Recognition of Mycoplasma canis as part of the mycoplasmal flora of the bovine respiratory tract.
Mycoplasma strain C3b was isolated in the Netherlands from the lung of a pneumonic calf. Forty similar strains were isolated afterwards from calves in 19 other herds in different parts of the Netherlands. Eight strains from eight different herds were investigated in this study. Results of tests to determine whether the organism catabolized glucose were inconclusive. Four strains, including strain C3b, apparently catabolized glucose under some test conditions; the remaining four strains did not. Although strain C3b and similar strains were slightly different from canine M. canis strains in growth inhibition tests and glucose metabolism tests, we concluded that strain C3b and similar strains have to be classified as M. canis. A close contact between calves and dogs was observed in several herds where strain C3b or similar strains were isolated. This is the first report of M. canis isolated from cattle.
