Emergence of unusual G6P[6] rotaviruses in children, Burkina Faso, 2009-2010
Johan Nordgren, Leon W. Nitiema, Sumit Sharma, Djeneba Ouermi, Alfred S. Traore, Jacques Simpore, Lennart Svensson
To obtain more information about rotavirus (ROTAV) genotypes in Burkina Faso, we characterized 100 ROTAVs isolated from fecal samples of children with acute gastroenteritis in the capital city of Ouagadougou, during December 2009-March 2010. Of note, 13% of the ROTAV-positive samples, including those with mixed infections, were positive for th(...)

Understanding the interactions between artemisinin and cyclodextrins: spectroscopic studies and molecular modeling)
Hermine Zime-Diawara • Georges Dive • Géraldine Piel • Mansourou Moudachirou • Michel Frederich • Joëlle Quetin-Leclercq • Brigitte Evrard
Artemisinin extracted from Artemisia annua L.
proved to be currently, with its derivatives, the most effective
drugs against simple and severe malaria, and is also effective
on the chloroquine-resistant forms. The advantageous effect
of some cyclodextrins (CDs) on artemisinin solubilization
was demonstrated by different authors. The prese(...)

Artemisia annua is an asiatic plant with curative properties against malaria,
containing artemisinin. This active compound, and its derivatives are the last few
antimalarial drugs that remain effective against multidrug resistant strains of
Plasmodium falciparum. But they are very expensive and not accessible to poor
African countries.

An engineered Plasmodium falciparum C-terminal 19-kilodalton merozoite surface protein 1 vaccine candidate induces high levels of interferon-gamma production associated with cellular immune responses to specific peptide sequences in Gambian adults naturally exposed to malaria
C Bisseye, L M Yindom, J Simporé, W D Morgan, A A Holder, J Ismaili
The 19-kDa C-terminal region of merozoite surface protein 1 (MSP1(19)), a major blood stage malaria vaccine candidate, is the target of cellular and humoral immune responses in humans naturally infected with Plasmodium falciparum. We have previously described engineered variants of this protein, designed to be better vaccine candidates, but th(...)

Effectiveness of the Regular Implementation of the Mother to Child Transmission Plus (MTCT-Plus) Program in Burkina Faso, West Africa
Fabio Buelli, Virginio Pietra, Richard Fabian Schumacher, Jacques Simpore, Salvatore Pignatelli, Francesco Castelli and the ESTHER-Brescia Study Group
Since the 90s, many developing countries have introduced health strategies aimed at reducing Mother-to-Child transmission rate of HIV. These strategies (PMTCT – Prevention of Mother-to-Child Transmission) are based on (i) adequate counselling for HIV voluntary testing during antenatal care visits, (ii) single dose or a short antiretroviral the(...)

Hemoglobins S and C interfere with actin remodeling in Plasmodium falciparum-infected erythrocytes
Marek Cyrklaff, Cecilia P. Sanchez, Nicole Kilian, Cyrille Bisseye, Jacques Simporé, Friedrich Frischknecht, Michael Lanzer
The hemoglobins S and C protect carriers from severe Plasmodium falciparum malaria. Here, we found that these hemoglobinopathies affected the trafficking system that directs parasite-encoded proteins to the surface of infected erythrocytes. Cryoelectron tomography revealed that the parasite generated a host-derived actin cytoskeleton within th(...)
