title: A general ampC active site oligonucleotide probe for gram-negative rods.
abstract: We have developed a 33 mer probe that hybridizes to the serine active site of the chromosomal ampC beta-lactamase gene of Pseudomonas aeruginosa and the Enterobacteriaceae. We tested this probe against a variety of Enterobacteriaceae, and a series of 23 P. aeruginosa by dot-blots and selected Southern blots. This probe is an alternative or supplement to enzyme studies for characterizing the class of a Gram-negative rod's beta-lactamase and is a useful tool for studies of Pseudomonas beta-lactamase regulation.
