Fatal salmonellosis originating in a clinical microbiology laboratory
Abstract:
Laboratory-acquired infections concern all microbiologists. During ongoing surveillance of laboratory-acquired enteric infections, salmonella infections in the wife and son of a laboratory worker were documented; the first case was fatal. Neither patient had had any contact with the laboratory. The infecting organisms were Salmonella typhi and a multiply resistant strain of Salmonella agona that were being worked within the laboratory; both strains had been received 1 to 2 years previously for proficiency testing exercises. This report documents the transmission of enteric pathogens beyond the confines of the laboratory, with its tragic outcome, and suggests measures to prevent the recurrence of this problem.
Insights
Laboratory-acquired Salmonella infections spread to a microbiologist's family, causing a fatality. This highlights the risk of enteric pathogen transmission outside the lab and the need for enhanced safety measures.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Laboratory-acquired infections pose a significant risk to microbiologists.
- Surveillance of enteric infections is crucial for understanding disease transmission.
Observation:
- Salmonella infections were diagnosed in the wife and son of a laboratory worker.
- Neither family member had direct contact with the laboratory environment.
Findings:
- The infecting strains were Salmonella typhi and a multidrug-resistant Salmonella agona.
- These strains were previously used in proficiency testing exercises within the laboratory.
Implications:
- Enteric pathogens can transmit beyond the laboratory, leading to severe outcomes, including fatalities.
- This case underscores the necessity for stringent safety protocols to prevent external pathogen spread.
