چکیده
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 types of variations in the mf1 gene but the mf3 gene in two strains was not detected by PCR. These results may have important implications in virulence factor of M. fermentans.

An easy α-glycosylation methodology for the synthesis and stereochemistry of mycoplasma α-glycolipid antigens
Mycoplasma fermentans possesses unique α-glycolipid antigens (GGPL-I and GGPL-III) at the cytoplasm membrane, which carry a phosphocholine group at the sugar primary (6-OH) position. This paper describes a practical synthetic pathway to a GGPL-I homologue (C(16:0)) and its diastereomer, in which our one-pot α-glycosylation method was effectively applied. The synthetic GGPL-I isomers were charac...
متن کاملComplexity of the Mycoplasma fermentans M64 Genome and Metabolic Essentiality and Diversity among Mycoplasmas
Recently, the genomes of two Mycoplasma fermentans strains, namely M64 and JER, have been completely sequenced. Gross comparison indicated that the genome of M64 is significantly bigger than the other strain and the difference is mainly contributed by the repetitive sequences including seven families of simple and complex transposable elements ranging from 973 to 23,778 bps. Analysis of these r...
متن کاملAntimycoplasmal activity of hydroxytyrosol.
The aim of this study was to investigate the in vitro antimycoplasmal activity of hydroxytyrosol. Twenty strains of Mycoplasma hominis, three strains of Mycoplasma fermentans, and one strain of Mycoplasma pneumoniae were used. For M. pneumoniae, M. hominis, and M. fermentans, the MICs were 0.5, 0.03 (for 90% of the strains tested), and 0.25 microg/ml, respectively.
متن کاملProteomics Characterization of Cytoplasmic and Lipid-Associated Membrane Proteins of Human Pathogen Mycoplasma fermentans M64
Mycoplasma fermentans is a potent human pathogen which has been implicated in several diseases. Notably, its lipid-associated membrane proteins (LAMPs) play a role in immunomodulation and development of infection-associated inflammatory diseases. However, the systematic protein identification of pathogenic M. fermentans has not been reported. From our recent sequencing results of M. fermentans ...

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...
