Streptococcus faecalis also known as strep D, is now known as Enterococcus faecalis. Enterococcus faecalis is part of the Enterococcaceae family. This organism is a gram positive and usually occurs in pairs called diplococci. It is facultative anaerobic, and is nonmotile. This organism is a lactose fermenter and can be grown in 6.5% NaCL. Enterococcus faecalis is considered non-hemolytic, meaning it does not break down blood cells. Enterococcus faecalis is part of normal flora in the intestines of humans, but can be found in water, soil and plants. If Enterococcus faecalis is found in others places of the body, other than the intestines, it becomes opportunistic and can cause major problems for an individual. This is commonly known as a nosocomial infection, because it becomes a concern for immunosuppressed individuals. Also Enterococcus faecalis infections can develop when a nurse neglects to clean an intravenous catheter or rectal thermometer, and if the nurse neglected to clean those most likely its being spread to other patients. Enterococcus faecalis can cause endocarditis, bacteremia, urinary tract infections, meningitis and other hospital related infections. Unfortunately, Enterococcus faecalis is resistant to most commonly used antibiotics like cephalosporins and aminoglycosides, and a new study suggests that its becoming more resistant to vancomysin. Treatment for an infection by Enterococcus faecalis would be amoxicillin if the organism is susteptible. Treatment for Enterococcus faecalis that is resistant would consist of taking linezolid and daptomycin.
The results from the gram positive enterics included:
Taxo P (optichin) Resistant to Optichin
Bile Esculin Positive for Group D Strep
6.5% NaCL Positive for Growth
