Question
There are fewer antifungal, antiprotozoan, and anthelminth drugs compared to antibacterial drugs because these organisms O do not cause many human infections O are not affected by antimicrobics O are so similar to human cells that selective drug toxicity is difficult to achieve. O are parasites found inside human cells. O have fewer target sites compared to bacteria. QUESTION 22 Which antimicrobic does not interfere with protein synthesis? O aminoglycosides O tetracyclines erythromycin O chloramphenicol QUESTION 23 Penicillins and cephalosporins O interfere with DNA synthesis. O are metabolic analogs of PABA and block folic acid synthesis O attach to the 30S ribosomal subunt and disrupt protein synthes O damage cell membranes O block the peptidases that cross-link glycan molecules QUESTION 24 The cellular basis for bacterial resistance to antimicrobics include O bacterial chromosomal mutations. O synthesis of enzymes that alter drug structure. prevention of drug entry into the cell. O alteration of drug receptors on cell targets All of the choices are correct QUESTION 25 Antibiotics are derived from all the following except Penicilium O Bacilus O Staphylococcus O Streptomyces Cephalosponum.Explanation / Answer
