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…

Pseudomonas plecoglossicida Virulence Peaks in Cold Water
Ask a pond manager what makes a bacterial outbreak worse and you usually get the same answer. Warm water, heavy organic load, crowded nets. Fair enough. Bacteria grow faster in the heat, so summer feels like the season to worry about. For one species that instinct is simply wrong. Pseudomonas plecoglossicida virulence peaks at around 18 degrees C, far below the 28 degrees C where the bacterium grows fastest. A 2026 review pulled together the experimental work behind that inversion, and the numbers line up well enough that anyone running ayu, grouper, large yellow croaker, rainbow trout or barramundi should rethink when they watch their stock hardest. It is a…

38 of 39 Antibiotics Failed: Klebsiella in Fish Farms
Thirty-eight drugs out of thirty-nine did nothing. A 2026 study of farmed bullfrogs in central China ran a full susceptibility panel against a single isolate pulled from a sick animal, and exactly one compound came back with a susceptible reading. Polymyxin B, 17 mm zone. Ampicillin through meropenem, all resistant or intermediate. The bug was Klebsiella pneumoniae. If you run a fish or amphibian operation, that name probably has never come up in a meeting. Which is sort of the point. Multidrug-resistant Klebsiella pneumoniae in aquaculture stopped being a story borrowed from human medicine the moment it turned up in a production pond, killed animals under controlled conditions, and showed…
