Sequences of CAZ-3 and CTX-2 extended-spectrum beta-lactamase genes.
The nucleotide sequences of blaTEM genes coding for the extended-spectrum beta-lactamases CAZ-3 and CTX-2 were determined. The gene for CAZ-3 is identical to blaTEM-12b. The gene for CTX-2 differs from characterized blaTEM genes for extended-spectrum beta-lactamases by a new combination of already known mutations. We propose for CTX-2 the designation TEM-25.
