District-Level Trends in Veterinary Antimicrobial Prescribing in a Resource-Limited Setting: Evidence from Mongar, Bhutan (2023–2026)
This retrospective study of 3.5 years of veterinary data from Mongar, Bhutan, reveals that antimicrobial prescribing rates remained stable with a seasonal peak during the monsoon, while highlighting significant variations in drug class selection based on animal species and facility type, with Tetracyclines and Penicillins being the most commonly prescribed.

Imagine a world where tiny, invisible warriors called bacteria are constantly trying to outsmart the medicines we use to stop them. These medicines, known as antimicrobials, are like the shields and swords of the medical world, used to heal sick animals and people. But here's the tricky part: if we use these shields too often or in the wrong way, the bacteria learn how to break through them. This is called "antimicrobial resistance," and it's a bit like a game of chess where the bacteria keep learning new moves to beat us. In many places, especially those with fewer resources, we don't have a clear map of how these medicines are being used in the animal world. Without that map, it's hard to know if we are playing the game wisely or if we are accidentally helping the bacteria win. This is why scientists are so eager to look at the records of how doctors and vets prescribe these drugs, hoping to find patterns that can help us protect our future health.
Now, let's zoom in on a specific corner of this puzzle: a district called Mongar in Bhutan. Two researchers, Narayan and Cheda, decided to play detective with a massive digital treasure chest of veterinary records. They didn't just look at a few notes; they dug into the official computer system used by the District Veterinary Hospital and 16 smaller extension centers across the district. They wanted to see what happened between January 2023 and June 2026—a period of three and a half years. Think of it like watching a movie of animal healthcare in slow motion, frame by frame, to see if the story of medicine use was changing, staying the same, or going off the rails.
What they found was a story of stability, but with some very interesting twists. First, the big picture: the amount of antimicrobial medicine prescribed didn't really go up or down over those years. It was like a steady heartbeat, not a racing pulse. They looked at over 17,000 medical records and found that about 6% of them involved giving an antimicrobial drug. If you look at it from the perspective of individual animal visits, about 11.5% of the time, a vet decided to prescribe one of these drugs. The researchers ran the numbers through a statistical microscope and found no significant trend toward more or less use, even when they accounted for the changing seasons.
However, the story gets much more colorful when you look at who got the medicine and what kind they got. It turns out that the type of animal mattered a lot. Cows (bovines) were the stars of the show, making up nearly 73% of all the prescriptions. It makes sense, as there are just way more cows in the district than cats or dogs. But here's the fun part: the medicine given to a cow was almost never the same as the medicine given to a cat or a dog. It was like two different pharmacies operating in the same building. For cows, the vets mostly reached for Tetracyclines (about 39.5% of the time) and Penicillins (35.3%). These two types of drugs made up three-quarters of everything prescribed. But for cats and dogs, the vets leaned more heavily on Penicillins and other types, rarely using Tetracyclines.
The plot thickens when you look at where the animal was treated. The main District Veterinary Hospital and the smaller rural extension centers seemed to have different "flavors" of prescribing, even when they were treating the same type of animal, like a cow. The main hospital loved Penicillins, while the rural centers were much more likely to use Sulphonamides and Aminoglycosides. The researchers checked to make sure this wasn't just because the rural centers saw different kinds of cows, but the difference held up. It suggests that even though everyone has the same rulebook, the doctors at different locations are following it in slightly different ways.
There was also a very clear rhythm to the story. The number of prescriptions didn't stay flat all year; it had a big, predictable spike. Every single year, from June to August, the number of prescriptions jumped up significantly. This perfectly matches the monsoon season in Bhutan, a time of heavy rain. The researchers suggest that the wet, muddy conditions of the monsoon probably lead to more infections in animals, like foot rot or wounds getting dirty, which is why the vets had to prescribe more medicine during those months. It's like how traffic jams happen every day at 5 PM; the rain just creates a "medicine rush hour" for animals.
So, what's the takeaway? The paper doesn't claim to have solved the mystery of antimicrobial resistance, nor does it say that the current situation is perfect. Instead, it paints a clear, stable picture of how things are right now in Mongar. The use of these drugs isn't spiraling out of control, but there are clear patterns: cows get most of the drugs, the type of drug depends heavily on the animal and the location, and the rainy season brings a surge in need. The researchers suggest that if we want to manage these medicines better in the future, we should focus on making sure all the vets, whether in the big city hospital or the small rural center, are following the same guidelines. They also suggest that we should be extra prepared with supplies and advice right before the monsoon hits, rather than spreading our efforts evenly all year round. It's a small but vital step in understanding how to keep our animal friends—and the medicines we rely on—healthy for the long haul.
