Abstract

Background: Urinary tract infection (UTI) is a common disease. Urinary tract infections can be recurrent if not diagnosed early and treated effectively. Gram-positive bacteria are important pathogens. Subjects and methods: Gram-positive bacteria strains causing urinary tract infections were isolated at Nghe An Friendship Hospital from 1/2021 to 12/2021. Study design: Descriptive cross section. Results: 91 strains of Gram-positive bacteria causing UTIs were isolated, in which, Enterococcus faecium accounted for the highest proportion (40.7%), Enterococcus faecalis ranked second at 33.0%. Staphylococcus aureus, Streptococcus agalactiae fight a low percentage of isolated pathogens. Enterococcus faecium is 100% resistant to many antibiotics Ampicillin, Penicillin, Ciprofloxacin, Levofloxacin, 13.9% vancomycin resistance, no Linezolid resistance has been recorded. Enterococcus faecalis is resistant to Quinolones group 63.3%, to Linezolid 3.6%, vancomycin resistance has not been recorded. Conclusion: Enterococcus faecalis, Enterococcus faecium are the most common Gram-positive pathogens. The isolated bacteria were resistant to many commonly used antibiotics to varying degrees. There were linezolid-resistant Enterococcus faecalis (3.6%), vancomycin-resistant Enterococcus faecium (13.9%).
