Investigation of toxoplasma gondii in stray dogs of Ankara province

Abstract

Bu çalışma, Ankara sokak köpeklerinde toksoplazmozisin seroprevalansını saptamak amacıyla yapılmıştır. Değişik yaş gruplarında ve melez ırktan toplam 107 sokak köpeğinden kan örneği alındı. Köpeklerin genel klinik muayeneleri yapılarak veriler kaydedildi. Serum örnekleri, Anti-Toxoplasma gondii (T. gondii) antikorları yönünden Sabin Feldman Dye Testi (SFDT) ile çalışıldı. SFDT'inde 1/16 ve üzeri titreler pozitif olarak değerlendirildi. SFDT ile T. gondii antikorları araştırılan 107 köpeğin 58'si (%54) 1/16 ve üzerindeki titrelerde seropozitif bulunurken, 49'unun (%46) seronegatif olduğu tespit edildi. Seropozitif olan 58 köpeğin antikor titreleri 16'sında 1/16, 12'sinde 1/64, 15’inde 1/256, 15'inde 1/1024 olarak saptandı. Bu veriler, Ankara'dan örneklenen sokak köpeklerinde T. gondii'nin yaygın olduğunu göstermektedir.The aim of the present study was to determine the seroprevalance of toxoplasmosis in stray dogs in Ankara. The blood samples were collected from a total of 107 stray dogs in crossbred breed and different age groups. For dogs, general physical examinations and laboratory studies were made and the data were recorded. Serum samples collected were processed by the Sabin Feldman Dye Test (SFDT) for detecting the antibodies against Anti-Toxoplasma gondii. The samples were considered as positive when the titer was 1/16 and above in SFDT. The 58 out of 107 dogs (54%) with T. gondii antibodies were seropositive while the rest (49) of all (46%) were found to be seronegative. Among the seropositive dogs (n58), the antibody titers of 16 dogs were found as 1/16 while those of the 12 dogs were found as 1/64, those of 15 dogs were found as 1/256, and finally those of 15 dogs were found as 1/1024. These results indicate that T. gondii has been widespread in stray dogs sampled in Ankara Province
