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.

New Delhi, Mar 27: Prime Minister Narendra Modi on Friday described British premier Boris Johnson as a "fighter" and hoped he recovers from coronavirus infection.

"Dear PM @BorisJohnson, you're a fighter and you will overcome this challenge as well," Modi tweeted.

He said he prays for his good health and extends best wishes in ensuring a healthy UK.

Johnson said on Friday that he has tested positive for coronavirus after experiencing mild symptoms and is now self-isolating at 10 Downing Street in line with the medical advice.

"I am now self-isolating, but I will continue to lead the government's response via video-conference as we fight this virus," he said.

New Delhi, Jan 5: A masked mob on Sunday entered the Sabarmati Hostel on the Jawaharlal Nehru University (JNU) campus and assaulted several students and professors with sticks and rods.

"I have been brutally attacked by goons wearing masks. I am bleeding. I was brutally beaten up," JNU Students' Union (JNUSU) president Aishe Ghosh told reporters.

She has been admitted to the AIIMS here for treatment.

Several other students were also injured in the incident.

In a video of the incident, a group of goons with their faces covered can be seen assaulting students with wooden sticks and rods.

A tweet from the official handle of the JNUSU said, "Sabarmati Hostel: right now. They are beating the students who are inside. Knocking on doors with rods. People are jumping from balconies. #SOSJNU #EmergencyinJNU."

"Professors who were trying to protect us have been beaten up. These are unknown ABVP goons, not all are students, they have covered their faces, and they are moving towards the hotels near the West Gate. Stay alert. Make human chains. Protect each other. #SOSJNU #EmergencyinJNU," another tweet added.

Meanwhile, the ABVP's JNU unit claimed in a tweet: "Emergency in JNU. Leftist goons of JNU accompained with their cadre from other universities have crossed every limit. They have proceeded with unimaginable violence on ABVP activists of JNU."
