Generally, SCVs display a small colony size, a low growth rate, and atypical colony morphology (16). Biochemical char-acteristics of SCVs include a deficiency in electron transport or in thymidine biosynthesis (4, 23). SCVs are specialized for intracellular persistence in host cells and have been shown to Generally, SCVs display a small colony size, a low growth rate, and atypical colony morphology (16). Biochemical characteristics of SCVs include a deficiency in electron transport or in thymidine biosynthesis (4, 23). Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans.

Eight Pseudomonas putida presented two clusters, two Pseudomonas spp. were not clonal, and all were resistant to the tested antibiotics except tetracycline. A mannitol salt plate is a type of bacterial culture plate that uses mannitol salt agar. As a result, this type of agar (which is 7.5 percent salt) will only grow staphylococcus bacteria and a few different kinds of enterococcus bacteria that can survive the conditions, including enterococcus faecalis. Enterococcus gallolyticus (previously known as Streptococcus bovis) can cause bacteremia and is associated with colon cancer.
