This service, called the Human Tick Test Kit Program, was initiated in 1989 in response to the threat of Lyme disease, and offered tick identification and immunofluorescent antibody testing for Borrelia burgdorferi Johnson, Schmid, Hyde, Steigalt and Brenner, the etiological agent of Lyme disease. Results of tick identification and analysis are then reported back to the tickbite patient’s health care provider. Army Center for Health Promotion and Preventive Medicine (USACHPPM), Aberdeen Proving Ground, MD, for identification and analysis. Ticks removed from military personnel, military dependents, and Department of Defense (DOD) civilian employees are sent by DOD medical personnel and clinics to the Tick-Borne Disease Laboratory of the U.S. Ongoing surveillance of the vector species of human diseases provides an additional estimate of human encounters with infected ticks, and testing ticks removed from humans may increase our knowledge of the vector status of tick species for transmitting tick-borne pathogens.Īmblyomma americanum, Dermacentor variabilis, Ixodes scapularis, tick-borne disease, rickettsioses, Lyme disease Different species of ticks transmit different pathogens, and most tick-borne diseases have similar early symptoms, therefore knowing the species and infection status of the tick enhances the physician’s ability to consider tick-borne agents as a potential cause of disease and recommend appropriate therapy. burgdorferi and one (2%) was positive for the agent of human granulocytic ehrlichiosis. Five of 24 (21%) Ixodes scapularis Say were positive for B. variabilis from Monroe County, WI, were tested for B. Restriction fragment-length polymorphism analysis indicated all were Rickettsia montana. Thirteen of 308 (4%) Dermacentor variabilis (Say) were PCR-positive for spotted fever group rickettsiae. Five (2%) appeared to be co-infected with both organisms. Thirty-three of 222 (15%) Amblyomma americanum (L.) DNAs produced amplicons of the expected size of Ehrlichia chaffeensis Anderson, Dawson & Wilson and 26/222 (12%) produced amplicons indicating Borrelia burgdorferi Johnson, Schmid, Hyde, Steigalt & Brenner. Army Center for Health Promotion and Preventive Medicine (USACHPPM) were tested for pathogens by polymerase chain reaction (PCR). In 1997, ticks removed from humans and received alive by the Tick-Borne Disease Laboratory of the U.S.
