Estandarización de una reacción en cadena de la polimerasa en tiempo real (qPCR) para la detección de Strongyloides stercoralis en muestras de materia fecal

Abstract: Introducción: el diagnóstico de estrongiloidiasis se realiza de rutina en los laboratorios clínicos; sin embargo, su detección se dificulta debido a la baja excreción parasitaria y la baja sensibilidad de las pruebas parasitológicas empleadas. Objetivo: diseñar y estandarizar una PCR en tiempo real (qPCR) para la detección de ADN de Strongyloides stercoralis en muestras de materia fecal. Materiales y métodos: se establecieron las condiciones de qPCR y se evaluaron: a) la especificidad analítica mediante anális… Show more

“…The threshold cycle (Ct) value obtained with the standardized qPCR was less than or equal to 29.99 in the positive samples. A Ct value between 30.00 and 34.99 was considered indeterminate, assuming that only samples with a very low parasitic load would show those values 27 .…”

“…Each dilution was carried out with two replicates, two negative controls, and two no-template controls. These dilutions were also compared with end-point PCR to determine the level of LOD between both techniques [ 36 ]. The number of copies of the serial dilutions was calculated with an equation described by Shirima et al [ 37 ].…”
