technique, and 9 of 20 when an anaerobic jar was used). Thus, anaerobic fermentation of mannitol seems to be too exacting a criterion, but all methods using glucose fermentation classified the 20 coagulase-positive strains as staphylococci. The classification of other staphylococci into S. saprophyticus and S. lactis on their ability to produce acetoin from glucose (Shaw et al.) was not supported by the results of tests reported here. Some strains of each of these species were, in the newer tests, classified a's staphylococci and

Influence of anti-slime glycolipoprotein serum on the interaction between Pseudomonas aeruginosa and macrophages.
Glycolipoprotein, a purified fraction of the exopolysaccharide slime of Pseudomonas aeruginosa, was identified as responsible for a number of the biological activities of viable cells, including toxicity and immunogenicity capable of stimulating protective antibody against the lethal effects of viable cells. Antiserum against glycolipoprotein also mediated the phagocytosis and subsequent killin...
متن کاملAntiphagocytic Effect of Slime from a Mucoid Strain of Pseudomonas aeruginosa.
Mucoid strains of Pseudomonas aeruginosa produce a viscid slime when grown on the surface of agar media. These strains are known to colonize persistently the tracheobronchial tree of children with cystic fibrosis. Colonization may result from inhibition of phagocytosis due to slime produced by the organism. Slime separated from one mucoid strain was examined to determine whether it possessed an...
متن کاملSlime of Pseudomonas aeruginosa: in vivo production.
Indirect hemagglutination inhibition tests were employed to detect slime in concentrations as low as 1 mug/ml. Increasing concentrations of slime resulted in proportionately greater inhibition of hemagglutination. Peritoneal aspirates and plasma of mice injected with slime were shown to exhibit the inhibitory activity of slime. The rapid dissemination of slime into the peripheral circulation wa...

on slime polysaccharide A, whereas depolymerases associated with phages 6, 7, 9, and 10, like pseudomonas phage 2, hydrolyzed slime polysaccharide B. None of the depolymerases was active on slime polysaccharide C. Despite exhaustive purification, depolymerase activity was found to band with the phage particles at a density of 1.49 to 1.51 g/mI in a density gradient composed to cesium chloride. ...
متن کاملA Simple Procedure for Quantitatively Measuring Pseudomonas aeruginosa Slime Production
Pseudomonas aeruginosa is an opportunistic bacterial pathogen most associated with infection of the lungs of cystic fibrosis (CF) patients. It produces extracellular polysaccharides collectively referred to as slime that includes one specific virulence factor known as alginate. Current methods to measure the actual production of this slime require either expensive equipment, or they are not qua...
متن کاملAntibiotic resistance in Pseudomonas aeruginosa is associated with decreased fitness.
The number of clinical specimens containing β-lactam-resistant Pseudomonas aeruginosa isolates is increasing. However, whether resistance is associated with reduced fitness is still uncertain in clinical Pseudomonas aeruginosa isolates. In this study, we aimed to determine whether β-lactam resistance conferred a fitness cost in Pseudomonas aeruginosa. Growth rate, extracellular slime production...
