Detection and pathological role of intestinal protozoa in children.

Introduction: Intestinal parasites are considered a growing public health problem, being protozoa the main cause of intestinal disease. The objective of our study is to compare the detection of intestinal protozoa by microscopy versus real-time PCR, as well as to determine the most prevalent protozoa in our environment in the paediatric population.

Method: An observational longitudinal study was carried out, both by microscopy and real time-PCR in stool samples from children (0- 15 years) received from April 2019 to March 2021.
