The Different Types of Metallophores Produced by Salmonella enterica: A Review
Salmonella enterica (S. enterica) serovars Enteritidis and Typhimurium are the main causes of bacterial gastroenteritis worldwide. This Gram-negative rods bacterium possesses several virulence factors that enable it to survive the host’s nutritional immunity. Toxins and metallophores are among these factors. Heavy metals, in particular, are essential for the survival of all living organisms including bacteria. During infection, S. enterica competes with the host for the available heavy metals by secreting metallophores, which are secondary metabolites. Once produced in the extracellular medium, metallophores complex heavy metals thus allowing Salmonella to acquire metal ions through importing them via channels embedded in their membranes. This review highlights the biosynthesis, export, import, and genetic regulation of different metallophores synthesized by this germ.
期刊介绍：
Microbiology Research is an international, online-only, open access peer-reviewed journal which publishes original research, review articles, editorials, perspectives, case reports and brief reports to benefit researchers, microbiologists, physicians, veterinarians. Microbiology Research publishes ‘Clinic’ and ‘Research’ papers divided into two different skill and proficiency levels: ‘Junior’ and ‘Professional’. The aim of this four quadrant grid is to encourage younger researchers, physicians and veterinarians to submit their results even if their studies encompass just a limited set of observations or rely on basic statistical approach, yet upholding the customary sound approach of every scientific article.
