Abstract

Menangle virus, a recent addition to the family Paramyxoviridae, subfamily Paramyxovirinae, was isolated in 1997 from stillborn piglets at a large commercial piggery in New South Wales, Australia, during the investigation of an outbreak of severe reproductive disease, which persisted from April to September of that year.1 The index piggery, which housed 2600 sows in four separate breeding units, was located approximately 60 km southwest of Sydney on a property that was adjacent to the Nepean River. 2,3 The disease was characterized by a reduction in both the farrowing rate and the number of live piglet births per litter, occasional abortions, and an increase in the proportion of mummified and stillborn piglets, some of which had deformi-ties. 1,2,4 Although Menangle virus was only ever isolated from affected stillborn piglets, subsequent seroepidemiological investigations led to the implementation of a successful eradication program,3 the identification of a likely natural host (fruit bats, also known as flying foxes, in the genus Pteropus),1 and the unexpected realization that the virus had infected two piggery workers, causing severe influenza-like illness and a rash.5
