T-Form colonies of pleuropneumonialike organisms.
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...
متن کاملReduction of tetrazolium salts by pleuropneumonialike organisms.
Tetrazolium salts have proved useful as indicators of electron transfer. Compounds such as triphenyltetrazolium chloride' are more practical than indicators like methylene blue since they are converted from a soluble colorless salt to an insoluble formazan in the reduced state. They also provide similar convenience in detecting enzymatic activity and specific sites of such activity (Bielig, Kau...
متن کاملRegulation of neutral cholesterol esterase activity
The effect of phospholipids on cholesteryl ester hydrolysis by neutral cholesterol esterase in alveolar macrophages was studied. Among the phospholipids used as emulsifiers, those with a negative charge, such as phosphatidylserine, phosphatidic acid, phosphatidylinositol, and cardiolipin, gave a higher level of hydrolysis by neutral cholesterol esterase than other less negatively charged phosph...
متن کاملAmino acid metabolism by pleuropneumonialike organisms. II. Glutamine.
A previous examination of the over-all catabolic activity of certain strains of pleuropneumonialike organisms of human origin toward amino acids demonstrated that only glutamine and arginine were readily degraded (Smith, 1955a). L-Glutamine was completely converted to glutamic acid by some mechanism of deamidation. Levintow and Meister (1954) reported on the ability of a purified pea enzyme, ca...
متن کاملIntestinal cholesterol esterase: intracellular enzyme
The location of cholesterol esterase in rabbit intestine was re-evaluated. In three different experiments that were designed to eliminate contaminating mucus and pancreatic enzymes from the lumen of the small intestine, it was observed that the activities of cholesterol esterase and amylase in intestinal cytosol and whole homogenate decreased in parallel fashion. After the mucus was carefully w...
