HEARTWORM TREATMENT SHORTAGE!
Most dog owners understand the seriousness of keeping their dogs on heartworm preventative—and it’s even more important now because the only FDA-approved treatment Immiticide (Merial) is unavailable. Dogs diagnosed with heartworms instead are being managed with the recommendations from the American Heartworm Society .
It’s important that pet owners remain faithful and give preventive medication on the prescribed schedule, too. Just being a few days late may open a window for infection. But there have been a few cases where dogs became infected even though they were given preventative without fail. Researchers suspect that some heartworm populations become resistant to the drug—so a new study has been launched.
NEW DNA STUDY OF HEARTWORMS NEEDS SAMPLES
Dr. Mark Rishniw, a genetic researcher at Cornell University requests veterinary practitioners from across the United States collect and send to him blood samples containing microfilaria and/or adult heartworms. A genetic survey hopefully will offer insight into the drug resistance issues being described. Veterinarians can email or call Dr. Rishniw for additional information at email@example.com or 916-275-1650.
