Question

Skin grafts are unsuitable for transplantation if the cultures grow?

a. Diptheroids **non pathogenic
b. Micrococcus sp. **gram positive
c. Staphlococcus, coagulase negative ** nonpathogenic and not highly virulent
d. Staphlococcus, coagulase positive **pathogenic and highly virulent

Answer 1

Skin grafts are unsuitable for transplantation if the cultures grow Staphylococcus, coagulase positive, which are pathogenic and highly virulent.

Step-by-step explanation:

Skin grafts are unsuitable for transplantation if the cultures grow Staphylococcus, coagulase positive as they are pathogenic and highly virulent. Staphylococcus, coagulase positive strains, such as Staphylococcus aureus, are known to cause severe skin infections. In contrast, the other options mentioned in the question, including diptheroids, Micrococcus sp., and Staphylococcus, coagulase negative, are non-pathogenic or less virulent and may not pose a significant risk for transplantation.
