Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Electronic Theses and Dissertations
Despite efforts to decrease the global health burden of malaria, infections with Plasmodium species continue to cause over 200 million episodes of malaria each year which resulted in 405,000 deaths in 2018 [1]. One complication of malaria is increased susceptibility to invasive bacterial infections. Plasmodium infections impair host immunity to non-Typhoid Salmonella (NTS) through activities of heme oxygenase I (HO-I) )-induced release of immature granulocytes and myeloid cell-derived IL-10. Yet, it is not known if these mechanisms are specific to NTS. We show here, that Plasmodium yoelii 17XNL (Py) infected mice had impaired clearance of systemic Listeria monocytogenes (Lm) during …

Methods To Identify And Develop Drugs For Cryptosporidiosis, Rajiv Satish Jumani
Graduate College Dissertations and Theses
Cryptosporidiosis is a common diarrheal disease caused by intestinal infection with the apicomplexan parasite Cryptosporidium, in humans usually either with C. hominis or C. parvum. Unfortunately, given a large burden of disease in children and immunocompromised people like AIDS patients, the only currently approved treatment, nitazoxanide, is unreliable for these patient populations. To address the urgent need for new drugs for the most vulnerable populations, large phenotypic screening efforts have been established to identify anti-Cryptosporidium growth inhibitors in vitro (hits). However, in the absence of a gold standard drug, the in vitro and in vivo characteristics that should be used …
Altered Intraerythrocytic Development Phenotypes Of Artemisinin-Resistant Plasmodium Falciparum Confer A Fitness Advantage, Amanda Hott
USF Tampa Graduate Theses and Dissertations
Resistance to artemisinin combination therapies (ACTs) has emerged in southeast Asia threatening the most widely used treatment against antimalarial-resistant Plasmodium falciparum worldwide. Artemisinin resistance has been associated with a reduced rate of parasite clearance following treatment with an ACT and is attributed to increased survival of ring-stage parasites. Single nucleotide polymorphisms (SNPs) in kelch gene (K13) has been associated with delayed in vivo clearance half-life of artemisinin-resistant P. falciparum and is the only known molecular marker of resistance. The absence of reliable in vitro phenotypes for artemisinin resistance has limited our understanding of the resistance mechanism(s) and fitness costs, therefore …
