Heteroresistance is a term that refers to the capacity of bacteria to exhibit resistance to antibiotics, even when only a portion of the bacterial population possess resistance genes. This phenomenon has been reported in several studies, and new synonyms to describe it have been proposed to expand scientific vocabulary and improve communication among researchers. Some of the synonyms for heteroresistance include "subpopulation resistance," "partial resistance," and "minority resistance." These terms underscore the idea that only a small portion of the bacterial population has the ability to resist antibiotics. Employing a variety of terms can enhance scientific understanding of the phenomenon and help researchers develop new strategies to fight bacterial infections.
