Isolation of Listeria monocytogenes from Meat and Dairy Products
Introduction: This study was intended to determine the presence and distribution of Listeria monocytogenes in various meat and dairy products from Qazvin Province by culture followed by biochemical and morphological assays. The identity of the isolates was further obtained by amplification of prfA gene in bacteria isolates. This gene is a transcriptional activator of virulence gene ex...

This microorganism can be found in several processed foods, dairy products, raw milk, meat and fish products, seafoods, eggs, fruits, and vegetables. This review discusses about the epidemiologica...
متن کاملThermotolerance of heat-shocked Listeria monocytogenes in milk exposed to high-temperature, short-time pasteurization.
The effect of prior heat shock (48 degrees C for 15 min) on the thermotolerance of Listeria monocytogenes at the minimal high-temperature, short-time (71.7 degrees C for 15 s) parameters required by the Pasteurized Milk Ordinance was examined. The mean D71.7 degrees C value for heat-shocked L. monocytogenes was 4.6 +/- 0.5 s (control D = 3.0 +/- 1.0 s); the ratio of D to control D was 1.5. The ...
متن کاملListeria monocytogenes Contamination in Unpasteurized Traditional Cheese Products in Qazvin, Iran
Background and purpose: Listeria monocytogenes is a foodborne pathogen and a pothential risk to public health. Listeriosis is one of the most serious infectious diseases in most developed countries. Consumption of raw milk and unpasteurized traditional dairy products such as cheese can be a major reason for listeriosis in humans. This reaserch aimed at investigating Listeria monocytogenes conta...
