DEER TICK 001

A photomicrograph of a deer tick, nymph, Ixodes dammini. Ixodes means "hard ticks". Deer ticks can be carriers of the bacteria, Borrelia burgdorferi, which causes Lyme's disease.  Lyme's disease was named after Lyme, Connecticut, USA where it was first identified in 1975.  In 1978 Allen Steere discovered that it was a tick borne disease, it wasn't until 1981 when the bacteria was identified by Willy Burgdorfer.  Ticks which carry diseases are also known as vectors. Lyme disease is the most common tick borne disease in North America.  Symptoms include fever, headache, fatigue, depression with a characteristic circular skin rash.  Untreated, Lyme's disease can become dangerous involving the joints, heart and central nervous system which can become disabling.  NOTE:  Original magnification was 6X on a 23mm x 35mm slide or 34X on a 5x7 inch print.
