Abstrakt: | Background: Burkholderia pseudomallei is a causative agent of melioidosis. Ceftazidime is the preferred drug of choice for treatment. However, the motility rate is high in endemic areas. Objective: This study aimed to determine the susceptibility tofour different antimicrobial agents and to detect the β-lactamase genes in B. pseudomallei isolates from patients admitted to Sappasitthiprasong Hospital. Material and Method: 85 B. pseudomallei isolates from patients admitted to Sappasitthiprasong Hospital between November 2010 and May 2011 were determined for antimicrobial susceptibility by standard disk diffusion and minimum inhibitory concentration (MIC). Real-time polymerase chain reaction (PCR) was used for the detection of bla(penA) and bla(OXA) in β-lactamase genes. Results: Almost all of the clinical isolates ofB. pseudomallei were susceptible to ceftazidime and imipenem. Cefatzidime MIC was ≤ 1-16 μg/ml and imipenem MIC was ≤ 1-4 μg/ml. The real-time PCR revealed that more than 90% of B. pseudomallei isolates carried bla(PenA) and bla(OXA). Conclusion: Although the clinical isolates of B. pseudomallei were susceptible to ceftazidime and imipenem, this study showed B. pseudomallei had a gene that produced beta-lactamase enzyme and may be poorly effective in the use of beta-lactam drugs. |
