Inclusion body disease of cranes: A serological follow-up to the 1978 die-off

A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality diagnosed as being caused by inclusion body disease of cranes (IBDC). Overcrowding and environmental conditions in 1978 may have contributed to the deaths of certain species of cranes in one area and not in another. Mortality ratios and serological data suggest that crane species vary in their response to IBDC virus.

Aspergillosis in a red-crowned crane

An unusual form of pulmonary aspergillosis in a red-crowned crane ( Grus japonensis ) is described in this report. The major lesion is unique because it closely resembles a lesion referred to as an aspergilloma. An aspergilloma is a single large granulomatous lesion that resembles a tumor and is caused by fungi of the genus Aspergillus.

The isolation of a herpes virus from captive cranes with an inclusion body disease

A viral agent, identified as a herpesvirus and tentatively called 'inclusion body disease of cranes' (IBDC), was isolated from captive cranes involved in a die-off at the International Crane Foundation near Baraboo, Wisconsin. Preliminary animal susceptibility tests, based on experimental infections, suggested that White Pekin ducklings up to 17 days old and adult coots were susceptible to the IBDC virus whereas 16-day-old White Leghorn chicks and 64-day-old Muscovy ducks were not. No serum antibody to IBDC virus was detected in 95 wild sandhill cranes collected in Wisconsin or Indiana in 1976 and 1977. However, 9 of 11 captive cranes in the affected area at the ICF had antibody to this agent.
