| isolation of pasteurella aerogenes from the uterus of a rabbit following abortion. | pasteurella aerogenes was isolated from the uterus and peritoneal cavity of a rabbit which died 4 days after abortion. histopathologic observations confirmed a bacterial infection. mouse pathogenicity tests indicated that this organism was an opportunistic pathogen that might have been responsible for the stillbirths. the cultural and biochemical characteristics of this isolate were similar to those of the pasteurella aerogenes isolated from swine. this is the first report describing the isolati ... | 1978 | 703252 |
| abortion of a sow caused by pasteurella aerogenes. | three strains of the pasteurella aerogenes complex were isolated as sole pathogens from aborted fetuses of a sow aborted at the 12th week of gestation on a farm of 600 sows. gross pathology showed no characteristic lesions. the isolates were biochemically identical and resembled p. pneumotropica on the basis of their strong indole and urease positivity but they produced gas, were ornithine decarboxylase negative and fermented mannitol but not trehalose. only a few differences were apparent in bi ... | 1991 | 1750360 |
| characterization of paxa and its operon: a cohemolytic rtx toxin determinant from pathogenic pasteurella aerogenes. | pasteurella aerogenes is known as a commensal bacterium or as an opportunistic pathogen, as well as a primary pathogen found to be involved in abortion cases of humans, swine, and other mammals. using broad-range dna probes for bacterial rtx toxin genes, we cloned and subsequently sequenced a new operon named paxcabd encoding the rtx toxin paxa in p. aerogenes. the pax operon is organized analogous to the classical rtx operons containing the activator gene paxc upstream of the structural toxin g ... | 2000 | 10603361 |
