The Occurrence of Newcastle Disease Antihemagglutinin in Human Sera and Its Relationship to Mumps Virus

[摘要] 1. 1. A serological and epidemiological survey of poultry workers exposed to Newcastle disease virus (NDV) thru infections in their chickens failed to reveal evidence that this agent had been responsible for human illness in this group.2. 2. An inhibitor of hemagglutination by NDV was found in sera from such exposed individuals and just as frequently in sera from individuals not similarly exposed. The occurrence of this inhibitor was found to be closely related to the occurrence of mumps antibodies. Cross absorption studies of such sera with NDV and mumps virus suggested that the NDV inhibitor represented an immunological overlap to infection by mumps virus. Similar interrelationships were not demonstrable in such sera by cross absorption experiments with influenza virus, nor in absorption experiments with specific antisera to NDV or mumps virus.3. 3. NDV may share antigenic components similar to or identical with antigenic components present in other infectious agents.
