Many antibiotics used in modern medicine are compounds made by fungi that inhibit bacterial
protein synthesis. Describe the specific effect of the following antimicrobial drugs:
(i) Chloramphenicol
(ii) Rifamycin
clostridium botulinum is a bacterium usually present in soil that may cause botulism. Briefly explain why one or few cells of a pathogenic bacterium, such as clostridium botulism, by itself typically does not secrete a toxin, despite the species as a whole being characterized as toxin producing.
