African origin of the malaria parasite Plasmodium vivax.
Get PDFPlasmodium vivax is the leading cause of human malaria in Asia and Latin America but is absent from most of central Africa due to the near fixation of a mutation that inhibits the expression of its receptor, the Duffy antigen, on human erythrocytes. The emergence of this protective allele is not understood because P. vivax is believed to have originated in Asia. Here we show, using a non-invasive approach, that wild chimpanzees and gorillas throughout central Africa are endemically infected with parasites that are closely related to human P. vivax. Sequence analyses reveal that ape parasites lack host specificity and are much more diverse than human parasites, which form a monophyletic lineage within the ape parasite radiation. These findings indicate that human P. vivax is of African origin and likely selected for the Duffy-negative mutation. All extant human P. vivax parasites are derived from a single ancestor that escaped out of Africa

Tipificación del antígeno Duffy como método indirecto para identificar individuos asintomáticos de malaria
No full textEn países considerados endémicos de malaria a pesar de las estrategias realizadas anualmente para el control y erradicación de esta enfermedad existen brotes aislados de malaria debido probablemente a portadores asintomáticos, presencia de individuos con fenotipo Duffy negativo o movimientos poblacionales. El sector “50 casas” de la provincia de Esmeraldas-Ecuador reúne todas estas características por lo que el objetivo de esta investigación fue determinar la presencia del fenotipo Fy(a-b-) y su relación con el Plasmodium vivax. Se realizó una encuesta a cada miembro de las familias participantes y luego de aceptado y firmado el consentimiento informado se tomaron muestras sanguíneas para la realización de pruebas serológicas en búsqueda de anticuerpos y antígenos de P. vivax, fenotipificación del sistema Duffy y pruebas de PCR en tiempo real para la determinación de ADN de Plasmodium vivax y P. falciparum. Los resultados demostraron que existe una asociación estadísticamente significativa entre el fenotipo Duffy y malaria por P. vivax (p<0,05). Ante esta situación los organismos de control deberán proponer nuevas estrategias para la detección de portadores asintomáticos y medidas preventivas para evitar nuevos brotes de malaria, así como determinar si P. vivax ha encontrado un nuevo mecanismo de invasión en individuos portadores del fenotipo Fy(a-b-)
