متن کاملSurveying Contamination Rate of Local Lactic cheese with Escherichia coli, Staphylococcus aureus and Listeria monocytogenes in Gorgan in 2017
Background & Aim: Lactic cheese is traditionally produced from raw milk in some provinces of Iran. Therefore, presence of pathogenic bacteria in these cheeses can be dangerous to human health. The aim of this study was to evaluate the contamination rate of local lactic cheeses produced in Gorgan with Escherichia coli, Staphylococcus aureus and Listeria monocytogenes. Methods: Cheese samples we...
متن کاملefficiency assessment of simultaneous media to enrich listeria monocytogenes, staphylococcus aureus and enterohaemorrhagic escherichia coli
background and objective: due to low quantity of pathogens in foods, designing a broth medium to enrich simultaneously several pathogens through a suitable time to a detectable level is one of point of interest of many microbiologists. this study aimed to enrich simultaneously three food-borne pathogens (listeria monocytogenes, staphylococcus aureus and enterohaemorrhagic escherichia coli) tran...
متن کاملAssociation of agr Gene Expression with Staphylococcus Aureus Virulence Genes in BHI Broth
Abstract Background and Objective: Agr is the most important regulatory system for the expression of Staphylococcus aureus virulence factors in different conditions. Agr acts as a quorum sensing system in this bacterium which is activated by increased cell concentration during the transition from logarithmic growth phase to stationary phase. Its role is to up...
متن کاملTriclosan and antibiotic resistance in Staphylococcus aureus.
Triclosan (2,4,4'-trichloro-2'-hydroxydiphenyl ether) is an antimicrobial agent used in hygiene products, plastics and kitchenware, and for treating methicillin-resistant Staphylococcus aureus (MRSA) outbreaks. S. aureus strains with low-level resistance to triclosan have emerged. It has been claimed that strains with decreased susceptibility to biocides may also be less susceptible to antibiot...
