A Gram-negative, rod-shaped, urea-dissolving and non-spore-forming bacterium, designated strain NiVa 51T, was isolated from water of the River Torsa in Hasimara, Jalpaiguri district, West Bengal, India. On the basis of 16S rRNA gene sequence similarity, strain NiVa 51T was shown to belong to the γ-Proteobacteria and to be related to Serratia marcescens subsp. sakuensis (98·35 %) and S. marcescens subsp. marcescens (98·30 %); however, strain NiVa 51T exhibited only 43·7 % similarity to S. marcescens by DNA–DNA hybridization. The G+C content of the genomic DNA of the isolate was 60 mol%. Both bi

Developing resistance mechanisms leads to various nosocomial infections caused by opportunistic bacteria. Serratia marcescens are well known to be opportunistic and are equipped with an armory of virulence factors against host immune response. The study aims to detect the immune defense in patients infected with multidrug-resistant S. marcescens. The study includes 132 clinical samples, including burn, wound, otitis media, and urinary tract infection (UTI) at several hospitals in Baghdad, Iraq. All isolates are identified by cultivation on MacConkey agar, nutrient agar, and blood agar, followe

Our study was conducted to detect virulence genes in Serratia marcescens. It has many virulence genes that cause nosocomal infections in immunocompromised persons and neonates. A total of 24/100 (24%) S. marcescens were obtained from neonates suffering from meningitis, and they were identified using culture characteristics biochemical- tests and confirmed by Polymerase chain reaction (PCR) technique, using the 16S rRNA gene.

Serratia marcescens is a rare opportunistic pathogen that produces a red pigment and possess a serious threat to vulnerable people in healthcare settings. This study aimed to identify the virulence genes (cnfI, sat, hlyA, PhIA, ShIA, ShIB, swr, and sepA) in clinical isolates of S. marcescens. For that purpose, 152 samples were collected from various clinical sources including burns, wounds, and urinary tract infections. Cultural characteristics and biochemical tests were relied upon for the initial diagnosis. The diagnosis was confirmed using the Vitek-2 system and the final determination for

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.

The plant growth-promoting rhizobacteria (PGPRBs) is an interesting way to promote increased vegetable production. Here, we aimed to isolate, identify, and characterize PGPRBs by using biochemical tests, sequencing of 16S ribossomal DNA, in vitro and screening for indoleacetic acid production. The isolates were identified through VITEK® 2 Compact equipment, which is an automated system. We identified microorganisms such as Alcaligenes faecalis sp. faecalis, Pseudomonas putida, Proteus vulgaris, Providencia rettgeri, Serratia marcescens e Myroides sp. by performing vitek 2 biochemical tests.

Abstract Different methodologies have been developed throughout the years to identify environmental microorganisms to improve bioremediation techniques, determine susceptibility profiles of bacteria in contaminated environments, and reduce the impact of microorganisms in ecosystems. Two methods of bacterial biochemical identification are compared and the susceptibility profile of bacteria, isolated from residential and industrial wastewater, is determined.

Bacteria are essential elements of natural environments. As bacteria are the key critical components of food webs and nutrient cycles, they contribute to ecosystem functioning via mutualists and pathogens for larger species. The present study has provided substantial grounds to confirm that microbial communities present in natural environments are much more diverse. Here, we tend to study a singular environment Lawachara National Park. Total 125 bacterial strains were isolated using serial dilution method.

The potential value of the chitin biomass (e.g. food waste) is recently considered being ignored by landfill. Chitin can be a potential cheap carbon source for converting into value-added chemicals by microorganisms. Serratia marcescens is a chitinolytic bacterium that harbors endogenous chitinase systems. With goals of characterzing S. marcescens chitinolytic capabilities and applying S. marcescens to chemical production from chitin, my dissertation main content includes five chapters: 1) Chapter 1 highlights background information of chitin source, S. marcescens and potential metabolic engin

Gram-negative pathogens are now a major concern for scientists worldwide due to their ability to cause a wide range of illnesses, from mild to severe, which can be fatal if not treated promptly. Their high resistance to antibiotics complicates the treatment process. Therefore, this chapter introduces the morphology, biochemical properties, virulence factors, typical diseases, treatments, and preventive measures for the 10 most significant Gram negative pathogens currently encountered in clinical settings, including: Acinetobacter baumannii, Citrobacter spp, Enterobacter spp, Escherichia coli,
