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 …

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 …

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 …

Specialised Effectors and Accessory Proteins Important in the Antibacterial Type VI Secretion System of <i>Serratia marcescens</i>
… machinery. The opportunistic human pathogen, <i>Serratia marcescens</i>, displays a highly effective and offensive anti-bacterial T6SS. Multiple secreted effectors delivered by the T6SS of S. marcescens are known to represent efficient weapons against susceptible target cells. However, prior to …

The cloning , expression and characterisation of bacterial chitin-binding proteins from pseudomonas aeruginosa , serratia marcescens, photorhabdus luminescens and photorhabdus asymbiotica.
… Prokaryotic chitin-binding proteins from Serratia marcescens, Pseudomonas aeruginosa, Photorhabdus asymbiotica and Photorhabdus luminescens were cloned, over-expressed in E. coli and purified to homogeneity via (His)6 affinity tags. The activity and specificity of these proteins was tested …

Investigation into the transcriptional regulation and role in virulence of the Type VI Secretion System of <em>Serratia marcescens</em> Db10
… survive in its particular environmental niche. Serratia marcescens (Sma) is an opportunistic enteric pathogen which is responsible for causing severe hospital acquired infections in vulnerable patients. The insect pathogen Sma Db10 possesses a functional T6SS which targets antibacterial effector …

Biological control of a plant pathogen and pest by expression of a cloned Serratia marcescens chiA gene and Bacillus thuringiensis cryIA(c) gene in endophytic bacteria
… The gene coding for the major chitinase of S. marcescens, chiA, was cloned under the control of the tac promoter by PCR amplification. The gene contained the endogenous Shine Dalgarno sequence 7 bases upstream of the ATG start codon in the plasmid pTC33. The plasmid ptacchiA had previously been …

Charakterisierung der Endonuklease Ivon Escherichia coli K-12 und Anwendung des Enzyms in einembakteriellen Suizidsystem
… Kombination mit der extrazellulären Nuklease von Serratia marcescens verwendet. In dem Suizidsystem werden die signalpeptid-deletierten Nukleasegene vom Lambda-PL- Promoter kontrolliert. Eine thermoinduzierte Expression verringerte das Zellüberleben auf 10-5 - 10-6 und mehr als 90% der DNA wurde …

Structural studies to inform antimicrobial drug discovery and the basis of immunity against T6 effectors
… structures of the proteins Rap1a and Rap2a from Serratia marcescens, inhibitors of the peptidoglycan amidase toxins secreted by some Gram-negative bacteria employing the Type VI secretion pathway, were determined by molecular replacement and analysed.
