Question

Bacteria collected from a severely inflamed wound are sent to the lab for analysis. The results come back as follows: Gram-positive cocci in irregular clusters, kinase and coagulase positive, and able to grow in the presence of most antibiotics except vancomycin. The bacteria in the wound are most likely:

Answer 1

Answer:

Explanation:

Since the result shows the bacterial culture was irregular clusters of Gram-positive cocci, kinase and coagulase positive, it is should be Staphylococcus aureus and furthermore, it is able to grow in the presence of most antibiotics except vancomycin, the bacterial most likely methicillin-resiistant Staphylococcus aureus (MRSA). This organism is believed to harbor a chromosomal gene called mecA which confers on it the ability to be ressitant to methicillin and other β-lactam drugs antibiotics such as penicillin, cephalosporins  and carbapenems
