Rifampin resistance is a heritable trait that increases the fitness of individuals compared to susceptible individuals.

Rifampin resistance is caused by a point mutation in the rpoB gene.

A mutation occurred in the rpoBgene of one cell, allowing the mutant cell to grow and divide.

Drug-resistant strains now account for about 10 percent of the Mycobacterium tuberculosis-caused infections throughout the world.
