Yersinia Enterocolitica Sepsis in an Elderly Male With No Iron Overload: A Case Report From the Northeastern United States

Yersinia enterocolitica (YE) is a facultative anaerobic gram-negative coccobacillus of the genus Yersinia (the most common ones are YE serogroups O:3; O:5,27; O:8; and O:9). Its incubation period is typically 1-14 days. The symptoms of YE infection include fever, abdominal pain (which may mimic appendicitis), and diarrhea (which may be bloody and can persist for several weeks). It is most commonly reported in infants and children due to cross-contamination of their feeds and pacifiers by people handling pork products, especially while cooking chitterlings. Necrotizing enterocolitis has been described in infants following YE infections. Adults who are immunocompromised or in an iron-overload state can develop sepsis with YE infection, which has a high fatality rate. Post-infectious sequelae like reactive arthritis and erythema nodosum can occur in certain HLA types. The diagnosis is made by isolating the organism from the body fluids, stool. The gastrointestinal (GI) pathogen panel by polymerase chain reaction (PCR) is helpful in making an early diagnosis. In this report, we discuss a case of an elderly male from a nursing facility who presented with abdominal pain, vomiting, GI bleeding, and sepsis. He required a brief ICU stay and pressor support. GI pathogen panel was instrumental in the early diagnosis of YE. This condition is not often reported in the Northeastern US. Using GI pathogen PCR testing will lead to the detection of more cases of YE in geographical regions where it was not considered prevalent.
