BCCI to constitute working group on IPL verdict

New Delhi, Jun 17: Petrol and diesel prices were increased in metros on Wednesday, marking the eleventh straight day of increase since state-owned oil companies returned to the normal practice of daily reviews following a 12-week pause. With effect from 6 am, the price of petrol was increased by 55 paise per litre, and diesel by 69 paise per litre in Delhi, compared to the previous day. While the price of petrol was revised to Rs 77.28 per litre in the national capital from Rs 76.73 per litre the previous day, the diesel rate was increased to Rs 75.79 per litre from Rs 75.19 per litre, according to notifications from state-run Indian Oil Corporation, the country's largest fuel retailer. In the 11-day period, the price of petrol has been increased by a cumulative Rs 6.02 per litre, and diesel by Rs 6.49 per litre.

International crude oil prices retreated on Wednesday, weighed down by an increase in US crude inventories and worries about a potential second wave of the coronavirus pandemic. Brent crude futures - the global benchmark for crude oil - were last seen trading 1.0 per cent lower at $40.56 per barrel.

State-run oil marketing companies revise the prices of petrol and diesel from time to time, besides aviation turbine fuel (ATF) - or jet fuel - and liquefied petroleum gas (LPG). However, since March 16, the oil companies had kept petrol and diesel prices on hold, possibly due to the volatility in global oil markets.

Fuel retailing in the country is dominated by state refiners - Indian Oil Corporation, Bharat Petroleum Corporation and Hindustan Petroleum Corporation. The three own about 90 per cent of the retail fuel outlets in the country.

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.
