[Clostridium difficile-associated infections. How dangerous are the new strains?].
In recent years, a global increase of Clostridium difficile-associated infections (CDI) and the emergence of new hypervirulent strains causing numerous outbreaks was noticed. The appearance of these strains was accompanied by increased morbidity and mortality, affecting patients previously unknown to be at risk for CDI. Meanwhile, these hypervirulent strains occur in Germany as well. So far, the changing epidemiology of CDI did neither change diagnosis nor therapy of CDI but necessitates a series of preventive measures like the surveillance of CDI and contact precautions while caring for affected patients. If there are complicated or severe cases of CDI, the hypervirulent strains should be suspected and stool culture for isolation of C. difficile should be aimed.
