Abstract
The incidence of M. dispar, Ureaplasma and conventional (large colony) mycoplasma, isolated from the pneumonic lungs of groups of young calves, and the identification to species level of mycoplasmas in mixed populations with the aid of the indirect fluorescent antibody test are described. Pneumonic lung tissue yielded 1 or more mycoplasma species from 88% of the 153 calves cultured. The mycoplasmas identified and percent of the calves with lungs positive for each species were: M. dispar (56%), Ureaplasma (44%), M. bovis (37%), M. arginini (33%) and M. bovirhinis (23%). Conventional mycoplasmas isolated from 2 calves (1%) could not be identified using the antisera available.
