Sixty-four patients with malignant diseases from whom Serratia marcescens was isolated from various sources were studied regarding their antibody responses to somatic O antigens of this microorganism. Antibodies were titrated by the passive hemagglutination test. An antibody response was considered present when either a fourfold or greater rise in antibody titers between two consecutive serum s...

β-carotene is a commonly used food colorant. In this work, a novel β-carotene producing strain, Serratia marcescens RB3, was isolated and identified by physiological and biochemical tests, as well as 16S rDNA sequence analysis. The production of β-carotene by S. marcescens RB3 was identified through HPLC analysis. The cultivation conditions for β-carotene production by S. marcescens RB3 were op...

conclusions p. aeruginosa and s. marcescens can be good candidates for the detoxification of cr (vi) in soltan abad river. results the results indicated that pseudomonas aeruginosa and serratia marcescens were the most resistant bacteria with mics of 200 and 150 mg/l, respectively. both bacteria completely reduced 25 and 50 mg/l of cr (vi) in 36 hours and 48 hours, respectively. the growth rate...

The wild strain of Serratia marcescens rapidly degraded threonine and formed aminoacetone in a medium containing glucose and urea. Extracts of this strain showed high threonine dehydrogenase and "biosynthetic" threonine deaminase activities, but no threonine aldolase activity. Threonine dehydrogenase-deficient strain Mu-910 was selected among mutants unable to grow on threonine as the carbon so...

Some strains of S. marcescens are capable of producing pigment, the intensity of which ranges from dark red to pale pink, depending on the age of the colonies. The pigment can be present after incubation at room temperature but usually disappears after subculturing. The pigment was extractred by 1902 and named "prodigiosin" . Serratia marcescens has a predilection for growth on foodstuffs, espe...

In recent years, Serratia marcescens has become established in certain localities as an agent of hospital infection and cross-infection (Clayton & von Graevenitz, 1966; Wilfert, Barrett & Kass, 1968; Davis, Foltz & Blakemore, 1970; Wilkowske, Washington, Martin & Ritts, 1970). In general, strains of S. marcescens isolated from infective lesions differ from those from other sources in being non-...

Serratia marcescens (Chromobacterium prodigiosum) is a freeliving saprophyte generally regarded as being non-pathogenic (Wilson and Miles, 1955). There is, however, reason to believe that under certain conditions this organism may be pathogenic. Three instances are here reported in which S. marcescens infection of the peritoneum occurred during peritoneal dialysis for acute renal failure. All t...

Serratia marcescens is a Gram-negative rod intrinsically resistant to polymyxins and usually associated with wound, respiratory and urinary tract infections. The whole genome of the first GES-5-producing S. marcescens isolated from a Brazilian patient was sequenced using Ion Torrent PGM System. Besides blaGES-5, we were able to identify genes encoding for other β-lactamases, for aminoglycoside ...

A genetic system for the selection of clones coding for integration host factor and HU homologs is described. We demonstrate that the himA and hip genes of Serratia marcescens and Aeromonas proteolytica can substitute for the Escherichia coli genes in a variety of biological assays. We find that the sequence and genetic organization of the himA and hip genes of S. marcescens are highly conserved.

Serratia marcescens has become an important nosocomial pathogen. During a period of seven years 123 strains, both pigmented and non-pigmented varieties were isolated. Their biochemical characteristics, antibiotic susceptibility pattern and clinical significance are described. The aminoglycosides appeared to be the most effective agents against this organism. "Compromised" patients were most vul...
