Host Species

In addition to the domestic dog, many other species can act as alternate hosts for Dirofilaria immitis. These species, known as alternate hosts, will also maintain blood levels of circulating microfilaria sufficiently high to act as reservoirs of infections for mosquito intermediate hosts.  Examples of  alternate hosts include:

*Although these species may constitute microfilaremic reservoirs, the length of the microfilaremia is  brief  compared to the other species.


Other vertebrates may act as aberrant or dead end hosts. These species may become infected from the bite of a vector mosquito. However,  they do not develop a microfilaremia because migrating Dirofilaria fail to reach sexual maturity.  Examples of these include:
