What's the difference between PD fleas, rabbit fleas, or coyote fleas?.......
inquiring minds......
Huntsman, good question.
There are thousands of different species of flea's. During the 2004-2007 outbreak, primarly 3 species were found here in Colorado. Two were P-dog specialist, (Oropsylla hirsuta and Oropsylla tuberculata cynomuris) and the third was a generalist, (Pulex simulans).Pulex simulans is more closely related to the flea's most commonly on humans, (Pulex irritans), so it's more likely that simulans is the vector bridging the gap between p-dogs and humans.
In contrast, rabbit fleas are Spilopsyllus Cuniculi, and belong to an entirely different branch of the flea family.
