Khảo sát sự đề kháng kháng sinh của vi khuẩn gram dương tại Bệnh viện Truyền máu Huyết học

The increase of infections caused by Gram-positive bacteria resistant to antibiotics is not only a challenge in treatment, but also a current issue of the health sector. Objective: To determine the proportion of gram-positive bacteria isolated in Blood Transfusion Haematology Hospital (BTH). To determine the rate of antibiotic resistance of Gram-positive bacteria. Method: The descriptive, cross-sectional study Results: Staphylococci were the highest at 66.9%, Enterococci at 20.9% and Streptococci at 12.2%. Streptococci has a rate of resistance to penicillin antibiotics at a rate of 29%, fully sensitive to vancomycin, linezolid. Enterococci has a very high rate of antibiotic resistance, penicillin resistance 90.6%, vancomycin resistance 43.4%, teicoplanin 24.5%, linezolid 5.7%. Staphylococci is still not resistant to vancomycin, linezolid, sensitivity to teicoplanin 99.4%, penicillin resistance 99.4%, oxacilin 90%. Conclusion: The rate of S.aureus MRSA in BTH is 87.4%, no vancomycin and linezolidresistant strains have been collected. It is necessary to strictly manage the use of antibiotics, especially vancomycin because it is the drug of choice for MRSA.
