The investigation of molecular characterization of presumptive Listeria monocytogenes isolates from a food-processing environment
Background: Listeria is a Gram-positive, non-spore forming, facultative anaerobic intracellular bacterium. The most important pathogens in mammals include Listeria monocytogenes and Listeria ivanovii. The former generally causes disease and death in both humans and animals while the latter performs sporadically and primarily causes illness in ruminant...

متن کاملResistance of Listeria monocytogenes biofilms to sanitizing agents in a simulated food processing environment.
The objective of this study was to evaluate the resistance of biofilms of Listeria monocytogenes to sanitizing agents under laboratory conditions simulating a food processing environment. Biofilms were initially formed on stainless steel and Teflon coupons using a five-strain mixture of L. monocytogenes. The coupons were then subjected to repeated 24-h daily cycles. Each cycle consisted of thre...
متن کاملRapid Detection of Listeria monocytogenes in Food and Food Animals
The objective of this study was to streamline the detection and identification of Listeria monocytogenes (LM) in livestock and foods. Hog tonsil scrapings, hog tissues collected at necropsy, ground pork, and turkey washes were inoculated into UVM-1 (10% w/v) and after incubation (3 days) transferred to UVM-2. After 2 days, samples were plated to Palcam agar and incubated (48 h, 37 o C). Charact...
متن کاملCharacterization of Listeria monocytogenes from food and food-related settings
Listeriosis is a serious public health concern due to its high fatality rates. The present investigation screened for the occurrence of Listeria monocytogenes in food and food-related environments by analyzing samples from a cheese making factory, a slaughterhouse and a supermarket. Among the eighty-seven samples analyzed, thirty-four isolates were recovered and subsequently evaluated regarding...
