1. An undercooked boiled egg was received in the microbiology laboratory with a request culture and identification. This egg was served in a pack lunch during a birthday party. All guests who ate this egg were brought to the hospital for vomiting and dehydration. Some had bouts of diarrhea. The signs and symptoms were short-lived after treatment was received. The egg was homogenized in tryptic soy broth. This was plated in sheep’s blood agar plate and MacConkey agar plate. After 24 hours of incubation, the following observations were noted:
Sheep’s blood agar plate: 4+ (many) beta hemolysis, creamy white colonies
MacConkey agar plate: no growth
The gram stain result of the isolate yielded gram-positive cocci, mostly in clusters.
If Staphylococcus aureus is suspected, list 3 tests that will be most relevant in its identification – i.e. to differentiate it from other gram-positive cocci
19) Which of the following BEST describes an agent that is bactericidal?
A) Windex.
B) It suspends bacterial growth.
C) It kills the bacteria.
