Assessment and continued validation of the malaria SYBR green I-based fluorescence assay for use in malaria drug screening.
Several new fluorescence malaria in vitro drug susceptibility microtiter plate assays that detect the presence of malarial DNA in infected erythrocytes have recently been reported, in contrast to traditional isotopic screens that involve radioactive substrate incorporation to measure in vitro malaria growth inhibition. We have assessed and further characterized the malaria SYBR Green I-based fl...
متن کاملAssessment of malaria in vitro drug combination screening and mixed-strain infections using the malaria Sybr green I-based fluorescence assay.
Several drug development strategies, including optimization of new antimalarial drug combinations, have been used to counter malaria drug resistance. We evaluated the malaria Sybr green I-based fluorescence (MSF) assay for its use in in vitro drug combination sensitivity assays. Drug combinations of previously published synergistic (atovaquone and proguanil), indifferent (chloroquine and azithr...
متن کاملLow Parasitemia in Submicroscopic Infections Significantly Impacts Malaria Diagnostic Sensitivity in the Highlands of Western Kenya
Asymptomatic malaria infections represent a major challenge in malaria control and elimination in Africa. They are reservoirs of malaria parasite that can contribute to disease transmission. Therefore, identification and control of asymptomatic infections are important to make malaria elimination feasible. In this study, we investigated the extent and distribution of asymptomatic malaria in Wes...
متن کاملFlow Cytometric Enumeration of Parasitemia in Cultures of Plasmodium falciparum Stained with SYBR Green I and CD235A
A flow cytometric (FACS) detection method for Plasmodium falciparum cultures (P. falciparum) was developed using SYBR Green I and CD235A and compared against the Giemsa stained microscopic examination. The cultured P. falciparum were spiked into red blood cells (RBCs) to yield parasitemia, ranging from 0.01% to 22.0%. FACS analysis demonstrated a clear separation between P. falciparum infected ...
متن کاملA duplex SYBR Green I real-time quantitative PCR assay for detecting Escherichia coli O157:H7.
PCR and hybridization assays are widely used for the detection and identification of Escherichia coli serogroups and serotypes. We used these techniques for the detection of E. coli O157:H7, a dominant serogroup among E. coli strains that are considered major public health problems worldwide. We developed a quantitative PCR assay using SYBR Green I, based on the published sequences of the rfbE ...
