Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2] Two species are common commensal organisms in the intestines of humans: E. faecalis (90–95%) and E. faecium (5–10%).

2023年5月28日 · One type of important bacteria is called enterococci, which includes more than 17 different species. They’re found in the intestines of nearly every animal on earth. Only a few types of...

2021年4月20日 · Enterococci are Gram-positive facultative anaerobic cocci in short and medium chains, which cause difficult-to-treat infections in the nosocomial setting. They are a common cause of UTIs, bacteremia, and infective endocarditis and …

2023年10月10日 · Enterococcus faecalis (E. faecalis) is one of the most common species. These bacteria also live in the mouth and vagina. They’re very resilient, so they can survive in hot, salty, or acidic...

Enterococci are spherical or ovoid cells arranged in pairs or chains (144, 241). The enterococci are Gram positive, non-spore-forming, obligately fermentative chemoorganotrophs. They are catalase negative, although some species produce pseudocatalase, and they are usually homofermentative, producing lactic acid (144, 192, 241).

Enterococci are Gram-positive catalase-negative, non-spore-forming, facultative anaerobic lactic acid bacteria, and normal inhabitants of the gut flora of humans, many different mammals, birds, fish, reptiles, amphibians, and insects, as well as nematodes [2,3].

Enterococci are gram-positive, facultative anaerobic organisms. Enterococcus faecalis and E. faecium cause a variety of infections, including endocarditis, urinary tract infections, prostatitis, intra-abdominal infection, cellulitis, and wound infection as well as concurrent bacteremia.

Enterococci: From commensals to leading causes of drug resistant infection provides state-of-the-art summaries of what is known about 1) Their origins, distribution in nature and gut colonization, 2) Infection – history, incidence, and pathology, 3) Enterococci as indicators of contamination and in public policy, 4) Infection treatment and ...

2014年2月6日 · Enterococci are commensals of the gastrointestinal (GI) tract of humans and animals, and, in the absence of antibiotics, establish a symbiotic relationship with the human microbiota. In normal circumstances, enterococci are found in low numbers in the colon, as compared with other members of the gut flora (such as anaerobes) (Murray, 2000). The ...

Enterococcus spp. are Gram-positive, facultative, anaerobic cocci, which are found in the intestinal flora and, less frequently, in the vagina or mouth. Enterococcus faecalis and Enterococcus faecium are the most common species found in humans.
