The ‘good viruses’ fight bacteria
GS Paper - 3 (Health and Diseases)
Scientists now talk of a virome — all the different types of viruses we host in our bodies which contribute to health, much like the bacterial microbiome. This virome is huge. You have 380 trillion virus particles living (or existing) in or on your body right now — 10 times more than the number of bacteria. These viruses lurk in our lungs and blood, live on our skin and linger inside the microbes in our guts. They’re not all bad, however: There are viruses that kill cancer cells and help break down tumors, others that train our immune system and help them fight pathogens, and even some that control gene expression in pregnancy.
Bacteriophages: Anti-bacterial guard dogs
The vast majority of viruses inside us are bacteriophages — viruses that kill bacteria in our microbiomes.
Bacteriophages, also known as phages, are harmless to human cells as they do not recognize them as their bacterial prey.
They work by hunting down bacteria and attaching themselves to the surface of a bacterial cell, before injecting viral DNA material into the cell.
The viral DNA then replicates inside the bacteria, sometimes by borrowing the DNA replication hardware of the bacteria.
Once enough new viruses have been created inside the bacterial cell, the cell then bursts to release the new viral particles.
All this takes just 30 minutes, meaning one virus can become many in a couple of hours.
Phage therapy
The ability of phages to take down bacteria had scientists pondering whether they could be used to treat bacterial infections in the early 20th century, but when antibiotics like penicillin came along, that research faded away.
But antibiotic-resistant strains of bacteria are now on the rise, with experts saying antibiotic resistance is one of the greatest medical challenges facing global communities.
As a result, scientists are racing to find new forms of antibiotic agents, putting phages back on the menu as agents to fight bacterial infections.
The advantages of phages lie in their effectiveness against every multi-resistant pathogen.
Phages are extremely precise in their elimination of bacterial strains — so much so that you don’t disturb the gut microbiome, as is the case with antibiotics.
In theory, then, phages could be a huge boon in our fight against antibacterial resistance.

What does the study show?
The new analysis focuses on the environmental dissemination of ARGs. With every 1% rise in PM2.5 pollution, antibiotic resistance increased between 0.5-1.9% depending on the pathogen — a link which has only intensified with time.
The researchers added that this airborne spread may have also caused premature deaths in India and China, among other countries in South Asia, North Africa and the Middle East which are population dense.
An average of 18.2 million years of life was lost in 2018 worldwide, resulting in an annual economic loss of $395 billion (more than Pakistan’s GDP) due to premature deaths.
The paper is unique in its scale and scope: global antibiotic resistance is driven by multiple factors, one being the “effect derived from the environment, which is poorly understood in relation to antibiotic resistance”.
The researchers collected data from 116 countries spanning almost two decades, to observe the link between rising PM2.5 and antibiotic resistance. The researchers also analysed other predictors, including sanitation services, antibiotic use, population, education, climate.
How is air linked to antibiotic resistance?
Antibiotic-resistant bacteria and genes travel through different pathways: food, soil, water, air, and even direct contact with sources such as animals.
The hypothesis is that ARGs, when emitted from, say, hospitals or livestock farming, could latch on to pollutant particles, which were found to contain “diverse antibiotic-resistant bacteria and antibiotic-resistance genes, which are transferred between environments and directly inhaled by humans, causing respiratory-tract injury and infection.”
When suspended in the environment or breathed into the lungs, the ARGs could enter the bacteria found in the human body and solidify its resistance to drugs. “PM 2.5 can facilitate the horizontal gene transfer of antibiotic-resistant genes between bacteria,” the research found.
PM2.5 contains a high concentration of antibiotic resistance-determinant genes, and these particles can travel far and wide due to wind speed, water evaporation, and dust transport.
ARGs are also more abundant in urban air particles than in sediment, soil or rivers, the analysis showed.
