Immune Thrombocytopenic Purpura Associated With Capnocytophaga Bacteremia

Capnocytophaga canimorsus is a gram-negative, capnophilic bacillus commonly found in the oral flora of healthy dogs and cats. C canimorsus can be transmitted to humans via animal bites, scratches, or close contact. Previously, severe C canimorsus sepsis has been associated with thrombotic microangio...

description Capnocytophaga canimorsus is a gram-negative, capnophilic bacillus commonly found in the oral flora of healthy dogs and cats. C canimorsus can be transmitted to humans via animal bites, scratches, or close contact. Previously, severe C canimorsus sepsis has been associated with thrombotic microangiopathies, such as hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, and disseminated intravascular coagulation. We present here a novel case of secondary immune thrombocytopenia caused by C canimorsus bacteremia following a dog bite to underscore the importance of a thorough history in patients presenting with severe, unexplained thrombocytopenia.
