Background/purpose: The aim of the present study was to estimate the prevalence of Fasciola hepatica infection in sheep in the Black Sea region of Turkey., Methods: Samples from 213 sheep were collected randomly in Samsun, Tokat, and Sinop from September 2005 to January 2007 and tested by indirect enzyme-linked immunosorbent assay (ELISA) and Western blot analysis using F. hepatica excretory-secretory (E/S) antigens., Results: The distribution of ELISA-positive samples for F. hepatica infections out of a total of 213 sheep serum samples was 23/71 (32.4%), 15/59 (25.4%), and 29/83 (34.9%) in Samsun, Sinop, and Tokat, respectively. The immunodominant proteins were determined by Western blot analysis using molecular weight markers of 14 kDa, 20 kDa, 24 kDa, 27 kDa, 33 kDa, 45 kDa, and 66 kDa and extracted from sera of sheep that were positive for Fasciola spp. eggs and also hyperimmune sera from rabbits immunized with E/S antigens., Conclusion: The ELISA-positive results were confirmed by Western blot analysis. As a result, seroprevalence of F. hepatica infection was found in 31.4% of sheep from the Karayaka breed in the Middle Black sea region of Turkey., (Copyright © 2015. Published by Elsevier B.V.)

We investigated migratory birds' role in spreading Crimean-Congo hemorrhagic fever virus (CCHFV) through attached ticks. We detected CCHFV RNA in ticks on migratory birds in Turkey. Two isolates showed similarity with CCHFV genotype 4, suggesting a role for ticks in CCHFV epidemics in Turkey and spread of CCHFV by birds.

A coprologic study was conducted to determine the prevalence of helminth infections at the Samsun Zoo, Turkey. There are 184 animals comprising 45 species or subspecies, including 23 ruminants, three equines, 21 carnivores, 10 rabbits, two primates, two kangaroos, and 123 birds in the zoo. Fecal samples of zoo animals were collected and examined four times from 2006 to 2007: in September, December, March, and June. In four seasons, coprologic analysis revealed that 123 of 338 (36.4%) fecal samples were infected with different helminths types, including one trematode, one cestode, and 12 nematodes eggs or larvae. Species included Dicrocoelium spp. (0.9%), Moniezia spp. (1.1%), Toxascaris leonina (7.1%), Toxocara spp. (8.6%), Uncinaria stenocephala (1.4%), Dictyocaulus filaria (1.9%), Muellerius spp. (14.1%), strongyle type (20.7%), Strongylus edentatus (8.3%), Cyathostomum spp. (66.7%), Trichuris spp. (3.9%), capillarid type (9.5%), Ascaridia spp. (1.9%), and Heterakis spp. (12%).
