AbstractThe purpose of the study was to establish the range of T. gondii infection in farmed foxes in Poland. Serological examinations were carried out on 122 breeding foxes taken from 14 farms. Blood samples were obtained from the primary herd in the period from January to May of 1996. The serological examinations were performed using the particle latex agllutination method (Pastorex® Toxo, Sanofi Diagnostics Pasteur). Examinations for the presence of parasites were performed on impression smears of liver, spleen, lungs and brain with the use of the immunofluorescence method (Monofluokit® Toxo, Diagnostics Pasteur). Preparations were also stained with Hemacolor® (Merck) and the Giemza method. The presence of specific anti-T. gondii antibodies were found in 33.6% of the examined foxes. High titres (= 480 IU/ml) were observed in 36.59% of seropositive animals, medium titres (= 129 < 480) and low titres (= 6 < 120), in 21.95% and 41.46% respectively. Only 3 farms produced entirely negative results. These farms were approved reproductive farms with very good hygienic conditions. In the other farms the percentage of positive results was from 6.6% to 80%. In 3 farms high levels of specific antibodies in vixens which had aborted or lost their litters in the first few days after kittening were observed. The presence of the parasite was found in 2 cases using the immunofluorescence method and in 3 cases in preparations stained by Hemacolor. No forms of T. gondi were observed in preparations stained by Giemza.
