Study 2: survival rates of Muscovy ( Cairina moschata ) and Pekin ( Anas platyrhynchos var. domestica ) ducks inoculated by the intranasal (IN), intracloacal (IC), or intraocular (IO) routes with the Egypt/07 or Egypt/08 H5N1 HPAI viruses. Survival rates were not statistically different between the ducks receiving virus by the same route of inoculation as determined by the log rank test (p < 0.05). Survival rates were not different between all Muscovy ducks regardless of the virus, with the exception of ducks inoculated with Egypt/07 via IO and ducks inoculated with Egypt/08 via IC. Survival rates were different between Pekin ducks inoculated with Egypt/07 compared with Egypt/08.
