THE CLINICAL FEATURES AND THE ANTIBIOTIC RESISTANCE OF BACTERIA CAUSING IMPETIGO AT CAN THO HOSPITAL CITY OF DERMATO-VENEREOLOGY
Main Article Content
Abstract
Background: Impetigo is a highly contagious skin infection that is most common in children. Previously, topical antibiotics used as major treatment, and oral antibiotics were indicated only for serious cases. However, according to recent researches, topical antibiotic resistance of S. aureus and S. pyogenes has been increasing. Objectives: To demonstrate clinical features and antibiotic resistance of bacteria causing impetigo in patients at Can Tho city Hospital of DermatoVenereology from June 2020 to December 2020. Materials and methods: A descriptive crosssectional study of 55 patients, clinical characteristics of patients with impetigo were recorded. Bacteria from impetigo pus were isolated. Antibiogram examination with multiple antibiotics performed. Results: 35 (63.6%) patients with impetigo had positive bacteriological cultures. Regarding clinical features, non-bullous impetigo was 61.8%, bullous impetigo was 25.5% and ecthyma was 12.7%. On the examination of biology features, S. aureus was 93.8% of cases. Penicillin-resistant S. aureus and Erythromycin-resistant S. aureus was 100%; Amoxicillin/acid clavulanic-resistant S. aureus was 93.5%; bacteria were sensitive to Cefuroxime, Oxacillin, Tetracyclin, Ciprofloxacin, Levofloxacin, Linezolid and Vancomycin; the 3 case Vancomycinresistant was ecthyma. Methicillin-Resistant Staphylococcus aureus (MRSA) was 87.1%. And 2 S. pyogenes cases (8.6%) remained susceptible to Penicillin. Conclusion: Non-bullous impetigo was the most common clinical feature. The main bacterium is S. aureus, which was completely resistant to Penicillin and Erythromycin. On the other hand, it was still highly sensitive to Oxacillin, Cefuroxime, Vancomycin and Linezolid.
