Pathogen: Lyme Disease
General Info:: Lyme disease is the most common tick-borne
disease in the Northern Hemisphere.
Vector: The black legged deer tick
Type of Pathogen: Bacteria
Strategy: It lives in the belly of a tick and passes into a human
after taking a blood meal
Path of Transmission: It is only passed from tick to human.
Humans usually get a bulls-eye shaped rash following the
transmission.

Pathogen: Cholera
Type of Pathogen: Bacteria
General Info: diarrheal illness caused by infection of the intestine
with the bacterium Vibrio cholerae.
Symptoms: profuse watery diarrhea, vomiting, and leg cramps. In
these persons, rapid loss of body fluids leads to dehydration and
shock. Without treatment, death can occur within hours.
Strategy: travels through and releases toxins in blood
Path of Transmission: contaminated water, food
