Burkholderia pseudomallei and Burkholderia mallei: Melioidosis and Glanders
The genus Burkholderia is currently composed of many species, but only three are notable pathogens for humans or animals: the former cepacia complex (described in Chapter 220) pseudomallei (the agent of melioidosis), and mallei (the agent of equine glanders). All three are aerobic, nonsporulating, straight or slightly curved gram-negative bacilli that were formerly placed in the genus Pseudomonas.
متن کاملDevelopment of Burkholderia mallei and pseudomallei vaccines
Burkholderia mallei and Burkholderia pseudomallei are Gram-negative bacteria that cause glanders and melioidosis, respectively. Inhalational infection with either organism can result in severe and rapidly fatal pneumonia. Inoculation by the oral and cutaneous routes can also produce infection. Chronic infection may develop after recovery from acute infection with both agents, and control of inf...
متن کاملMolecular and physical characterization of Burkholderia mallei O antigens.
Burkholderia mallei lipopolysaccharide (LPS) has been previously shown to cross-react with polyclonal antibodies raised against B. pseudomallei LPS; however, we observed that B. mallei LPS does not react with a monoclonal antibody (Pp-PS-W) specific for B. pseudomallei O polysaccharide (O-PS). In this study, we identified the O-PS biosynthetic gene cluster from B. mallei ATCC 23344 and subseque...
متن کاملThe Genetic and Molecular Basis of O-Antigenic Diversity in Burkholderia pseudomallei Lipopolysaccharide
Lipopolysaccharide (LPS) is one of the most important virulence and antigenic components of Burkholderia pseudomallei, the causative agent of melioidosis. LPS diversity in B. pseudomallei has been described as typical, atypical or rough, based upon banding patterns on SDS-PAGE. Here, we studied the genetic and molecular basis of these phenotypic differences. Bioinformatics was used to determine...
متن کاملColony morphology variation of Burkholderia pseudomallei is associated with antigenic variation and O-polysaccharide modification.
Burkholderia pseudomallei is a CDC tier 1 select agent that causes melioidosis, a severe disease in humans and animals. Persistent infections are common, and there is currently no vaccine available. Lipopolysaccharide (LPS) is a potential vaccine candidate. B. pseudomallei expresses three serologically distinct LPS types. The predominant O-polysaccharide (OPS) is an unbranched heteropolymer wit...
