| plasmodium forresteri n. sp., from raptors in florida and southern georgia: its distinction from plasmodium elongatum morphologically within and among host species and by vector susceptibility. | plasmodium forresteri n. sp. naturally infects eastern screech-owls (otus asio), great horned owls (bubo virginianus), barred owls (strix varia), bald eagles (haliaeetus leucocephalus), red-shouldered hawks (buteo lineatus), broad-winged hawks (buteo platypterus), and red-tailed hawks (buteo jamaicensis) in florida and southern georgia. schizonts occur in mature or nearly mature erythrocytes, produce 2-6 merozoites arranged most commonly in fan or cruciform configuration, with mean dimensions am ... | 1997 | 9379302 |
| patterns, trends, and toxicological significance of chlorinated hydrocarbon and mercury contaminants in bald eagle eggs from the pacific coast of canada, 1990-1994. | bald eagle (haliaeetus leucocephalus) eggs were collected during incubation, 1990-1992, from 16 nests near three bleached-kraft pulp mills, from six nests in the fraser river estuary and from seven nests at a reference site on the pacific coast of canada. polychlorinated dibenzo-p-dioxins (pcdds) and polychlorinated dibenzofurans (pcdfs) were present in all eggs in a qualitatively similar pattern among sites. mean concentrations of 2,3,7, 8-tetrachlorodibenzo-p-dioxin (tcdd) were significantly h ... | 1996 | 8854829 |
| avian vacuolar myelinopathy outbreaks at a southeastern reservoir. | avian vacuolar myelinopathy (avm) is a neurologic disease of unknown etiology that affects bald eagles (haliaeetus leucocephalus), american coots (fulica americana), and several species of waterfowl. an unidentified neurotoxin is suspected as the cause of avm, which has been documented at several reservoirs in the southeastern united states. we conducted diagnostic and epidemiologic studies annually during october-march from 1998-2004 at clarks hill/strom thurmond lake on the georgia/south carol ... | 2006 | 17092880 |
