Abstract

Antibiotics are antimicrobial agents that target bacteria to treat and prevent bacterial infections. They work by interfering with vital bacterial functions, such as the synthesis of nucleic acid, cell wall, and folate, but also disrupting the plasma membrane and ribosome function. Bacteriostatic antibiotics inhibit bacterial growth and those that are bactericidal kill bacteria. Unfortunately, over time, bacteria have become resistant to antibiotics. This resistance can occur through intrinsic or acquired mechanisms, and bacteria may contain more than one type of bacterial resistance. Bacteria can develop antibiotic resistance mechanisms by reducing intracellular antibiotic concentrations and inactivating or modifying antibiotics and their target sites. The misuse of antibiotics, including excessive use, unnecessary and incorrect prescription, and self-administration, is associated with antibiotic resistance and, therefore, a higher likelihood of extended hospital stays and a greater risk of mortality. To slow the spread of antibiotic resistance, careful antibiotic selection will be crucial, as will the development of new antibiotics and the chemical modification of existing antibiotics to withstand established resistance mechanisms of bacteria. This paper will provide insight into the mechanisms of antibiotics, their effect on bacteria, and the spread of antibiotic resistance. Additionally, this paper will look into the microbiological implications in public health by analyzing challenges regarding antibiotic resistance and potential ways to shed light and raise awareness of antibiotic resistance.
