Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

New Delhi, Jul 7: Diesel price in the national capital on Tuesday touched an all-time high following a rate hike after a week-long hiatus.

Diesel price on Tuesday was increased by 25 paise per litre, according to a price notification of state-owned oil marketing companies.

This took the retail selling price of diesel to Rs 80.78 per litre in the national capital - the highest ever.

There was no change in petrol price for the 8th straight day, and it continues to be priced at Rs 80.43 per litre.

Rates vary from state to state depending on the incidence of local sales tax or VAT.

Petrol and diesel price were last revised on June 29.

In the last one month, diesel price has been increased on 23 occasions while petrol rates have risen 21 times.

The cumulative increase since the oil companies started the cycle on June 7, totals to Rs 9.17 for petrol and Rs 11.39 in diesel.

In Mumbai, petrol is priced at Rs 87.19 - unchanged since June 29, while diesel was hiked to Rs 79.05 a litre from Rs 78.83.

Bhopal, Mar 10: The number of MLAs who have resigned from the Congress in Madhya Pradesh climbed to 20 on Tuesday afternoon with another legislator quitting the ruling party, sources said.

While 19 MLAs, most of them believed to be loyal to expelled party leader Jyotiraditya Scindia, have sent their resignation letters via e-mail to Raj Bhavan, Bisahulal Singh submitted his resignation letter as an MLA to the Assembly speaker.

"We have received resignations of 19 MLAs through e-mails with attachments," a Raj Bhawan official told PTI.

Sources in Congress produced a copy of Bisahulal Singh's resignation letter which he submitted to the speaker.

Former chief minister and senior BJP leader later announced that Singh (65) has joined the BJP.
