The feasibility of using Flinders Technology Associates (FTA) cards for the molecular detection of avian metapneumovirus (aMPV) by reverse transcriptase-polymerase chain reaction (RT-PCR) was investigated. Findings showed that no virus isolation was possible from aMPV-inoculated FTA cards, confirming viral inactivation upon contact with the cards. The detection limits of aMPV from the FTA card and tracheal organ culture medium were 101.5 median ciliostatic doses/ml and 100.75 median ciliostatic doses/ml respectively. It was possible to perform molecular characterization of both subtypes A and B aMPV using inoculated FTA cards stored for up to 60 days at 4 to 6°C. Tissues of the turbinate, trachea and lung of aMPV-infected chicks sampled either by direct impression smears or by inoculation of the tissue homogenate supernatants onto the FTA cards were positive by RT-PCR. However, the latter yielded more detections. FTA cards are suitable for collecting and transporting aMPV-positive samples, providing a reliable and hazard-free source of RNA for molecular characterization.
