Chemoresistant P. falciparum malaria emerged in South Sahara Africa during 1978 and is now more than half of the imported malaria in F. Houphouet-Boigny Hospital in Marseilles (France), consequently the annual number of malaria cases has doubled as compared to the previous years. In our study of 47 chemoresistant malaria cases, collected in 1985-1986-1987, mostly contracted in French-speaking Africa, residents and travellers were both equally affected. Curative treatment was quinine IV for severe malaria (34%), sulfadoxine-pyrimethamine (46.8%), and mefloquine (51%).

Alba domain-containing proteins are ubiquitously found in archaea and eukaryotes. By binding to either DNA, RNA, or DNA:RNA hybrids, these proteins function in genome stabilization, chromatin organization, gene regulation, and/or translational modulation. In the malaria parasite , six Alba domain proteins PfAlba1-6 have been described, of which PfAlba1 has emerged as a "master regulator" of translation during parasite intra-erythrocytic development (IED).

Significance: Developments of anti-gametocyte drugs have been delayed due to insufficient understanding of gametocyte biology. We report a systematic workflow of data processing algorithms to quantify changes in the absorption spectrum and cell morphology of single malaria-infected erythrocytes. These changes may serve as biomarkers instrumental for the future development of antimalarial strategies, especially for anti-gametocyte drug design and testing.
