Biofilm Formation of Salmonella
نویسنده
چکیده
Salmonella spp. may form biofilm, and bacteria in biofilm are more resistant to drug, chemical, physical and mechanical stresses, and host immune system. The progress on biofilm research will be helpful for the development of new tools and strategies to prevent biofilm-related disease and decontaminate biofilm-derived Salmonella in food produc‐ tion. In this review, we present a comprehensive overview of biofilm formation in Salmonella, included that (1) the component of Salmonella biofilm, (2) the detection methods for biofilm, (3) the identification of biofilm-formation-associated genes, (4) the regula‐ tion mechanism of biofilm formation, and (5) virulence or resistance of Salmonella in biofilm.

Bacterial Biofilm Formation in Milking Equipments in Lilongwe, Malawi
Background: Some microorganisms can adhere to food handling surfaces forming biofilms that pose a safety challenge. This study was done to evaluate bacterial biofilm formation in milking equipments in Lilongwe, Malawi. Methods: Pooled milk (n=54) and water (n=60) samples were collected from households and milk bulking groups in Lilongwe, Malawi. Swabbing (n=46) and rinsing (n=16) were done on ...

متن کاملEffect of Food Residues in Biofilm Formation on Stainless Steel and Polystyrene Surfaces by Salmonella enterica Strains Isolated from Poultry Houses
Salmonella spp. is a major food-borne pathogen around the world. The ability of Salmonella to produce biofilm is one of the main obstacles in reducing the prevalence of these bacteria in the food chain. Most of Salmonella biofilm studies found in the literature used laboratory growth media. However, in the food chain, food residues are the principal source of nutrients of Salmonella. In this st...
متن کاملNutrient Composition Promotes Switching between Pellicle and Bottom Biofilm in Salmonella
Salmonella is one of the most frequently reported causes of foodborne illness worldwide. Non-typhoidal serovars cause gastroenteritis in humans. Salmonella can grow on surfaces forming biofilms, contributing to its persistence since biofilms are difficult to eradicate due to the high resistance to antimicrobials and disinfectants. It has been described that there are two crucial biofilm promoti...
متن کاملBiofilm formation by Salmonella enterica serovar Typhimurium and Escherichia coli on epithelial cells following mixed inoculations.
Biofilms were formed by inoculations of Salmonella enterica serovar Typhimurium and Escherichia coli on HEp-2 cells. Inoculations of S. enterica serovar Typhimurium and E. coli resulted in the formation of an extensive biofilm of S. enterica serovar Typhimurium. In experiments where an E. coli biofilm was first formed followed by challenge with S. enterica serovar Typhimurium, there was signifi...
