  • a For the blaTEM genes, 10 = TEM-10-type (amino acid changes R164S and E240K), 12 = TEM-12-type (amino acid change R164S), 26 = TEM-26-type (amino acid changes E104K and R164S), and 63 = TEM-63-type (amino acid changes E104K, R164S, and M182T). For the blaSHV genes, 2 = SHV-2-type (amino acid change G238S), and 5 = SHV-5 (amino acid changes G238S and E240K). *, blaSHV-1 with silent nucleotide change from reported sequence at amino acid 240 (Glu240, GAG to GAA); §, SHV-2-type with a silent mutation at 240 (Glu240, GAG to GAA); 5^, SHV-5-type with nucleotide change from reported sequence at amino acid 240 (Glu240Lys, AAG to AAA); +, presence of PER-1β -lactamase. For the blaCTX-M genes, 2= CTX-M-2-type and 3 = CTX-M-3-type.

  • b Denotes genes not fully sequenced (see the text).
