Abstract:
Over the period 1983-1985, investigators from the Institute of Hygiene and Epidemiology, Prague, and the Central Research Institute of Epidemiology, USSR Ministry of Public Health, Moscow, carried out a joint study of drug resistance in S. aureus strains in relation to their enterotoxigenic properties and phage group specificity. Altogether 277 strains were explored which had been isolated at random from the clinical material from infant and adult inpatients. Most of the isolated strains featured multiple resistance to antibiotics: PNC (77.9%), CMP (52.7%), TET (21.6%), ERY (17.6%) and LIN (11.9%). The strains isolated from infants were most frequently resistant to TET and ERY. No correlation was found between the incidence of antimicrobial drugs resistance and toxigenic properties of the isolated strains.
Insights
This study examined antibiotic resistance in Staphylococcus aureus strains from clinical settings. Most strains showed multiple drug resistance, but no link was found between resistance and toxin production.
Area of Science:
- Microbiology
- Infectious Diseases
- Epidemiology
Background:
- Staphylococcus aureus is a significant pathogen in both hospital and community settings.
- Understanding antimicrobial resistance patterns is crucial for effective treatment strategies.
- Previous research has explored S. aureus resistance, but specific correlations with enterotoxigenicity require further investigation.
Purpose of the Study:
- To investigate the prevalence of antibiotic resistance in clinical S. aureus isolates.
- To determine the relationship between antimicrobial drug resistance and enterotoxigenic properties.
- To analyze phage group specificity in relation to drug resistance.
Main Methods:
- A joint study was conducted between the Institute of Hygiene and Epidemiology, Prague, and the Central Research Institute of Epidemiology, Moscow.
- A total of 277 S. aureus strains were randomly isolated from infant and adult inpatients between 1983-1985.
- Antimicrobial resistance profiles, enterotoxigenic properties, and phage group specificity were assessed.
Main Results:
- The majority of S. aureus strains exhibited multiple drug resistance.
- High rates of resistance were observed for Penicillin (PNC, 77.9%), Chloramphenicol (CMP, 52.7%), Tetracycline (TET, 21.6%), Erythromycin (ERY, 17.6%), and Lincomycin (LIN, 11.9%).
- Strains isolated from infants showed a higher frequency of resistance to Tetracycline and Erythromycin. No correlation was found between antimicrobial resistance and the toxigenic properties of the strains.
Conclusions:
- Multiple antibiotic resistance is prevalent in clinical S. aureus isolates.
- Infant isolates demonstrated a notable resistance pattern to Tetracycline and Erythromycin.
- Antimicrobial resistance in S. aureus strains was not associated with their enterotoxigenic potential in this study.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
