“…The early detection of antibodies at 1 wpi is probably due to the introduction of tachyzoites parenterally. Sedlák et al (2000) detected antibodies at 2 wpi after oral infection of chickens with 10 5 oocysts. Earlier, Kaneto et al (1997) stated that chickens inoculated orally with T. gondii oocysts developed IFAT antibodies, but did not provide quantitative data.…”

Toxoplasma gondii infections in free-range (FR) chickens (Gallus domesticus) are potential public health risks. Antibodies for T. gondii were found in 194 out of 303 serum samples (64.03%) from FR chickens in Thailand tested by the indirect fluorescent antibody test (IFAT, 1:16). To verify the validity of serologic data in this survey, sera from chickens experimentally infected with the RH strain of T. gondii were tested by the IFAT. Antibodies against T. gondii were detected as early as 7 days p.i., peaked at 2 weeks, and then declined by 10 weeks p.i.

“…In this study, both IFAT and MAT were used and able to detect T. gondii antibodies in all inoculated chickens. IFAT 7 T. gondii tachyzoites (RH strain) injected muscularly [14], or fed with 10 3 or 10 5 T. gondii oocysts K7 (avirulent) strains [29]. Similarly, after chickens was fed with 10 3 or 10 5 of ME49 oocysts, MAT was able to detect antibody at 1:100 serum dilutions at day 15 post-inoculation [30].…”

Toxoplasma seroprevalence in free-range chicken, which directly feed from ground, is a good indicator for detecting an environment contamination by T. gondii oocysts. Many serological methods have been used for diagnosing Toxoplasma infection in animals including chicken. Selection of appropriate methods primarily depend on their sensitivity and specifi city as well as laboratory techniques, special reagent or tool requirements and regional prevalence status. The aims of this study were to determine the prevalence of T. gondii antibody in free-range chickens in Thailand and to compare two serodiagnostic methods, indirect fl uorescent antibody test (IFAT) and Modifi ed Agglutination Test (MAT). Six hundred free-range chicken sera were collected from 2 villages in Kanchanaburi Province, Thailand, 300 in 2014 and 300 in 2015. The age of chickens was between 3-6 mo, of which chickens of 2015 were older than of 2014. Collected sera were test for T. gondii IgG antibody by both methods. Over all Toxoplasma seroprevalence were 33.0% and 17.7% by IFAT and MAT, respectively. There was poor agreement between the two serological methods (kappa=0.09). IFAT in this study revealed higher positive percentage than MAT. Even though the way of living and environment in the present study was suitable for Toxoplasma transmission, the seroprevalence in Thai free-range chickens was low compared to other tropical regions such as Africa or South America. A low Toxoplasma prevalence was also found in humans, cats and other intermediate hosts in Thailand. Toxoplasmosis in Thailand causes low burden compare to other infectious diseases, however, consume well-cooked free-range chicken meat and proper practice during handling raw meat when cooking should be advocated to prevent and reduce this infection.

“…The second study was conducted on gallinaceous game birds (Sedlak et al 2000b). Partridges (Perdix perdix), chukars (Alectoris chukar), wild guineafowl (Numida meleagris) and wild turkeys (Meleagris gallopavo) were inoculated per os with two doses of T. gondii oocysts.…”
