Quantitative Measurement of the Growth of Pleuropneumonia-like Organisms

Quantitative measurement of the growth of pleuropneumonia-like organisms.

Accurate and reliable methods for the quantitative measurement of the growth of pleuropneumonia-like organisms have never been developed. Studies on members of this group of organisms have advanced in recent years to the stage at which further developments will be impeded by the lack of such methods. Generally techniques employed for rapid quantitation of bacterial growth, such as turbidity, pa...

Lipid requirements for the growth of pleuropneumonia-like organisms.

MIany of the pleuropneumonialike organisms (PPLO) require for growth a factor found in mammalian blood sera. This factor has been isolated and characterized as a lipoprotein (Smith et al., 1954). The protein moiety, cholesterol ester, and phospholipid, comprising this lipoprotein, are all growth requirements. Edward and Fitzgerald (1951) reported that cholesterol was active in promoting growth ...

Pleuropneumonia-Like Organisms (PPLO) Mycoplasmataceae

This small book is an attempt to review present knowledge on the morphology, immunology, and pathogenicity of the pleuropneumonia-like organisms (PPLO). The author is a recognized authority on these organisms and the material is presented from her point of view, although she readily admits that there are some who may be in disagreement with her conclusions. Four of the eleven chapters are devot...

Genital strains of human pleuropneumonia-like organisms.

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...
