Burkholderia pseudomallei is the etiologic agent of the disease melioidosis and is a category B biological threat agent. The genomic sequence of B. pseudomallei K96243 was recently determined, but little is known about the overall genetic diversity of this species. Suppression subtractive hybridization was employed to assess the genetic variability between two distinct clinical isolates of B. p...

Burkholderia mallei is the causative agent of glanders which is a highly contagious and fatal disease of equines. Considering the nature and severity of the disease in equines, and potential of transmission to human beings, glanders is recognised as a 'notifiable' disease in many countries. An increasing number of glanders outbreaks throughout the Asian continents, including India, have been no...

Acyl-homoserine lactones (HSLs) serve as quorum-sensing signals for many Proteobacteria. Members of the LuxI family of signal generators catalyze the production of acyl-HSLs, which bind to a cognate receptor in the LuxR family of transcription factors. The obligate animal pathogen Burkholderia mallei produces several acyl-HSLs, and the B. mallei genome has four luxR and two luxI homologs, each ...

According to the several scientific resources, Iran is considered to be among the melioidosis-endemic regions of the world; this is in stark contrast to the domestic stance in Iran, where the risk of melioidosis is speculated only as an emerging infectious disease in a non-endemic area. Recently, we have had devastating flash floods in the most provinces of Iran; the changing of soil structure ...

Burkholderia is a bacterial genus comprising several pathogenic species, including two species highly pathogenic for humans, B. pseudomallei and B. mallei. B. thailandensis is a weakly pathogenic species closely related to both B. pseudomallei and B. mallei. It is used as a study model. These bacteria are able to exhibit multiple resistance mechanisms towards various families of antibiotics. By...

Burkholderia mallei is an infectious intracellular pathogen whose virulence and resistance to antibiotics makes it a potential bioterrorism agent. Given its genetic origin as a commensal soil organism, it is equipped with an extensive and varied set of adapted mechanisms to cope with and modulate host-cell environments. One essential virulence mechanism constitutes the specialized secretion sys...

ABSTRACT: Glanders is a disease caused by the bacterium Burkholderia mallei that primarily affects horses, mules and donkeys. The can cause lesions in skin, lungs several other organs. However, it often manifests as an asymptomatic disease. In Brazil, serological tests of high sensitivity specificity are used to assist detection antibodies against B. contribute control due mandatory euthanasia ...

Burkholderia mallei is a highly pathogenic bacterium that causes the zoonosis glanders. Previous studies indicated that the genome of the organism contains eight genes specifying autotransporter proteins, which are important virulence factors of Gram-negative bacteria. In the present study, we report the characterization of one of these autotransporters, BpaB. Database searches identified the b...
