Abstract

Burkholderia mallei is the causative agent of glanders, a zoonosis listed by the World Organization for Animal Health as of mandatory notification. In this work, a comparison of three qPCR protocols was made, two of them based on articles by other authors and one standardized in house, this last one aiming at a genomic region that does not exist in other species of the Burkholderia genus. All qPCRs showed high efficiency and good repeatability. However, reactions with Cq between 36 and 40 were considered suspicious and unreliable, requiring greater clinical criteria to analyze the results.
