Bacterial patch promises to defeat the most fearsome infections
Scientists have created a patch with predatory Bdellovibrio bacteriovorus bacteria to treat diabetic ulcers and combat Pseudomonas aeruginosa.

Scientists from the National Polytechnic Institute of Central America have developed a patch to treat antibiotic-resistant infections caused by diabetic foot ulcers. Such ulcers are non-healing wounds that can easily become a haven for dangerous bacteria. The possible outcome is limb amputation.
The active agent in the patch is the predatory gram-negative bacterium Bdellovibrio bacteriovorus. It can suppress the growth of other microorganisms. According to the developers, these bacteria quickly remove dangerous pathogens from the wound. Moreover, the bacteria work against the most resistant pathogens, including Pseudomonas aeruginosa (the blue-pus bacillus). The patch is currently at an experimental stage of development. In the near future, its creators hope to move on to clinical trials.
According to the scientists, the patch's effect should vary depending on the severity of the infection. For obvious reasons, the patch will not work at the stage of gangrene development. But at earlier stages of infection development, the patch could be combined with antibiotics.
