Bacteremia due to Pasteurella dagmatis acquired from a dog bite, with a review of systemic infections and challenges in laboratory identification

Abstract

Pasteurella dagmatis, a Gram-negative coccobacillus, has been isolated from both dogs and cats as normal flora. It is also a fairly new species for many clinicians because it is a pathogen in human infections. The authors present a case of bacteremia in a 74-year-old man that was caused by P dagmatis. A comparison of other reported cases of bacteremia due to P dagmatis is provided, along with a discussion of the challenges of standard automatic identification including alternative methodologies.
