Vertebral osteomyelitis due to Pasteurella aerogenes.

A case of C6-C7 vertebral osteomyelitis due to Pasteurella aerogenes in a previously healthy 62-y-old man in the absence of any history of animal exposure, debilitating disease or immunosuppression is reported. Culture testing of biopsy samples of the vertebral body using the panels and database of the BBL Crystal enteric/non-fermenter system revealed that the infecting bacterium was P. aerogenes. Treatment with cloxacillin and gentamicin was followed by resolution of bone infection on serial follow-up magnetic resonance imaging scans. Pasteurellae are primarily animal pathogens but are capable of producing a variety of local and systemic diseases in humans.

[Mycotic anuerysm secondary to bacterial endocarditis. Review apropos of a case]. / Anuerisma micótico secundario a endocarditis bacteriana. Revisión a propósito de un caso.

A case is presented of Subacute Bacterial Endocarditis on a biological Duramater Prosthesis. In the evolution curse, the patient presented an intraparenchimal cerebral haemorrhage, where--upon the angiographic studies demonstrated the existence of a mycotic aneurysm in the left median cerebral arterial territory. With specific antibiotic therapy and replacement of the prosthesis, the clinical evolution of the case, was positive, and later angiographies evidenced the disappearance of the aneurysm. The incidence of intracranial mycotic aneurysm complicating bacterial endocarditis is relatively high (up to 4% in post-mortem series). There have been very few cases communicated up to now with angiographic demonstration. Mortality is similar in patients under surgical or medical treatment. The aetipothogenic aspects are discussed, as well as the recommended therapeutic measures.
