Burkholderia mallei and Burkholderia pseudomallei, the etiologic agents responsible for glanders and melioidosis, respectively, are genetically and phenotypically similar and are category B biothreat agents. We used an in silico approach to compare the B. mallei ATCC 23344 and B. pseudomallei K96243 genomes to identify nucleotide sequences unique to B. mallei. Five distinct B. mallei DNA sequen...
Background Burkholderia pseudomallei is a Gram-negative saprophytic soil bacterium that causes melioidosis, a potentially fatal disease endemic in wet tropical areas. The currently available biochemical identification systems can misidentify some strains of B. pseudomallei. The aim of the present study was to identify the biochemical features of B. pseudomallei, which can affect its correct ide...
Melioidosis, the infection caused by the saprophytic bacterium Burkholderia pseudomallei, is endemic in south-east Asia and northern Australia [1]. Sporadic cases have been reported from the Indian subcontinent and it is an emerging infection in India [2]. A low prevalence of antibodies against melioidosis among hospitalassociated groups in Colombo had been reported in 1976 [3], as well as a re...
The bacterium Burkholderia ubonensis is commonly co-isolated from environmental specimens harbouring the melioidosis pathogen, Burkholderia pseudomallei. B. ubonensis has been reported in northern Australia and Thailand but not North America, suggesting similar geographic distribution to B. pseudomallei. Unlike most other Burkholderia cepacia complex (Bcc) species, B. ubonensis is considered no...
Cytokine mRNA levels were assessed in Burkholderia pseudomallei-susceptible BALB/c mice and B. pseudomallei-resistant C57BL/6 mice following administration of a sublethal dose of less virulent (LV) B. pseudomallei, a candidate immunogen tested for protection against a highly virulent (HV) challenge. Compared on the basis of the bacterial loads, the cytokine patterns induced by HV and LV B. pseu...
A study was made on the growth and survival of Pseudomonas pseudomallei in culture environments differing in nutrients, initial pH, and aeration, in comparison with Pseudomonas cepacia and Pseudomonas aeruginosa. The observations led us to a view that P. pseudomallei has the highest adaptability to acidic environments among the three species. Unlike the other species, it grew in heart infusion ...
BACKGROUND Burkholderia pseudomallei is the causative agent of melioidosis, a disease of significant morbidity and mortality in both human and animals in endemic areas. Much remains to be known about the contributions of genotypic variations within the bacteria and the host, and environmental factors that lead to the manifestation of the clinical symptoms of melioidosis. METHODOLOGY/PRINCIPAL...
Melioidosis is an emerging infectious disease caused by the soil bacterium Burkholderia pseudomallei. In diagnostic and forensic settings, molecular detection assays need not only high sensitivity with low limits of detection but also high specificity. In a direct comparison of published and newly developed TaqMan PCR assays, we found the TTS1-orf2 assay to be superior in detecting B. pseudomal...
Clinical definitions of melioidosis and inhalation-acquired melioidosis (Burkholderia pseudomallei infection) are described together with the evidence used to develop these definitions. Such definitions support accurate public health reporting, preparedness planning for deliberate B. pseudomallei release, design of experimental models, and categorization of naturally acquired melioidosis.
Burkholderia pseudomallei is rarely isolated from cystic fibrosis patients outside known areas of endemicity. We report the recovery of B. pseudomallei from the sputum of a cystic fibrosis patient who lives in Brazil. We highlight the importance of careful attention to unusual nonfermentative gram-negative rods in cystic fibrosis patients.
