The investigation of molecular characterization of presumptive Listeria monocytogenes isolates from a food-processing environment.

ABSTRACT:

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 ruminants.

Aims

The aim of this project was to use conventional and molecular techniques to determine whether the provided samples were L. monocytogenes, and whether they were genetically similar or different.

Methods

The provided presumptive Listeria cultures isolated from industrial processed food are conventionally assumed to be L. monocytogenes. All samples were cultured on brain heart
