Electron microscope studies of pleuropneumonia like organisms isolated from man and chickens.
The characteristic colony morphology is an important distinguishing feature which is used for recognizing members of the group of pleuropneumonia-like organisms. However, characteristic colony morphology may not be apparent when the organisms are freshly isolated from the body or when the growth is crowded on the surface of solid medium. In order to determine similarities or differences among t...
متن کاملComparison of lipid composition of pleuropneumonia-like and L-type organisms.
Smith, Paul F. (University of Pennsylvania, Philadelphia) and George H. Rothblat. Comparison of pleuropneumonia-like and L-type organisms. J. Bacteriol. 83:500-506. 1962.-The content of total lipid and nonsaponifiable lipid depended upon the type of organism; the greatest amounts were found in pleuropneumonia-like organisms that required cholesterol for growth and in L-1, the L-form of Streptob...
متن کاملThe growth of pleuropneumonia-like organisms of human origin: cultivation in the developing chick embryo and an in vitro growth cycle.
Some strains of pleuropneumonia-like organisms (PPLO) of human origin grow quite sparingly in vitro; therefore, attempts were made to determine if these organisms could be sustained better in the developing chick embryo. A semiquantitative comparison of growth on artificial media and in the chick embryo is presented. As pleuropneumonia-like organisms aIe frequent inhabitants of the genitourinar...
متن کاملElectron 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...
متن کاملMetabolic 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), ...
