The Bacteroides and Parabacteroides species are important obligate anaerobic bacteria that are significant constituents of normal flora (microbiota), and opportunistic pathogens with special biological background. They are highly resistant to antibiotics and monitoring their resistance levels is important for their empiric therapy. Several antibiotic resistance studies were conducted in the USA and Europe and we have data for the region involved in this study showing comparable trends. Multidrug-resistant strains are emerging among Bacteroides too, where the proper antibiotic tests and treatments may be life-saving.
