Capnocytophaga canimorsus is a Gram-negative bacilli that is part of the normal oral flora of dogs and some cats; it is well known to cause septicemia and endocarditis after their bite. This is the first reported case of infective endocarditis affecting both native mitral and aortic valves after a lion bite in a patient with heavy ethanol consumption, who ultimately died after valve replacements.
