This study developed a reverse transcriptase-polymerase chain reaction (RT-PCR) detection system for enteric viruses in sample concentrates obtained by conventional filter adsorption-elution methods. One liter beef extract (BE)-glycine (G) eluant seeded with poliovirus 1 and hepatitis A virus (HAV) was used as a model system and the eluant further processed for RT-PCR compatibility. Sample concentration and purification procedures consisted of polyethylene glycol (PEG) precipitation, Pro-Cipitate (Affinity Technology, New Brunswick, NJ) precipitation, a second PEG precipitation, spin-column chromatography, and ultrafiltration. Sample volumes are reduced from 1 L to 20-40 μL and purified sufficiently for viral detection by RT-PCR. As little as 3 PFU of poliovirus 1 in an initial 1 L eluate were detected by RT-PCR.
