Recently a study was unidertaken to ascertain the bacterial flora of the male urethra and the relationship of Trichomonas vaginalis and pleuropneumonia-like organisms (PPLO) in male patients with chronic urethritis. The PPLO encountered in this study differed from those described in the literature in that they could not be isolated on PPLO agar (Difco) supplemented with PPLO serum fraction A. I...

During the course of previous studies on pleuropneuimonialike organisms (PPLO) and their possible role in the etiology of nongonococcal urethritis (NGU), a minute, morphologically distinct PPLO colony form was observed (Shepard, 1954.) More recent studies have substantiated this observation. These minute colonies of pleuropneumonialike organisms were designated T-form (tiny) PPLO colonies. They...

Klieneberger-Nobel (1961) reviewed in detail the significance of large-colony pleuropneumonia-like organisms (PPLO) in the human genital tract. Unfortunately, at that time, the existence of T-strain PPLO, as described by Shepard (1956), was under dispute. Subsequently, however, Shephard's observation that T-strain PPLO could be isolated from the majority of patients with non-gonococcal urethrit...

mycoplasma contaminants can be considered important not only for their roles as pathogens but also they may indicate that insufficient care has been taken during vaccine manufacture or quality control. the purpose of this study was to test the poliomyelitis vaccines for mycoplasma by culture and polymerase chain reaction (pcr) methods. during 2008 to 2009, a total of 47 lots of oral poliomyelit...

Since the first report of Dienes and Edsall (1937), a number of communications have recorded the isolation of pleuropneumonia-like organisms (PPLO) from the genital tract of the human female, especially in association with inflammatory diseases such as bartholinitis, pelvic abscess, and salpingitis (Melen and Odeblad, 195 1; Randall, Stein, and Ayres, 1950; Dienes, Ropes, Smith, Madoff, and Bau...

Shklair, I. L. (U. S. Naval Training Center, Great Lakes, Ill.), M. A. Mazzarella, R. R. Gutekunst, and E. M. Kiggins. Isolation and incidence of pleuropneumonia-like organisms from the human oral cavity. J. Bacteriol. 83:785-788. 1962.-Pleuropneumonia-like organisms (PPLO) were isolated from the oral cavity of 87.2% (184 of 211) of young male naval recruits, by use of an enriched medium under ...

Powelson, Dorothy M. (Stanford Research Institute, Menlo Park, Calif.). Metabolism of animal cells infected with mycoplasma. J. Bacteriol. 82:288-297. 1961.-The effect of pleuropneumonia-like organisms (PPLO) upon the metabolism of tissue cultures was tested by comparing the assimilation and accumulation of the amino acids in the medium during growth and maintenance of monolayers of mouse fibro...

Pleuropneumoma-like organisms (PPLO) of the catarrhal type were isolated from the brain of a Swiss mouse during the cranial passage of mouse hepatitis virus-MHV(C). Cranial injection of the PPLO alone in Swiss and Princeton weanlings was attended by a meagre growth of the organisms in the brain, with no pathologic change. The growth of both catarrhal and conjunctival strains of PPLO in the brai...
