[Identification of mycoplasmas isolated from monkeys]

The authors identified 15 strains of mycoplasmae isolated from Papio hamadryas suffering from leukemia and from healthy Macacus rhesus, a green monkey and saimiri. A study was made of their biochemical properties, antigenic properties in the reaction of growth depression with immune sera to a number of standard strains, and also the protein composition by electrophoresis in polyacrylamide gel (EPAG). A number of mycoplasmae were identified as A. laidlawii, M. arthritidis--Campo and M. cynomolgus KI, affilated to M. orale II. Four strains were apparently a mixture of three mycoplasmae (M. cynomolgus KI, M. arthritidis--Campo, and M. hyorhinis). Six strains of mycoplasmae (three enzymatically active, belonging according to EPAG data to a single serological type, and three--enzymatically inert, differing by EPAG) could not be identified.
