Clinical Features:
Most ticks do not elicit any response from their host while feeding.  Ticks in the genera Dermacentor and Ixodes have been implicated in tick paralysis, a condition characterized by an acute, ascending, flaccid motor paralysis that can result in death if the tick is not removed.  The condition is believed to be caused by toxins in the ticks' saliva.

Laboratory Diagnosis:
In most cases, ticks need only to be identified to the genus level to rule-out potential vectors of disease.  Ticks are best identified by examining non-engorged adults.  Nymphs may lack certain diagnostic features and in engorged individuals, certain features (festoons, anal groove) may be difficult to see.  The geographic location of the tick can also be important for accessing the public health importance.

Diagnostic findings

• Microscopy

Treatment:
There is no specific treatment for ticks specifically, outside of the complete removal of the parasite from the skin.  Ticks are best removed by firmly grasping the mouthparts with fine forceps, and gently pulling away at a 45° angle.  Vaseline and other ointments should not be used, as they cause the ticks to vomit, possibly inoculating the host with a pathogen.  The best way to control ticks, and reduce the chances of acquiring tick-borne diseases, is habitat management (decreasing humidity and harborage that support egg-laying and sheltered areas).
