Abstract
Burkholderia pseudomallei, the highly infectious and causative organism of melioidosis, was first identified in Myanmar in 1911. B. pseudomallei was identified in Myanmar because of its genetic relatedness to Burkholderia species. In this study, we identified two isolates of Burkholderia cenocepacia, two Acinetobacter baumannii complexes, and 18 clinical isolates of B. pseudomallei using Vitek 2. These isolates were first screened using a latex agglutination test, which showed positive results in 20 of the 22 isolates. All isolates were cultured on Ashdown՚s agar and further tested using molecular methods. Specific PCR for type III secretion system (TTSs) gene clusters indicated 19 B. pseudomallei isolates out of 22 isolates. Furthermore, 16S rRNA and recA gene sequencing were used as the gold standard methods and yielded the same results. RapID NF Plus detected 16 B. pseudomallei out of 22 isolates. Vitek 2 and RapID NF Plus should be considered key tools in the diagnosis of melioidosis and surveillance of B. pseudomallei in Myanmar; however, accurate identification must be confirmed by TTS1 PCR. This study evaluated the presumptive workflow for the investigation of B. pseudomallei infections using different methods and options, in line with the available equipment.
