Indonesia, April 21, 2017: Komodo dragons, fearsome giant lizards found in Indonesia, may be a source of a potent antibiotic. If so, researchers say the agent could be an answer to the growing, global health problem of antibiotic resistance.

Huge, toothy and aggressive, Komodo dragons are surrounded by filth in their daily lives. As a result, Barney Bishop, a biochemist at George Mason University near Washington, said Komodo dragons have developed what he called a “robust” immune system.

Bishop studies molecules produced by the immune system as a front-line defense against infection. That, he said, is the reason for the interest in Komodos.

“They are known to eat carrion; they live in an unsanitary environment; they have been recorded to have up to 57 bacterial strains in their mouths,” some of which can cause disease, he said. “Yet the reptiles themselves are not harmed by these bacteria, whether it’s in their mouths or wounds inflicted by other lizards.”

Bishop and his colleagues, working with blood from Komodos, isolated peptides, or small proteins, produced by the reptiles’ immune systems. The peptides, Bishop said, seem to have remarkable anti-bacterial properties.

Artificial version tested

Researchers made artificial versions of these peptides and tested the most promising one — DRGN-1, or DRAGON-1 — in wounded mice and human skin cell cultures. They found the protein molecules exhibited three outstanding properties: They destroyed the outer layer of bacteria, dissolved biofilms — a sticky colony that microbes form to shield against antibiotics — and speeded up healing.

The work with Komodo dragon peptides was published in the journal Biofilms and Microbiomes.

Bishop said, “Their peptides may offer some promise and some new insights or provide new templates for development of new therapeutics to treat infection.”

Bishop said the three-pronged action of DRGN-1, if made into an antibiotic, would make it unlikely that disease-causing bacteria could become drug-resistant.

The Defense Threat Reduction Agency, an agency of the U.S. Defense Department, paid for the research. The military is interested in the work because it may relate to bioweapons.

Samples of blood for the study were taken from a 45.3-kilogram (100-pound) male Komodo dragon named Tujah who lives at the St. Augustine Alligator Farm and Zoological Park in Florida.

Bishop said only a one-time sample of blood was needed because the peptides were artificially reproduced, so no animal was harmed for the study. (VOA)

June 17, 2018:

Restaurateurs Prodyut and Sumana Mukherjee have not only brought Indian cuisine to the ongoing FIFA World Cup 2018 here but also plan to dish out free dinner to countrymen if Argentina wins the trophy on July 15.

Based in Moscow for the last 27 years, Prodyut and Sumana run two Indian eateries, “Talk Of The Town” and “Fusion Plaza”.

Both restaurants serve popular Indian dishes like butter chicken, kebabs and a varied vegetarian spread.

During the ongoing FIFA World Cup 2018, there will be 25 per cent discount for those who will possess a Fan ID (required to watch World Cup games).

There will also be gifts and contests on offers during matches in both the restaurants to celebrate the event.

The Mukherjees, hailing from Kolkata, are die-hard fans of Argentina. Despite Albiceleste drawing 1-1 with Iceland in their group opener with Lionel Messi failing to sparkle, they believe Jorge Sampaoli’s team can go the distance.

“I am an Argentina fan. I have booked tickets for a quarterfinal match, a semifinal and of course the final. If Argentina goes on to lift

“We have been waiting for this World Cup. Indians come in large numbers during the World Cup and we wanted these eateries to be a melting point,” he added.

According to Cutting Edge Events, FIFA’s official sales agency in India for the 2018 World Cup, India is amongst the top 10 countries in terms of number of match tickets bought.

Prodyut came to Moscow to study engineering and later started working for a pharmaceutical company here before trying his hand in business. Besides running the two restaurants with the help of his wife, he was into the distribution of pharmaceutical products.

“After Russia won the first match of the World Cup, the footfall has gone up considerably. The Indians are also flooding in after the 6-9 p.m. game. That is the time both my restaurants remain full,” Prodyut said.

There are also plans to rope in registered fan clubs of Latin American countries, who will throng the restaurants during matches and then follow it up with after-game parties till the wee hours.

“I did get in touch with some of the fan clubs I had prior idea about. They agreed to come over and celebrate the games at our joints. Those will be gala nights when both eateries will remain open all night for them to enjoy,” Prodyut said.

Watching the World Cup is a dream come true for the couple, Sumana said.

“We want to make the Indians who have come here to witness the spectacle and feel at home too. We always extend a helping hand and since we are from West Bengal, we make special dishes for those who come from Bengal,” she added. (IANS)
