Test code: B0087 - Qualitative ultrasensitive detection of
by real time PCR.
Delftia acidovorans was formerly called
Comamonas acidovorans or Pseudomonas acidovorans.
Prior to 1987, a number of now-independent genera, including
Delftia, Burkholderia, Stenotrophomonas, Ralstonia, Comamonas,
Acidovorax and others, were all grouped within the broad
genus Pseudomonas. In general, these bacteria are
aerobic, oxidase-positive, Gram-negative bacilli that grow on
MacConkey's agar. When this broad genus was rearranged based on
rRNA sequencing data, D. acidovorans was grouped into
the family Comamonadaceae based on 16S rRNA gene sequence
analysis. However, Comamonas acidovorans was later
found to be phylogenetically quite distant from the other
species of Comamonas (Wen et al., 1999), and was
therefore renamed Delftia acidovorans.
Morphologically, D. acidovorans
appears as straight to slightly curved Gram-negative bacilli,
occurring singly or in pairs. Strains are motile by means of
polar or bipolar tufts of one to six flagella. The organism is
strictly aerobic and is a common water and soil saprophyte.
D. acidovorans is normally of limited virulence and is
usually considered an opportunistic pathogen. Due to its
widespread occurrence, it is often implicated in the
contamination of medical devices such as intravascular catheters
Culture differentiation of D.
acidovorans can be difficult because it shares many
biochemical and growth characteristics with other bacteria in
the Pseudomonas genus. Molecular detection by PCR is
highly specific and sensitive and can often be used instead of
culture to detect and identify D. acidovorans
