Prevalence of Listeria monocytogenes in raw milk in Kerman, Iran
Listeria monocytogenes as one of the most important pathogen in public health concerns is transmitted through consumption of contaminated food. The pathogen has been considered as a potential source of contamination of raw milk and dairy products. This research was aimed to investigate prevalence of L. monocytogenes in raw milk in Kerman region. In the summer of 2011, a total ...
متن کاملDairy farm reservoir of Listeria monocytogenes sporadic and epidemic strains.
Identifying the reservoirs of a pathogen is vital for control of sporadic disease and epidemics. Listeria monocytogenes is a zoonotic foodborne pathogen that is responsible for 28% of food-related deaths in the United States annually, as well as a major cause of massive product recalls worldwide. To examine the role of the dairy farm as a potential source or reservoir for L. monocytogenes subty...
متن کاملRestriction enzyme analysis of Listeria monocytogenes strains associated with food-borne epidemics.
Listeria monocytogenes (serotype 4b) has caused four major food-borne epidemics in North America. In this study, L. monocytogenes isolates from the Nova Scotia (Canada), Boston (Mass.), and Los Angeles (Calif.) outbreaks were examined by restriction enzyme analysis with the endonuclease HhaI. Human isolates (n = 32) from the 1981 Canadian outbreak were compared with a strain recovered from cole...
متن کاملIsolation, Identification and Antibiotic Resistance Profile of Listeria Monocytogenes Strains in Red Meats
Abstract Background and Objective: Listeria monocytogenes is a bacterium transferred by foods and is the agent of many sporadic and epidemic diseases in humans. This study aimed to investigate the prevalence of L. monocytogenes and to determinine their antibiotic resistance profile in red meats. Material and Methods: this cross-sectional study was performed on 400 red meat samples o...
متن کاملHost-mediated modification of PvuII restriction in Mycobacterium tuberculosis.
Restriction endonuclease PvuII plays a central role in restriction fragment length polymorphism analysis of Mycobacterium tuberculosis complex isolates with IS6110 as a genetic marker. We have investigated the basis for an apparent dichotomy in PvuII restriction fragment pattersn observed among strains of the M. tuberculosis complex. The chromosomal regions of two modified PvuII restriction sit...
