Broad Antibacterial Spectrum

ABSTRACT Tigecycline is a novel glycylcycline antibiotic with a broad antibacterial spectrum. Tigecycline was tested with 66 clinical isolates of Plasmodium falciparum from Bangladesh using the histidine-rich protein 2 in vitro drug susceptibility assay. The 50% and 90% inhibitory concentrations of tigecycline were 699 (95% confidence interval, 496 to 986) and 5,905 nM (4,344 to 8,028). Tigecycline shows no activity correlation with traditional antimalarials and has substantial antimalarial activity on its own.

In Vitro Drug Susceptibility

In vitro cultivation of Plasmodium falciparum has been extremely useful in understanding the biology of the human malaria parasite as well as research on the discovery of new antimalarial drugs and vaccines. A chemically defined serum-free medium supplemented with lipid-rich bovine serum albumin (AlbuMAX I) offers the following advantages over human serum-supplemented media for the in vitro culture of P. falciparum: 1) improved growth profile, with more than a 2-fold higher yield of the parasites at any stage of the growth cycle; 2) suitability for in vitro antimalarial screening, as the parasites grown in AlbuMAX and human serum-supplemented media show similar sensitivity to standard and novel antimalarials as well as natural product extracts in the in vitro drug susceptibility assays; and 3) DNA microarray analysis comparing the global gene expression profile of sorbitol-synchronized P. falciparum trophozoites grown in the 2 different media, indicating minimal differences.

ABSTRACT The drug resistance profiles of Plasmodium falciparum isolated from four regions in Kenya were analyzed for drug resistance profiles. We observed variability in resistance to a broad range of antimalarial drugs across Kenya as determined from in vitro drug susceptibility screening and genotyping analysis.
