| Summary |
In order to evaluate the role of pigeons and quails in the H5N2(LPAI) outbreak from December 2003 to April 2004 in Taiwan, pigeons and quails were inoculated intranasally with the avian influenza virus (031209, A/chicken/Taiwan/1209/03(H5N2)) which was firstly isolated from chickens. In the 21 days experimental period, no clinical sign was observed in pigeons and quails. In quails, virus can be isolated from swabs at 2 and 3 DPI, but no virus from any organs except trachea. Pigeons were resistant to this strain; even there was no seroconversion after virus challenge. Seroconvertion was firstly detected at 6 DPI in quails indicating that quails are susceptibility to A/chicken/Taiwan/1209/03(H5N2) as a result of immune response to this strain.
