Direct injection of Amblyomma americanum ticks with Cytauxzoon felis. [PDF]

Ticks Tick Borne Dis, 2022
Cytauxzoon felis is a tick-borne hemoprotozoan parasite that causes life-threatening disease in domestic cats in the United States. Currently, the platforms for C. felis research are limited to natural or experimental infection of domestic cats. This study aims to develop an alternative model by infecting Amblyomma americanum ticks with C.

Disease Agents inAmblyomma americanumfrom Northeastern Georgia [PDF]

Journal of Medical Entomology, 2004
Amblyomma americanum (lone star tick) is known or suspected to vector several organisms that are implicated as human pathogens, including Ehrlichia chaffeensis, E. ewingii, and Borrelia lonestari. These three agents have also been detected in white-tailed deer (Odocoileus virginianus). Because northeastern Georgia has a high abundance of both lone star
