Pasteurella dagmatis: une cause inhabituelle de spondylodiscite

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

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.

A case of bacteremia in a 74-year-old man, which was caused by Pasteurella dagmatis and complicated by thrombocytopenia, is presented. Microorganism identification was performed by the provincial reference laboratory using traditional biochemical profiling, completmented with both the sequencing of the 16S ribosomal RNA gene and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry; antibiotic-susceptibility testing was also performed. After treatment with the appropriate antibiotics, the patient fully recovered. Systemic infections attributed to this organism are rarely reported in the literature. Other reported cases of bacteremia due to P dagmatis are reviewed and compared with the present case. The challenges of relying on standard automatic identification are discussed, with alternative methodologies provided.

Prosthetic valve endocarditis caused by a Pasteurella dagmatis-like isolate originating from a patient's cat

Pasteurella species are part of the oral flora of cats and dogs. In humans, they are frequently found in infected animal bite wounds, but invasive infections are rare. This is the first report of prosthetic-valve endocarditis with a Pasteurella dagmatis-like species, which originated from the patient's cat.

Pasteurella abscess in tibial regenerate bone: a case report

Although superficial pin tract infections during limb lengthening are extremely common, most settle spontaneously or with antibiotics. In contrast, deep infection around pin tracts leading to osteomyelitis and abscess formation is much less frequently observed and may need washout and curettage. We report a case of a 10-year-old boy who presented with latent abscess formation at a tibial lengthening site because of Pasteurella, a rare bacterial cause of infection usually associated with animals. To our knowledge, this is the first reported case of abscess formation within regenerate bone associated with this organism and its late presentation in previously well-healed bone is surprising.
