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....

This study reports a case of Serratia marcescens cellulitis following a snakebite in a 50-year-old woman. The bite was on the dorsum of the right hand with symptoms of envenomation. She developed swelling and cellulitis with tissue necrosis. Wound debridement was performed.  Pus and tissue biopsy cultures yielded Serratia marcescens sensitive to fluoroquinolones, aminoglycosides, third-generati...

Family 18 chitinases have the signature peptide DGXDXDXE forming the fourth beta-strand in the (beta/alpha)8-barrel of their catalytic domain. The carboxyl-end glutamic acid, E315 in Serratia marcescens chitinase A, serves as the acid/base during chitin hydrolysis, and the side-chain of the preceding aspartic acid, D313, helps to position correctly the N-acetyl moiety of the glycosyl sugar unde...

Prodigiosin is a red pigment produced by Serratia marcescens. Prodigiosin is regarded as a promising drug owing to its reported characteristics of possessing anti-microbial, anti-cancer, and immunosuppressive activity. A factorial design was applied to generate a set of 32 experimental combinations to study the optimal conditions for pigment production using crude glycerol obtained from local b...

Serratia marcescens ATCC 13880 is the type strain of the species and a commonly used quality control strain. Here, we present the annotated genome assembly of 5.13 Mbp (59.8% G+C content) as submitted to NCBI under accession no. JOVM00000000.

Phages infecting Serratia marcescens, a common causative agent of nosocomial infections, have potential therapeutic applications. Here, we report the complete genome of the novel S. marcescens phage BF, representing the third-largest phage genome sequenced to date.

The pigmented strain Serratia marcescens ATCC 274 had a higher buffering capacity and a higher membrane H conductance than S. marcescens GP, a spontaneous nonpigmented mutant of ATCC 274. The data suggest that mutations which apparently affect only the synthesis of a secondary metabolite can modify buffering capacity and passive H conductance.
