In the case of bacteria, genes can be transferred by mobile genetic elements such as plasmids or they can be inherited. 10 Sub-inhibitory and sub-therapeutic levels of antibiotics can cause changes in gene expression, horizontal gene transfer (HGT) or mutagenesis, thereby contributing to the development of resistance. 16 …
WebThe major mechanism of resistance to chloramphenicol is the production of a chloramphenicol acetyltransferase which converts the drug to either the monoacetate or the diacetate. These derivatives are unable to bind to the bacterial 50S ribosomal subunit and thus cannot inhibit peptidyl transferase activity. The chloramphenicol …
