; Özbilgin A.Leishmania (L.) tropica is one of the most common species responsible for cutaneous leishmaniasis (CL) in the Old World including Turkey. The pentavalent antimonials are widely used as intralesional and/or intramuscular in the treatment of CL, but increase in resistance to these agents led to investigations on alternative drugs. In vitro antileishmanial activities of two macrolides, azithromycin and clarithromycin were evaluated on promastigotes in RPMI 1640 medium and amastigotes in macrophage series of L. tropica. ED50 values of azithromycin and clarithromycin were found to be 5 µg/ml and <5 µg/ml on promastigotes, and 50-75 µg/ml and <3 µg/ ml on amastigotes, respectively, while ED90 values of the same drugs were 75 µg/ml and 25 µg/ml on promastigotes and 100 µg/ml and 10 µg/ml on amastigotes, respectively. Our data suggested that clarithromycin and azithromycin were effective on both L. tropica promastigotes and amastigotes in vitro. Clarithromycin was found to be more effective than azithromycin at lower concentrations on promastigotes and amastigotes. In vivo studies should be planned to detect intracellular concentrations of these drugs for the effective route and dosage. © 2012, Veteriner Fakultesi Dergisi.

A total of 2091 children (1565 in Osmancalı and 526 in Maldan) were combed with a newly-designed lice comb (PDC®, KSL Consulting, Helsinge, Denmark) four times in May and November in 2008 and 2009. The assessment of the results was conducted with SPSS® v.15 program using CHAID and logistic regression analysis. The results of the periodic examinations of the children showed that the infestation rate of girls were found to be higher significantly compared to boys (P<0.001), and the incidence of head lice infestation in boys from Osmancalı was found three times higher than the incidence in boys in Maldan (P=0.002). In addition, regular dry combing and treatment lowered the infestation rates among girls significantly (P=0.001). According to the results of the study, regular dry combing of school children with specially-designed lice combs may be essential for the control of this common infestation, especially in rural areas. © 2012, Veteriner Fakultesi Dergisi.

Anti-Toxoplasma gondii IgG and IgM antibodies were investigated by IFAT, IgG ELISA, and IgM Capture ELISA in 2815 patients. IgG avidity tests were also performed in cases with both IgG and IgM seropositivity. Only IgG, only IgM and both IgG and IgM seropositivity were detected in 657 (23.3%), 4 (0.1%) and 6 (0.2%) cases respectively among 2815 patients. Anti-T. gondii IgG seropositivity was mostly found in patients [21.2% (n=139)] who consume raw meat. IgG seroprevalence was found to be statistically higher in the 15-49 age group than the 0-14 age group (p < 0.05). Decrease in the prevalence of anti- T. gondii IgG seropositivity in 2010 was found to be statistically significant considering the five years period (p < 0.001). Raw meat consumption was detected as the most important risk factor in Toxoplasma infection. A decrease in anti-T. gondii IgG antibodies was detected in recent years considering the five years' serologic data, but toxoplasmosis remains important as a public health problem in Manisa.Item A mass screening survey of cystic echinococcosis by ultrasonography, Western blotting, and ELISA among university students in Manisa, Turkey(2013) Kilimcioǧlu A.A.; Girginkardeşler N.; Korkmaz M.; Özkol M.; Düzgün F.; Östan T.; Pabuşcu Y.; Dinç G.; Ok T.Z.Cystic echinococcosis (CE) is one of the most important zoonotic diseases in a wide geographic area, including Turkey. In the present project, a total of 4275 students from Celal Bayar University, Manisa, Turkey, were screened by ultrasonography (US) and specific antibodies for CE were examined by Western blotting (WB) and ELISA in finger prick blood samples of 2034 of 4275 volunteered students. We aimed to report the apparent prevalence of CE based on different diagnostic procedures and to compare WB and ELISA with US in diagnosis of CE in a mass screening setting. Six new cases were diagnosed as CE by US during the survey. In addition to these cases, three students were also detected to have been previously operated and pathologically confirmed for hepatic CE. US revealed parenchymal changes in these cases in concordance with their operation history; so, the prevalence of CE by US was calculated as 0.21% (9/4275) (95%CI, 0.11-0.39%) among university students in Manisa. Bands were detected at 8, 28, 32, 38, 42, 47, 70 and 90. kDa by WB and the cases were considered to be positive for CE when at least three of the bands were seen together. Apparent prevalence of CE by ELISA and WB were found to be 2.11% (43/2034) (95%CI, 1.57-2.83%) and 0.25% (5/2034) (95%CI, 0.10-0.57%), respectively. Of the six US positive cases, WB was positive in only one case with two cysts in the liver. All of four cases with liver involvement were positive by ELISA. The high prevalence of CE among university students in Manisa indicated that CE is a major health problem in this area of Turkey. Our results supported that WB is rather difficult and not feasible as a mass screening test and may not be effective for confirmation especially in asymptomatic cases. As a result, we recommend US to be used initially in mass screening surveys for CE followed by confirmation by ELISA for suspected cases. Further examination primarily by chest X-ray followed by computed tomography and/or magnetic resonance imaging, if needed, should be recommended for US negative, ELISA and WB positive individuals who may have non-abdominal cysts. © 2013 Elsevier B.V.Item Evaluation of 131I-Pentamidine for scintigraphy of experimentally Leishmania tropica-infected hamsters(Informa Healthcare, 2014) Inceboz T.; Lambrecht F.Y.; Eren M.Ş.; Girginkardeşler N.; Bekiş R.; Yilmaz O.; Er Ö.; Özbilgin A.We aimed to assess the ability of 131I-Pentamidine scintigraphy to detect the lesions of Leishmania tropica infection. An experimental model of cutaneous leishmaniasis was developed. The presence of cutaneous leishmaniasis was confirmed. Pentamidine was radioiodinated with 131I. The radiolabeled pentamidine was validated by the requisite quality control tests to check its radiolabeling efficiency, in vitro stability. 131I- Pentamidine (activity: 18.5 MBq/100 l) was injected intracardiacally into infected hamsters. Static whole body images of the hamsters were acquired under the gamma camera at 5 and 30 in, 2, 6 and 24 h following the administration. On the scintigrams, anatomically adjusted regions of interest (ROIs) were drawn over the right feet (target) and left feet (not-target) and various organs. Accumulation of 131I-Pentamidine at sites of infection is expressed as the target to non-target (T/NT) ratio. The results T/NT ratio decreased with time. In concluding the 131I-Pentamidine has poor sensitivity in detection of L. tropica infection. © 2014 Informa UK Ltd.

Specially designed combs are used to identify head lice, while anti-lice products are applied on the scalp for treatment. In the present study, we aimed to test whether combing only by precision detection comb (PDC) or metal pin comb (MPC) could be effective alternatives to the use of anti-lice products in children. A total of 560 children from two rural schools in Turkey were screened. In the PDC trial, children were combed every second day for 14 days, while in the MPC trial, combing was performed once in every four days for 15 days. Children were divided into two groups (dry combing and wet combing) for both trials and results were compared. The results showed no significant differences between dry and wet combing strategies for both combs for the removal of head lice (p > 0.05). The number of adult head lice declined significantly on each subsequent combing day in both approaches, except on day 15 in the MPC trial. In the end, no louse was found in 54.1 and 48.9 % of children in the PDC and MPC trials, respectively. Since family members of infested children were not available, they were not checked for HLI. Four times combing within 2 weeks with MPC combs was found effective for both treatment of low HLI and prevention of heavy HLI. In conclusion, regular combing by special combs decreases HLI level in children and is safely applicable as long-term treatment. © 2015, Springer-Verlag Berlin Heidelberg.Item Coexistence of Helicobacter pylori and Intestinal Parasitosis in Children with Chronic Abdominal Pain(2016) Gökşen B.; Appak Y.Ç.; Girginkardeşler N.; Ecemiş T.; Kasırga E.OBJECTIVE: The aim of this study was to determine the incidence of coinfection with Helicobacter pylori and intestinal parasitosis in children with chronic abdominal pain (CAP) and to investigate the common risk factors in the development of both infections.; METHODS: Ninety patients with CAP were enrolled in this study. Blood samples of each case were screened for human preformed IgG (HpIgG) antibodies, and stool samples were tested for HpSA and also examined for intestinal parasites by direct wet-mount, formalin-ethyl-acetate concentration, and Trichrome staining procedures. Cellophane tape test was used for Enterobius vermicularis. Children tested positive for HpIgG and/or HpSA were accepted as H. pylori positive. The risk factors were compared with a questionnaire.; RESULTS: The incidence of Giardia intestinalis was 14.8% in the H. pylori-positive group and was found to be statistically higher than that in the H. pylori-negative group (1.6%). The positivity rates of H. pylori were found to be statistically higher in children attending school and using drinking water from taps. The incidences of parasitosis were significantly higher in children with a low maternal education level and with a history of parasitosis treatment in the family.; CONCLUSION: The most common etiologies of CAP in children are H. pylori infection and intestinal parasitosis. İmprovement of hygienic conditions would be beneficial in preventing both infections.Item Investigation of Dientamoeba fragilis Prevalence and Evaluation of Sociodemographic and Clinical Features in Patients with Gastrointestinal Symptoms(Springer, 2019) Aykur M.; Calıskan Kurt C.; Dirim Erdogan D.; Biray Avcı C.; Vardar R.; Aydemir S.; Girginkardeşler N.; Gündüz C.; Dagci H.Background: Dientamoeba fragilis is a protozoan parasite of the human gastrointestinal tract and still controversial in association with gastrointestinal symptoms. Purpose: We present cross-sectional study of the prevalence of D. fragilis, and sociodemographic and clinical features in the patients with gastrointestinal symptoms. Methods: A total of 490 fecal specimens were collected from outpatients with gastrointestinal symptoms in the Department of Parasitology, Faculty of Medicine, Ege University and Celal Bayar University, Turkey. Fecal specimens were examined with microscopy and inoculated in Robinson medium. D. fragilis-positive samples were examined for the presence of other intestinal parasites using enzyme immunoassay. Real-time PCR analysis was performed on all samples. Results: Of the 490 stool specimens examined by real-time PCR, 59 patients were positive for D. fragilis infection with prevalence rate of 12.04%. Forty-four of positive patients (74.5%) were found to be infected with only D. fragilis, while 23.7% were co-infected with Blastocystis and 1.7% were co-infected with Rotavirus. No statistically significant difference was found in all the examined patients in terms of D. fragilis positivity for all sociodemographic parameters. Loose stool consistency was associated with the presence of D. fragilis, with 18.3% (P = 0.001). When the clinical symptoms of all the patients participating in this study were examined, diarrhea was statistically more significant in patients with the presence of D. fragilis (16.3%; P = 0.001). The rate of diarrhea in D. fragilis-positive patients (84.09%; P = 0.0005) was higher than that of D. fragilis-negative patients and it was statistically significant. Conclusion: This study is important for assessing the prevalence of D. fragilis and its association with other factors in symptomatic patients in a large sample group in Turkey, as well as investigating the relationship of identified symptoms with the D. fragilis pathogenicity. It is suggested that D. fragilis in this case is not a commensal parasite but a pathogenic parasite and that the most common clinical symptom is diarrhea. © 2019, Witold Stefański Institute of Parasitology, Polish Academy of Sciences.Item Investigation of the Anti-Leishmanial Effects of Prangos ferulacea and Ferula orientalis Extracts Collected from Şırnak Province Against Leishmania tropica İsolated in Turkey; [Şırnak İli ve Çevresinden Toplanan Prangos ferulacea ve Ferula orientalis Ekstrelerinin Türkiye’den İzole Edilmiş Leishmania tropica’ya Karşı Anti-Leishmanial Etkilerinin Araştırılması](Ankara Microbiology Society, 2022) Babat S.Ö.; Çavuş I.; Özbilgin A.; Kayalar H.; Gündüz C.; Ceylan Ş.S.; Girginkardeşler N.Leishmaniasis is a vector-borne disease that is caused by the protozoa of Leishmania genus. Leishmaniasis is endemic in tropical, subtropical, and large areas of the Mediterranean basin, and covers a total of 98 countries worldwide. It is estimated, according to the World Health Organization (WHO) data, that approximately 350 million people are at risk in these areas, and approximately 12 million people are infected. Increased drug resistance has been documented lately, in the treatment of leishmaniasis which causes almost 1.2 million new cases annually. Thus, interest in plant-derived active substances has increased in recent years, and new anti-leishmanial agents are investigated with in vitro studies. The aim of the present study was to investigate the anti-leishmanial effects of Prangos ferulacea and Ferula orientalis plant extracts collected from the rural areas of Şırnak province against Leishmania tropica. The water, chloroform, and ethanol extracts of the roots, stems, and fruits of P.ferulaceae and F.orientalis plants were obtained, and the cytotoxic activity tests of the extracts were performed. L.tropica isolate obtained from the Parasite Bank in Manisa Celal Bayar University in Turkey (MHOM/TR/2012/CBCL-LT) was grown on NNN and RPMI 1640 broth medium. The cytotoxicity of each extract on the L.tropica isolate was evaluated with the XTT test. Amphotericin B (AmpB) was used as the positive control, and the IC50 values were determined. The lowest IC50 values of the plant extracts were found to be as follows: P.ferulaceae root chloroform extract 36 µg/ml and fruit chloroform extract 20 µg/ml, F.orientalis root ethanol extract 2.5 µg/ml, and fruit ethanol extract 48 µg/ml, stem chloroform extract 24 µg/ml, and fruit chloroform extract 3.1 µg/ml. It was also determined in our study that only P.ferulaceae root ethanol extract showed cytotoxic activity on the WI-38 fetal lung fibroblast cell line at 65.19 µg/ml at 72 hours. This is the first study that assessed the anti-leishmanial activities of P.ferulaceae and F.orientalis plants that grow in high altitude areas of our country. It was determined that P.ferulaceae root ethanol extract and fruit chloroform extract had the lowest IC50 values among the 18 plant extracts that we examined for their anti-leishmanial activities. The outcomes of this study will be useful in further studies for the determination of active compounds in P.ferulaceae and F.orientalis plant extracts. © 2022 Ankara Microbiology Society.
