Abstract:

A reverse transcriptase-polymerase chain reaction (RT-PCR) assay was employed to amplify a G gene transcript of the avian pneumovirus (APV) in two European turkey isolates and two Brazilian chicken isolates. The PCR products were digested using restriction endonucleases and the restriction patterns were compared with earlier reported isolate patterns. The same PCR products were cloned into pUC18 and sequenced. Restriction patterns and sequence analyses of the approximately 600 bp products from both Brazilian isolates revealed 99% identity with earlier reported subgroup A APV sequence, suggesting that these isolates belong to this subgroup.
