Abstract:   (818 Views)
Listeria monocytogenes has been the subject of numerous studies due to its tolerance in cold temperatures, microaerophilic and mobile nature, high salt tolerance, and causing abortion in pregnant women. Due to the presence of the virulence gene in the heat-dependent chromosome, it becomes more severe when growing in the refrigerator. It has received assiduous attention and research due to its resistance to the low limit of pasteurization temperature (7200C), listeriolysin O production, intracellular invasion power and resistance in phagocytosis, the ability to carry out hemolysin β, and wide distribution in food. The prevalence of monocytogenes contamination in raw milk in Amol is 35%, and in local butter, it is 10%. In Isfahan, the prevalence rates of monocytogenes contamination are 19.7% in raw milk and traditional products, 19.4% in ice cream, 11.0% in cream, and 4% in porridge. In Marvdasht, it is 13.8% in cheese. In Qazvin, the prevalence rates are 10.9% and 7% in traditional and white cheeses, respectively. In Marvdasht, the highest antibiotic resistance of raw milk was against tetracycline and ceftriaxone. In Amol, the highest antibiotic resistance of raw milk was against ampicillin (87.7%) and tetracycline (71.4%), and the highest antibiotic resistance of local butter was to erythromycin (100% resistant) and ampicillin (100% semi-resistant). The prevalence of Listeria monocytogenes in Tehran, Isfahan, Chaharmahal-Bakhtiari, and Fars (Shiraz) provinces has been reported between 1.1 and 40% in different years. Therefore, this study was conducted taking into account the increasing prevalence of monocytogenes in foods of animal origin and the substantial risk of an epidemic disease.
