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.

Bengaluru, Jul 20: Karnataka on Monday reported 3,648 COVID-19 cases taking the tally to 67,420, informed the state health department.

According to a bulletin issued by the department, the state recorded 72 more deaths due to COVID-19 with the toll at 1,403 while six patients who tested positive for the infection have died due to non-COVID causes, as of Monday.

There are 42,216 active cases in the state.
As many as 730 patients were discharged today, taking the total discharged patients to 23,795.
Bengaluru recorded the highest number of cases and deaths today at 1,452 and 31, respectively, informed the state health department.

India's COVID-19 case tally crossed the 11-lakh mark with the highest single-day spike of 40,425 new cases and 681 deaths reported in the last 24 hours, said the Union Health and Family Welfare Ministry on Monday.

The total cases in the country now stand at 1,118,043 while the death toll is 27,497.

The ministry said the total number of cases include 390,459 active cases and 700,087 cured/discharged/migrated.

Udupi, Jan 30: Fishermen in Udupi’s Malpe have netted ‘spanner crab’, a rare variety of deep sea crab, mostly found in Australia and Hawaiian coast.

Hundreds of onlookers were surprised to the see the catch when it was brought to Malpe harbour by the fisherman Prashanth Kunder and others on Tuesday evening.

Dr Shivakumar Haragi, Assistant Professor at Karnatak University, PG Centre Department of Marine Biology, Karwar identified this crab variety as ‘spanner crab’ and the scientific name of this crab is Ranina Ranina.

Ranina Ranina is mainly nocturnal as it remains active during night and is found buried in sand during the day .It is easily distinguished from other crab species in its habitat due to its red carapace and elongated midsection.

Resembling a frog in its shape, this crab species is found mainly in Africa, Hawaiian coast and also in the Great Barrier Reef, located in the Coral Sea, off the coast of Queensland, Australia. Its lifetime is seven to nine years and each crab weighs around 400-900 grams.

Prashanth Kunder and his associates have also netted a rare fish variety called yellow-edged lyretail. Another unique variety fish netted by Prashanth is epinephelus flavocaeruleus.
