| impact of climate on western equine encephalitis in manitoba, minnesota and north dakota, 1980-1983. | information was collected on confirmed outbreaks of western equine encephalitis (wee) in north america east of the rockies for 1981 and 1983 (epidemic years) and 1980 and 1982 (non-epidemic years). the initial pattern of outbreaks in manitoba, minnesota and north dakota was determined for each year. backward (and in some instances forward) wind trajectories were computed for each day 4-15 days (incubation period) before the initial outbreaks of wee in a given area of province or state. during th ... | 1988 | 2905669 |

| prevalence of mycoplasma antibodies in lesser prairie-chicken sera. | serologic testing by the serum plate agglutination (spa) procedure was performed to detect the presence of cross-reacting antibodies to mycoplasma meleagridis, mycoplasma synoviae, and mycoplasma gallisepticum in lesser prairie-chickens (tympanuchus pallidicinctus) trapped over a 2-yr period in finney and kearny counties of southwestern kansas. sera examined from birds (n = 50) obtained in march-april 2000 tested positive for m meleagridis, m. synoviae, and m. gallisepticum at levels of 6%, 10%, ... | 2002 | 12243537 |
| pancreatitis in wild zinc-poisoned waterfowl. | four waterfowl were collected in the tri-state mining district (oklahoma, kansas and missouri, usa), an area known to be contaminated with lead, cadmium and zinc (zn). they were part of a larger group of 20 waterfowl collected to determine the exposure of birds to metal contamination at the site. the four waterfowl (three branta canadensis, one anas platyrhynchos) had mild to severe degenerative abnormalities of the exocrine pancreas, as well as tissue (pancreas, liver) concentrations of zn that ... | 2003 | 14676018 |
| fine-scale distribution modeling of avian malaria vectors in north-central kansas. | infectious diseases increasingly play a role in the decline of wildlife populations. vector-borne diseases, in particular, have been implicated in mass mortality events and localized population declines are threatening some species with extinction. transmission patterns for vector-borne diseases are influenced by the spatial distribution of vectors and are therefore not uniform across the landscape. avian malaria is a globally distributed vector-borne disease that has been shown to affect endemi ... | 2016 | 27232133 |
