Genetic determinant of the ROB-1 beta-lactamase in bovine and porcine Pasteurella strains.
The ROB-1 beta-lactamase, previously described in Haemophilus influenzae, has been found in the genus Pasteurella. In three bovine strains of Pasteurella multocida and Pasteurella haemolytica, ROB-1 production was determined by plasmids of 4.4 kilobases. In one porcine strain of Pasteurella aerogenes, the enzyme seems to be chromosomally encoded.
