CTX-M group 1 in birds, goats and water: One Health findings
A One Health study in the Kenyan Rift Valley found CTX-M group 1 genes in 14 of 79 screened bacterial isolates from migratory Little Stints, goats and water. All 13 bird and goat carriers were sampled in the pre-departure window, which points to local acquisition at shared freshwater hubs rather than import from the Arctic. The one water carrier came from an artesian borehole, not from the lake itself. Why this matters: ESBL-producing Enterobacterales beyond the clinic ESBL-producing Enterobacterales sit on the World Health Organization list of critical priority pathogens. ESBL stands for extended-spectrum beta-lactamase, the enzyme class that inactivates third-generation cephalosporins such as cefotaxime, ceftazidime and ceftriaxone, the workhorse…

Carbapenemase in poultry: blaNDM-5 found in a broiler farm
Carbapenemase in poultry production systems has now been documented in the United Arab Emirates for the first time. Screening 77 cecal samples from broiler farmhouses and slaughterhouses found three confirmed producers. One of them was a Klebsiella pneumoniae ST11 strain carrying blaNDM-5, a gene whose mobile backbone matches a human clinical isolate from India at more than 98 percent nucleotide identity. Why carbapenemase in poultry matters for One Health Carbapenems are the antibiotics clinicians reach for when everything else has failed. Carbapenem-resistant Enterobacterales sit on the World Health Organization critical-priority list, because they spread quickly and leave few treatment options behind. For years these organisms were treated as a hospital…

Closantel and Antibiotic Resistance: How a Sheep Dewormer Could Fight Superbugs
There’s a drug sitting in barns across the world that most human doctors have never heard of. It’s used to treat liver flukes in cattle and sheep, and it’s been around for decades. But researchers are now looking at this same drug—closantel—and wondering if it might help us fight one of the biggest threats to human health: antibiotic-resistant bacteria. The Problem Nobody Wants to Talk About Let me be direct: we’re losing the war against superbugs. The World Health Organization projects that antibiotic resistance could cause 10 million deaths every year by 2050. That number is staggering, and it’s not science fiction—it’s a conservative estimate based on current trends. Gram-negative…
