Amblyomma Maculatum Immunomodulation In Mammalian Models Of Rickettsia Parkeri Rickettsiosis, Kaikhushroo Hormazd Banajee

LSU Doctoral Dissertations

Rickettsia parkeri is an emerging human pathogen and spotted fever group Rickettsia that is transmitted via Amblyomma maculatum (the Gulf Coast tick) in the United States. Since these ticks must feed for several days in order to molt to the next life cycle, they must be able to counteract the host immune response. Despite this fact, there have been few studies that evaluate the immunomodulatory effect of this vector and the resultant influence on rickettsial disease. The hypothesis of this research is that, if A. maculatum feeding modifies the host immune response, this immunomodulation will enhance disease caused by R. …
