| Abstract: | Serum samples of 113 dogs visiting "outpatient clinics", 52 dogs kept in shelters and 35 animals from a military dog training centre were examined for Toxoplasma gondii specific antibodies using a latex agglutination test. Significant differences in seroprevalences were found between dogs from the training centre (8.6% of positive results) and the other populations examined (40.7% of positive seroreagents in animals visiting outpatient clinics and 44.2% in the group from shelters, respectively). Among clinic patients, dogs fed raw meat were significantly more frequently seropositive (65.2%) than those eating only commercial dry feed or cooked meat (25.7%). No statistically significant differences were noted in males compared to females and in pure breed dogs compared to crossbreed dogs. The antibodies were usually found in low titres under 60 IU/ml (69.6% of positive results). High titres (120-480 IU/ml) were detected in 2 of 3 dogs with clinical toxoplasmosis. In these dogs IFAT T. gondii specific IgM were detected and a favourable response to antiprotozoal treatment was observed. All the dogs with medium and high titres were given raw meat. Age and the presence of cats did not seem to have any influence on T. gondii seroprevalence. Neospora caninum specific antibodies in low titres ranging from 1:20-1:320 were found in 7 (9.7%) of 72 T. gondii positive seroreagents. |
