Virulence and viability of Yersinia pestis 25 years after lyophilization.
When equal volumes of 6% lactose and a broth culture of Yersinia pestis were mixed before freezing, approximately 50% of the cells survived lyophilization and reconstitution on the following day. Concomitantly, the number of viable cells per 50% lethal dose increased from about 16 to 125 organisms. On subsequent storage of the lyophilized cells under vacuum in glass ampoules at 4 degrees C for ...
متن کاملOmics strategies for revealing Yersinia pestis virulence
Omics has remarkably changed the way we investigate and understand life. Omics differs from traditional hypothesis-driven research because it is a discovery-driven approach. Mass datasets produced from omics-based studies require experts from different fields to reveal the salient features behind these data. In this review, we summarize omics-driven studies to reveal the virulence features of Y...
متن کاملViability of Yersinia pestis subcultures in agar stabs.
UNLABELLED Since its identification as the causative agent of plague in 1894, thousands of Yersinia pestis strains have been isolated and stored. Here, we report the ability of Y. pestis to survive up to 47 years in agar stabs, in rubber-stoppered tubes, under refrigeration (+4 to +10°C), although overall subculture recovery rates were poor and inversely related to the length of time stored. Ge...
متن کاملYersinia pestis AcrAB-TolC in antibiotic resistance and virulence.
The efflux pump AcrAB is important in the antibiotic resistance and virulence of several pathogenic bacteria. We report that deletion of the Yersinia pestis AcrAB-TolC homolog leads to increased susceptibility to diverse substrates, including, though unlike in Escherichia coli, the aminoglycosides. Neither is the Y. pestis pump affected by the efflux pump inhibitor phenylalanine-arginine beta-n...
