Abstract:

E Endophytic bacteria have several advantages, including controlling plant pathogens and increasing plant growth. As a biological control, endophytic bacteria can suppress the development of plant pathogenic fungi. This study aimed to obtain endophytic bacteria and the consortium of endophytic bacteria that can inhibit the growth of C. oryzae. The study used a Completely Randomized Design (CRD) for studying the ability of endophytic bacteria using eight isolates: Bacillus sp HI, Bacillus sp SJI, B. cereus P14, B. cereus Se07, Serratia marcescens strain JB1E2, S. marces-cens strain JB3, S

During monthly milk sampling performed during a 4-month period, S marcescens was isolated from 38.8 to 62.3% of composite milk samples obtained from cows from which S marcescens was previously isolated. Few cows infected with S marcescens had evidence of clinical mastitis. Somatic cell count value was associated with isolation of S marcescens

Abstract BACKGROUND: Serratia marcescens is a well-known Gram-negative, rod-shaped bacterium commonly found in soil, animal skin, hospital environment, and plant-based raw materials. It is an opportunistic pathogen that causes serious infections, including pneumonia, bloodstream infection, wound infection, meningitis, and respiratory and urinary tract infections. Due to multiple resistant strains of S. marcescens being identified, new and effective plant-based antimicrobial compounds/drugs against S. marcescens must be searched.

Abstract:

Serratia marcescens is an opportunistic pathogen that causes diverse nosocomial infections. S. marcescens has developed considerable resistance to different antibiotics and is equipped with an armory of virulence factors. These virulence factors are regulated in S. marcescens by an intercellular communication system termed quorum sensing (QS). Targeting bacterial virulence and QS is an interesting approach to mitigating bacterial pathogenesis and overcoming the development of resistance to antimicrobials. In this study, we aimed to evaluate the anti-virulence activities of secnidazole on a cli

Abstract:

Serratia marcescens is an opportunistic nosocomial pathogen and causes wound and burn infections. It shows high resistance to antibiotics and its pathogenicity is mediated by an arsenal of virulence factors. Another therapeutic option to such infections is targeting quorum sensing (QS), which controls the expression of different S. marcescens virulence factors. Prevention of QS can deprive S. marcescens from its bacterial virulence without applying stress on the bacterial growth and facilitates the eradication of the bacteria by immunity.

ABSTRACT HasA is the secreted hemophore of the heme acquisition system (Has) of Serratia marcescens. It is secreted by a specific ABC transporter apparatus composed of three proteins: HasD, an inner membrane ABC protein; HasE, another inner membrane protein; and HasF, a TolC homolog. Except for HasF, the structural genes of the Has system are encoded by an iron-regulated operon. In previous studies, this secretion system has been reconstituted in Escherichia coli, where it requires the presence of the SecB chaperone, the Sec pathway-dedicated chaperone.

Expression of shlBA is under the positive control of FlhDC, which is repressed by RssAB signaling.

Abstract:

Serratia marcescens is a versatile opportunistic pathogen that can cause a variety of infections, including bacteremia. Our previous work established that the capsule polysaccharide (CPS) biosynthesis and translocation locus contributes to the survival of S. marcescens in a murine model of bacteremia and in human serum. In this study, we determined the degree of capsule genetic diversity among S. marcescens isolates. Capsule loci (KL) were extracted from >300 S. marcescens genome sequences and compared. A phylogenetic comparison of KL sequences demonstrated a substantial level of KL diversi

Using biochemical and genetic approaches, we have identified a major source of this cytotoxic activity. Both heat and protease treatments abrogated the cytotoxicity of S. marcescens culture filtrates towards HeLa cells, suggesting the involvement of one or more protein factors. A screen for in vitro cytotoxic activity revealed that S. marcescens mutant strains that are deficient in production of a 56-kDa metalloprotease are significantly less cytotoxic to mammalian cells.
