CATERPILLAR-INDUCED ABORTIONS IN MARES.

New research is underway in the Hunter Valley to try to reduce the number of abortions in horses caused by a species of caterpillar.University of Queensland researcher Julianne Farrell is carrying out field studies at several Upper Hunter studs, focussing on the hairs from the processionary caterpillar. Studs have addressed the problem by keeping mares away from the caterpillar and its nest.Ms Farrell said the racing industry is hoping the three-year study sheds light on the issue."That's why the racing industry has funded this project," she said. When service to a highly prized stallion is so expensive, you don't want to lose a foal halfway through the pregnancy."So it's in everyone's best interests that we sort out how we can possibly keep the mares and the caterpillars apart."Ms Farrell said controlling the caterpillar is proving challenging."What we'd like to provide is someway of keeping these caterpillars and the pregnant mares apart," she said."To keep the breeders and the stud owners in the Hunter Valley, and elsewhere where there are lots of thoroughbreds studs, happy. But it's not just the thoroughbreds affected - it's all sporting and performance horses that can also be affected."Scone vet Cameron Collins said the caterpillar has wreaked havoc during breeding seasons."We believe that processionary caterpillar related abortions may be responsible for up to 20 to 25 per cent of the abortions we see," he said. "What we find is the caterpillars live in nests in the trees," he said."The nest grows as the caterpillars grow, and shed their skin, full of caterpillar excretions."If that nest is disturbed, all of that exoskeleton material is distributed across the paddock, then the horses can be exposed to the contents of those nests, and that's when we think the problem occurs."It's a matter of identifying those nests and then disposing of them safely.

Antibiotic-resistant gene discovered in soil bacterium that commonly infects foals.

Rhodococcus equi is one of the most important causes of disease in young horses,A research team based in the University of Georgia College of Veterinary Medicine has discovered a novel gene—erm(46)—that confers antibiotic resistance in Rhodococcus equi, a soil-dwelling baterium that commonly infects foals and causes opportunistic infections in immunocompromised people, according to a release from the university. R. equi, a gram-positive intracellular pathogen, is one of the most important causes of disease in foals between 3 weeks and 5 months of age.
