The use of repetitive extragenic palindromic (REP)-PCR to characterise non-capsulate Haemophilus influenzae (NCHI) for epidemiological studies was validated by application to four outbreak-associated and three epidemiologically unrelated NCHI strains of the same phenotype which had been well characterised by other methods. The REP-PCR patterns were reproducible and showed the unrelated isolates to be distinguishable from each other, whereas the outbreak-associated isolates were indistinguishable. The results were concordant with those from outer-membrane protein enriched profiles, ribotyping and randomly amplified polymorphic DNA analysis. When applied to six further isolates from two different suspected outbreaks, rapid results were obtained from boiled supernates prepared from one colony and indicated that the isolates in question were not related. REP-PCR provides a rapid method of strain characterisation suitable for NCHI, which is ideal for use in conjunction with other methods.

D015203	Reproducibility of Results	The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
