dna analysis for phospholipase a2 coding sequences of mycoplasma hominis isolated from women with a normal pregnancy and women with a pregnancy complicated by preterm labour.a possible cause of preterm labour is an increased synthesis of prostaglandins by a phospholipase a2 (pla2) activity. pla2 activity has been detected in mycoplasma hominis. the aim of this study was to test whether chromosomal dna of m. hominis contains sequences coding for pla2. m. hominis was cultured in specimens from 5 women with normal pregnancy and 4 in preterm labour. using sequence alignment, primer pairs for the active part of pla2 of different species were designed for pcr analysis. no ...19989789649
cloning and expression of p60, a conserved surface-localized protein of mycoplasma hominis, in escherichia coli.the clp60 gene encoding p60, a conserved lipoprotein of mycoplasma hominis, was cloned and sequenced from both the type strain pg21 and the isolate fbg. both open reading frames were identical in length, comprising 1746 nucleotides. the deduced amino acid sequences differed in 16 out of 582 amino acids. as expected, none of these divergences mapped within the epitope that was recognized by mab cg4 in all of the 198 isolates of m. hominis analyzed so far. this conserved epitope was narrowed down ...19989792448
genital mycoplasmas stimulate tumor necrosis factor-alpha and inducible nitric oxide synthase production from a murine macrophage cell line.ureaplasma urealyticum and mycoplasma hominis, two genital mycoplasmas, are the most common organisms isolated in the perinatal period and both either cause or are associated with poor perinatal outcomes. we speculate that these microbes could increase inflammation by stimulating macrophages to produce tumor necrosis factor-alpha (tnf-alpha) and inducible nitric oxide synthase because of their propensity to interact with the host's immune system. to test this hypothesis, raw 264.7 cells, a murin ...19989803463
exogenous bovine surfactant suppresses tumor necrosis factor-alpha release by murine macrophages stimulated by genital mycoplasmas.tumor necrosis factor-alpha (tnf-alpha) is a proinflammatory cytokine that appears to play a significant role in the development of neonatal chronic lung disease (cld). inflammation and cld are also associated with respiratory tract colonization with genital mycoplasmas. the possible protective roles of surfactant in mitigating the inflammatory response to these microbes were investigated. murine raw 264.7 macrophages were preincubated with an exogenous surfactant and exposed overnight to steril ...19989806043
