In news

The Nipah virus has been found in two species of bats in Maharashtra for the first time by scientists from the Pune-based National Institute of Virology (NIV).

Key updates

  • The new study ‘Detection of possible Nipah virus infection in Rousettus leschenaultii and Pipistrellus bats in Maharashtra, India’, published in the Journal of Infection and Public Health has found the virus and antibodies in different species. 
  • The NIV article states that India has witnessed four Nipah outbreaks so far.

  • The NIV team looked at Pteropus medius, Rousettus leschenaultii and Pipistrellus pipistrellus bats that are common in India. 
  • It trapped 65 leschenaultii and 15 pipistrellus bats and collected blood, throat and rectal swabs in the Mahabaleshwar cave from the anaesthetised bats.
  • One bat each from R leschenaultii and P pipistrellus species tested positive for both NiV RNA and anti NiV IgG antibodies
  • This is the first report of possible NiV infection in R leschenaultii bats in India, which was demonstrated by the presence of both NiV RNA and anti-NiV IgG antibodies in bats.
  • Leschenaultii bats were found to harbour Nipah for the first time in India.
  • Pteropus medius bats, which are large fruit-eating bats, are the incriminated reservoir for NiV in India as both NiV RNA and antibodies were detected in the samples of these bats collected during previous NiV outbreaks.

About Nipah Virus

  • The virus, usually found in bats, features in the top 10 priority list of pathogens identified by the World Health Organisation, and its transmission to humans has resulted in deadly outbreaks across the world.
  • Nipah is considered dangerous as there is no medicine or vaccine, and the death rate is high.
  • It has a death rate of 65% to 100%.
  • The Nipah virus is a type of RNA virus in the genus Henipavirus.
  • The infection is generally believed to be emerging from fruit bats from the Pteropodidae family.
  • Nipah’s symptoms are similar to influenza, including fever, muscle pain and breathing problems.

Rousettus leschenaultii 

  • Leschenault’s rousette is a species of fruit bat. 
  • The scientific name of the species was first published by Desmarest in 1820.
  • Leschenault’s rousette is brown to grey-brown in colour with lighter underparts.
  • This bat species is found in a variety of habitats ranging from tropical forests to urban environments. 
  • It roosts in caves, old abandoned buildings and tunnels, and other such structures.  

Pipistrellus bats

  • The common pipistrelle is a small pipistrelle microbat whose very large range extends across most of Europe, North Africa, South Asia, and may extend into Korea. 
  • The common pipistrelle is a very small species of bat. 
  • It has a short muzzle.
  • The common pipistrelle is an edge specialist, preferring to forage along woodland edges and along isolated tree lines.
  • It is insectivorous, preying on flies, caddisflies, lacewings, and mayflies.
  • Mosquitoes, midges, and gnats are particularly favored prey items.
