Serologic survey for toxoplasmosis in domestic birds from the Czech Republic.

The present study was carried out on domestic fowls in the Czech Republic in the years 2003 and 2004. A total of 1108 samples obtained from 538 water birds (geese and ducks) and 570 gallinaceous birds (chickens and turkeys) were tested for specific antibodies against Toxoplasma gondii using the indirect fluorescent antibody test. In geese, 43% prevalence (77 positive out of 178 examined) was found with titres of 40, 320 and 2560 in 40, 29 and eight geese, respectively. In ducks, 14% prevalence (52 out of 360) was found with titres of 40 and 320 in 46 and six ducks, respectively. In gallinaceous birds, only one of 293 broiler chickens was positive with a titre of 40; sera of 217 hens and 60 turkeys were negative. We found extremely high antibody prevalence in geese and ducks compared with gallinaceous birds. This is the first seroprevalence study in domestic birds by indirect fluorescent antibody test in Europe.
