Pseudomonas antimicrobica Attafuah and Bradbury 1990 is a junior synonym of Burkholderia gladioli (Severini 1913) Yabuuchi et al. 1993

Comparison of the 16S rDNA sequence of Pseudomonas antimicrobica LMG 18920( T) with published 16S rDNA sequences from other pseudomonads indicated that Pseudomonas antimicrobica belongs to the genus Burkholderia, with Burkhold eria gladioli, Burkholderia glumae and Burkholderia plantarii as its closes t neighbours. DNA-DNA hybridizations confirmed that Pseudomonas antimicrobi ca and Burkholderia gladioli represent the same species. Strain LMG 18920T and other Burkholderia gladioli strains were also indistinguishable by SDS- PAGE of whole-cell proteins and had similar biochemical characteristics. Th e whole-cell fatty acid composition, however, was different from that of ot her Burkholderia gladioli strains. It is concluded that Pseudomonas antimic robica is a later synonym of Burkholderia gladioli. As Burkholderia gladiol i is known to cause infections in patients with cystic fibrosis and chronic granulomatous disease, the eventual use of strain LMC 18920(T) as a biolog ical control agent should be approached with caution.
