The<unk> s are a group of antibiotics that have the widest antibacterial<unk>  of all<unk> s. Some sources identify them with antipseudomonal<unk> s, others consider these types to be distinct. This group includes the carboxypenicillins and the ureidopenicillins. Aminopenicillins, in contrast, do not have activity against Pseudomonas species, as their positively charged amino group does not hinder degradation by bacterially produced beta-lactamases.
