Detailed explanation-1: -Mycobacterium tuberculosis is intrinsically resistant to many antibiotics, limiting the number of compounds available for treatment. This intrinsic resistance is due to a number of mechanisms including a thick, waxy, hydrophobic cell envelope and the presence of drug degrading and modifying enzymes.
Detailed explanation-2: -Extensively drug-resistant tuberculosis (XDR-TB) is resistant to RIF, INH, streptomycin (SM), and pyrazinamide, as well as to aminoglycosides (kanamycin, amikacin, capreomycin) and fluoroquinolones (ofloxacin, moxifloxacin).
Detailed explanation-3: -Methicillin-Resistant Staphylococcus Aureus This type of bacteria is resistant to many antibiotics, including methicillin. Most methicillin-resistant Staphylococcus aureus, or MRSA, infections contracted outside of a hospital are skin infections.
