Abstract

Aims: Evaluation on the bacterial identification for specimens and antibiotic response of bacteria in year 2022 at Tam Tri Sai Gon General Private Hospital. Methods: Retrospective study on 400 specimens for bacterial identification and on 99 positive bacteria with antibiotic sensitivity test results in year 2022. Results: The overall positive bacterial identification rate is 24.75% (99/400). The highest rate recorded in exudate fluid/pus (79.8%), the lowest one in stool specimen (7.69%). The Klebsiella spp. bacteria (52.7%) was commonly in sputum, Staphylococcus aures (46.15%) in exudate/pus, E. coli (40%) in urine, Staphylococcus aures (42.86%) in blood culture. Rank order of the incidence from highest to lowest was Klebsiella spp. (1^st, n=23), S. aureus (2^nd, n=16), M. tuberculosis (3^rd, n=15),  E. coli (4^th, n=14), Beta-hemolytic Streptococci not group A (4^th, n=14), and Staphylococcus  spp. coagulase (-) (5^th, n=7). Klebsiella spp. (ESBL+) had 3 antibiotics, sensitivity rate >87.5%, as colistin, fosfomycin and polymycin B, and Amikacin (62.5%). E.coli (ESBL+) had 3 antibiotics, sensitivity rate 75%, as Amikacin, Colistin and Netilmicin. S. aureus and Staphylococcus coagulase (-) were only sensitive with Netilmicin, Ticarcillin/Clavulanic acid and Vancomycin. For Pseudomonas aeruginosae had only 2 sensitive antibiotics, as Colistin and Polymycin B. Beta-hemolytic Streptococci not group A was sensitive with  many antibiotics including Amox/Clavulanic acid (100%). The experimental antibiotics were proposed as: Amikacin for Gram(-), Vancomycin for S. aureus, and Amox/Clavulanic for Hemolytic Strep. Not group A. Conclusion: It is necessary to perform the bacterial identification and antibiotic sensitivity test per annual to follow-up the change in bacterial variation and the bacterial sensitivity against antibiotics in each particular hospital with function of treatment of bacterial infections.
