Polyamine profiles of 26 type strains of Gram-positive, catalase-positive cocci, belonging to different phylogenetic lineages were obtained by gradient high performance liquid chromatography (HPLC) and fluorescence detection. Clearly, growth conditions affected the total amount of polyamines, but did nor ...
It is a motile, gram-positive, facultative anaerobe. en.wikipedia.org Gram-positive bacteria regulate autolysins with teichoic acid molecules attached to the tetrapeptide of the peptidoglycan matrix. en.wikipedia.org The bacterium is a gram-positive, catalase negative, coccus growing in clusters. ...
catalase positive species to identify the coagulase positive Staphylococcus aureus. Coagulase is a virulence factor of S. aureus. The formation of clot around an infection caused by this bacteria likely protects it from phagocytosis. This test differentiates Staphylococcus aureus from other coagulase ...
S, sensitive; R, resistant; −, negative; +, positive. Streptococci The streptococci are biochemically different from the staphylococci in regards to their lack of catalase activity. These bacteria are facultative anaerobes and appear as Gram-positive cocci in pairs and/or chains on a Gram stain...
Identification, classification, and clinical relevance of catalase-negative, gram-positive cocci, excluding the streptococci and enterococci. Several new genera and species of gram-positive, catalase-negative cocci that can cause infections in humans have been described. Although these bacteria w... R,...
病原生物学英文课件:Gram-positive Bacteria.ppt,“六多”:一是感染人数多,全国多达5.5亿人感染过结核菌,约占全国人口的45%,高于全球平均水平。二是患病人数多,全国活动性肺结核、传染性肺结核患病率分别为367/10万和122/10万,有活动性肺结核患者450万,其中传染性
Listerias are motile Gram-positive bacilli and catalase positive. They are facultatively anaerobic and capable of growing over a wide temperature range on simple media. Erysipelothrix rhusiopathiae is a facultative anaerobic, Gram-positive bacillus. It is nonmotile, is catalase negative, and produces...
belong to a diverse group of bacteria known as aerobic actinomycetes, characterized as being Gram-positive rods with partially acid-fast, non-motile, filamentous branches; other properties include being catalase-positive and methenamine silver-positive. Nocardia isolation from clinical samples with the pa...
