RPOB stands for Rifampicin Resistance Determining Region of the bacterial gene rpoB. It is a critical point mutation responsible for antibiotic resistance in a variety of bacterial species. There are several synonyms for RPOB gene such as Rifampin Resistance, Rifampicin Resistance, and Rifampicin Resistance Mutations. Rifampicin Resistance mutations can be identified through molecular techniques such as PCR and sequencing of the rpoB gene. Knowledge of these mutations is essential for the effective treatment of bacterial infections. These synonyms are widely used in clinical microbiology and research to describe rifampicin resistance in bacterial species such as Mycobacterium tuberculosis and Staphylococcus aureus.
