*Puberty onset (transition from Tanner stage I to Tanner stage II) occurs for girls at a median age of 10.5
(+/- 2) years. There is evidence that it may occur up to 1 year earlier in obese girls and in African
American girls. Progression through Tanner stages is variable. Tanner stage V (adult) should be reached
by age 18.

Lyme Disease (Borrelia burgdorferi), Molecular Detection, PCR
Clinical Information: Lyme disease is a multisystem and multistage infection caused primarily by 3
species of tick-borne spirochetes in the Borrelia burgdorferi sensu lato genogroup. These spirochetes
include Borrelia burgdorferi sensu stricto (North America and Western Europe), Borrelia afzelii (Central
and Western Europe and Russia), and Borrelia garinii (Europe, Russia, and northern Asia). Endemic areas
for Lyme disease in the United States correspond with the distribution of 2 tick species, Ixodes scapularis
(Northeastern and Upper Midwestern US) and Ixodes pacificus (West Coast US). In Europe, Ixodes
ricinus transmits the spirochete. Lyme disease is the most commonly reported tick-borne infection in
