http://burkholderia.com/index.jsp 伯克霍尔德氏菌属拉丁学名(Burkholderia Yabunchi et al.，1993) 1993年，薮内根据16S rRNA序列分析，DNA／DNA同源性、细胞类脂及脂肪酸组成等特征的研究结果，提出将假单胞菌属的Palleroni rRNA同源群Ⅱ组改名为伯克霍尔德氏菌属 (Burkholderia)。属内的种包括洋葱伯克霍尔德氏菌(B． cepacia)、椰毒伯克霍尔德氏菌(B．cocovenenans)、鼻疽伯克霍尔德氏菌(B．mallei)、类鼻疽伯克霍尔德氏菌 (B．pseudomallei)、石竹伯克霍尔德氏菌(B． caruophylli)、唐菖蒲伯克霍尔德氏菌(B．gladioli)、皮氏伯克霍尔德氏菌(B．picketti)及茄伯克霍尔德氏菌 (B．solanacearum)，近年来又增加了4个种，植物伯克霍尔德氏菌(B．plantarii)、荚壳伯克霍尔德氏菌(B． glumae)、范氏伯克霍尔德氏菌(B．vandii)和越南伯克霍尔德氏菌(B．vietnamiensis)。 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 Burkholderia (previously part of Pseudomonas) genus name refers to a group of virtually ubiquitous gram-negative, motile, obligately aerobic rod-shaped bacteria including both animal/human (see above) and plant pathogens as well as some environmentally-important species. In particular, B. xenovorans (previously named Pseudomonas cepacia then B. cepacia and B. fungorum) is renowned for their ability to degrade chlororganic pesticides and polychlorinated biphenyls (PCBs). 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.
