background: salmonella typhimurium is one of the most important species of salmonella that is intracellular parasite and attacks host mucus membrane. these bacteria can cause gastroenteritis, and their main transmission route is water, poultry, meat, egg, and raw food. the aim of this study was to detect three virulence genes associated with s. typhimurium named inva, stm4497, and flic183 genes...

objective botulism is the acute, descending, flaccid paralysis that results when the neurotoxin of clostridium botulinum blocks neuromuscular transmission. c botulinum toxin is the most poisonous substance that blocks neuromuscular transmission and causes death through airway and respiratory muscle paralysis; all forms of botulism manifest neurologically as asymmetric, descending, flaccid paral...

L. monocytogenes are facultative intracellular bacterial pathogens that cause food borne infections in humans. Very little is known about the gastrointestinal phase of listeriosis due to the lack of a small animal model that closely mimics human disease. This paper describes a novel mouse model for oral transmission of L. monocytogenes. Using this model, mice fed L. monocytogenes-contaminated b...

objective: due to the alarming increase the incidence and prevalence of infectious diseases and increasing bacterial resistance to antibiotics need to discover new strong antimicrobial compounds is feeling.methods: in this study, the antimicrobial properties of spider silk pholcus phalangioides produced in sterile conditions against two bacteria, listeria monocytogenes and esherichia coli with ...

background and objectives: recently, due to the interest of healthy lifestyle demand for research on novel methods of increasing the shelf-life of food products without the necessity of using preservatives has extended rapidly in the world. ability of nanoemulsions to improve global food quality has attracted great attention in food preservation. this is as a result of a number of attributes pe...

conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...

In a two year prospective survey of outbreaks of salmonella infection in hospitals in England and Wales 55 outbreaks were identified. Reports of investigation of these outbreaks were reviewed for evidence of food borne infection and cross infection. Food borne infection probably accounted for only six outbreaks, but these made up 40% of the 15 outbreaks in which there were more than five patien...
