Nasal carriers of Staphylococcus aureus among healthy individuals
Abstract:
Staphylococcus aureus and Staphylococcus spp. were isolated from healthy students and their drug resistance was investigated. S. aureus was isolated from 17 of 70 persons (24.3%). Fourteen strains of 22 isolates of S. aureus were ampicillin-resistant. Two strains each were cefmetazole-resistant and gentamicin-resistant. None of the strains was found to be methicillin-resistant. Compared with the strains isolated from the hospital ward environment, S. aureus in healthy individuals was relatively sensitive to antibiotics.
Insights
Staphylococcus aureus was found in 24.3% of healthy students, with most resistant to ampicillin. However, these strains showed greater antibiotic sensitivity compared to those from hospital environments.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Staphylococcus aureus is a common bacterium that can cause infections.
- Understanding antibiotic resistance in healthy populations is crucial for public health.
- The prevalence and resistance patterns of S. aureus in community settings require investigation.
Purpose of the Study:
- To investigate the prevalence of Staphylococcus aureus and Staphylococcus spp. in healthy students.
- To determine the drug resistance patterns of S. aureus isolates from this population.
Main Methods:
- Bacterial isolation and identification from healthy student samples.
- Antimicrobial susceptibility testing of isolated S. aureus strains.
Main Results:
- Staphylococcus aureus was isolated from 17 out of 70 healthy students (24.3%).
- Ampicillin resistance was observed in 14 out of 22 S. aureus isolates.
- Two strains each showed resistance to cefmetazole and gentamicin; no methicillin resistance was detected.
Conclusions:
- A significant proportion of healthy students carry Staphylococcus aureus.
- While ampicillin resistance is notable, S. aureus from healthy individuals exhibit relative sensitivity to antibiotics compared to hospital strains.
