TEM-1 is the dominat β-lactamase of Haemophilus influenzae and can be located on small plasmids. Three distinct plasmids from 4,304 to 5,646 nt were characterized: pA1606, pA1209 and pPN223. In addition to TEM-1 and a replication enzyme of the Rep 3 superfamily, pA1606 encodes a Tn3 resolvase gene and pA1606 and pA1209 encode an ORF similar to a plasmid recombination enzyme gene described in Gram-positive bacteria. The plasmids transformed strain Rd to the ampicillin-resistant phenotype.
