Item Trichomoniasis in non-gonococcic urethritis among male patients.(1994) Ozbilgin A.; Ozbel Y.; Alkan M.Z.; Gürüz Y.; Atambay M.; Tasçi S.; Ozcel M.A.Urethral discharge of 415 male patients, age 18-50, were examined for Trichomonas vaginalis by direct examination of fresh and Giemsa-stained slides and cultivation in CPLM media. In this study, 85 (20.7%) specimens out of 415, were found to be positive for trichomoniasis. Three groups consisting of 30, 29 and 26 patients each was treated with secnidazole, metronidazole and ornidazole respectively. In the follow up controls, all patients were found to be negative for trichomoniasis and all complaints were disappeared totally without a significant difference between all groups.Item Cultivation of Leishmania sp. in nutrient broth.(1995) Ozbilgin A.; Ozbel Y.; Alkan M.Z.; Atambay M.; Ozcel M.A.Bone-marrow aspiration and biopsy material samples obtained from two patients, one diagnosed as visceral and other as cutaneous leishmaniasis, were inoculated in Novy, McNeal, Nicolle (NNN) medium and nutrient broth (NB), containing fetal calf serum (FCS), penicillin and streptomycine. Both media were incubated at 27 degrees C for 10 days and observed daily for L. infantum and L. major promastigotes. Promastigotes were observed in nutrient broth after the first day, while in NNN media after the second or third day of incubation, indicating the effectiveness of nutrient broth in early diagnosis of both forms of leishmaniasis.Item Seroprevalence of canine visceral leishmaniasis in Kuşadasi, Turkey(TUBITAK, 2005) Özensoy Töz S.; Ertabaklar H.; Özbel Y.; Cüneyt Balcioǧlu I.; Yildizli N.; Alkan M.Z.Human and canine visceral leishmaniasis cases have been reported from Kuşadasi, a town in western Turkey, since 1993. In orcer to better understand the epidemiology of canine visceral leishmaniasis (CanVL) in the region, we aimed: (i) to determine the prevalence of CanVL in Kuşadasi using a randomly selected dog population and (ii) to measure the effect of case control on the prevalence of the disease. In this study, all 109 dogs kept at the dog shelter of Kuşadasi Municipality (reflecting random selectivity) were screened serologically using IFAT and rK39 ELISA in 1999. Ten dogs (9.1%) were seropositive or borderline in 1 of the 2 tests. Seropositive dogs (8) died spontaneously or were euthanized, while borderline dogs (2) underwent monthly serological examinations. One year later, in a second sampling, a total of 85 dogs were examined (27 previously tested and 58 new). Four dogs 4.7%) showed seropositivity. Seropositive dogs (2) were euthanized while borderline dogs (2) underwent monthly serological examinations. The reduction in the prevalence of the disease (from 9.1% to 4.7%) appears to be the result of culling CanVL positive dogs from the general population. © TÜBİTAK.Item Spatial distribution of phlebotomine sand flies in the Aydin Mountains and surroundings: The main focus of cutaneous leishmaniasis in western Turkey(2011) Özbel Y.; Balcioǧlu I.C.; Ölgen M.K.; Şimsek F.M.; Töz S.O.; Ertabaklar H.; Demir S.; Alkan M.Z.An entomological survey was conducted to determine the spatial distribution of phlebotomine fauna and understand the effect of environmental factors. 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 A new approach for determining the spatial risk levels for visceral and cutaneous leishmaniasis related with the distribution of vector species in western part of turkey using geographical information systems and remote sensing; [Coğrafi bilgi sistemleri ve uzaktan algılama kullanılarak türkiye’nin batısında visseral ve kutanöz leishmaniasisde vektör türlerin dağılımı ile ilişkili mekansal risk düzeylerinin saptanması için yeni bir yaklaşım](Veteriner Fakultesi Dergisi, 2012) Ölgen M.K.; Özbel Y.; Balcioğlu I.C.; Demir S.; Şimşek F.; Özensoy Töz S.; Ertabaklar H.; Alkan M.Z.Leishmaniases are present in two clinical forms, as visceral and cutaneous, in Turkey showing a tendency of spreading throughout the country. The aim of the present study was to produce a new model for determining the spatial risk levels using the data in a selected study site in the western part of Turkey. The results of entomological studies in this leishmaniasis focus indicated the presence of suspected vector species Phlebotomus (Larroussius) tobbi and P. (Larroussius) neglectus for the visceral, P. (Paraphlebotomus) similis for cutaneous forms of the disease. The new risk model was developed based on univariate and multivariate binary logistic regression analyses of geographical variables as altitude, aspect, Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI) and Land Surface Temperature (LST) values related to the distribution of these three species. The results of the new model were used to produce the risk maps and the potential distribution areas of the incriminated vector species with the use of geographical technologies which allowed the identification of the leishmaniasis risk levels that may provide useful information to guide the control program interventions. © 2012, Veteriner Fakultesi Dergisi.
