Despite a successful program to eliminate cattle fever ticks during the first half of the 20th century, these ticks still manage to cross the Mexican border into Texas. A new vaccine developed by Agricultural Research Service (ARS) scientists with the U.S. Department of Agriculture (USDA) could control these pests and help prevent a reinfestation of cattle fever ticks in the United States. These ticks can transmit pathogens that cause bovine babesiosis and anaplasmosis—diseases that can kill cattle.

Botulism, the sometimes deadly illness commonly associated with botched home-canning or other stored-food mishaps, has a new face. According to U.S. Department of Agriculture (USDA) molecular biologist Robert M. Hnasko, botulism today is both a food safety and a homeland security concern because bioterrorists could—using the natural toxins that cause botulism—make everyday foods and beverages deadly. The nerve-damaging toxins, called neurotoxins, are produced by a common soil-dwelling bacterium, Clostridium botulinum, and several of its close relatives.
Hnasko works for the Agricultural Research Service (ARS), USDA's chief intramural scientific research agency.
