Objective: Toxoplasmosis, in which obligate intracellular protozoa Toxoplasma gondii (T.gondii) is the causative organism, is a multisystemic disease that can be seen all over the world and can impair all vertebrates. The only hosts known for T.gondii are members of Felidae family. Our study aimed to determine anti-Toxoplasma gondii antibodies with Sabin-Feldman Dye Test (SFDT) in cats in Ankara. It's aimed to evaluate the current situation in terms of Toxoplasmosis spread by comparing our findings with previous studies in the same region. Methods: Rh strain of Toxoplasma used in our study is maintained in our laboratory. SFDT is still accepted as the gold standard. Material of the study was obtained by taking blood samples from cats who were admitted to the clinics between March 2016 and October 2016 in Ankara. Blood samples were inactivated and measurements were done with SFDT 1/4, 1/16, 1/64, 1/256, 1/1024 titers. Results: SFDT resulted positive in 56 (43.4%) cats at a dilution of 1/16, in 7 (5.4%) cats at a dilution of 1/64, in 23 (17.8%) cats at a dilution of 1/256 and negative in 43 (33.3%) cats. Comparison of demographic data with SFDT results showed that positive test results did not differ according to gender and age (P=0.803 and P=0.991, respectively). Seropositivity was higher in stray cats Amaç: Toksoplasmozis, zorunlu hücre içi protozoon olan Toxoplasma gondii'nin (T.gondii) etken olduğu, tüm dünyada yaygın görülebilen ve tüm vertebralıları tutabilen multisistemik bir hastalıktır. T. gondii için bilinen tek kesin konak Felidae ailesinin üyeleridir. Çalışmamızda Ankara'da kedilerde Sabin-Feldman Dye Testi (SFDT) ile anti-Toxoplasma gondii antikorlarının tespiti amaçlanmıştır. Aynı bölgede daha önceden yapılan çalışmalar ile karşılaştırmalar yapılarak Toxoplasmozun yayılımı açısından günümüzdeki durumun değerlendirilmesi hedeflenmiştir. Yöntemler: Çalışmamızda kullanılan Toxoplasma Rh suşunun idamesi laboratuvarımızda sağlanmaktadır. T.gondii tanımlanmasında kullanılan SFDT serolojik bir testtir ve altın standart olarak kabul edilmektedir. Çalışmanın materyali Mart 2016-Ekim 2016 tarihleri arasında Ankara'da kliniklere müracaat eden kedilerden kan örnekleri alınarak sağlanmıştır. Kedilerden alınan kan örnekleri inaktive edilerek SFDT 1/4, 1/16, 1/64, 1/256, 1/1024 titrelerde çalışılmıştır. Bulgular: Toxoplasma gondii araştırması yapılan kedilerin 56'sında (%43,4) SFDT 1/16 titrede, 7'sinde (%5,4) 1/64 titrede, 23'ünde (%17,8) 1/256 titrede pozitif saptanırken, 43'ünde (%33,3) negatif çıkmıştır. Demografik bilgiler ile SFDT sonuçlarının karşılaştırılmasında; pozitif test sonuçlarının cinsiyet ve yaş ile ilişki göstermediği bulunmuştur (Sırasıyla P=0,803 ve P=0,991). Sokak kedilerinde ev kedilerine göre seropozitiflik fazladır (P<0,001). Sadece ticari kuru mama ile beslenen kedilerde test sonuçları negatiftir (P<0,001). Avlanan kedilerde pozitiflik avlanmayanlara göre fazladır (P<0,001). Sonuç: Bu çalışma ile kedilerin %66,6'sında seropozitiflik tespit edilmiştir ki halen oldukça yüksek bir orandır. Sonu...
Objective: European hares (Lepus europaeus) are among the most important animals that are connected with humans in many countries and natural life. Hares are important for public health, since they carry many zoonotic diseases, such as Encephalitozoon cuniculi, Francisella tularensis and Toxoplasma gondii. The study aimed to determine the seroprevalence of Encephalitozoon cuniculi, Francisella tularensis and T. gondii and the potential zoonotic risk posed by hares that live in provinces of Turkey.Methods: Blood samples were collected from hares during the official hunting season. Serum samples were examined serologically by enzyme-linked immunosorbent assay for E. cuniculi, Sabin-Feldman dye test was used to examine T. gondii, while micro-agglutination test was used to examine F. tularensis. Results:Of the total of 42 hares examined, one (2.4%) was found positive for E. cuniculi, two (4.8%) were found positive for T. gondii and one (2.4%) was found positive for F. tularensis. Conclusion:Anti-T. gondii and anti-E. cuniculi antibodies were serologically detected in hares for the first time in Turkey. Furthermore, this is the first study reporting the seropositivity of F. tularensis infection in hares.
Encephalitozoon cuniculi can cause latent disease, especially in lagomorphs and many wild and domestic animals in various countries. This infection is important for veterinary and public health because it is caused by a potentially zoonotic and opportunistic pathogen. The aim of this study was to investigate the relationship between seropositivity of E. cuniculi and renal function markers, which may be useful in predicting the disease in clinically healthy rabbits. In this study, the seropositivity of E. cuniculi infection in clinically healthy rabbits was determined, and necropsy findings were evaluated along with the results of renal function tests. In a laboratory rabbit breeding facility, enzyme-linked immunosorbent assay (ELISA) tests showed that 48 (49.5%) of 97 rabbits were seropositive against E. cuniculi. Blood urea nitrogen (BUN) and creatinine levels were significantly elevated in seropositive animals. Two seropositive rabbits were necropsied to confirm the infection. According to histopathological findings in the kidney, degenerative changes and E. cuniculi spores were identified in the tubule epithelia. Serum creatinine (p<0.001) and BUN (p<0.01) levels were found to have a statistically significant relationship with the serological status of rabbits. Serological and histopathological methods are not routinely used in rabbits to diagnose E. cuniculi infection. The kidneys were one of the most affected organs in encephalitozoonosis in rabbits. As revealed in this study, the testing blood urea nitrogen and creatinine levels would be useful for the evaluation of general health status and renal function of the seropositive rabbits, and clinical interpretation as well.
