Colwell, R. R. (Georgetown University, Washington, D.C.), and M. Mandel. Adansonian analysis and deoxyribonucleic acid base composition of Serratia marcescens. J. Bacteriol. 89:454-461. 1965.-A total of 33 strains of Serratia marcescens were subjected to Adansonian analysis for which more than 200 coded features for each of the organisms were included. In addition, the base composition [express...

Objectives/Goals I really enjoyed my project this year. In my project, I tested how temperature affected the pigmentation of four different bacteria. From my research, I knew that the bacterium Serratia marcescens alters its color at different temperatures, and I wanted to explore this. I also wanted to see if this applied to other pigmented bacteria. Methods/Materials My project consisted of q...

A non-pigmented strain of Serratia marcescens was isolated ante-mortem and at post-mortem from the blood of six dogs under intensive medical care. Clinical, bacteriological and pathological evidence confirmed death to be associated with septicaemia from this Gram-negative organism. I N T R O D U C T I O N Serratia marcescens has been known to exist in both pigmented and non-pigmented varieties ...

BACKGROUND In November 2011, 6 patients who were in the ICU of the Sri Guru Ram Dass Institute of Medical Sciences and Research acquired an infection which was caused by Serratia marcescens. We investigated the cause of the increase in frequency of the isolation of Serratia marcesens from hospitalized patients. METHODS Various samples from patients and environmental sources, which were collec...

In this article, we present the first case of necrotizing fasciitis affecting the abdominal wall caused by Serratia marcescens and share results of a focused review of S. marcescens induced necrotizing fasciitis. Our patient underwent aorto-femoral bypass grafting for advanced peripheral vascular disease and presented 3 weeks postoperatively with pain, erythema and discharge from the incision s...

The enzyme LuxS is responsible for the production of autoinducer-2 (AI-2), a molecule that has been implicated in quorum sensing in many bacterial species. This study investigated whether there is a luxS-dependent signalling system in the Gram-negative bacteria Serratia spp. Serratia marcescens is a broad-host-range pathogen and an important cause of nosocomial infections. Production of AI-2 ac...

Through the hydrolysis of casein, a cultural characteristic has been established in the preliminary identification of Serratia marcescens. Compared against 438 strains of the families, Pseudomonadaceae and Enterobacteriaceae, this organism has a reproducible capability to decompose casein, while most other Gram-negative bacilli failed to produce any hydrolysis, or, at the most, hazy zones only....
