Yersinia enterocolitica septicemia
Insights
Yersinia enterocolitica caused sepsis in an infant, which is unusual given the patient's age. The lack of typical gastrointestinal symptoms made identifying the infection source challenging.
Area of Science:
- Medical microbiology
- Pediatric infectious diseases
- Bacteriology
Background:
- Yersinia enterocolitica is a bacterial pathogen that can cause various infections.
- Septicemia, or sepsis, is a life-threatening condition caused by the body's response to infection.
- Gastrointestinal symptoms are commonly associated with Yersinia enterocolitica infections.
Observation:
- A case of Yersinia enterocolitica sepsis in an infant is presented.
- The infant exhibited fever and sepsis but minimal gastrointestinal symptoms.
- This presentation is atypical, as Yersinia enterocolitica septicemia is more common in adults.
Findings:
- Yersinia enterocolitica was successfully isolated from the infant's blood.
- The organism's presence in an infant without significant digestive symptoms was noted.
- The portal of entry for the bacteria could not be definitively determined due to the atypical presentation.
Implications:
- This case highlights the potential for Yersinia enterocolitica to cause sepsis in infants, even without typical symptoms.
- It underscores the importance of considering Yersinia enterocolitica in pediatric sepsis, especially when gastrointestinal signs are absent.
- Challenges in identifying Yersinia enterocolitica may contribute to underdiagnosis in both pediatric and adult populations.
Abstract:
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.
