| Popis: | The lungs of 139 calves presented for autopsy and 29 healthy slaughtered calves were examined for Legionella by culture and by direct immunofluorescence (DIF) with fluorescein-conjugated antisera. About 17% of the cadaver lungs and 4% of lungs from slaughtered animals were positive by DIF. Legionella organisms were only isolated from the lungs of two cadavers ( L. pneumophila , serogroup 1). In a prevalence study of antibodies to Legionella in domestic and wild animals of various species, titers of ⩾64 were demonstrated by indirect immunofluorescence in sera of 10% of dairy cattle, 5% of beef cattle, 4% of sheep, 22% of antelopes, 35% of horses, 36% of buffaloes and 0% of laboratory rabbits. The isolation of Legionella from lung tissue is evidence for a possible etiologic role of Legionella spp. in natural pathology of animals. |
