Abstract
Several assay methods are in use for monitoring the drug sensitivity of malaria parasites and screening new antimalarial drugs. Plasmodium lactate dehydrogenase (pLDH) and SYBR Green I in vitro assays were used to evaluate the drug efficacy of Chloroquine, Artemisinin and Azadirachta indica silver nano particles against Plasmodium falciparum 3D7 strain. The half-maximal inhibitory concentration (IC50) of each compound was estimated with non-linear regression model – dose-response analysis. The consistency between two methods was analysed with Cohen's kappa coefficient, interclass correlation and Bland-Altman plots. No statistical difference was found between IC50 values determined by both assays (p = 0.714). The proportion of resistant isolates to chloroquine according to SYBR green I (43.48%) and pLDH (34.78%) assays were similar (z = 0.302; p = 0.762) with significant concordant between methods (k = 0.819, p < 0.001). The results of pLDH Qualisa assay was comparable with classic SYBR green I assay and can be potentially useful in antimalarial drug efficacy surveillance.
