; (2) Gram-negative—cocci and bacilli. Many anaerobic bacteria possess virulence factors that facilitate their pathogenicity (e.g. histolytic enzymes and various toxins). A putrid odour of the affected tissue o
英文: The causative organisms included both gram positive and gram negative bacteria.中文: 引起发炎的细菌包括革兰氐阴性及革兰氐阳性菌种。英文: Labeling gram-negative bacteria using green fluorescent protein中文: 利用绿色荧光蛋白标记革兰氏阴性细菌的研究 ...
The clinically important anaerobic bacteria are six genera of Gram-negative rods (Bacteroides, Prevotella, Porphyromonas, Fusobacterium, Bilophila and Sutterella), Gram-positive cocci (primarily Peptostreptococcus), Gram-positive spore-forming (Clostridium) and non-spore-forming bacilli (Actinomyces, Propionib...
Why is Mobiluncus said to be Gram variable? - it is truly Gram positive - but looks Gram negative because the stains are easily washed away on the decolorization step What does Mobiluncus usually cause? - bacterial vaginosis: vaginitis w/out an inflammatory response ...
However, data on the activity of solithromycin against anaerobic bacteria from the normal intestinal microbiota are scarce. In this study, 1024 Gram-positive and Gram-negative anaerobic isolates from the normal intestinal microbiota were analyzed for in-vitro susceptibility against solithromycin and ...
special handling, as O2 (i.e., open air) is toxic to cultures and they may present as “culture-negative” if exposed; once the specimen arrives in the lab, it is processed under conditions of decreased O2, and any bacteria identified are recultured to determine their sensitivity to ...
metabolic responses of tumor spheroids to the presence of viable and proliferating CRC-relevant bacteria. In a previous report, patient-derived colorectal tumors that were biofilm-positive had higher levels of polyamines compared to biofilm-negative, with N1,N12-diacetylspermine being the most ...
Among all, Gram-positive bacteria constitute the most frequently isolated pathogens (45–65%), followed by Gram-negative bacteria (25–40%) and fungi (3–6%) [1–4]. Infection with mycobacteria and anaerobic bacteria is rare, both of which are found in <0.5% of peritonitis episodes [1]....
Genome annotation and metabolic reconstruction showed that they are Gram-negative bacteria likely involved in acidogenesis, producing acetate and hydrogen from fermentation of sugars, and may play a role in the cycling of sulphur in the digesters. Fluorescence in situ hybridization revealed single rod-...
