Explanation:
We define antibiotic susceptibility testing as an evaluation of the ability of antibiotics to inhibit bacterial growth. This test is necessary because certain bacteria may have developed resistance to certain antibiotics.
Hence, if the antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline and chloramphenicol disk, then it implies that these antibiotics are all largely effective against Staphylococcus aureus and could be used for treatment of Staphylococcus aureus infection.
Answer:
A. B cells
Explanation:
B cells are involved in the specific immune response that exhibits specificity, memory and self-non-self distinction. This immune response is also called as adaptive immunity. B cells are produced in the bone marrow. An encounter of B cells with antigen activates them for multiplication.
The activated B cells produce plasma cells which in turn produce specific antibodies that bind to the specific antigens and start the adaptive immune response.
