Abstract:
Heartworm antigenemia was evaluated and found to be negative in 1010 dogs in Northeastern Colorado that were examined at the Colorado State University Veterinary Teaching Hospital. The estimated prevalence of canine heartworm for the native Northeastern Colorado population was determined to be 0.3% and is similar to the prevalence reported 10 years ago in the same area. We conclude there has not been an increase in prevalence of heartworm in the last 10 years; because of the low prevalence, there is no need for routine testing or testing and prophylaxis in the study area at this time.
