Abstract
In Norway the Norwegian Institute of Public Health (NIPH) is the primary facility for nationwide surveillance of foodborne infections, and it is vital that we can perform rapid and high resolution identification of foodborne bacteria at the strain level. During the last decade a rapid introduction of DNA-based methods has been introduced, which show promise in enhancing the speed and discriminatory capability of the typing laboratory. The laboratory responsible for genotyping enteropathogens at NIPH is limited in staff, thus methods demanding reduced labour, high degree of automation and increased ease of interpretation is essential. We found that this could be achieved by focusing on MLVA for some of the most predominant enteropathogenic species. Bacterial genotyping is performed by several laboratories in Norway, however this review will address the use of routine genotyping by MLVA of common foodborne bacteria at NIPH. The emphasis will be on Escherichia coli, Salmonella typhimurium, Shigella spp. Yersinia enterocolitica and Listeria monocytogenes. This review is based on an oral presentation given at the 9th International Meeting on Microbial Epidemiological Markers in Wernigerode Germany on September 1st 2010.
