Influence Of Tick Transmission On The Host Response To Rickettsial Infection, Soma Chowdhury
Influence Of Tick Transmission On The Host Response To Rickettsial Infection, Soma Chowdhury
LSU Master's Theses
Several members of the spotted fever group (SFG) of Rickettsia are transmitted to the host through infected ixodid (hard) ticks, which can serve as both vectors and reservoirs. Multiple studies have demonstrated that ticks secrete proteins into the bite site of the host that suppress innate and adaptive immune responses. While this suppression of immune responses is beneficial to the tick, it may also be beneficial to the transmitted Rickettsia. We hypothesize that Rickettsia utilize the tick’s ability to alter the host immune response at the tick feeding site to successfully establish infection. In the current study, we analyzed how …
Quantitative Real-Time Polymerase Chain Reaction (Qpcr) Assay As A Molecular Tool To Assess Rickettsial Replications In Tick Hosts, Andrea S. Zanetti
Quantitative Real-Time Polymerase Chain Reaction (Qpcr) Assay As A Molecular Tool To Assess Rickettsial Replications In Tick Hosts, Andrea S. Zanetti
LSU Master's Theses
During the past century, many species of the Spotted Fever Group Rickettsia (SFGR)have been described, especially, through the introduction of a variety of molecular techniques applied to detect rickettsiae inside of their host. In this study we developed a quantitative realtime polymerase chain reaction (qPCR) assay (1) to characterize the growth and the distribution of a SFGR of unrecognized pathogenicity in naturally infected Amblyomma americanum ticks during physiological events; and (2) to terminate the influence of the host cell specificity in the replication patterns of recognized and unrecognized SFGR during a reciprocal rickettsiae challenge in both mammalian and tick cell …
