Resistance to cephalosporin antibiotics can involve either reduced affinity of existing PBP components or the acquisition of a supplementary β-lactam-insensitive PBP. Currently, some "Citrobacter freundii, Enterobacter cloacae", "Neisseria gonorrhoeae", and "Escherichia coli" strains are resistant to cephalosporins. Some "Morganella morganii", "Proteus vulgaris, Providencia rettgeri, Pseudomonas aeruginosa", and "Serratia marcescens" strains have also developed resistance to cephalosporins to varying degrees.
