Мененгл вирусі: шошқалар, адамдар және жануарлар арасындағы жұқпалы ауру

Species of virus

Menangle pararubulavirus, also called Menangle virus, is a virus that infects pigs, humans and bats.

Menangle virus was first identified in 1997 after a piggery in Menangle near Sydney, NSW, Australia experienced a high number of stillbirths and deformities during farrowing. Two workers at the piggery came down with an unexplained serious flu like illness, but subsequently recovered. They later tested positive for Menangle virus antibodies. This outbreak was quickly controlled through disinfection and temporary depopulation of individual units in the pig farm.

The source of the outbreak may have been a nearby population of fruit bats or flying foxes. Bats appear to be an asymptomatic host. Infection is thought to occur through serious contact with bodily fluids from infected animals (i. e. blood and possibly foetal matter). Menangle is related to the recently discovered Tioman virus which is also bat borne. Menangle is one of three recently discovered zoonotic viruses in Australia that are carried by bats. The others are Hendra virus and Australian bat lyssavirus (ABLV or bat rabies).

Like all paramyxoviruses, Menangle virus has an envelope, negative sense ssRNA, and pleomorphic (both spherical and elongated forms) proteins (HN and fusion) which protrude from the surface as spikes that help the virus get into cells. As an RNA virus, it must enter the cell to replicate.
