Item Efficacy of azithromycin in a murine toxoplasmosis model, employing a Toxoplasma gondii strain from Turkey(Elsevier, 2003) Deǧerli K.; Kilimcioǧlu A.A.; Kurt Ö.; Tamay A.T.; Özbilgin A.A murine toxoplasmosis model with Balb/C mice was used to investigate the therapeutic and prophylactic efficacy of azithromycin in a native strain of Toxoplasma gondii. Initially, seven groups - four studies and three controls - were established and 103 tachyzoites of this native strain of T. gondii were injected intraperitoneally to the mice in groups 1, 2, 3, 4 and 7. Azithromycin was given to groups 1-4 at different times of infection orally between 100 and 300 mg/kg/day for 10 days. Azithromycin was found to be effective at 200 mg/kg/day and above in the prophylaxis, at 250 mg/kg/day and above in the treatment of toxoplasmosis. These results suggest that azithromycin is effective in the prophylaxis and early infection of a highly virulent strain of T. gondii, and it doubled the survival time in the late infection. Azithromycin could be an alternative treatment regimen for human toxoplasmosis, if supported by further clinical investigations. © 2003 Elsevier B.V.

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. All rights reserved.Item The value of ultrasonography alone in screening surveys of cystic echinococcosis in children in Turkey(2006) Kilimcioǧlu A.A.; Özkol M.; Bayindir P.; Girginkardeşler N.; Östan I.; Ok Ü.Z.A total of 1205 primary school children were examined for cystic echinococcosis in five villages of Manisa, Turkey, to evaluate the efficacy of diagnostic methods of this infection in community-based screening surveys. 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.

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.

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 Two novel serum-free media for the culture of Trichomonas vaginalis(2007) Limoncu M.E.; Kilimcioǧlu A.A.; Kurt Ö.; Östan I.; Özkütük N.; Özbilgin A.Definitive diagnosis of Trichomonas vaginalis, one of the common causes of sexually transmitted diseases in Turkey, relies on the microscopic examination of both fresh preparations and culture material of genital secretions and urine. The aim of this study was to compare the diagnostic efficacies of two culture media, serum-free TB1 and TB2, including iron and vitamin B12, respectively, with the well-known medium, TYM. Growth rate reached peak levels 48 h in TYM and 72 h in both TB1 and TB2 after inoculation. The highest amount of viable trophozoites has been obtained from TB1, almost equal to TYM but significantly higher than TB2. Fresh preparations obtained from the vaginal secretions of 119 patients have been examined and vaginal samples have been inoculated in TB1, TB2, and TYM. Viable T. vaginalis trophozoites have been detected in ten (8.4%) of fresh preparations and 11 (9.9%) of each medium. It is concluded that serum-free TB1 medium could be used effectively in both the isolation and maintenance of T. vaginalis culture in vitro. © 2006 Springer-Verlag.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.

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 [Incidence of intestinal parasites detected in the Department of Parasitology in Celal Bayar University Hospital between 2006 and 2010].; [Celal Bayar Üniversitesi Hastanesi Parazitoloji Polikliniǧi'nde 2006-2010 Yillari Arasinda Saptanan Baǧirsak Parazitlerinin İnsidansi](2012) Düzyol D.; Kilimcioǧlu A.A.; Ozyurt B.C.; Ozkan H.; Girginkardeşler N.Results of 17.711 patien admitted to the Department of Parasitology in Celal Bayar University Hospital for parasitological stool examination between January 2006 and December 2010 were evaluated. 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 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.
