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 106 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, intramuscular, intravenous, and cloacal. The quails of the parenteral group were also divided into two groups and one by control group within itself for the 105 and 104 doses of the tachyzoite inoculums.RESULTS: Because of acute toxoplasmosis, death occurred in a quail that as intramuscularly infected with 105 tachyzoites; the quail exhibited neurological 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 105 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 105 and 104 tachyzoites.CONCLUSION: Similar studies and subclinical cases, which may overlooked was concluded for diagnosis of toxoplasmosis with useful bioassay applications and serological tests.
