1ST DIAGNOSIS OF THROMBOEMBOLIC MENINGOEN CEPHALITIS (TEME) AND ABORTION CAUSED BY HAEMOPHILUS-SOMNUS IN CATTLE

First diagnosis of thromboembolic meningoencephalitis (TEME) and abort ion has been reported in Hungary. The diseases were diagnosed in two d ifferent West-Trans-Danubian cattle stocks and were confirmed by the i solation of H. somnus. TEME was observed sporadically in 4 to 5 months old cattle collected from different places. A cow aborted a 4 month o ld embryo. In accordance with the foreign reports, the histopathologic al examinations revealed a meningoencephalitis with the formation of G ram-negative bacterium emboli and fibrin thrombi (Figs 1 to 5). Howeve r, in the lungs of aborted embryo - possible due to the young age - in flammatory-cellular reaction could not be observed. Other diseases - c oming into consideration from the point of view of differential diagno sis - were excluded by laboratory investigations. Haemolysing activity , antibiotic sensitivity and biochemical characteristics of the H. som nus strains isolated from the brain of cattle died due to TEME and fro m the gastric content of aborted embryo differed each other (Table).
