Capnocytophaga canimorsus causes dog-bite wound induced sepsis in adults, but infection may follow mucous membrane exposure. Systemic infection in children is extremely rare. A neonate with frequent exposure to a family dog and no cutaneous infection developed C. canimorsus meningitis. Suspicion of this pathogen requires laboratory consultation. Parental counseling can limit the risk of pet acquired infections.

BACKGROUND The bacterial organism Capnocytophaga canimorsus is an oral commensal of cats and dogs and can cause life-threatening infections like mycotic aneurysm, meningitis, and sepsis. Mycotic aneurysms occur when microbial infections cause arterial wall degeneration. Difficulty in diagnosing Capnocytophaga canimorsus infection can occur due to the bacteria's fastidious nature and laboratory testing limitations, contributing to the infection's high morbidity and mortality.

The zoonotic pathogen is part of the oral microbiome of dogs and cats. We report the genome sequence of strain KM3195_24, isolated from a red fox. It has a circular genome of 2,718,701 bp with a G + C content of 36%, 2,419 CDS, 3 rRNA operons, and 45 tRNAs.

We discuss a case of meningitis caused by infection in a previously healthy elderly male who presented with altered mental status and new-onset seizures requiring intensive care. An open wound had served as an entry point for the infectious organism. After 25 days of treatment with meropenem, he recovered with persistent functional limitations and was discharged.

Introduction: Purpura fulminans is a rare but fatal manifestation of bacteremia that can present in immunocompromised hosts. This can have a profound impact on patients, including recipients of allogeneic hematopoietic stem cell transplant. Despite aggressive therapy, mortality can be as high as 60% and most patients require amputation of multiple extremities.
