A) most often cause systemic infections.
B) are best described as ectoparasites.
C) are classified as helminths.
D) cause mycotic infections.

Accepted Answer

Biting flies, fleas, and ticks are all examples of ectoparasites, which are parasites that live on the outer surfaces of their hosts (i.e. the skin or hair) rather than inside their bodies. These parasites can transmit diseases to their hosts, but they do not typically cause systemic (i.e. internal) infections. Helminths are a different type of parasite that live inside their hosts, such as intestinal worms, and are not directly related to biting flies, fleas, or ticks. Mycotic infections are caused by fungi, not ectoparasites.
