[Yersinia enterocolitica septicemia occurring in a hospital milieu. A case with septic shock in an immunocompromised patient].

A case of Yersinia enterocolitica septicemia is reported. This case is unusual as the infection was apparently acquired within the hospital and septic shock occurred during the course. Immunodeficiency, which is nearly consistent in similar observations and was established in the index case, was apparently caused by protein-calorie deficiency, without any of the usual associations reported in the literature.
