Burkholderia is a genus of Pseudomonadota whose pathogenic members include the Burkholderia cepacia complex, which attacks humans and 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 pathogen of pulmonary infections in people with cystic fibrosis (CF). Burkholderia species is also found in marine environments. S.I. Paul et al. (2021) isolated and characterized Burkholderia cepacia from marine sponges of the Saint Martin's Island of the Bay of Bengal, Bangladesh.
Burkholderia cepacia complex (BCC), or simply Burkholderia cepacia, is a group of catalase-producing, lactose-nonfermenting, Gram-negative bacteria composed of at least 20 different species, including B. cepacia, B. multivorans, B. cenocepacia, B. vietnamiensis, B. stabilis, B. ambifaria, B. dolosa, B. anthina, B. pyrrocinia and B. ubonensis. B. cepacia is an opportunistic human pathogen that most often causes pneumonia in immunocompromised individuals with underlying lung disease. Patients with sickle-cell haemoglobinopathies are also at risk. The species complex also attacks young onion and tobacco plants, and displays a remarkable ability to digest oil. Burkholderia cepacia is also found in marine environments and some strains of Burkholderia cepacia can tolerate high salinity. S.I. Paul et al. (2021) isolated and biochemically characterized salt tolerant strains of Burkholderia cepacia from marine sponges of Saint Martin's Island of the Bay of Bengal, Bangladesh.
Burkholderia cenocepacia is a Gram-negative, rod-shaped bacterium that is commonly found in soil and water environments and may also be associated with plants and animals, particularly as a human pathogen. It is one of over 20 species in the Burkholderia cepacia complex (Bcc) and is notable due to its virulence factors and inherent antibiotic resistance that render it a prominent opportunistic pathogen responsible for life-threatening, nosocomial infections in immunocompromised patients, such as those with cystic fibrosis or chronic granulomatous disease. The quorum sensing systems CepIR and CciIR regulate the formation of biofilms and the expression of virulence factors such as siderophores and proteases. Burkholderia cenocepacia may also cause disease in plants, such as in onions and bananas. Additionally, some strains serve as plant growth-promoting rhizobacteria.
Burkholderia pyrrocinia is a Gram-negative bacterium which has been found in soil as well as in the sputum of patients with cystic fibrosis.
Burkholderia anthina is a species of bacteria of the family Burkholderiaceae.
Burkholderia stabilis is a species of bacteria.
Walter Hagemeyer Burkholder was an American plant pathologist who helped establish the role of bacteria as plant pathogens. He was awarded a Ph.D. by Cornell University in 1917 and subsequently appointed as professor of plant pathology.
Paraburkholderia bryophila is a Gram-negative, catalase- and oxidase-positive, non-spore-forming, and nonmotile bacterium of the genus Paraburkholderia and the family Burkholderiaceae. Research has shown that P. bryophila demonstrates anti-fungal activity against phytopathogens and the growth of plant-associated properties.
Paraburkholderia nodosa is a gram-negative, catalase and oxidase-positive, non-spore-forming, bacterium from the genus Paraburkholderia and the family Burkholderiaceae which was isolated from nitrogen-fixing nodules from roots of Mimosa bimucronata and Mimosa scabrella.
