Abstract:

Objective: To understand the common pathogens of acne and their biological characteristics in college students.Methods: The facial swabs of acne college students were isolated and cultured, and the drug sensitivity was measured by K-B method.Results: Of 196 samples, 60 strains of Staphylococcus aureus were isolated（infection rate 30.6%）, and there were 49 strains（25%）of Staphylococcus epidermidis, 26 strains（13.3%）of Streptococcus, 41 strains（20.9%）of G+ diplococcus, 8 strains（4.1%）of yeast and 21 strains（10.7%）of other species. There were 125 samples（63.8%）in which two or more species were isolated. Additionally, the resistant rates of Staphylococcus aureus against penicillin G, cefoperazone, amikacin, azithromycin, roxithromycin and levofloxacin were
76.7%, 1.7%, 8.3%, 50.0%, 60.0% and 8.3%, respectively. Conclusion: The main pathogen of acne in this population is G+ coccus, most of which are mixed infections, and there is intrinsic resistance in some specimens.

Key words: facial acne, pathogens, college students
