Terror threat: J&K govt asks tourists to vacate Valley

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.

Bhopal, Mar 15: Madhya Pradesh Chief Minister Kamal Nath on Saturday sought the intervention of Home Minister Amit Shah for the "release" of 22 Congress MLAs in Karnataka, saying they had been held "captive" and were under "pressure".

In a letter to Shah, Chief Minister Nath said the BJP's demand for floor test had "no meaning" till the MLAs do not reach the state.

He said that the MLAs do not have any means of personal communication and all efforts to reach them have failed.

In the four-page letter, Nath said Governor Lalji Tandon had told him that the responsibility of security of those who will come to meet the Speaker should be with the CRPF but as the Chief Minister, it is his duty to ensure the security of all residents of the state including MLAs.

"I assure you that if these 22 MLAs are released by the Karnataka Police, then I will ensure maximum security by the state government so that they are able to convey their views without fear and take part in the proceedings of the assembly," Nath said.

He urged Shah to use his powers as Home Minister so that 22 MLAs safely reach Madhya Pradesh and discharge their responsibilities "without fear or greed" in the assembly session beginning on March 16."

Chief Minister Nath said that he had been informed that the MLAs had been deprived of all personal communication facilities.

He said that a father was not allowed to meet his son and two ministers who were accompanying the father of the legislator were "arrested" and manhandled by the Karnataka Police.

"My efforts to reach them as also of their relatives have failed which proves my apprehension that they are under captivity."

He said the videos released in the name of MLAs to "mislead" the people of the state were similar. "This proves that all these MLAs are under pressure and they are being forced to act in a particular way," he said.

Nath said that he was drawing Shah's attention to the developments in the state since March 3 which were aimed at destabalising the government.

He said three Congress MLAs, one BSP, and one independent MLA were taken to Gurugram and two ministers of his government were able to "rescue" the BSP legislator.

He said the three Congress MLAs and the independent MLA were later taken to Bengaluru by the BJP. He said a BJP MLA and a party functionary accompanied them.

"Later, 19 Congress MLAs were taken to Bengaluru in chartered planes and the arrangement was done by the BJP," he said, adding that they were accompanied by two former BJP MLAs and a former minister.

Kamal Nath said the number of MLAs in Bengaluru grew to 22 and they are all in the protection of the Karnataka Police.

He said some BJP leaders from Madhya Pradesh can be seen in pictures of the place where the MLAs were staying. "All reported expenses on these MLAs are being borne by the BJP," he said.

He said the BJP leaders had told the media about the resignation of MLAs and they had not presented themselves before the assembly Speaker.

Kamal Nath said he was concerned about the security of the MLAs and had written to the Governor earlier.

"You would agree with me that the demand for floor test has no meaning till the 22 MLAs are in captivity. This is unprecedented that the BJP is demanding floor test and several Congress MLAs have been kept outside the state,' he said.
