Detection of staphylococcal enterotoxigenicity. II. Field strains
Journal of Hygiene, Epidemiology, Microbiology, and Immunology
|January 1, 1980
Abstract:
The immunodiffusion micromethod was used to detect enterotoxin production in 5974 staphylococcal strains isolated during 1972-1978 from food, human milk and various specimens of clincial material. Of a total number of examined strain there were identified 3001 staphylococcal strains that produced the following enterotoxins or enterotoxin combinations: A, B, C, D, E, A + B, A + C, A + D, A + E, B + D, C + E and A + C + E.
Insights
Researchers detected enterotoxin production in 3001 staphylococcal strains using immunodiffusion. These strains, isolated from food and clinical sources, produced various staphylococcal enterotoxins and combinations.
Area of Science:
- Microbiology
- Food Safety
- Clinical Diagnostics
Background:
- Staphylococcal enterotoxins are a significant cause of foodborne illness.
- Accurate detection of enterotoxin-producing strains is crucial for public health.
- Previous methods for enterotoxin detection were less efficient.
Purpose of the Study:
- To determine the prevalence of enterotoxin production in staphylococcal strains.
- To identify specific enterotoxins and their combinations produced by these strains.
- To assess enterotoxin production across different isolation sources.
Main Methods:
- Utilized the immunodiffusion micromethod for enterotoxin detection.
- Analyzed 5974 staphylococcal strains isolated between 1972 and 1978.
- Included strains from food, human milk, and clinical specimens.
Main Results:
- Identified 3001 (approximately 50.2%) enterotoxin-producing staphylococcal strains.
- Detected individual enterotoxins A, B, C, D, and E.
- Observed various enterotoxin combinations, including A+B, A+C, A+D, A+E, B+D, C+E, and A+C+E.
Conclusions:
- A significant proportion of staphylococcal strains isolated during the study period produced enterotoxins.
- The findings highlight the diverse range of enterotoxins and combinations circulating.
- This data provides valuable insights into staphylococcal contamination risks in food and clinical settings.
