MaHPIC Experiment 06: Quantitative Metabolomics from Macaca mulatta infected with Plasmodium knowlesi sporozoites to produce and integrate clinical, hematological, parasitological, omics, telemetric and histopathological measures of acute primary infection

ABSTRACT: Telemetry devices (DSI, model L11) with blood pressure sensors and electrocardiogram (ECG) leads were surgically implanted in four malaria-naive male rhesus macaques (Macaca mulatta), approximately five years of age. After a resting period of two weeks, physiological data that include activity, temperature, ECG, and blood pressure were continuously collected. Two weeks after activation of the telemetry implant, the macaques were inoculated intravenously with cryopreserved P. knowlesi Malayan strain salivary gland sporozoites, obtained from Anopheles dirus infected with parasites from the Pk1A+ clone and previously tested in E30 for their infectivity of macaques. The sporozoite stocks used were produced, isolated and cryopreserved at the Centers for Disease Control and Prevention, and then stored at Yerkes. After inoculation, the macaques were profiled longitudinally for clinical, hematological, parasitological, immunological, functional genomic, proteomic, and metabolomic measurements. The experiment was designed with pathology studies and thus terminal necropsies, which were scheduled at the log phase of the infections or at the peak of parasitemias. Capillary blood samples were collected daily for the measurement of complete blood counts, reticulocytes, and parasitemias. Capillary blood samples were collected every other day to obtain plasma for metabolomics analyses. Venous blood and bone marrow samples were collected at five timepoints for functional genomic, targeted proteomic, targeted metabolomics, and immunological analyses. Physiological data noted above were continuously captured via the implanted telemetry devices.
Within the MaHPIC, this project is known as 'Experiment 06'. This dataset was produced by Dr. Regina Cordy and Manoj Khadka at Emory University. To access other publicly available results from E06 and other MaHPIC Experiments, including clinical results (specifics on drugs administered, diet, and veterinary interventions), and other omics, visit plasmodb.org/plasmo/mahpic.jsp. This page will be updated as datasets are released to the public. The experimental design and protocols for this study were approved by the Emory University Institutional Animal Care and Use Committee (IACUC) and the MRMC Office of Research Protection Animal Care and Use Review Office (ACURO).
