IMMUNOLOGY

Detailed explanation-1: -Methicillin-resistant Staphylococcus aureus (MRSA) is a cause of staph infection that is difficult to treat because of resistance to some antibiotics. Staph infections-including those caused by MRSA-can spread in hospitals, other healthcare facilities, and in the community where you live, work, and go to school.

Detailed explanation-2: -Only a few of the MRSA isolates were found to be resistant to vancomycin (0%), cloxacillin (17.9%), gentamycin (20.68%) amikacin (10.2%) and chloramphenicol (23.1%). -lactam antibiotics like cefoxitin (100%) and penicillin (100%) were found to be ineffective against MSSA too.

Detailed explanation-3: -Staph can usually be treated with antibiotics. But over the decades, some strains of staph, like MRSA, have become resistant to antibiotics that once destroyed them. MRSA was discovered in 1961. It’s now resistant to amoxicillin, methicillin, oxacillin, penicillin, and other common antibiotics known as cephalosporins.

Detailed explanation-4: -An increasing number of people are being diagnosed with skin infections caused by Staphylococcus aureus (“staph”) bacteria that are resistant to many antibiotics (drugs that kill bacteria). These resistant strains of staph are known as “MRSA” (methicillin-resistant Staphylococcus aureus).
