Ectoparasites of Ring-necked Pheasants in Nebraska

Ectoparasites of ring-necked pheasants in Nebraska.

In 1971, 1983 and 1984, ectoparasites were identified on 61 ring-necked pheasants (Phasianus colchicus) from Nebraska. Birds were collected throughout the state from 11 of 93 counties. Four species of chewing lice (Mallophaga) were collected: Lipeurus maculosus, Goniodes colchici, Lagopoecus colchicus and Amyrsidea megalosoma. One species of analgid mite, Megninia sp. was collected. Apparently,...

Seasonal Changes in Thymus in Ring-necked Pheasants

The thymus, a paired lymphoid gland located in the neck region or upper abdominal cavity in birds and mammals, has been the subject of considerable attention in recent years. This gland plays a major role in the immunological system, being indispensable for the development of lymphoid cells in the lymph nodes, spleen, and other lymphoid organs; the thymus, itself, does not form antibodies (Haur...

Comparison of the replication of influenza A viruses in Chinese ring-necked pheasants and chukar partridges.

We investigated the replication and transmission of avian influenza A viruses in two species thought to be intermediate hosts in the spread of influenza A viruses in live poultry markets: Chinese ring-necked pheasants and chukar partridges. All 15 hemagglutinin subtypes replicated in pheasants, and most subtypes transmitted to naïve contact pheasants, primarily via the fecal-oral route. Many vi...

Microscopic fungi in eggs of ring-necked pheasants kept in aviaries.

Pheasant eggs of different colors differ with regard to physical properties. This study was conducted to ascertain the intensity of infestation by microscopic fungi based on egg color. Settling intensity by microscopic fungi of pheasant egg shells and the content of eggs of different color during a 7-d storage period was investigated. The content of ergosterol (ERG) was used as a quantitative i...
