Pigeon with microchip found in Gujarat, anti-terror squad begins probe

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.

Kolkata, Jan 12: Prime Minister Narendra Modi on Sunday said a section of the youth is being misguided about the Citizenship Amendment Act and asserted that it will not take away anybody's citizenship.

Modi also said whoever has faith in India and believes in its Constitution can become an Indian citizen.

“There are a lot of questions among the youth about the new citizenship law, and some are being misled by rumours around it... it is our duty to clear their doubts,” the PM said during an address at Belur Math in Howrah district.

“I want to make this clear again that the CAA is not about taking away anybody's citizenship, but about granting citizenship,” he added.

Modi said that some people with political interests are deliberately spreading rumours about the new citizenship law.

Lauding the youth for speaking against religious persecution of minorities, the prime minister said the energy of the country's young will form the basis of change in the 21st century. The PM is on a two-day visit to the city.

New Delhi, May 7: Food ordering and delivery platform Swiggy on Thursday said its co-founder and CTO Rahul Jaimini will move away from active role in the company during the month to pursue another entrepreneurial venture.

Jaimini will be joining Pesto Tech, a career accelerator start-up, as their co-founder, Swiggy said in a statement.

He will continue to be a shareholder and board member of Swiggy, it added.

Functions currently led by Rahul, including platform engineering, analytics, IT and labs, will be realigned to Dale Vaz, Head of Engineering and Data Science, who has been with the company for close to two years, the statement said.

"Technology was crucial to what we set out to build when we started Swiggy. Nandan (Reddy) and I could not have asked for a better partner to handle this aspect of the company," Swiggy co-founder and CEO Sriharsha Majety said.

It was Rahul's immense passion to 'build for the billions' that drove technological innovations that set Swiggy apart as we grew phenomenally over the years, he added.

"Working with technology that has large scale impact is what excites me, and I am grateful to have had the opportunity to do just this at Swiggy and grow tremendously over the years," Jaimini said.
