Ribotyping has previously been used for epidemiological studies of
Burkholderia pseudomallei (previously Pseudomonas pseudomallei). We show
here that random amplified polymorphic DNA (RAPD) analysis allows
subdivision of strains of the same ribotype. With five different primers,
no two epidemiologically unrelated isolates of any single ribotype in this
study of 102 isolates from humans, goats, cats, and soil had identical RAPD
patterns. Conversely, RAPD analysis showed clonality for isolates from each
of two animal outbreaks of melioidosis and from a nontropical focus of
animal and human melioidosis spanning 25 years. Some soil isolates were
identical to epidemiologically related animal and human isolates as
determined by RAPD typing. There was no evidence that the clinical outcome
of melioidosis was related to RAPD patterns.
