Gram Positive Cocci
A 70-yrs-old female patient was readmitted to a local hospital with fever and chills following cardiac surgery at a major teaching institution. Blood cultures were taken and a gram-positive coccus grew-positive coccus grew from the blood cultures within 24-hours. Initial tests indicated that this isolate was resistant to penicillin. Which of the following is the most likely identification? (AIPG 2012)
|B||Group A streptococcus|
|C||Group B streptococcus|
a. Enterococci cause a wide variety of infections ranging from less serious—for example, urinary tract infections—to very serious, such as septicemia.
b. A gram-positive coccus resistant to penicillin must be assumed to be entero coccus until other, more definitive biochemical testing places the isolate in one of the more esoteric groups of gram-positive cocci.
