Evolution and phenotypic diversification in serratia marcescens biofilms
… the characterization of biofilm development of Serratia marcescens MG1, the analysis of the biofilm dispersal population, and the identification of the conditions that trigger phenotypic diversification. Furthermore, it provides an insight into the molecular understanding of how phenotypic …

Secretion of the chitinolytic machinery in Serratia marcescens
… for export to the periplasm (two-step systems). Serratia marcescens is an important opportunistic human pathogen and has gathered a lot of interest due to its repertoire of secreted proteins. These include the haem-scavenging protein HasA, which is secreted by a Type 1 secretion system, and the …

Novel pleiotropic regulators of gas vesicle biogenesis in Serratia
Serratia sp. ATCC 39006 (S39006) is known for producing carbapenem and prodiginine antibiotics; 1-carbapen-2-em-3-carboxylic acid (car) and prodigiosin. It displays different motility mechanisms, such as swimming and swarming aided by flagellar rotation and biosurfactant production. In addition, …

Characterization of ToxINPa-sensitive bacteriophages of Serratia sp. ATCC 39006
… ToxINPa into the Gram-negative enterobacterium, Serratia sp. ATCC 39006 (S39006). A novel environmental S39006 phage, ΦCBH8, that is sensitive to ToxINPa-mediated Abi was isolated, characterized, and compared to its spontaneous “escape” mutants that were insensitive to ToxINPa. Characterization …

Novel regulators of antibiotic biosynthesis in Serratia sp. ATCC 39006
… controlled hyperproduction. The enterobacterium *Serratia* sp. ATCC 39006 (S39006) is a useful Gram-negative model for studies on the biosynthesis and regulation of bioactive secondary metabolites, particularly two antibiotics – prodigiosin and a carbapenem. Both compounds are tightly regulated in …

Environmental bacteriophages infecting Dickeya and Serratia species: receptors and diversity
… family phages in nosocomial pathogen Serratia produced inconclusive results. Phageresistance due to random transposon mutagenesis identified genes encoding transcription factors and regulators, but none directly linked to capsular polysaccharide production. Thirteen phages were capable …

Inhibition of Proteus Swarming by the Metabolic Products of Serratia Marcescens
… Fulton (14) observed that pigmented strains of Serratia marcescens grown in mixed culture with Proteus species exerted an inhibitory effect on swarming. The purpose of this research is to determine what effect the pigment, prodigies in, and the other metabolic products of Serratia marcescens …

Secretion and regulation of the chitinolytic machinery in <i>Serratia marcescens</i>
… in either a one- or a two-step process. Serratia marcescens is renowned as a prolific secretor of proteins and is one of the most effective microbes at extracellular chitin degradation. To achieve this S. marcescens secretes three chitinases (ChiA, ChiB and ChiC) as well as a chitin …

The Persistence of the Bacterium Serratia Marcescens in the Intestinal Tracts of Turtles
The problem. The persistence of Serratia marcescens in the intestinal tracts of turtles was investigated. Procedure. Food pellets were injected with Serratia marcescens and fed to the experimental turtles. The retention time of S. marcescens in the intestinal tracts of three genera of turtles was …

N-acylhomoserine lactone regulation of adhesion and biofilm differentiation in Serratia marcescens MG1
Serratia marcescens is an opportunistic pathogen involved in predominantly nosocomial infections, however, it is also implicated as a common cause of microbial keratitis. Since many S. marcecens strains are also resistant to multiple antibiotics, this organism represents a growing public health …

Analysis of the diverse antibacterial strategies used by <i>Serratia marcescens</i> Db10
The Gram-negative bacterium, <i>Serratia marcescens</i>, is an important opportunistic human pathogen capable of causing serious infections, particularly in immunocompromised patients. <i>S. marcescens</i> Db10 is an insect pathogen that is closely related to <i>S. marcescens</i> strains which …

Investigating the key components of the chitinase secretion system in <i>Serratia marcescens</i>
The opportunistic bacterial pathogen <i>Serratia marcescens</i> secretes a ‘chitinolytic machinery’ comprising ChiA, ChiB, ChiC, and Cbp21, that is essential for the efficient utilisation of the extracellular polysaccharide chitin. Secretion of these proteins appears to be a two-step process in …

New Pleiotropic Co-Regulators of Gas Vesicle and Secondary Metabolite Production in Serratia sp. ATCC39006
Serratia sp. ATCC39006 (S39006) is a rod-shaped, motile, Gram-negative phytopathogenic bacterium. It is the only enterobacterium known to make gas vesicles (GVs) naturally. GVs are proteinaceous, intracellular organelles used by bacteria to enable upward flotation in aquatic environments. S39006 …

Novel pleiotropic regulators of flotation, secondary metabolite production, and virulence in Serratia sp. ATCC 39006
Serratia sp. ATCC 39006 (S39006) is a Gram-negative, rod-shaped enterobacterium known for the production two antibiotics; the β-lactam, 1-carbapen-2-em-3-carboxylic acid (a carbapenem) and the red-pigmented tripyrrole, 2-methyl-3-pentyl-6-methoxyprodigiosin (prodigiosin; a prodiginine). It also …

The genomic characterization of carbapenemase-producing Serratia marcescens at a tertiary hospital in South Africa
Background Serratia marcescens is an opportunistic nosocomial pathogen, and recent reports have highlighted the rapid increase in multidrug resistance in this organism. There is a paucity in genomic data for carbapenem resistant S. marcescens (CRSM). Methods A retrospective cohort study describing …

The role of post-transcriptional regulators in pathogenesis and secondary metabolite production in Serratia sp. ATCC 39006.
Serratia sp. ATCC 39006 (S39006) is a Gram-negative bacterium that is virulent in plant (potato) and animal (Caenorhabditis elegans) models. It produces two secondary metabolite antibiotics, prodigiosin and a carbapenem, and the plant cell wall degrading exoenzymes, pectate lyase and cellulase. A …
