Direct isolation of mycoplasmas and acholeplasmas from sera and kidneys of calves.
Kidneys and sera of calves from various farms and primary kidney tissue cultures were tested for mycoplasma and acholeplasma contamination. Altogether 24 strains belonging to Mycoplasma arginini and Acholeplasma axanthum were isolated from tissue cultures, kidneys and sera. The same species were detected from lungs and peribronchial lymph nodes of calves, together with A. laidlawii, A. modicum and M. bovirhinis species. There was a close correlation between the mycoplasma content of tissue cultures, sera and kidneys and the clinical picture observed in the farm, as well as between the quality of tissue cultures and the mycoplasma content of organs, sera and tissue cultures.
