Home Tools 35. During the first two hours after the skin is broken by a fresh shallow wound, what is likely to happen to the commensal bacteria from the skin's surface that end up inside the wounded area? a. cationie peptides, such as cathelicidin or defensins, secreted by epithelial cells and neutrophils may kill the bacteria by disrupting the bacterial plasma membrane b. neutrophils from the peripheral blood will enter the wounded area and ingest the bacteria. c B cells will mount an effective response to coat the bacteria with antibodies d. A and B are correct

Explanation / Answer

35. During the first two hours after the skin is broken by a fresh shallow wound, the commensal bacteria from the skin's surface that end up inside the wounded area will be killed by the cationic peptides such as cathelicidin or defensins secreted by epithelial cells and neutrophils which act by disrupting the bacterial plasma membrane. Also, neutrophils from the peripheral blood enter the site of the wound and ingest the bacteria. So, the correct option is option D, A and B are correct.
