Nasal carriage of Staphylococcus aureus: Frequency and antibiotic resistance in healthy adults
Bibliographic record
Abstract
BACKGROUND: This study aimed to determine the frequency of nasal carriage and antibiotic susceptibility profile of Staphylo- coccus aureus (S. aureus) among healthy young adults who referred to premarital screening clinics. METHODS: A cross-sectional study including 158 adults (79 men and 79 women) was conducted at health care centers, Isfahan, Iran, during February-August 2008. Nasal swabs from anterior nares of healthy adults were cultured and tested for S. aureus. Antibiotic susceptibility testing was performed on Muller-Hinton Agar using disc diffusion method according to Clinical Laboratory Standards Institute (CLSI). RESULTS: The prevalence of S. aureus nasal carriage was 26.6%. Resistance to penicillin had the highest rate. The isolates demon- strated higher sensitivity to vancomycin, clindamycin, and rifampicin. In addition, twenty-two S. aureus isolates had intermediate re- sistance to antibiotics. CONCLUSIONS: The importance of implementing strategies to eliminate nasal carriage of S. aureus to pre- vent the spread of infection is highlighted. Effective strategies in this field are thus strongly recommended.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
