[Nosocomial transmission of listeriosis].

Listeriosis is a severe and possibly fatal disease. Its incidence in the Czech Republic is low, with the most common vehicles of transmission being cheese, pastes, meat products, and salads. Nosocomial transmission is rare in the Czech Republic. Phylogenetic analysis and genotyping of isolated Listeria strains are very helpful in identifying the source of infection. A careful adherence to the preventive anti-epidemic measures in the health care institutions is still critically important.
