Ovine Toxoplasmosis in Sweden

Toxoplasmas hos får i Sverige

Abstract

Sera from 155 ewes representing 21 different sheep flocks from the central parts of Sweden were examined for the presence of antibodies to Toxoplasma gondii by the indirect fluorescent-antibody test. Seropositive animals were found in 14 flocks, which corresponded to 55 % of the tested sera. Animals from the same flock were with few exceptions either all positive or all negative. Some ewes with a history of abortion a few months before blood sampling showed high titers indicating causative correlation with toxoplasmosis. These are the first verified cases of ovine toxoplasmal abortions in Sweden.

Sammanfattning

Sera från 155 tackor från 21 olika fårbesättningar i Mellansverige och på Gotland har undersökts med indirekt immunofluorescensteknik avseende förekomst av antikroppar mot Toxoplasma gondii. Seroposi-tiva djur hittades i 14 besättningar, vilket motsvarar 55 % av de under-sökta djuren. Undersökta tackor från samma besättning var med få undantag antingen alla positiva eller alla negativa. Några av tackorna som tidigare under året aborterat visade höga titrar mot Toxoplasma. Dessa aborter har uppenbarligen orsakats av toxoplasmas, som tidigare inte fastställts som abortorsak hos får i Sverige.
