When it is cultured on blood agar plates it produces large zones of beta-hemolysis. They are catalase-negative and in ideal conditions it has an incubation period of about 1-3 days. It is an infrequent part of the skin flora. It is the cause of many important human diseases, ranging from mild superficial skin infections...
Enterococcus faecalis "“ formerly classified as part of the Group D Streptococcus system "“ is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals.
