For example, in a 20-generation experiment, a mutation occurring at the 10th generation of bacteria would give 1,024 phage-resistant variants. A mutation occurring at the 17th generation would give only four phage-resistant variants. The number of resistant colonies in Luria's experiments showed ...

Coagulase-negative staphylococci (CoNS) are the most frequent contaminating bacteria; therefore, we aimed to investigate an indicator of CoNS to predict the increase in blood culture contamination rate (ConR). We performed a retrospective study of select
Soon after the entry of antibiotics to widespread use, resistant and multiresistant strains of the bacteria began to spread rapidly. This is a very unfavorable phenomenon because infections caused by antibiotic-resistant bacteria are very difficult to cure, sometimes even impossible5. Therefore, ...
