Meanings of chromosomal mutation in English

USA300 strains were differentiated by a stable chromosomal mutation in gyrA conferring quinolone resistance.

Bacterial chromosomal mutations that confer antibiotic resistance often have deleterious effects that impose costs on reproductive fitness.

The presence of genotoxic agents in the environment may cause chromosomal mutations through different mechanisms, which are associated with serious health effects.

This study therefore sought to identify chromosomal mutations and plasmid-mediated resistance as possible mechanisms of fluoroquinolone resistance from clinical isolates in Ghana.

Characterized mechanisms of colR in K. pneumoniae are largely due to chromosomal mutations in two-component regulators, although a plasmid-mediated colR mechanism has recently been uncovered.
