Abstract

Objective: In this study, forming of experimental toxoplasmosis in quails; clinical, pathological, and serological determination of tissue lesions and bioassay techniques, which were aimed to compare them and determine pathogenesis. Methods: A total of 120 one-year-old female quails (Coturnix coturnix japonica) were divided into oral infection, parenteral infection, and control groups. The oral group was infected with 0.5 ml inoculum suspension containing 10 6 tachyzoites of Toxoplasma gondii, whereas the control group was administered 0.5 ml of saline. The parenteral group was further divided into the following four subgroups: intraperitoneal, intramus- cular, intravenous, and cloacal. The quails of the parenteral group were also divided into two groups and one by control group within itself for the 10 5 and 10 4 doses of the tachyzoite inoculums. Results: Because of acute toxoplasmosis, death occurred in a quail that as intramuscularly infected with 10 5 tachyzoites; the quail exhibited neu- rological clinical symptoms such as torticollis, ataxia, and tremor. In histopathologic examination, T. gondii tissue cysts were detected in infected quails that were intramuscularly infected with 10 5 tachyzoites. Mouse trials were conducted using tissues of seropositive quails and isolated from peritoneal fluids infected mice. By Sabin-Feldman dye test and indirect hemagglutination test, seropositivity was observed in quails infected with 10 5 and 10 4 tachyzoites. Conclusion: Similar studies and subclinical cases, which may overlooked was concluded for diagnosis of toxoplasmosis with useful bioassay applications and serological tests.

Özet

Amaç: Bu çalışmada, bıldırcınlarda deneysel toksoplazmozis oluşturulması; klinik, patolojik, serolojik ve bioassay tekniklerle doku lezyonlarının,karşılaştırılması ve patogenezin belirlenmesi amaçlanmıştır.Yöntemler: Bu amaçla, 1 yaşında 120 adet dişi Japon bıldırcını (Coturnix coturnix japonica) oral, parenteral yollarla ve aynı zamanda onlarınkontrol grupları olarak gruplandırılmışlardır. Oral gruba 0,5 ml’sinde 10 6 takizoit içeren inokulum verilirken bunun kontrol grubuna 0,5 ml serumfizyolojik verilmiştir. Parenteral grup İntraperitoneal (İP), İntramuskuler (İM), İntravenöz (İV) ve Kloakal (K) olarak dört gruba ayrılmıştır. Her bir pa-renteral yol da 0,5 ml’sinde 10 4 ve 10 5 takizoit içeren inokulum verilmesi için kendi içerisinde iki gruba ve birer kontrol grubuna ayrılmıştır.Bulgular: İntramuskuler 10 5 takizoit verilen grupta bir bıldırcında akut toksoplazmozise bağlı tortikollis, ataksi ve tremor gibi sinirsel klinik belir-tileri takiben ölüm şekillenmiştir. Bu bıldırcının histopatolojisinde Toxoplasma gondii doku kistleri gözlenmiştir. Seropozitif bıldırcınlardan alınandoku örnekleri ile bioassay testleri yapılmıştır ve testlerde kullanılan farelerin periton sıvısında parazit takizoitleri izole edilmiştir. Sabin-FeldmanDye Test ve İndirekt Hemaglutinasyon ile 10 4 ve 10 5 takizoit gruplarında seropozitiflik belirlenmiştir.Sonuç: Yapılacak benzer çalışmalarda ve gözden kaçabilecek subklinik vakalarda toksoplazmozisin tanısı için serolojik testler ile bioassay uygu-lamalarının birlikte yapılmasının yararlı olacağı kanaatine varılmıştır.
