Bayer Animal Health has received a conditional license from the USDA for a vaccine for Neosporosis, a disease causing abortions in cattle. "We are very excited to provide the first and only vaccine to aid in the reduction of abortion due to neosporosis," said Paul Loney, Bayer's Livestock Product Manager. "Neosporosis is one of the leading diagnosed causes of abortions in cattle, especially diary cattle, and has been reported to cost the California dairy industry an estimated $35 million annually." Upon receiving approval from the USDA, Bayer is required to obtain authorization from individual states to sell the product. According to a Bayer news release, the new vaccine is expected to be available to veterinarians and cattle producers soon. Neosporosis is not new, but only recent testing methods have made it possible for cattle producers to identify the disease in their herds. Currently, more than 33 states have reported cases of neosporosis in cattle. Within one year of its identification in 1988, Neospora caninum infections were found to cause abortions and neonatal paralysis in animals in the United States and England. It is now the major diagnosed cause of abortion in the California diary industry, the Netherlands, Scotland, New Zealand and Australia. "Bayer's ability to offer such an important new tool for veterinarians and cattle producers around the country is also due to the cooperation we have received from other leading researchers within the industry," added Loney. Neosporosis is caused by the protozoan parasite Neospora caninum. Although dairy cattle appear to be at greatest risk for infection, there are reports of abortions caused in beef cattle by Neospora caninum as well. This vaccine is the first of its kind available to prevent neosporosis in cattle. |
