Electron Micrograph Studies of Two Strains of Pleuropneumonia-like (L) Organisms of Human Derivation

Electron Micrograph Studies of Two Strains of Pleuropneumonia-like (L) Organisms of Human Derivation.

Electron micrographs made from L forms of Proteus and two human strains of pleuropneumonia-like organisms.

The organisms in the cultures of the pleuropneumonia group and of the L forms of bacteria are visible with the light microscope. Their morphology has remained controversial for a long time because they are easily deformed in microscopic preparations and give riise to bizarre forms. It seems well established at present (Klieneberger and Smiles, 1942; Dienes, 1945) that the cultures, with a few e...

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...

Metabolic studies on three strains of Pleuropneumonia-like organisms isolated from man.

The peculiar type of growth common to Asterococcus mycoides (Pleuropneumonia bouum), pleuropneumonia-like organisms (PPLO), and L forms of bacteria has lead to confusion and controversy. This controversy involves the interrelationships of these groups and of strains within the groups as well as their relation to bacteria in general. Excellent reviews by Sabin (1941), Elleneberger-Nobel (1951), ...
