Variation of genes encoding GGPLs syntheses among Mycoplasma fermentans strains.
The information of the biosynthesis pathways of Mycoplasma fermentans specific major lipid-antigen, named glycoglycerophospholipids (GGPLs), is expected to be some of help to understand the virulence of M. fermentans. We examined primary structure of cholinephosphotransferase (mf1) and glucosyltransferase (mf3) genes, which engage GGPL-I and GGPL-III synthesis, in 20 strains, and found four typ...
متن کاملBiochemical diversity of Mycoplasma fermentans strains.
In this study, the metabolism of a diverse range of Mycoplasma fermentans strains was investigated. It was shown that the ability to utilise glucose, fructose and N-acetylglucosamine differentiated strains, and that the patterns and kinetics of substrate utilisation were correlated with the site of isolation, i.e. joint fluid, respiratory tract, urinary tract or cell culture. Interestingly, iso...
متن کاملThe phosphocholine motif in membranes of Mycoplasma fermentans strains.
Mycoplasma fermentans strains differ in the profile of choline-containing phosphoglycolipids (PGL) present in their cell membrane. MfGL-II [Zähringer et al. (1997) J. Biol. Chem. 272, 26262-26270] was found to be the major PGL in most strains tested. However, in the pulmonary isolates, M52 and M39 the major choline-containing PGLs were MfGL-I [Matsuda et al. (1994) J. Biol. Chem. 269, 33123-331...
متن کاملCharacterization of DNA topoisomerase activity in two strains of Mycoplasma fermentans and in Mycoplasma pirum.
DNA topoisomerases (topos) are essential enzymes that participate in many cellular processes involving DNA. The presence of the DNA-gyrase genes in various mycoplasmas has been reported elsewhere. However, the characterization of DNA topo activity in mycoplasmas has not been previously undertaken. In this study, we characterized the topo activity in extracts of Mycoplasma fermentans K7 and inco...
متن کاملHeterogeneity among strains of Mycoplasma granularum and identification of Mycoplasma hyosynoviae, sp. n.
Twelve filtrable, pleomorphic organisms isolated from swine joints and respiratory tracts had typical colonial and microscopic characteristics of mycoplasmas. They resisted penicillin and did not revert to cell wall-producing bacterial forms in media devoid of bacterial inhibitors. The morphological and growth characteristics of these mycoplasmas were similar to those described previously for M...
