Laboratory of Bacteriology

Otto Research Group

The Pathogen Molecular Genetics section investigates physiology and host interaction of Gram-positive pathogens with a focus on Staphylococcus aureus and coagulase-negative staphylococci. We are also investigating the interactions of commensal staphylococci with other bacteria within the human microbiome and the potential of probiotic approaches to control bacterial infections.
