comparison of the association of age with the infection of salmonella and salmonella enterica serovar typhimurium in pekin ducks and roman geese.nontyphoid salmonella have a broad host range in poultry and mammals, and serovar typhimurium is a threat to public health. in this study, normal and sick ducks and geese were collected from 12 farms in taiwan to investigate the age-associated infection of salmonella and salmonella typhimurium in roman geese (anser anser domesticus) and pekin ducks (anas platyrhynchos domesticus). in normal birds, the prevalence of salmonella differed between species, and with age [e.g., 1-wk group, 37.5% (30/80 ...200818648047
isolation, identification, and complete genome sequence of an avian reticuloendotheliosis virus isolated from geese.naturally occurring lymphoreticular tumors in geese have been found from time to time in taiwan, but their etiology has not been determined except through morphological descriptions. this study observed a reticuloendotheliosis virus (rev) infection occurring in a white roman goose (anser anser) farm in yunlin, taiwan in 2006. these geese showed growth-retarded and nodular lymphoma-like tumors in the liver, lung, kidney, and pancreas. thirty blood samples were taken for rev detection and 21 (70%) ...200919131189
