Öğe A Serologic Survey on Canine Leishmaniasis in Kocaeli, Sakarya, Mersin and Elazig Provinces of Turkey(Israel Veterinary Medical Assoc, 2018) Utuk, A. E.; Gokmen, Guven T.; Bolacali, M.; Balkaya, I; Simsek, S.The aims of this pilot study were to determine the seroprevalence of canine leishmaniasis in Kocaeli, Sakarya, Mersin and Elazig provinces and make a general evaluation of the serologic prevelence of Canine Leishmaniasis (CanL) in Turkey. For this purpose, 111 sera were collected from dogs of different breeds, ages and sexes. Anti-Leishmania IgG antibodies were detected with a commercially available IFAT kit. The relationship between location, breed, age, sex and the seropositivity were evaluated with Chi Square (X-2) test. At the end of the study, the overall seroprevalence was determined as 7.20% (8/111). Seroprevalance rates were 5%, 10.52% and 18.75% in Sakarya, Kocaeli and Mersin provinces, respectively; however, no antibodies were detected in dogs from Elazig. There was no statistical difference in breed, sex and age groups (P>0.05). The prevalence of infection in the province of Mersin was significantly higher than in Elazig (p<0.05). The mean seroprevalence of CanL was calculated as 7.29% for Turkey, which is similar to our results (7.20%). In this study, we gave information about the serostatus of CanL in four different provinces of Turkey. We consider that further studies are required for a clearer understanding of the parasite epidemiology and effective control measures.Öğe A serologic survey on canine leishmaniasis in Kocaeli, Sakarya, mersin and elazığ Provinces of Turkey(Israel Veterinary Medical Association, 2018) Utuk, Armağan Erdem; Guven Gokmen, T.; Bolacali, M.; Balkaya, I.; Simsek, S.The aims of this pilot study were to determine the seroprevalence of canine leishmaniasis in Kocaeli, Sakarya, Mersin and Elazığ provinces and make a general evaluation of the serologic prevelence of Canine Leishmaniasis (CanL) in Turkey.

M.; Ozbay, E.The electronic structures of KNbO(3)were calculated within the density functional theory, and their evolution was analyzed as the crystal-field symmetry changes from cubic to rhombohedral via tetragonal phase. We carried out electron-energy loss spectroscopy experiments by using synchrotron radiation and compared the results with the theoretical spectra calculated within Density Functional Theory. The dominant role of the NbO(6)octahedra in the formation of the energy spectra of KNbO(3)compound was demonstrated. The anomalous behavior of plasmons in ferroelectrics was exhibited by the function representing the characteristic energy loss in the region of phase transition.Öğe Genetic, haplotype and phylogenetic analysis of Ligula intestinalis by using mt-CO1 gene marker: ecological implications, climate change and eco-genetic diversity(Instituto Internacional de Ecologia, 2024) Selcuk, M.A.; Celik, F.; Simsek, S.; Ahmed, H.; Kesik, H.K.; Kilinc, S. Gunyakti; Cao, J.Ligula intestinalis is a cestode parasite that affects freshwater fish in different countries of the world. The current study aims to reveal the phylogenetic, genetic and haplotype diversity of mt-CO1 gene sequences sent to the NCBI database from different countries by using in-silico analysis. The 105 mt-CO1 (371 bp) gene sequences of L. intestinalis obtained from NCBI were used for bioinformatics analyses. Sequences were subjected to phylogenetic and haplotype analysis. As a result of the haplotype analysis of L. intestinalis, 38 haplotypes were obtained from 13 different countries. Hap24 constituted 44.76% of the obtained haplotype network. Changes in nucleotides between haplotypes occurred at 1-84 different points. China and Turkey have highest fixation index (Fst) values of 0.59761, while the lowest (-0.10526) was found between Russia and Turkey. This study provides a baseline for future studies on extensive scale on the epidemiology, ecological aspects, distribution pattern, transmission dynamics and population dispersion of L. intestinalis worldwide. © 2024, Instituto Internacional de Ecologia.
