Seroprevalence of equine babesiosis in the Black Sea region of Turkey

The prevalence of Theileria equi and Babesia caballi was determined in equid blood samples in five provinces of the Black Sea region of Turkey by using the indirect fluorescent antibody test (IFAT). Of 153 samples, 53 (34.6%) and 33 (21.5%) were seropositive to B. caballi and T. equi, respectively. In addition, 8 (5.2%) of samples were seropositive to both T. equi and B. caballi. Anti T. equi and B. caballi antibodies were detected in all five regions. The prevalence of B. caballi was higher than T. equi in all counties. Antibodies to T. equi and B. caballi were detected in horses of all ages, and there were no significant differences among age groups. Out of 84 horses, 32 (38.0%) were positive for B. caballi infection and 20 (23.8%) were positive for T. equi infection. Five horses (5.6%) were found to be seropositive to both B. caballi and T. equi. Of 38 donkeys, 14 (36.8%) were found to be positive for B. caballi infection and 5 (13.1%) positive for T. equi infection. In addition, 2 (5.2%) samples were seropositive for both T. equi and B. caballi infections. Out of 31 mules, 8 (25.8%) were positive for B. caballi infection and 8 (25 8%) positive for T. equi infection. One (3.2%) sample was seropositive for both T. equi and B. caballi infections. Of all the animals in this study, only 3 horses were infected by Rhipicephalus turanicus and Hyalomma detritum, and no haemoparasites were detected by microscopic examination.

Molecular identification of Anisakis species (Nematoda: Anisakidae) from marine fishes collected in Turkish waters.

Anisakid nematodes are important etiological agents for zoonotic human anisakiasis (or anisakidosis). These parasites in the Turkish waters still remain unexplored. This study aims the molecular identification of Anisakis species in Turkeys coast from Black, Aegean and Mediterranean Sea and specifically to screen for zoonotic species in commonly commercialized a total of 1145 fish belonging to 31 different species using both polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) and sequencing of the ribosomal internal transcribed spacer (ITS) regions and the mitochondrial cytochrome C oxidase subunit II (cox2) gene. A total of 776 Anisakis type I larvae were isolated in 56/1145 (4.8%) fish of 7 species from Turkish waters. The combining all of our results, e.g., morphology, PCR-RFLP, ITS region, and the cox2 gene, conclusively supported the identification of 3 Anisakis spp. taken from marine fish hosts, namely Anisakis pegreffii, Anisakis typica and Anisakis simplex sensu stricto (s.str.)/A. pegreffii hybrid genotype. No Anisakis larvae were isolated from the Black Sea whereas A. pegreffii, A. typica and A. simplex s.str./A. pegreffii hybrid genotype was found in the Aegean Sea and A. pegreffii was only isolated from the Mediterranean Sea. This study represents the first identification of A. typica and A. simplex s.str./A. pegreffii hybrid genotypes from Turkish waters. Moreover, in the present study first record of the presence of A. pegreffii is also reported from Turkish coasts of Aegean and Mediterranean Sea. No zoonotic Anisakis species were found in commonly commercialized 1025 fish belonging to 16 different species from the Black Sea, thus Turkish populations who consume captured fish from the Black Sea may have a less risk of human anisakiasis or allergies. However, the prevalence of larvae were 47.1% and 46% and recognized zoonotic A. pegreffii were identified from the Aegean and Mediterranean Sea coast, suggesting a high threat of anisakiasis or allergies for Turkish populations who consume fish originating in these regions.

Role of Migratory Birds in Spreading Crimean-Congo Hemorrhagic Fever, Turkey

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.

Abstract 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%).

Investigation of Echinococcus multilocularis in Environmental Definitive Host Feces in the Asian and the European Parts of Turkey

A study was carried out to investigate the presence of Echinococcus multilocularis in red foxes (Vulpes vulpes) in two regions of Turkey—central Anatolia (in Asia Minor) and Thrace (in the European part of Turkey). A total of 405 putative fox feces were collected from central Anatolia (186 specimens in 59 locations) and from Thrace (219 specimens in 114 locations). All samples were examined by the flotation and sieving method for taeniid eggs, and positive and putative samples were further analyzed by multiplex PCR. In seven samples from three locations in central Anatolia (5.1%) and in one (0.9%) from Thrace, E. multilocularis DNA was amplified, and this result was confirmed with another PCR specific for E. multilocularis. In addition, Echinococcus granulosus s.l. was found in two (0.5%) of the samples. Although alveolar echinococcosis (AE) is known as a serious zoonosis in Turkey, this is the first field study detecting E. multilocularis in collected fecal samples documenting the environmental contamination with eggs of this zoonotic parasite.

A case of auricular, anal and umbilical myiasis caused by the larvae of Phormia regina (Meigen) (Diptera: Calliphoridae) in neonatal kittens.

The occurrence of feline myiasis is rare. Massive infestations of dipteran larvae can lead to death if not treated at an early stage. Auricular, anal and umbilical myiasis was detected in three neonatal kittens. The dipteran larvae were collected, fixed in 70% alcohol and clarified with 10% KOH for a few days. Later, larvae were dissected under the stereomicroscope, mounted on slides and then identified as the third instar of the black blowfly, Phormia regina (Meigen) (Diptera: Calliphoridae), according to their stigmatic and cephaloskeleton structures. Original measurements and figures are presented. Treatment included mechanical removal of larvae and cleansing of the area by applying polyvinylpyrrolidone-iodine complex. The presence of P. regina in cats has been reported here for the first time in Turkey.

[Helminths of pheasant (Phasianus colchicus) detected by necropsy and faecal examination in Samsun, Turkey].

OBJECTIVE This study was performed at the Gelemen Pheasant Procreation Farm affiliated to the General Directorate of Nature Conservation and National Parks, Ministry of Forest and Water Affairs. METHODS A total of 203 faecal samples and 17 necropsies were examined. RESULTS In the faecal examination, Capillaria spp. accounted for 28.6% and Heterakis spp. for 17.2% of eggs; in necropsy, Capillaria annulata (17.6%), C. bursata (35.3%), C. caudinflata (23.5%), C. contorta (64.7%), C. obsignata (5.9%) and Heterakis gallinarum (58.8%) were detected. DISCUSSION Syngamus trachea, often reported in helminths in pheasant, could be found neither upon faecal examination nor on necropsy. CONCLUSION This study is the first extensive research to identify helminths of pheasants in Turkey. Capillaria bursata, C. caudinflata, C. contorta, C. obsignata and H. gallinarum are the first reports from pheasants in Turkey.
