Coronaviruses found in two Kerala bat species: ICMR study

New Delhi, Apr 15: As the world grapples with coronavirus, researchers have found the presence of a different kind of coronavirus -- bat coronavirus (BtCoV) --in two bat species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu, according to a study by the Indian Council of Medical Research (ICMR).

There is no evidence or research to claim that these bat coronaviruses can cause disease in humans, said Dr Pragya D Yadav, Scientist at the National Institute of Virology (NIV), Pune and also the first author of study.

The study has been published in the Indian Journal of Medical Research,

Twenty-five bats of Rousettus and Pteropus species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu were found positive for BtCoV in Kerala, Himachal Pradesh, Puducherry and Tamil Nadu.

"These bat coronaviruses have no relation with SARS-CoV2 responsible for the COVID-19 pandemic," Yadav said, adding that Pteropus bat species were earlier found positive for Nipah virus in 2018 and 2019 in Kerala.

"Bats are considered to be the natural reservoir for many viruses, of which some are potential human pathogens. In India, an association of Pteropus medius bats with the Nipah virus was reported in the past. It is suspected that the recently emerged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also has its association with bats," the objective of the study titled 'Detection of coronaviruses in Pteropus and Rousettus species of bats from different states of India' stated.

"In the present scenario of changing demography and ecological manipulations, it is challenging to have checks on the encounters of bats with other animals and humans," the study stated, highlighting that the need for active and continuous surveillance remains crucial for outbreak alerts for bat-associated viral agents with epidemic potential, which would be helpful in timely interventions.

"Although CoVs in the subfamily coronavirinae do not usually produce clinical symptoms in their natural hosts (bats), accidental transmission of these viruses to humans and other animals may result in respiratory, enteric, hepatic or neurologic diseases of variable severity. It is still not understood as to why only certain CoVs can infect people," the study said.

The scientists stressed on the need of proactive surveillance of zoonotic infections in bats.

The detection and identification of such viruses from bats also recommends cross-sectional antibody surveys (human and domestic animals) in localities where the viruses have been detected.

Similarly, if the epidemiological situation demands, evidence-based surveillance should also be conducted, the study said while emphasing on the need of developing strong mechanisms for working jointly with various stakeholders such as wildlife, poultry, animal husbandry and human health departments.

"In conclusion, our study showed detection of bat CoVs in two species of Indian bats. Continuous active surveillance is required to identify the emerging novel viruses with epidemic potential," Dr Yadav said.

Elaborating on the study, Dr Yadav said throat and rectal swab samples of two bat species -- Rousettus and Pteropus -- from seven states were screened for the bat coronvirus during which the representative samples collected from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu tested positive while those from Karnataka, Chandigarh, Punjab, Telengana, Gujarat and Odisha came out negative.

The reverse-transcription polymerase chain reaction (RT-PCR) tests and sequencing were used for the confirmation of the findings.

"This is an ongoing study to understand the prevalence of the Nipah virus in bats," she said.

Mumbai, Jul 24: Reliance India Limited (RIL) on Friday overtook ExxonMobil to become the world's second most valuable energy company and 46th among the world's largest companies by market capitalisation.

RIL's market capitalisation stood at Rs 14.16 lakh crore (USD 189.3 billion) at market close on Friday. ExxonMobil's current market value is USD 184.77 billion.

"Reliance Industries, with a market capitalisation of USD 189.3 billion now is the second-most valuable energy company in the world. Reliance Industries now stands at 46th among the world's largest companies by market capitalisation ahead of well-known names like ExxonMobil, Abbott Laboratories, Oracle Corp, Chevron and Unilever Plc, and just below PepsiCo," RIL said in an official release.

RIL continued its rally on Friday, notwithstanding overall weak market conditions.

RIL shares made a new all-time high of Rs 2,163 and were last traded at Rs 2,148.8 on NSE with a gain of 4.4 per cent. The market capitalisation of fully paid-up shares stands at Rs 13.62 lakh crore (USD 182.06 billion), the release said.

Reliance partly paid-up shares gained 9.33 per cent on NSE today to last trade at Rs 1289.95. The partly paid-up shares now have a market capitalisation of Rs 0.55 lakh crore (USD 7.29 billion).

"Reliance's share price had touched a bottom of Rs 867 on March 23, 2020, when the total market value of the company stood at Rs 5.5 lakh crore or $73.5 billion. Thus, RIL has added $115.9 billion to shareholder wealth within just four months - one of the highest value creation feats in the world in such a short time," the release said.

Reliance had earlier raised Rs 212,809 crore through Rights Issue, combined investments in Jio Platforms and investment by bp.

Lucknow, Jan 6: Undeterred by the large scale protests that claimed as many as 20 lives in the state, Uttar Pradesh government has started the process of implementing the controversial Citizenship (Amendment) Act.

According to sources in the government, the district magistrates have been directed to identify the migrants from Pakistan, Bangladesh and Afghanistan, who have been living in their districts.

Sources said that the state home department has given oral instructions to the district magistrates. ''No written orders have been issued,'' said a senior official here preferring anonymity.

The official said that the district magistrates would be preparing a list containing names of those minorities, who had migrated from these countries following their persecution and had been living without obtaining the citizenship of India.

According to sources, the government expected that the migrants, who could be eligible for the Indian citizenship in accordance with the CAA, could be more in number in the districts, including Rampur, Ghaziabad, Shahjahanpur, Lucknow and some others.

''The list will be sent to the union home ministry,'' the official added.

Sources said that the state government will also inform the centre about the ''illegal Muslim migrants'' for their ultimate deportation to their countries of origin.

Different parts of UP had witnessed large scale violence last month during the protests against the CAA. At least 20 people, mostly youngsters, were killed allegedly in police firing and many others were injured. The state government had denied the charge. 

Alleged police excesses during and after the protests triggered a nationwide outrage with several rights organisations and activists slamming the BJP government and demanding a high-level probe into the allegations.
