    (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.

    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. Trial Registration. Current Controlled Trials ISRCTN10431107.

    Are regular controls conducted in schools adequate in lowering the incidence of head lice (Pediculus capitis) infestation?; [Okullarda düzenli aralıklarla gerçekleştirilen kontroller saç biti (Pediculus capitis) insidansını düşürmekte yeterli olabilir mi?]
    (Veteriner Fakultesi Dergisi, 2012) Balcioğlu İ.C.; Kurt Ö.; Limoncu M.E.; Ermiş V.Ö.; Tabak T.; Oyur T.; Muslu H.; Kavur H.; Görgün S.; Girginkardeşler N.; Yereli K.; Bilaç C.; Özbel Y.
    In the present study, school children of similar age-groups from two villages of Manisa province, namely Osmancalı and Maldan, were examined in regular time periods to monitorize the changes in the incidence of head lice (Pediculus capitis). 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.

    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).

    Analysis of morphological variations of three Adlerius (Diptera: Psychodidae) species collected in two cutaneous leishmaniasis endemic foci of Turkey
    (Springer Science and Business Media Deutschland GmbH, 2022) Kavur H.; Arikan H.; Toz S.; Balcioglu I.C.; Ozbel Y.
    Leishmaniasis, transmitted to human by sand flies, is a neglected vector-borne diseases and has two clinical forms: cutaneous (CL) and visceral leishmaniasis (VL) in Turkey. Subgenus of Adlerius are known as probable vectors of both forms of leishmaniasis in Turkey. Examined three species belonging to Adlerius are difficult to distinguish morphologically and have similar taxonomic characters. The aim of this study was to analyse and identify the possible morphological variations, of wild-caught sand fly specimens belonging to Adlerius subgenus. Six and seven morphological characters for female and male specimens were used, respectively. ANOVA, principal component analysis (PCA) and discriminant function analysis (DFA) test were performed to determine the significant morphometric variables of the three species. Univariate and multivariate analyses of 13 morphometric variables via ANOVA, DFA and PCA showed that eight (six for females, two for males) morphometric variables had an accuracy of 100% for discriminating three Adlerius subgenus specimens. The analyses revealed significant differences on several morphological structures of Adlerius specimens. These results suggested that morphological and morphometrical features can be used to discriminate three Adlerius species, in which one of them is proven vector Leishmania (L.) tropica in two foci of Turkey. © 2021, African Association of Insect Scientists.
