Deer Ticks & Lyme Disease
Lyme disease is caused by a bacterium carried by the deer tick. When
an infected deer tick attaches to a person (host) long enough to
take a full blood meal, the bacteria could be transferred to the
host's blood and cause illness.
Lyme disease is the most common reportable illness within the health
district. This disease is one of three diseases caused by the bite
of an infected deer tick (Ixodes scapularis). The tick carries a
type of bacterium called Borrelia burgdorferi which is responsible
for lyme disease. The two other less common diseases carried by deer
ticks are human babesiosis and human granulocytic ehrlichiosis. The
deer tick is capable of co-carrying these disease agents. Another
common tick in Connecticut, the dog tick, (Dermacentor variabilis)
is not capable of carrying the lyme disease bacterium.
The health district offers the service of tick testing by the
Connecticut Agricultural Experiment Station. If you or a family
member finds an attached tick, after removal, you may bring the tick
to the health district. After an initial confirmation that the tick
is a deer tick, it will be forwarded to the Ag Station for
definitive identification and for the presence of the lyme disease
The health district has educational information on lyme disease as
well as backyard tick control. The Connecticut Agricultural
Experiment Station (www.caes.state.ct.us) is another excellent
resource for tick information and control.
