BactoReal® Kit Listeria monocytogenes

Detection of the hlyA gene of Listteria monocytogenes.

Background: Listeria are ubiquitously found in soil and water. Listeriosis is an infection caused by the consumption of contaminated food (milk, cheeses, ice cream, vegetables, sausages, meats and fish). Although there are other types of Listeria (L. ivanovii, L. innocua, L. welshimeri, L. seegligeri and L. grayi), the culprit pathogen for most listeriosis cases is L. monocytogenes. Gastrointestinal symptoms may remain the only symptoms or precede more severe clinical manifestations such as sepsis and meningitis. People at risk include the elderly population, immunosuppressed patients and foetuses of pregnant women. L. monocytogenes is a Gram-positive, facultative anaerobic, and facultative intracellular bacterium with an incubation time of at least seven days. It expresses a Beta hemolysin (hlyA gene) which causes destruction of red blood cells and has the ability to target other cells. The ability of L. monocytogenes to grow at temperatures as low as 0°C permits multiplication in refrigerated foods. L. monocytogenes is killed by pasteurization and cooking.

Description: BactoReal® Kit Listeria monocytogenes uses real-time PCR for the detection of the hlyA gene of Listeria monocytogenes. Our carefully designed primers and probe ensure highest sensitivity and specificity. The kit consists of an assay mix for the detection of the pathogen as well as a positive control and an internal positive control (IPC). To minimize PCR cross-contamination, the reaction mix included contains dUTP and uracil-N glycosylase (UNG).
