Thrombotic microangiopathy secondary to Capnocytophaga canimorsus bacteremia

Abstract

Capnocytophaga canimorsus is an Anaerobic Gram-Negative bacterium present in the oral microbiology of cats and dogs. It can produce infections in humans, being capable of causing severe complications with the development of septic shock. There are known cases where this bacterium developed medical complications like thrombotic microangiopathy and disseminated intravascular coagulation. We have the case of 79 years old male that developed thrombotic microangiopathy and splenic infarction linked to bacteraemia by Capnocytophaga canimorsus. Due to its severity, it was necessary to start renal replacement therapy and several sessions of plasmapheresis with good evolution.
