[Characteristics of th staphylococci isolated from slaughtered sheep]
Veterinarno-Meditsinski Nauki
|January 1, 1980
Summary
This study analyzed 449 staphylococcal strains from small ruminant carcasses, finding Staph. Saprophyticus most common. Biochemical tests like mannite fermentation and phosphatase activity aid in differentiating these meat-contaminating bacteria.
Area of Science:
- Microbiology
- Food Safety
- Bacteriology
Context:
- Investigated staphylococcal strains from slaughtered sheep and lambs in meat-producing facilities.
- Analyzed 449 isolates for type composition and biochemical properties.
Purpose:
- To determine the prevalence of different staphylococcal species in small ruminant meat production.
- To evaluate the utility of biochemical tests for differentiating staphylococcal species.
Summary:
- Identified Staph. Saprophyticus (55.01%) as the predominant species, followed by Staph. Epidermidis (33.85%) and Staph. Aureus (11.14%).
- Mannite fermentation under anaerobic conditions is characteristic of coagulase-positive staphylococci from this source.
- Phosphatase activity is common in Staph. Aureus and Staph. Epidermidis, limiting its use in differentiating Staph. Aureus.
- Staph. Aureus strains were typed using bacteriophages, with common phagotypes including 116, 118, and 53/77.
Impact:
- Provides crucial data on staphylococcal contamination in the meat industry.
- Highlights the limitations of certain biochemical tests in bacterial identification.
- Contributes to understanding the epidemiology and phage typing of Staph. Aureus in livestock.
