Item Serological levels of zinc, copper and iron elements among Giardia lamblia infected children in turkey(2002) Ertan P.; Yereli K.; Kurt Ö.; Balcioǧlu I.C.; Onaǧ A.Background: Giardiasis, an intestinal protozoan infection caused by Giardia lamblia, is common in Turkey, especially among children aged between 2- and 14-years-old. Effects of giardiasis on serological levels of zinc, copper and iron elements were assessed in this study. Methods: A total of 45 children, aged between 2- and 14-years-old, who were admitted to the Pediatrics Department of Celal Bayar University Medical School with gastrointestinal complaints and diagnosed as having giardiasis by stool examinations in the Parasitology Department, were enrolled as the study group (SG). The control group (CG) consisted of 45 age-matched healthy children. Serological levels of zinc, copper and iron were measured by atomic absorption spectrophotometer in all samples. Results: As a result of the study, serum zinc levels were 67.43 ± 17.72 μg/dL and 145.20 ± 9.13 μg/dL, copper levels were 198.45 ± 39.14 μg/dL and 150 ± 21.14 μg/dL and iron levels were 87.98 ± 18.31 μg/dL and 160.45 ± 45.40 μg/dL, in SG and CG, respectively. When compared separately as SG and CG, there was a statistically significant difference between the serological levels of all these elements. Conclusion: These results revealed that giardiasis increased the serological levels of copper, like other infectious agents. However, zinc and iron levels decreased during giardiasis due to malabsorption.Item Leishmaniasis in Turkey(2002) Ok Ü.Z.; Balcioǧlu I.C.; Taylan Özkan A.; Özensoy S.; Özbel Y.Leishmaniases are widespread in most countries in the Mediterranean basin, including Turkey. Two forms are observed in Turkey; Leishmania infantum is responsible from visceral leishmaniasis (VL), and L. tropica causes cutaneous leishmaniasis (CL). Phlebotomus sergenti, P. papatasi, P. major and P. syriacus are considered to be the probable vectors, and dogs are the main reservoir of L. infantum, while P. sergenti is the main suspected vector of L. tropica. VL is sporadically seen mainly in the Aegean, Mediterranean, and Central Anatolia Regions, but CL is endemic, especially in the Southeastern and Mediterranean Regions. Major touristic sites are free of both infections, and no infection is reported in any tourist. Mean number of annual VL and CL cases reported to Ministry of Health are 40 and 1,204, respectively, in the last four years. These data suggest that both VL and CL represent a public health problem in Turkey, but a decline is observed in the number of cases with both infections in recent years. © 2002 Elsevier Science 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.

The significant causes of this problem are the insufficient resources to improve the infrastructure in these regions and inadequate health services in both the diagnosis and treatment of diseases. The aim of this study was to assess the association between intestinal parasitic infections and clinical symptoms of infected children. Cellophane tape and stool samples of 100 children, aged between 7-10 years, from two villages of Manisa city, were examined for intestinal parasites and their symptoms were recorded. Although some symptoms, such as abdominal pain, anorexia and fatigue were found to be common in infected children, no significant relationship was found between symptoms and intestinal parasitic infections. © 2005 Bioscience Ediprint Inc.Item Is Toxoplasma gondii a potential risk for traffic accidents in Turkey?(Elsevier Ireland Ltd, 2006) Yereli K.; Balcioǧlu I.C.; Özbilgin A.In Turkey, traffic accidents are the major causes of mortality and morbidity. According to the statistics made by Turkish Security Headquarters in the year 2000, 7500 people are killed in the traffic accidents every year. Drivers are mostly blamed for the traffic accidents. Tired, weary, sleepy and absentminded driving are common reasons for traffic accidents due to many reasons. Among these reasons mental and reflex conditions of drivers are significant. Toxoplasmosis is one of the most common zoonoses throughout the world. In immunocomponent adults, toxoplasmosis has no clinical signs or symptoms and infection in such people can only be detected by serological examinations. This kind of latent or dormant toxoplasmosis can be located in neural or muscular tissues and cause prolonged reaction times of the muscles. Extended reaction times also lead to deceleration of the reflexes which could be a major cause of the traffic accidents. By the light of this situation, the incidence of Toxoplasma gondii is investigated among the population who were involved in a traffic accident while driving. A total of 185 people (100 men and 85 women), aged between 21 and 40 years, living in Izmir and Manisa cities, were enrolled in the study group (SG) during a period of 6 months time. Their informed consents were taken initially and the laboratory tests of all these individuals related to blood alcohol levels after the accidents were found negative. The control group (CG) were also consisted 185 people (95 men and 90 women), residents of the same region, in same age group. The people in CG had no clinical signs or symptoms concerning toxoplasmosis. All collected sera were examined using a commercial IgG and IgM ELISA kit. According to the results of serological tests of the SG, 45 (24.32%) sera were IgG positive, six (3.24%) were IgM positive and 10 (5.40%) were both IgG and IgM positive. On the other hand in CG, 12 (6.48%) people found IgG positive, one (0.54%) found IgM positive and three (1.62%) found both IgG and IgM positive. This data was considered as statistically significant by Yates corrected χ2-test. (p < 0.05). In conclusion, there is an increased risk for traffic accidents for drivers owing to these high seroprevalence of latent toxoplasmosis. Prospective studies are still necessary on this subject but latent toxoplasmosis of drivers should be taken into account while developing strategies to prevent traffic accidents in Turkey. © 2005 Elsevier Ireland Ltd.

He had been diagnosed with isosporiasis during a field study, conducted in a village of Manisa province, during an investigation of the incidence of intestinal parasites.Item A comparison of metronidazole and single-dose ornidazole for the treatment of dientamoebiasis(Blackwell Publishing Ltd, 2008) Kurt Ö.; Girginkardeşler N.; Balcioǧlu I.C.; Q̈zbilgin A.; Ok Ü.Z.Recent reports of the pathogenic potential of Dientamoeba fragilis have underlined the need for an effective treatment against this colon-dwelling protozoan. 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 Subungual myiasis in a woman with psychiatric disturbance(2008) Balcioǧlu I.C.; Ecemiş T.; Ayer A.; Özbel Y.Myiasis is caused by the invasion of tissues or organs of men and animals by dipterous larvae. The disease is infrequent in Turkey. A case of a 65-year-old woman having been initially diagnosed with chronic psychosis, and found to have a left big toe nail invaded by the larvae of Calliphora spp., is presented. A total of 17 maggots were removed from the left big toe of the patient, which were then determined as Calliphora spp. The patient has undergone surgical withdrawal of both nails of her big toes, followed by the administration of oral prophylactic antimicrobial treatment. This is the second recorded case of subungual myiasis by Calliphora spp. in Turkey. Myiasis should be considered in patients with lower personal hygiene, especially with chronic psychiatric disturbances. © 2008 Elsevier Ireland Ltd.

A relationship between canine leishmaniasis (CanL) and HVL has been detected and dogs have been found to be the reservoir of Leishmania infantum. In this epidemiologic study, the seroprevalence of CanL was investigated in dog shelters of four districts (Kepez, Kemer, Alanya and Gazipasa) of Antalya, in which visceral leishmaniasis and cutaneous leishmaniasis were observed according to the official records of The Ministry of Health of Turkey. Blood specimens of 176 dogs were examined and seropositive, borderline, seropositive, and negative results were detected in 14 (7.95%), 24 (13.63%), and 138 (78.4%) dogs, respectively. Weight and alopecia, onychogryphosis, and skin ulcers around the nose were observed in only two (14.2 %) dogs of seropositive cases. In conclusion, our data indicate that there is a potential danger for humans because L. infantum carrying dogs were detected in four districts of Antalya in the present study and also the appropriate vector spp. for this parasite has been reported in a previous one. Therefore, it would be advisable to perform new studies in order to determine the seroprevalence of CanL in dogs and the population size of vector spp. of L. infantum in other districts of Antalya.Item Comparison of two combs in the detection of head lice in school children.(2009) Kurt O.; Tabak T.; Kavur H.; Muslu H.; Limoncu E.; Bilaç C.; Balcioǧlu I.C.; Kaya Y.; Ozbel Y.; Larsen K.The diagnostic efficacies of two metal pin lice combs having different spacing between their teeth were compared in two cohorts of school children, aged between 7 and 15 years, from different villages of Manisa, Turkey. Head lice infestation was evaluated with comb A (0.18 mm of distance between the teeth) in 95 children in Cavusoglu village, and with comb B (0.15 mm of distance between the teeth) in 146 children in Yesilköy village, compared to visual inspection. Five of 95 (5.3%) children in Cavusoglu village and 5 of 146 (3.4%) children in Yesilköy village were found to harbor live head lice with combing, while none was detected during the visual inspection. The difference between the infestation rates of two cohorts was statistically insignificant (p > 0.05). With visual screening, 15 and 16 children with louse eggs were identified in Cavusoglu and Yesilköy villages, respectively. With combing in these villages, 5 and 8 children, respectively, with louse eggs were identified and 3 and 5 children, respectively, were detected only with combing, not with visual screening. In conclusion, combing is more effective than visual inspection in head lice detection, but there were no significant difference between the two combs either in lice detection or in usage.Item Treatment of head lice with dimeticone 4% lotion: Comparison of two formulations in a randomised controlled trial in rural Turkey(2009) Kurt Ö.; Balcioǧlu I.C.; Burgess I.F.; Limoncu M.E.; Girginkardeşler N.; Tabak T.; Muslu H.; Ermiş Z.; Sahin M.T.; Bilac C.; Kavur H.; Özbel Y.Background. 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.

The entomological survey was carried out during 2006-2007 in a study area in the rural area of Aydin province, near the Kusadasi town where VL, CL, and canine leishmaniasis (CanL) are endemic. In 2006 and 2007, 132 locations were sampled using sticky traps mainly on embankments. Detailed environmental and meteorological information was also collected for each location. The results of entomological studies indicated that the probable vectors are Phlebotomus tobbi and P. neglectus for VL and CanL, and P. similis for CL in this western leishmaniasis focus. The data revealed a correlation between their presence and spatial variables such as altitude, sampling site location, and humidity. The distribution areas of probable vector species in this study area allowed the identification of risk levels, which may provide useful information to guide the leishmaniasis research in endemic regions. © 2011 The Society for Vector Ecology.Item Investigation of in vitro antileishmanial activity of moxifloxacin, linezolid and caspofungin on Leishmania tropica promastigotes.(2013) Limoncu M.E.; Eraç B.; Gürpinar T.; Özbilgin A.; Balcioǧlu I.C.; Hoşgör-Limoncu M.This study aimed to evaluate the potential in vitro anti-leishmanial activities of moxifloxacin, linezolid and caspofungin against Leishmania tropica. In vitro effects of all agents were studied by using the microdilution method. For this purpose, serial dilutions of the aforementioned agents were prepared in concentrations between 4096 μg/mL-0.008 μg/mL. Afterwards, promastigotes incubated in suitable medium were counted with the hemocytometer and adjusted as having a last concentration of 2.5 x 10(6) cells/mL in wells containing medium+antibiotic or antifungal. After incubation live promastigotes were counted with the hemocytometer and inhibitor concentrations (IC(50)) were determined by comparing with the control that contained no antibiotics or antifungal. IC(50) values of moxiloxacin, linezolid and caspofungin were found as 194.7 μg/mL, 896 μg/mL and 235.7 μg/mL, respectively. As a result, moxifloxacin was found to be effective in lower concentrations than the other studied agents against L. tropica promastigotes.Item Entomological survey for the detection of sand fly fauna and vector species in the cutaneous leishmaniasis endemic area in east mediterranean region of Turkey, Mersin province(Oxford University Press, 2020) Limoncu M.E.; Balcioǧlu I.C.; Töz S.; Demir S.; Kavur H.; Karakuş M.; Vardarli A.T.; Özbel Y.Cutaneous (CL) and visceral (VL) forms of leishmaniasis, transmitted by sand flies, are seen in all countries located in Mediterranean Basin including Turkey. In this study, we aimed to conduct an entomological survey for the detection of sand fly fauna and vector species in Mersin province, one of the important endemic areas for CL in Turkey. In total, 912 sand fly specimens were collected in 2010 and 2011 using CDC light traps. Nine Phlebotomus (Diptera: Psychodidae) and three Sergentomyia (Diptera: Psychodidae) species were detected. Of the collected Phlebotomus sand flies, P. sergenti Parrot, 1917 (30.1%) was the most dominant followed by P. alexandri Sinton, 1928 (18.2%), P. neglectus/syriacus Tonnoir Adler (12.0%), P. tobbi Adler & Theodor, 1930 (11.7%), and P. papatasi Scopoli, 1786 (10.2%), while S. minuta Rondani, 1843 (11.3%) was the dominant species among Sergentomyia. During the field work in 2011, female specimens (n = 81) were screened for the presence of Leishmania promastigotes by midgut dissection, and all were found negative. The rest of the collected female specimens (n = 334) were pooled according to species (P. alexandri, P. neglectus/syriacus, P. papatasi, P. sergenti, P. simici, and P. tobbi) and location (Mut, Silifke, and Anamur). In total, 29 pools were generated and real-time ITS1 PCR assay was performed to detect and identify natural Leishmania Ross, 1903 (Kinetoplastida: Trypanosomatida) infection. Two pools, both from Mut town, containing P. sergenti specimens were found positive and Leishmania tropica Ross, 1903 was identified as an infectious agent for both pools. In conclusion, the sand fly fauna was determined in an endemic area for CL. The detection of L. tropica DNA in P. sergenti specimens showed the possible vectorial role of this species in Mersin province. © 2020 The Author(s).Item Investigation of Leishmania RNA Virus 2 in Leishmania major and Leishmania tropica Strains Isolated from Cutaneous Leishmaniasis Patients in Türkiye; [Türkiye'deki Kutanöz Leyşmanyazis Hastalarindan Izole Edilen Leishmania major ve Leishmania tropica Izolatlarinda Leishmania RNA Virüsü 2'nin Araştirilmasi](Ankara Microbiology Society, 2023) Karabulut C.; Aksoy T.; Yildirim A.; Balcioǧlu I.C.Leishmania RNA virus (LRV) is a double-stranded RNA (dsRNA) virus that is thought to contribute to the severe inflammatory response of the causative Leishmania parasite in the mammalian host by being present in many isolates of Leishmania spp. In our study, it was aimed to obtain data on the presence of Leishmania RNA Virus 2 (LRV2), which is thought to cause a change in the clinical course of leishmaniasis, in Leishmania major and Leishmania tropica isolates isolated from cutaneous leishmaniasis (CL) patients in Türkiye. Leishmania strains stored in liquid nitrogen tank by cryopreservation in Manisa Celal Bayar University Faculty of Medicine Parasite Bank were resuscitated under suitable conditions and cultivated in NNN and RPMI-1640 media. Then, the isolates were allowed to enter the logarithmic phase in a 26°C incubator and DNA isolations were made using the "High Pure PCR Template Preparation Kit". Real-time polymerase chain reaction (Rt-PCR) melting analyzes were applied to the DNAs obtained by using primers and probes specific to the internal transcribed spacer-1 (ITS-1) gene region of Leishmania. After RNA isolation from promastigote suspension, cDNA synthesis was performed by reverse transcription. After gel electrophoresis with PCR amplification products, dsRNA band formation was evaluated in terms of LRV2 positivity under ultraviolet light. Among the 20 examined Leishmania spp. isolates (10 L.tropica and 10 L.major), four (three L.tropica, one L.major) were found to be positive for the presence of LRV2. Although the mechanism of LRV in recent studies has not been fully understood, it is known that it exacerbates the clinic of the disease and even has an effect on the formation of drug resistance by the parasite. It is important to obtain data on the presence of LRV in our country and to contribute to various clinical, drug development, prevalence studies, diagnosis and treatment of the disease in the future. © 2023 Ankara Microbiology Society.
