Burkholderia - Wikipedia, the free encyclopedia Burkholderia is a genus of proteobacteria probably best-known for its pathogenic members — Burkholderia mallei responsible for glanders, a disease that occurs mostly in horses and related animals, Burkholderia pseudomallei — causative agent of melioidosis and Burkholderia cepacia — an important source of pulmonary infection in people with cystic fibrosis (CF). The use of Burkholderia species for agricultural purposes (such as biodegradation, biocontrol and as plant-growth-promoting rhizobacteria) is subject to discussions because of possible pathogenic effects in immuno-compromised people (especially CF-sufferers), e.g., hospital acquired infections. Due to their antibiotic resistance and the high mortality rate from their associated diseases Burkholderia mallei and Burkholderia pseudomallei are considered to be potential biological warfare agents, targeting livestock and humans. en.wikipedia.org /wiki/Burkholderia   (197 words)

Agricultural Use of Burkholderia (Pseudomonas) cepacia: A Threat to Human Health? Burkholderia (previously known as Pseudomonas) cepacia, a nutritionally versatile, gram-negative organism, was first described in 1949 by Walter Burkholder of Cornell University, as the phytopathogen responsible for a bacterial rot of onions (1) (Figure 1). cepacia isolates are closely related (a panmictic population structure) (18,31,44) and epidemic isolates are scattered throughout (18,31), as demonstrated by rrn-based phylogenic trees, which include large numbers of environmental and clinical isolates.
