Pathogenic bacteria

PI: PD Dr. Sabine Gronow

Pathogenic bacteria are of major interest for many research projects as well as for standard applications. Not only Type strains of a large variety of species are available in this part of the collection but also rather extensive groups of strains for selected species.
Research is centered on comparative analyses to describe newly found pathogens of yet unknown species. Here, the large diversity of Type strains already present in the collection provides the background for comprehensive studies.
On larger collections of isolates of one species but from different sources we carry out studies such as antibiotic susceptibility tests or PCR reactions to check for specific genes (e.g. toxins, resistance factors). Isolates from clinical collections are used to perform population genomics and epidemiological studies. Especially multiresistant strains are important as targets for studies involving new potential antimicrobial substances or bacteriophages.
Additionally, the Pathogen Repository of the German Center for Infection Research (DZIF) is hosted by the DSMZ and is closely collaborating with the collection of pathogenic bacteria.
