Caplan, Linda M. (Kantor), Dobson, Margaret L., and Dorkin, Henry: Yersinia enterocolitica septicemia. Am J Clin Pathol 69: 189–192, 1978. Yersinia enterocolitica was recovered from the blood of an infant with sepsis and fever but with few gastrointestinal symptoms. The age of this patient was unusual as septicemia owing to this organism has most frequently been seen in adults. Because of the absence of digestive symptoms, it is uncertain what the portal of entry of the organism might have been. Yersinia enterocolitica is not often recognized, either because of difficulties in identification or because it may not be recognized as a human pathogen.
