BACKGROUND In this study, a Burkholderia mallei tonB mutant (TMM001) deficient in iron acquisition was constructed, characterized, and evaluated for its protective properties in acute inhalational infection models of murine glanders and melioidosis. METHODOLOGY/PRINCIPAL FINDINGS Compared to the wild-type, TMM001 exhibits slower growth kinetics, siderophore hyper-secretion and the inability t...

From the many existing documents on the history of glanders, it is possible to detail the practical measures adopted for disease surveillance and control from antiquity until the 19th century, principally in European countries. Surveillance is based on clinical diagnosis, post-mortem examination, animal inoculation and knowledge of the conditions under which infection occurred: aetiology, patho...

Burkholderia mallei is a highly infectious gram-negative pathogen and is the causative agent of human and animal glanders. By generating polar mutations (disruption of bsaQ and bsaZ) in the B. mallei ATCC 23344 animal pathogen-like type III secretion system (TTS), we demonstrate that this bacterial protein delivery system is required for intracellular growth of B. mallei in J774.2 cells, format...

Sixteen strains designated Mycobacterium farcinogenes, fifteen Mycobacterium senegalense, and ten Nocardia farcinica were, together with strains of Mycobacterium and Nocardia, subjected to numerical phenetic analyses using 96 unit characters. The data were examined using the simple matching (SSM), Jaccard (SJ) and pattern (DP) coefficients and clustering achieved using the unweighted average li...
