Although the presence of beta-lactamases has been shown to lower the MICs for certain beta-lactams in Campylobacter spp., campylobacters are generally considered intrinsically resistant to many agents in this group and beta-lactams are not recommended in the treatment of campylobacteriosis (Aarestrup and Engberg, 2001; Griggs et al., 2009; Wieczorek and Osek, 2013). This evidence concerns the gene LACTB and campylobacteriosis.
