| avian cholera in waterfowl: the role of lesser snow and ross's geese as disease carriers in the playa lakes region. | we collected samples from apparently healthy geese in the playa lakes region (usa) during the winters of 2000-01 and 2001-02 to determine whether carriers of pasteurella multocida, the bacterium that causes avian cholera, were present in wild populations. with the use of methods developed in laboratory challenge trials (samuel et al., 2003a) and a serotype-specific polymerase chain reaction method for identification of p. multocida serotype 1, we found that a small proportion of 322 wild birds ( ... | 2005 | 15827210 |
| lead concentrations in liver and kidneys of snow geese during an avian cholera epizootic in california. | during an avian cholera epornitic, between december 1982 and january 1983, 58 dead, 23 sick, and 106 hunter-killed lesser snow geese (chen caerulescens caerulescens) were collected at delevan national wildlife refuge, colusa county, california, usa. fifty-one of the dead and sick geese were infected with pasteurella multocida. lead concentrations in the livers ranged from < 1 to 253 parts per million (ppm) (dry weight). lead concentrations in the kidneys ranged from < 1 ppm to 547 ppm (dry weigh ... | 1993 | 8258858 |
| multi-species patterns of avian cholera mortality in nebraska's rainwater basin. | nebraska's rainwater basin (rwb) is a key spring migration area for millions of waterfowl and other avian species. avian cholera has been endemic in the rwb since the 1970s and in some years tens of thousands of waterfowl have died from the disease. we evaluated patterns of avian cholera mortality in waterfowl species using the rwb during the last quarter of the 20th century. mortality patterns changed between the years before (1976-1988) and coincident with (1989-1999) the dramatic increases in ... | 2006 | 16699151 |
| antibodies against pasteurella multocida in snow geese in the western arctic. | to determine if lesser snow geese (chen caerulescens caerulescens) are a potential reservoir for the pasteurella multocida bacterium that causes avian cholera, serum samples and/or pharyngeal swabs were collected from > 3,400 adult geese breeding on wrangel island (russia) and banks island (canada) during 1993-1996. pharyngeal swab sampling rarely (> 0.1%) detected birds that were exposed to p. multocida in these populations. geese with serum antibody levels indicating recent infection with p. m ... | 1999 | 10479077 |
| pasteurella multocida serotype 1 isolated from a lesser snow goose: evidence of a carrier state. | pharyngeal swabs were collected from 298 lesser snow geese (chen caerulescens caerulescens) at banks island (northwest territories. canada) in the summer of 1994. pasteurella multocida serotype 1 was isolated from an adult male bird and p. multocida serotype 3 was isolated from an adult female goose. pathogenicity of the serotype 1 isolate was confirmed by inoculation in pekin ducks (anas platyrhynchos). the serotype 3 isolate was non-pathogenic in pekin ducks. this is the first documented isola ... | 1997 | 9131570 |
