Amino acid dimorphism and parasite immune evasion: cellular immune responses to a promiscuous epitope of<em> Plasmodium falciparum</em> merozoite... (Publications)
Like most other surface-exposed antigens of Plasmodium falciparum, the leading malaria vaccine candidate merozoite surface protein (MSP)-1 contains a large number of dimorphic amino acid positions. Th
Tuberculosis in Salvador, Brazil: costs to health system and families (Publications)
OBJECTIVE: Tuberculosis is one the greatest causes of mortality worldwide, but its economic effects are not well known. This study had the objective of estimating the costs to the public and private h
Prenatal farm exposure is related to the expression of receptors of the innate immunity and to atopic sensitization in school-age children (Publications)
BACKGROUND: There is increasing evidence that environmental exposures determining childhood illnesses operate early in life. Prenatal exposure to a farming environment through the mother might also pl
8,8-dialkyldihydroberberines with potent antiprotozoal activity (Publications)
Semisynthetic 8,8-dialkyldihydroberberines (8,8-DDBs) were found to possess mid- to low-nanomolar potency against Plasmodium falciparum blood-stage parasites, Leishmania donovani intracellular amastig
<em>In vivo</em> and <em>in vitro</em> sensitivity of <em>Fasciola hepatica</em> to combinations of triclabendazole and artesunate, artemether or OZ78 (Publications)
Triclabendazole resistance is continually documented from livestock and hence new treatment strategies for F. hepatica infections are needed. We investigated the effect of combinations with triclabend
Clonal groupings in serogroup <em>X Neisseria meningitidis</em> (Publications)
The genetic diversity of 134 serogroup X Neisseria meningitis isolates from Africa, Europe, and North America was analyzed by multilocus sequence typing and pulsed-field gel electrophoresis. Although
