Four Plasmodium species cause malaria in humans, Plasmodium falciparum being the most widely studied to date. All Plasmodium species have paired club-shaped organelles towards their apical extreme named rhoptries that contain many lipids and proteins which are released during target cell invasion. P. falciparum RhopH3 is a rhoptry protein triggering(More)
This study describes the identification and characterisation of Pv38, based on the available genomic sequence of Plasmodium vivax and previous studies done with its Plasmodium falciparum homologue: Pf38. Pv38 is a 355 amino acid long peptide encoded by a single exon gene, for which orthologous genes have been identified in other Plasmodium species by(More)
Recently, Plasmodium vivax has been related to nearly 81% of malaria cases reported in Central America and the Mediterranean. Due to the difficulty of culturing this parasite species in vitro, most studies on P. vivax have focused on the identification of new antigens by homology comparison with P. falciparum vaccine candidate proteins. In this study, we(More)
This study describes the identification of the Plasmodium vivax rhoptry antigen Pv34 whose sequence was obtained based on homology comparison with the Plasmodium falciparum Pf34. The pv34 gene product was characterized by molecular biology and immunological techniques. Additionally, association of Pv34 to detergent-resistant microdomains (DRMs), expression(More)
Malaria caused by Plasmodium vivax is a major public health problem worldwide that affects 70-80 million people in the Middle East, Asia, Western Pacific, South America and the Caribbean. Despite its epidemiological importance, few antigens from this parasite species have been characterized to date compared to Plasmodium falciparum, due in part to the(More)
We report on a 13-year-old boy who displayed a chronic granulomatous inflammatory reaction of 5 years duration. The lesion was resistant to different antibiotic schemes; his routine laboratory tests and chest radiographs were normal. Teledermatologic consultation and histopathologic study of skin biopsy suggested scrofulodermal tuberculosis. Polymerase(More)
