Enterotoxin production by atypical Staphylococcus aureus from poultry.
The Journal of Applied Bacteriology
|April 1, 1983
Summary
Atypical Staphylococcus aureus strains were found in sick and healthy poultry, with some producing enterotoxins. These findings are crucial for understanding poultry diseases and food safety.
Area of Science:
- Veterinary Microbiology
- Poultry Pathology
- Food Safety
Background:
- Femoral head necrosis is a significant poultry disease.
- Staphylococcus aureus is a common pathogen in poultry.
Purpose of the Study:
- To investigate the characteristics of Staphylococcus aureus strains isolated from poultry with femoral head necrosis.
- To determine if atypical strains possess enterotoxigenic potential.
Main Methods:
- Isolation and characterization of Staphylococcus aureus from necrotic bone and liver samples.
- Identification of atypical strains based on key diagnostic tests (coagulase, mannitol fermentation, DNase).
- Enterotoxin production assays for isolated strains.
Main Results:
- Phenotypically typical Staphylococcus aureus was frequently isolated from affected poultry.
- Atypical Staphylococcus aureus strains, differing in major diagnostic tests, were also isolated.
- These atypical strains were found in both diseased birds and healthy birds' nasal swabs.
- Enterotoxin production was confirmed in some atypical strains from both sources.
Conclusions:
- Atypical Staphylococcus aureus strains are present in poultry populations, including healthy individuals.
- The enterotoxigenic capability of these atypical strains poses a potential risk.
- Further research is needed to understand the role of these strains in poultry health and food safety.
