    Investigation of the Prevalence of Fasciola hepatica in Small Ruminants in the Siirt Region, Turkey
    (Iranian Scientific Society Medical Entomology, 2018) Celik, Ozgur Yasar; Aslan Celik, Burcak
    Background: Fasciolosis is a disease of the liver caused by trematodes in the family of Fasciolidae, particularly by Fasciola hepatica and Fasciola gigantica. The aim of this study was to investigate the prevalence of F. hepatica in sheep using the ELISA method, and in hair goats by post-mortem liver examination in the Siirt region, Turkey. Methods: This study was conducted between Feb-Sep 2018. Five ml of blood samples were taken from the jugular veins of 320 sheep, which were selected from various locations of Siirt region by random sampling method. Fasciolosis seroprevalence in sheep was investigated by the ELISA method, using commercial kits (BIOK 211-Monoscreen AB ELISA F. hepatica test). In order to determine the prevalence of fasciolosis in hair goats, 580 slaughtered goats were examined for F. hepatica by incisions in the liver, gallbladder, and bile ducts. Results: While 24 (7.50%) sheep were seropositive, 296 (92.50%) were seronegative. Regarding the hair goats, on the other hand, 82 (14.14%) were positive, while 498 (85.86%) were negative. Conclusion: F. hepatica infection causes significant economic losses due to the destruction of the liver in small ruminants. Considering zoonotic properties of the disease, it has been concluded that the necessary measures should be taken and anti-helminthic drugs should be applied to the animals that come out of the pasture. Furthermore, periodic examinations should be conducted, and the breeders should be informed about the disease to raise awareness.

    Preliminary investigation of the prevalence and genotype distribution of Cryptosporidium spp., and Giardia duodenalis in cats in Siirt, Turkey
    (Sciendo, 2023) Aslan Celik, Burcak; Celik, Ozgur Yasar; Ayan, Adnan; Akyildiz, Gurkan; Orunc Kilinc, Ozlem; Oktay Ayan, Ozge; Ercan, Kerem
    Cryptosporidium spp. and Giardia duodenalis are protozoan parasites found in humans and many animal species worldwide. The aim of this study was to determine the prevalence and genotypes of Cryptosporidium spp. and Giardia duodenalis in cats and to evaluate the zoonotic potential of these agents. The animal material of the study consisted of a total of 40 cats brought to the Veterinary Faculty. Fresh fecal samples taken from the cats were placed in individual sample containers. All samples were examined under the microscope by Kinyoun Acid Fast staining for Cryptosporidium spp. and by the native-Lugol method for Giardia duodenalis. Nested PCR and sequence analyses were then performed. As a result of microscopic and nested PCR analyses for Cryptosporidium spp., no positivity was found in any sample. The prevalence of Giardia duodenalis was 2.5% in both microscopic examination and nested PCR analyses. When the DNA sequences of the beta-Giardin gene obtained in the study were compared with the database in NCBI Basic Local Alignment Search Tool, it was determined that one sample overlapped with Assemblage B samples. As a result of this study, the prevalence of Cryptosporidium spp. and Giardia duodenalis in cats was determined and the presence of Assemblage B was revealed. It is recommended that repetitive studies should be carried out as much as possible to determine the possible role of these parasites in the transmission of these parasites to humans.
