Bat coronavirus found for the first time in two Indian species of bats: ICMR study

New Delhi: Earlier, researchers from the Indian Council of Medical Research (ICMR) have found traces of the bat coronavirus (BtCoV) isolated from the novel coronavirus, in two bat species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu.  .

  However, consistent with researchers, there is no evidence to suggest that bat coronaviruses are often transmitted in humans.

  Bats are considered natural reservoirs for many viruses and some of them contain potential human pathogens.  Traces of Nipah virus were earlier found in bats in India.

  A 2017 study also found the presence of Ebola virus-associated antibodies in bats in Nagaland.

  The novel coronavirus or SARS-CoV-2 - which is causing a continuous coronovirus epidemic - is also believed to originate from bats.  About nine bats were found positive for BtCoV

  To assess the presence of coronovirus in bats, researchers identified and characterized bait COV (BTOCV) in Pteropus medius and Rousus species from seven states in India collected during 2018 and 2019.

 A minimum of 29 batsmen from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu were found positive for BtCoV.  Consistent with the study, SARS-CoV-2 is reported to be about 96 percent like BtCoV at the whole genome level.

  Potteropus bat species were found positive for Nipah virus in Kerala within the years 2018 and 2019.  The current study was part of an ongoing effort to find out the spread of Nippa virus in bats.

  The study, however, warns that although coronaviruses (COVs) do not typically cause clinical symptoms in bats, accidental transmission of these viruses to many humans and other animals may end in variable severity in respiratory or neurological diseases.  is.

  The study stated, "It does not make sense that only a few pairs can infect people".

  India has a diverse population of bats: about 117 species of bats are recorded, of which about 100 subspecies are about 100 subspecies belonging to 39 families - Pteropodidae, Rhinolophidae, Hipposideridae, Megadermatidae, Rhinopomatidae, Emballonuridae, Molossidae  And Vperper.

  The National Institute of Virology (ICMR-NIV) in Pune has detected several viruses in bats, including Nipah virus in Pteropus medius, Malsoor virus, Tioman virus and a completely unique adenovirus in Rettettus leschenaultii.

  Nipah viral RNA antibodies are detected in Pteropus bats in many countries and a potential link to transmission from bats to humans may also be established during the Nipah outbreak in Kerala in 2018 and 2019.

  This study underscores the need to increase screening of coronaviruses in bats in India to prevent future outbreaks.
