The size of the immune repertoire of bacteria

, 2019
Some bacteria and archaea possess an immune system, based on the CRISPR-Cas mechanism, that confers adaptive immunity against phage. In such species, individual bacteria maintain a "cassette" of viral DNA elements called spacers as a memory of past ...

LysR-Type Transcriptional Regulator Contributes to Pseudomonas cannabina pv. alisalensis Virulence by Regulating Type Three Secretion System

Bacteria
Pseudomonas cannabina pv. alisalensis (Pcal) causes bacterial blight on cabbage. In a previous study, we screened for reduced virulence using Tn5 transposon mutants and identified a LysR-type transcriptional regulator (LTTR) as a potential virulence ...

Plasmid pHXY0908 confers ciprofloxacin heteroresistance to Salmonella enterica serovar typhimurium ATCC 14028 by regulating efflux pump gene expression

BMC Microbiology
Background Salmonella enterica Serovar Typhimurium (S. Typhimurium) is a major global foodborne pathogen. In our previous study, the S. Typhimurium ATCC 14028 strain harboring plasmid pHXY0908 survived at fourfold its ciprofloxacin MIC (MIC0908 = 0.125 ...
