“…Plasmodium species NAA assays have expanded to target additional gene sequences [including the P. falciparum stevor multigene family [69], mitochondrial DNA (mtDNA) [70], and telomere-associated repetitive element 2 (TARE-2) [71] sequences and P. vivax Pvr64 sequences [72] and mtDNA [70]. Assays targeting stevor, TARE-2 and Pvr64 are limited by their single species focus; 18S rRNA gene and mtDNA [20] assays are developed to identify all human malaria species]. Assay development focused on these sequences theoretically improves infection detection beyond assay formats that target 18S rRNA gene sequence due to increased copy number (stevor, 30-40 copies/parasite genome [69]; mt cytb, 30-100 copies/iRBC [70]; TARE-2,250 copies/parasite genome [71]).…”

“…These SMI have been validated and summarized in numerous excellent reviews [ ]. Furthermore, regional and national studies regularly report SMI in many malaria-endemic regions when diagnoses by microscopy/RDTs have been coupled with more sensitive and specific nucleic acid amplification (NAA) strategies (14 manuscripts in 6 months of 2015 alone: AFRO -6 [19][20][21][22][23][24]; EMRO -1 [25]; SEARO -2 [26,27] [31]). Although microscopy and RDTs help to achieve goals of malaria control, and RDTs have helped to significantly reduce widespread overtreatment with antimalarial drugs [32], these surveys indicate that malaria elimination (the absence of all parasites) requires more sensitive infection detection strategies to prevent transmission [17 && ].…”

“…Este método presenta una alta sensibilidad, equivalente a 94,6%; superando otras pruebas, debido a que puede detectar más de 0,002 parásitos/μL de sangre y la presencia de coinfección, es decir, más de una especie de Plasmodium; sin embargo su especificidad es del 88,3% [30,39]. Una de las ventajas en comparación con los otros métodos diagnósticos, es que se demostró que se puede detectar la enfermedad en el estado pre-eritrocito al detectar el ADN del parásito mediante una PCR en la materia fecal de los pacientes y en sangre periférica, debido a las grandes inoculaciones del mosquito [40].…”

“…Se ha utilizado principalmente PCR anidada, que detecta la subunidad 18S del ácido ribonucleico ribosómico (ARNr) del Plasmodium, este tipo de PCR ha servido de estándar para la comparación con otros tipos de PCR como PCR en tiempo real (qPCR), puesto que este ha tenido baja eficiencia a la hora de realizar la electroforesis [39].…”
