Bacterial and mycobacterial cells

Bacterial and mycobacterial cells are prokaryotic microorganisms that serve as the primary pathogens in a vast array of human infections, ranging from acute respiratory distress to chronic conditions like tuberculosis. These cells are distinguished from eukaryotic human cells by unique structural features, most notably the peptidoglycan cell wall in most bacteria and the complex, waxy mycolic acid layer characteristic of the genus Mycobacterium (StatPearls, 2023). These structural differences provide the basis for selective toxicity, allowing pharmacological agents to target essential bacterial processes without significantly harming the host. Common mechanisms of action for drugs targeting these cells include the inhibition of cell wall assembly, interference with the 70S ribosome to block protein synthesis, and the inhibition of enzymes like DNA gyrase or RNA polymerase (NIH, 2022). Despite the historical success of these treatments, the emergence of multi-drug resistant (MDR) strains and the collateral damage to the beneficial human microbiome present ongoing therapeutic challenges (WHO, 2023).
