                                    Citation: Kapczynski, D.R., Swayne, D.E. 2005. Role of vertical transmission with avian metapneumovirus subtype C following experimental infection of SPF laying turkeys. In: Proceedings of 2005 Turkey Research Review and Avian Pneumovirus Symposium,Oct 5, 2005,Willmar,MN. 2005 CD-ROM.Interpretive Summary: Avian metapneumovirus (aMPV) is responsible for a highly infectious respiratory disease of turkeys.  Although wild birds have been identified as possible vectors for transmission, few reports have examined vertical transmission of aMPV from hen to poult.  In an effort to determine the potential transmission of aMPV by vertical transmission,  laying turkey hens were experimentally infected with U.S. aMPV and eggs examined for the presence of virus during a one-week post-inoculation period.  Results indicate the presence of aMPV, by RT-PCR and virus isolation, on the egg shell and in the embryo.  These are the first results to describe vertical transmission of U.S. aMPV in turkeys.
