Growth conditions
Biochemical characters
Phylum Proteobacteria, Class  Betaproteobacteria, Order Burkholderiales, Family Burkholderiaceae, Genus Burkholderia,
Burkholderia gladioli
, Yabuuchi et al. 1993. Pseudomonas antimicrobica Attafuah and Bradbury 1990 it's a junior synonym.

Old synonyms:
Pseudomonas gladioli Severini 1913;  Pseudomonas marginata
McCulloch 1921;
- 4 pathovars: gladioli, alliicola, agaricicola, cocovenenans.
Gram-negative rods. Motile at room temperature, nonmotile at 37 ºC.
Poli-beta-hydroxybutyrate inclusions are present.
Strictly aerobic, growth temperature 30 ºC. Can Grow at 41 ºC. Fluorescent diffusible
pigments are not produced. Grows on media: Trypticase Soy Agar ± 5% sheep blood,
Mac Conkey agar. Usually non-haemolytic.
Isolated from plants, soil, human clinical samples (respiratory).
Mainly a plant pathogen – onion bulb  rot (pv. alliicola),  grain rot & leaf-sheath browning in rice plants, leaves pathogen for some
orchidaceous plants (cymbidium, dendrobium, and oncidium leaves) & gladiolus (pv. gladioli).  On gladiolus corms produce water-
soaked brown spots, outlined in yellow which can become hollow and surrounded by scabs, leaving behind cavities or lesions when
removed. Causes soft rot of cultivate mushrooms (pv. agaricicola).
Antagonistic to plant pathogenic fungi.
Pathovar coccovenenans is a human pathogen, involved in food poisoing (2 toxin produced: toxoflavin & bongkrekic acid).
Nosocomial infections; isolated from respiratory samples of patients with cistic fibrosis & from otitis media infection.  2 cases of
isolation from chronic granulomatous disease reported. Keratitis, absceses.
