U se of the polymerase chain reaction amolificationamplification of targeted nucleotide sequences as a means of identifying microorganisms for diagnostic and epidemiologic purposes 12has initiated a transformation in laboratory based approaches to infectious disease diagnosis and was the subject of an earlier LCDC report 3. The high sensitivity and specificity of properly targeted long chain primer pairs and the great variety of specimens amenable to PCR analysis, including nonculturable specimens such as paraffin embedded tissues, has generated numerous diagnostic applications 4.

Another genetic approach has recently been suggested by two groups 56 in which PCR amplification of DNA polymorphisms was directed by single small primers only eight to 10 nucleotides in length.

Following polyacrylamide gel electrophoresis pagethese demonstrate an array of amplicons that yield a banding fingerprint that is characteristic for each combination of short primer and DNA source. This technique has been designated DNA amplification fingerprinting daf. Particularly important are the specialized silver staining method 8 required for resolution of small, as opposed to large, amplicons, and the primer concentrations required for effective priming.

There appears to be some particular advantages to daf compared to the more traditional PCR approach. The use of long, dual primer PCR requires that there be extensive preexisting knowledge of the target sequences.

There is not such a requirement for daf. The conditions required for effective long chain, dual primer PCR are considerably more stringent with respect to hybridization and enzymatic conditions than for daf. Multiple priming sites on each DNA vingerprinting are amplified efficiently by short primers under relaxed conditions and the number of amplicons reproducibly obtained in daf is largely dependent on the short primer sequence rather than length, provided the number exceeds four 5 — 7.

LCDC has begun the analysis of certain pseudomonads using this technology and we finberprinting shortly be reporting on its efficacy in our hands.

Until then it would seem reasonable to predict that daf technology will provide high versatility while retaining the selectivity and sensitivity of long, dual primer PCR and will shortly be part of the diagnostic trade akplification clinical microbiologists.
