Abstract
Intrageneric and intergeneric conjugational transfer of .beta.-lactamase production to a B. catarrhalis recipient is described. The branhamella donor strains were fresh isolates subcultured onto penicillin-containing media directly from the primary plates. A .beta.-lactamase positive Moraxella nonliquefaciens served as donor in the intergeneric matings. The substrate profiles of the branhamella and moraxella enzymes were indistinguishable as determined by biological assays. Excessive endonuclease activity did not permit a conclusive characterization of isolated extrachromosomal DNA from the branhamella donors.This publication has 3 references indexed in Scilit:
