Almost complete (> 96%) 16S rRNA sequences from nine ruminant mycoplasmas have been determined by solid-phase DNA sequencing. Polymorphisms were found in four of the 16S rRNA sequences, which indicated the existence of two different rRNA operons. Seven polymorphisms were found in Mycoplasma agalatiae, three were found in Mycoplasma bovis, one was found in Mycoplasma alkalescens, and one was fou...

introduction: ureaplasma uriealyticum is one of the most important causes of nongonococcal and nonspecific urethritis (ngu & nsu) in men. mycoplasma hominis too has a causal role in ngu & nsu. this study aimed to investigate whether it is possible to detect mycoplasma hominis and ureaplasma uriealyticum in first voided urine samples in men suffering from ngu & nsu without complaints of urethral...

background and objectives: women reproductive system is a suitable environment for growth of various pathogen and nonpathogenic microorganisms. mycoplasmataceae is a family of bacteria which cause oligosymptomatic genital infections. the complications caused by these bacteria may lead to infertility in women. the aim of this study was detection of genital mycoplasma hominis, ureaplasmaurealytic...

Peptide deformylase inhibitor LBM-415 and seven other drugs were tested against Mycoplasma pneumoniae (100 isolates), Mycoplasma hominis (20 isolates), Mycoplasma fermentans (10 isolates), and Ureaplasma species (50 isolates). LBM-415 was active against M. pneumoniae (MICs, <or=0.008 microg/ml). It showed no activity against M. hominis and M. fermentans and modest activity against Ureaplasma spp.

We determined in vitro susceptibilities for ABT-492 and other antimicrobials against Mycoplasma pneumoniae, Mycoplasma fermentans, Mycoplasma hominis, and Ureaplasma species. ABT-492 MICs were < or =1 microg/ml, and the agent was bactericidal against selected isolates of M. pneumoniae and M. hominis. ABT-492 has potential for treatment of infections due to these microorganisms.

We isolated a Mycoplasma hominis-like mycoplasma from a stock culture of Chlamydia pneumoniae TW-183 obtained from the American Type Culture Collection and eradicated the contaminant by treating the stock suspension with a nonionic detergent, Igepal CA-630. The M. hominis-like mycoplasma neither inhibits nor enhances the infectivity of C. pneumoniae for HEp-2 cells.

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.
