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...
Introduction The genus Listeria consists of Gram-positive, non-sporeforming rod shaped bacteria which are facultatively anaerobic, catalase positive, oxidase negative and ubiquitous in nature =-=[1]-=-. There are six characterized Listeria species, namely Listeria monocytogenes, Listeria ivanovii, ...
A wide range of aerobic and anaerobic Gram-positive taxa have been associated with fish diseases with new pathogens including Lactococcus lactis subsp. lactis. Lactococcosis and streptoccoccosis have developed into significant constraints of many fish sp
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
Figure 2.Clostridium difficile, a gram-positive, rod-shaped bacterium, causes severe colitis and diarrhea, often after the normal gut microbiota is eradicated by antibiotics. (credit: modification of work by Centers for Disease Control and Prevention) ...
Gram positive rod – Filamentous, branching – Can be beaded • Non acid-fast Aerobic Actinomyces • Colony morphology – Spider or granular center – Branching filaments – Takes up to 7-14 to develop • Key Biochemicals – Catalase negative – Nonmotile – Non-fermenters – Produce H ...
Coagulase is an enzyme that clots blood plasma. This test is performed on Gram-positive, 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...
A Gram-stain-positive, catalase-negative and rod-shaped bacterium was isolated from a brewery environment. Its phylogenetic affiliation was determined usin... MA Ehrmann,P Preissler,M Danne,... - 《International Journal of Systematic & Evolutionary Microbiology》 被引量: 19发表: 2010年 Contamination...
An unknown, strictly anaerobic, Gram-positive, rod-shaped bacterium (strain MOL361T) was isolated from a blood culture of a febrile patient with acute appendicitis and characterized using phenotypic and molecular methods. Fatty acid analysis and biochemical examination indicated that the isolate most ...
The Enterobacteriaceae are Gram-negative rod-shaped bacteria, which are typically motile by virtue of peritrichous flagella and are non-sporing, facultative anaerobes, which will grow in the presence of bile salts. They are oxidase negative, catalase positive, reduce nitrate, and, almost all, ...
