What is (1) gram stain? and (2) catalase? GBS is a gram-positive COCCUS, and is catalase negative. Listeria is a Gram-Positive ROD, and is catalase positive.

The first-century Roman historian Josephus recorded that King Herold was fatally afflicted by skin itching, abdominal distenstion, and gangrene of his "privy parts." This is likely a description of this modern-day infective condition.
What is Fournier's gangrene? -- a form of polymicrobial (aerobic and anaerobic -- beta strep, staph, Bacteroides, and Clostridium) otherwise classified as one of the "flesh-eating" syndromes, notably targeting the perineal area, especially in older men. Even today the death rate approaches 80%.

Streptococcus bovis and Enterococcus faecium can both look the same on blood agar (slightly alpha hemolysis), but can be easily separated by this simple test
What is PYR? Both organisms are gram-positive cocci and are both Lancefield group D. Strep bovis is PYR negative E. faecium is PYR positive.

Staph aureus and Staph haemolyticus can look the same on blood agar, but can be separated by this simple test.
What is coagulase? Both are catalase-negative gpc. Staph aureus is coagulase positive. Staph haemolyticus is coagulase negative.
