Duck plague: carrier state and gross pathology in black ducks

Duck plague (UP) is a highly fatal disease of ducks, geese, and swans (family Anatidae), produced by a reticulo-endotheliotrophic virus classified as a member of the Herpesvirus group. The disease was recognized in Europe in 1949. On the American continent, the disease was first diagnosed in the United States in 1967. Very little is known of DP...

New dimensions in diseases affecting waterfowl

We start off with light heart, but as we near the marsh, we stop abruptly in shock and horror. The shoreline, where only last evening we saw thousands of sleek, apparently healthy birds, is now littered with their bodies.

Duck hepatitis virus Interactions with DDT and dieldrin in adult mallards

There has been considerable speculation regarding possible imteractlons within biological systems between synthetic environmental pollutants and infectious disease agents (1-11). This type of interaction has been studied in our laboratory using the mallard, Anas platyrhynchos, as a test species (5,6). Since adult ducks are refractory to the overt...

Interaction between duck hepatitis virus and DDT in ducks

Injections of duck hepatitis virus (DVH) decreased, and exposure to DDT increased, hepatic microsomal mixed-function oxidase activity. Injection of DFV prior to exposure to DDT did not prevent stimulation of hepatic microsomal mixed-function oxidase activity by DDT and may have enhanced it.

Yersinia philomiragia sp. n., a new member of the Pasteurella group of bacteria, naturally pathogenic for the muskrat (Ondatra zibethica)

A bacterium experimentally pathogenic for muskrats (Ondatra zibethica), white mice, mountain voles (Microtus montanus), and deer mice (Peromyscus maniculatus) was isolated from the tissues of a sick muskrat captured on the Bear River Migratory Bird Refuge (Brigham City, Utah) and from four surface water samples collected within 15 miles of that...

The occurrence of Oestrus ovis L. (Diptera: Oestridae) in the bighorn sheep from Wyoming and Montana

Three previous and five new records of the domestic sheep bot, Oestrus ovis, from the bighorn sheep are given. The life history and descriptions of adult and larval forms are presented. The significance of the occurrence of the parasite in the abnormal host is discussed.
