in recent years due to changes in lifestyle and eating behavior of the human populations, disease caused by contaminated food has increased significantly. listeria monocytogenes, escherichia coli o157:h7 and salmonella enteric are three of the most important food borne bacterial pathogens and can lead to food borne diseases. also today wide spread of resistance to antibiotics among bacteria occ...

background :  a large number of plants are used for treatment of diseases because of their antimicrobial activities. this study aims to investigate the antimicrobial effects of some plants on the food pathogenic bacteria.   methods : plant extracts were obtained using the rotary system, the minimum inhibitory concentration (mic) by diluting method against bacteria was determined.   results :   ...

The present study was carried out to compare the inhibitory effect of alginate coatings containing Zataria Multiflora Boiss essential oil (ZMEO) in two forms of coarse emulsion and Nano-emulsion on the growth of inoculated Escherichia coli O157:H7in beef fillet during 16 days of refrigeration (4 C °). Accordingly, alginate solutions (3%) with different co...

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...

Background: Food-born botulism is caused by ingestion of contaminated food with clostridium botulinum neurotoxin. Case: In food-born botulism, due to acetylcholine release blockade, neuromuscular signs and symptoms are common, but in this case report we present a food-born botulism with papiledema and venous sinus thrombosis. Conclusion: Papiledema and fever could not rule out the diagnosis...

The general ecological mechanism that provides species survival and multiplication in a previously unfamiliar environment and is known as pre adaptation appears to be involved in the phenomenon of emerging infections [7]. Living in their natural environment, causative agents of emerging infections might be wild mammal pathogens or be carried asymptomatically by wild animals or be rather microbi...

BACKGROUND One of the most important items in molecular characterization of food-borne pathogens is high quality genomic DNA. In this study, we investigated three protocols and compared their simplicity, duration and costs for extracting genomic DNA from Linguatula serrata. METHODS The larvae were collected from the sheep's visceral organs from the Yazd Slaughterhouse during May 2013. DNA ext...
