Antimicrobial resistance isn't just a silent pandemic—India bears one of the heaviest burdens globally.
Even as the country maintains its look for new antibiotics to combat the crisis, researchers are actually turning to naturally occurring viruses within the surroundings as a promising device to assault and kill multi-drug-resistant microorganisms.
Karthik Anantharaman, a touring professor at Wadhwani college of Information Technological Know-How and AI at IIT Madras, is spearheading such a venture within the US by way of reading the character of viruses in their natural habitat to attack and kill bacteria, a manner called phage remedy.
"One method is to create greater antibiotics; however, this merely postpones the problem. New antibiotics also can lead to new styles of resistance, developing a by-no-means-ending cycle. An alternative and promising answer is phage therapy.
Which makes use of viruses called bacteriophages
(or definitely phages) to kill specific microorganisms," Dr. Anantharaman, who's additionally a professor at the university of Wisconsin-Madison, advised indiatoday.in.
Finding VIRUSES THAT KILL bacteria
Anantharaman and his team located that viruses have yearly cycles and might have an effect on other organisms inside the environment.
As part of their look at some viruses, they had found that they held genes they'd taken from the organisms they infected, which helped them perform critical organic capabilities.
The research team also put together over 1.3 million viral genomes—the biggest series of its type thus far.

"In our lab, we're exploring how phages behave through the years. We performed a 20-year observation of a single lake, using dna sequencing and artificial intelligence (AI) to tune how phage populations changed. Via sequencing environmental dna and the use of AI equipment we diagnosed over 1.3 million viral genomes. This allowed us to see how viruses shift month to month, season to season, and 12 months to 12 months, and to anticipate their future behavior," Dr. Anantharaman stated.
While phage therapy would possibly look like an exceptionally new idea to indian populations and even the West, who depend closely on antibiotics, Anantharaman noted that the phenomenon of the use of viruses to kill microorganisms has been used in nations like Russia, Poland, Ukraine, and georgia for decades.
VIRUSES AS ENVIRONMENTAL CLEANERS
"Our purpose is twofold: to enhance human fitness and environmental health. "Simply as phages (viruses) can target harmful microorganisms within the human frame, they can also be used to clean polluted ecosystems," a university of Wisconsin-Madison professor stated.
As an instance, if a lake turns black or emits a scent like rotten eggs, a sign of hydrogen sulfide produced by means of microorganisms, phages can be used to selectively kill those bacteria and restore the lake's health.

Notwithstanding their promise, phage treatment plans are currently used best in compassionate cases, wherein all antibiotics have failed and the affected person's condition is crucial.
HOW DO PHAGES OR VIRUSES PAINTINGS TOWARDS MICROORGANISMS?
One principal reason phages haven't entered mainstream remedy is that researchers still do not fully recognize how they evolve over time.
Therefore, there aren't any authorized phage-primarily based healing products in India, the USA, or Europe.
However, phages preserve tremendous promise, especially when utilized in mixture with antibiotics.
Here's how it works: when microorganisms face antibiotics, they arrive underneath strain. Occasionally, this pressure causes genetic changes that lead them to be resistant.
But in that manner, microorganisms may additionally end up liable to phages. So, using both antibiotics and phages collectively creates an effective, complementary treatment method.
In a few cases, antibiotics work in which phages don't, and vice versa.

"One principal gain of phages is their precision. Unlike antibiotics, which kill each dangerous and useful bacteria, phages target the most effective one specific pressure. If a person is inflamed with Pseudomonas, the phage used will kill the handiest Pseudomonas, sparing the relaxation of the frame's microbiome. "It is a game-changer for keeping standard fitness all through treatment," Anantharaman explained.
Another unexpected fact is that viruses are anywhere—even inside us.
There are 10 to 100 times extra viral debris in and on our bodies than human cells.
These encompass many innocent phages that silently adjust bacterial populations. Phages are determined in lakes, rivers, soil, oceans, and even in our intestines and on our pores and skin.

"In our lab, we use AI—both system learning and deep getting to know—to swiftly pick out phages from environmental samples. This method, which used to take years, now takes just a day. "AI permits us to sift through thousands and thousands of dna sequences and pinpoint the viruses that can infect specific dangerous microorganisms," Anantharaman said.
Limitations PERSIST
But attention stays a first-rate barrier.
The scientific network and industry are still focused on antibiotics. There is confined funding in phage therapy, and the vital research infrastructure hasn't yet been constructed.
For phage remedy to transport ahead, government aid and academic research are crucial.
"Industry isn't presently interested in developing phage-based remedies—it's largely as much as establishments and public investment. But because the danger of antibiotic resistance grows, this is expected to change," Anantharaman opined.
Phage remedy isn't just a scientific curiosity. It could be a prime pillar of destiny medication if we choose to spend money on it.
