The infection of Streptococcus pneumoniae, Staphylococcus aureus, and common fungi and antibiotics on teaching tools – micro at campus 2 – Van Lang University

Abstract

A cross - sectional descriptive study to conducted to investigate the infection of Streptococcus pneumoniae, Staphylococcus aureus, and fungi on teaching instruments - microphone at campus 2 Van Lang University. In this research, we carried out 81 samples of microphones in the classrooms, culturing, identifying Streptococcus pneumoniae, Staphylococcus aureus on blood agar, and quantifying fungi on dichloran glycerol agar. The results showed that 64/81 (79.01%) samples contaminated with bacteria; 47/81 (58.02%) samples were infected with fungi. Among the samples contaminated with bacteria, 3/64 (4.70%) samples were infected with Staphylococcus aureus. None of the samples were infected with Streptococcus pneumoniae and pathogenic yeast. Three Staphylococcus aureus isolated were shown to be resistant to Azithromycin, Erythromycin, Penicillin, Tetracycline and one of them was resistant to Clindamycin, Gentamicin, Trimethoprim/ Sulfamethoxazole antibiotics. The data in this study, will provide information for attention when using microphones in teaching, communication, entertainment activities, etc., contributing to limiting the transmission of respiratory infections.
