Bacteroides: the Good, the Bad, and the Nitty-Gritty

Bacteroides: the Good, the Bad, and the Nitty-Gritty

The most common mechanism of resistance to β-lactam agents is β-lactamase (product of the cepA gene), a chromosomally encoded class 2e cephalosporinase , which is found in nearly all Bacteroides species . This enzyme is inhibited by the most commonly used β-lactamase inhibitors (sulbactam, clavulanic acid, and tazobactam), and agents ...

Staphylococci are somewhat heat resistant and can survive dry conditions. Their high salt tolerance enables strains to grow in salt-preserved foods and causes cases of food poisoning. Staphylococci, however, cannot resist temperatures as high as 55 °C for long periods, and they are not bile resistant. Most species are sensitive to novobiocin.

Clostridium botulinum spores are highly resistant to thermal destruction at water activities between 0.2 and 0.4 (dry heat) and are much less resistant to heat at water activities above this range. This finding may be practical for high temperature-short time dry heat sterilization (National Canners Association, 1976a).
