An epizootic of common loons in coastal waters of North Carolina: Concentrations of elemental contaminants and results of necropsies An epizootic of common loons in coastal waters of North Carolina: Concentrations of elemental contaminants and results of necropsies

A 1993 die-off of common loons (Gavia immer) in the coastal waters of North Carolina was investigated with emphasis on comparing mercury, selenium, arsenic, and lead between birds from the epizootic and reference specimens. Die-off specimens were emaciated but contained no ingested foreign bodies and no lesions suggestive of infectious disease. Results of bacteriology, virology...

Helminth parasites of the bald eagle, Haliaeetus leucocephalus, in Florida Helminth parasites of the bald eagle, Haliaeetus leucocephalus, in Florida

Twenty species of helminths (9 trematodes, 9 nematodes, and 2 acanthocephalans), including 9 new host records, were collected from 40 bald eagles (Haliaeetus leucocephalus) from Florida. Intensities of infection were low and no lesions were attributed to the parasites. No species were considered specialists in bald eagles; 5 species were considered raptor generalists and the remainder...

Three closely related herpesviruses are associated with fibropapillomatosis in marine turtles Three closely related herpesviruses are associated with fibropapillomatosis in marine turtles

Green turtle fibropapillomatosis is a neoplastic disease of increasingly significant threat to the survivability of this species. Degenerate PCR primers that target highly conserved regions of genes encoding herpesvirus DNA polymerases were used to amplify a DNA sequence from fibropapillomas and fibromas from Hawaiian and Florida green turtles. All of the tumors tested (n= 23) were found...

Amphibian malformations Amphibian malformations

Frog malformations have been reported from 42 states. The broad geographic distribution of these malformations warrants national attention. Scientists at the USGS National Wildlife Health Center in Madison, Wisconsin are studying this problem in an effort to document its scope and to determine the causes of the observed malformations.

Blood lead concentrations of spectacled eiders near the Kashunuk River, Yukon Delta National Wildlife Refuge, Alaska Blood lead concentrations of spectacled eiders near the Kashunuk River, Yukon Delta National Wildlife Refuge, Alaska

We collected, 342 blood samples from spectacled eiders (Somateria fischeri) on their breeding grounds in western Alaska from late May through to early August 1993–1995. Lead concentrations of ≥0.50 p.p.m. wet weight were found in the blood of 20% of the adult female eiders, 2% of the adult males and 6% of the ducklings. Lead was detected (≥0.02 p.p.m.) more frequently in the blood of...

A cryopreservation method for Pasteurella multocida from wetland samples A cryopreservation method for Pasteurella multocida from wetland samples

A cryopreservation method and improved isolation techniques for detection of Pasteurella multocida from wetland samples were developed. Wetland water samples were collected in the field, diluted in dimethyl sulfoxide (DMSO, final concentration 10%), and frozen at -180 C in a liquid nitrogen vapor shipper. Frozen samples were transported to the laboratory where they were subsequently...
