Fitness cost bacteria
WebMay 2, 2006 · Such reductions in fitness (reduced growth rate and/or virulence) are typical for most types of resistance mechanisms and bacterial species (10–14). Furthermore, it has been demonstrated that these costs can be compensated by second-site mutations, often without loss of resistance ( 10 , 15 – 21 ). WebJan 24, 2024 · The cost to the ‘fitness’ of an organism is it’s ability to replicate and survive in a competitive environment.
