Yersinia enterocolitica in Oneida County, New York
Contributions to Microbiology and Immunology
|January 1, 1979
Summary
Yersinia enterocolitica, a cause of Yersiniosis, was prevalent in New York State, found in human, animal, water, and milk samples. The outbreak strain was primarily serotype 0:8.
Area of Science:
- Microbiology
- Infectious Diseases
- Environmental Health
Background:
- Yersiniosis outbreaks necessitate understanding the prevalence and sources of Yersinia enterocolitica.
- Previous studies have indicated Yersinia enterocolitica's presence in various environmental and food sources.
Purpose of the Study:
- To investigate the prevalence of Yersinia enterocolitica during and after a Yersiniosis outbreak in Oneida, N.Y.
- To characterize the isolates, including serotyping and biotyping, to understand transmission dynamics.
Main Methods:
- Collected and analyzed 963 specimens over 7 months, including human, animal, water, and milk samples.
- Identified and isolated Yersinia enterocolitica using standard microbiological techniques.
- Performed serotyping and biotyping on recovered isolates.
Main Results:
- 103 Yersinia enterocolitica isolates were recovered, with 91 from Oneida County.
- 62 isolates (60.2%) were from human sources, 52 from Oneida County.
- Outbreak isolates were mainly serotype 0:8 (Niléhn type 2, Wauters type 1, Knapp and Thal type 2); other isolates showed diverse serotypes and biotypes.
- Yersinia enterocolitica was found in 10-25% of environmental/food specimens and 2.3% of stool specimens.
Conclusions:
- Yersinia enterocolitica appears ubiquitous in New York State, with diverse sources contributing to its presence.
- The study highlights the potential for Yersinia enterocolitica transmission from various environmental reservoirs to humans.
- Understanding the epidemiology of Yersinia enterocolitica is crucial for preventing future outbreaks.
