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, Mar 4: BJP leader Devendra Fadnavis on Tuesday said Maharashtra Chief Minister Uddhav Thackeray should not give "vague" replies on the 5 per cent Muslim quota issue and declare "with courage" that his government will not bring law granting reservation to the minority community.

Mr Fadnavis made the remark after Mr Thackeray, during a press conference earlier in the day, said he has not yet received the proposal regarding giving quota to Muslims and that the Shiv Sena-led government is yet to take any decision on it.

Mr Thackeray made the comments after Maharashtra Minority Affairs Minister Nawab Malik recently said in the legislative council that thestate government will provide 5 per cent quota to Muslims in education.

Mr Malik, an NCP leader, had also said the state government will ensure that a legislation to this effect is passed soon.

The NCP and the Congress, both proponents of Muslim quota, are constituents of the Sena-led Maha Vikas Aghadi government.

Asked about Mr Thackeray's remarks on the issue, Mr Fadnavis said instead of making comments at the press conference, the chief minister should make a statement in the legislature which is currently having its budget session.

The Leader of the Opposition in the assembly said that Mr Malik's opinion is the official position of the government as the minister had talked about giving quota in the council.

"So, instead of making vague comments in the press conference, the chief minister should say in the council that it is not his view (the one expressed by chief minister).

"The chief minister gave vague answers during the press conference, saying the proposal has not come to him. Your minister (Malik) only has said it," Mr Fadnavis told reporters outside the legislature building complex.

The BJP leader maintained there is no provision in the Constitution for religion-based reservation in government jobs or education.

"Say with courage that you will not give the quota, that the Constitution doesn't accept quota based on religion. Hence, we (the government) will not bring law granting quota," the former Chief Minister said.

Mr Fadnavis claimed that if given within the 50 per cent ceiling set by the Supreme Court, the Muslim quota will affect the existing reservation granted to OBCs.

"And if given outside it, it will affect Maratha quota," he added.

New Delhi, Feb 11: Delhi BJP chief Manoj Tiwari on Tuesday said the party will review why it failed to meet its own expectations in the Assembly polls and saw a moral victory in the fact that the party's vote share has increased since 2015.

"Delhi must have given mandate after careful thinking. Our vote percentage has increased from 32 per cent to around 38 per cent. Delhi did not reject us and the increase (in vote share) is a good sign for us," he told reporters.

He said the BJP hopes that there would be less blame game and more work in the national capital and congratulated Arvind Kejriwal on his party's victory in the polls.

After winning the Patparganj seat, AAP senior leader Manish Sisodia accused the BJP of indulging in the politics of hate.

"We indulge in politics of development not politics of hate. We're against the roadblock in Shaheen Bagh as we were earlier," he said.
