Many bacteria use cell-cell communication to monitor their population density, synchronize their behaviour and socially interact. This communication results in a coordinated gene regulation and is generally called quorum sensing. In gram-negative bacteria, the most common quorum signal molecules are acylated homoserine lactones (AHLs), although other low-molecular-mass signalling molecules have...

Strains of Serratia marcescens, originally isolated from the gut lumen of adult female Anopheles stephensi mosquitoes, established persistent infection at high rates in adult A. stephensi whether fed to larvae or in the sugar meal to adults. By contrast, the congener S. fonticola originating from Aedes triseriatus had lower infection in A. stephensi, suggesting co-adaptation of Serratia strains...

Serratia marcescens is commonly isolated from the urine of patients with an indwelling urinary catheter and in the absence of symptoms is often regarded as a contaminant. A case of fatal Serratia marcescens septicaemia with meningitis, brain abscesses, and myocarditis discovered at necropsy is described. The patient was an 83 year old man with an indwelling urinary catheter who suffered from se...

This investigation concerns identification of alkaline phosphatase production by bacterial organisms, as detected by a blue color resulting from conversion of indolyl phosphate to indigo. Coagulase-positive Staphylococcus produced alkaline phosphatase; coagulase-negative Staphylococcus did not. Serratia did not produce alkaline phosphatase; those Enterobacteriaceae we tested did. Thus, this tes...

The biochemical, serological, and epidemiological characteristics of 95 strains of Serratia marcescens isolated at the Boston City Hospital were examined. Several strains were shown to be endemic, and the majority of isolates were cultured from urine or respiratory secretions. Serratia species were highly resistant to polymyxin B and the cephalosporins, and various proportions were also resista...

Serratia marcescens strains are ubiquitous bacteria isolated from environmental niches and also constitute emergent nosocomial opportunistic pathogens. Here, we report on the draft genome sequence of S. marcescens strain RM66262, which was isolated from a patient with urinary tract infection in the Bacteriology Service of the Rosario National University, Rosario, Argentina.

Serratia marcescens, a member of the family Enterobacteriaceae, is the causative agent of various types of wound infections. We report a high-quality draft genome sequence of S. marcescens strain VGH107, which was isolated from a patient with an infection from a snakebite wound.

Serratia marcescens is an important opportunistic organism that causes nosocomial infections. Bacteriophage therapy has the potential to control S. marcescens infection. We present here the complete genome sequence of a lytic S. marcescens bacteriophage, SM9-3Y, which is a linear double-stranded DNA genome of 39,631 bp with 50.7% G+C content.
