It appeared initially in a limited number of bacterial species (E. cloacae, C. freundii, S. marcescens, and P. aeruginosa) that could mutate to hyperproduce their chromosomal class C β-lactamase. A few years later, resistance appeared in bacterial species not naturally producing AmpC enzymes (K. pneumoniae, Salmonella spp., P. mir… chinese takeaway bargoed
