Abstract: | Seventy bovine mycoplasma strains recovered from cases of calf pneumonia, and all displaying the cultural characteristics of Mycoplasma dispar, were compared to the type strain of this species by the disc growth inhibition test, the metabolism inhibition test and indirect epi-immunofluorescence test applied to colonies on agar. Sixty-seven strains were found to be identical with M. dispar. The remaining three strains formed a distinct serogroup partially separate from the type strain of M. dispar, but the difference from the type strain was not considered great enough to warrant the establishment of a subspecies. |
