Yersinia enterocolitica Septicemia
Abstract:
Human Yersinia enterocolitica septicemia is an uncommon condition. Four new cases are reported here and a review is made of 51 others taken from medical literature. Septicemia caused by this microorganism occurs more frequently in the young and in the elderly, and usually involves patients havig previous liver or blood disorders, diabetes mellitus, and other debilitating diseases. Clinically it is indistinguishable from sepsis caused by other organisms of Enterobacteriaceae, but it is important that the clinician bear its existence in mind, since Yersinia enterocolitica strains are usually resistant to beta-lactam antibiotics, whereas they are susceptible to the aminoglycosides and co-trimoxazole, among others. Susceptibilities in the blood isolates from our patients, and in another ten fecal isolates from eight other patients showed the previously described pattern. Our isolates, however, were all susceptible to the new cephalosporins, cefamandole and cefoxitin, and to the experimental ones, HR-756, T-1551, and Ly-127.935.
Insights
Human Yersinia enterocolitica septicemia is rare, often affecting the young and elderly with underlying conditions. Antibiotic susceptibility patterns are crucial for effective treatment, with resistance to some drugs but sensitivity to others.
Area of Science:
- Infectious Diseases
- Microbiology
- Clinical Medicine
Background:
- Yersinia enterocolitica septicemia is an uncommon but serious infection.
- This condition disproportionately affects pediatric and geriatric populations.
- Pre-existing conditions like liver disease, diabetes, and immunosuppression increase risk.
Observation:
- Clinical presentation of Yersinia enterocolitica septicemia is often indistinguishable from other Enterobacteriaceae sepsis.
- A review of 51 cases from literature and four new cases were analyzed.
- Isolates were tested for antibiotic susceptibility.
Findings:
- Yersinia enterocolitica strains typically exhibit resistance to beta-lactam antibiotics.
- Sensitivity was observed with aminoglycosides and co-trimoxazole.
- Notably, isolates showed susceptibility to newer cephalosporins (cefamandole, cefoxitin) and experimental agents (HR-756, T-1551, Ly-127.935).
Implications:
- Awareness of Yersinia enterocolitica as a potential pathogen is critical for timely diagnosis.
- Understanding specific antibiotic resistance and susceptibility patterns guides effective therapeutic choices.
- Emerging cephalosporins and experimental antibiotics may offer alternative treatment options for Yersinia enterocolitica infections.
