note = "Blastocystis spp. it is an anaerobic protozoan that has a
worldwide distribution. It is considered one of the most
frequently eukaryotic parasites found in human stool
samples, but it has not been until the last decades that
Blastocystis spp. has been shown to be a protozoan,
although it is only in recent years that it has been known
the biology of this microorganism in a in more detailed
way. It is described that frequency is higher in developing
countries, probably indicating that the transmission is
associated with lack of hygiene, exposure of animals and
the consumption of contaminated food or water. There is
considerable controversy about whether it is a commensal
organism or a true pathogen, so it has been proposed to
determine if there is a relationship between the
quantification of Blastocystis spp. (> 5 parasites / field
or <5 parasites / field) with the symptom that it produces,
with the possible transmission routes and if these criteria
has real clinical application. Therefore, a cross-sectional
study was being done, based on the review of medical
records, in which the variables that could be used in
logistic regression models to help respond to the variables
were selected using the Chi-square test that were proposed
in the objective. The results showed a significant
relationship with a greater number of 5 Blastocystis spp.
by field with the age of the patients, presenting chest
pain as a clinical symptom, having attended a medical
visit, presenting type 2 diabetes mellitus as an associated
comorbidity and the number of days of treatment. The rates
of infection of this parasite were higher in the areas of
Ejea de los Caballeros, Tarazona and Oliver in Zaragoza
capital. No significant differences were found between the
time distances in which the stool samples were taken
comparing with the quantification of the parasite by field.
This study, highlights the importance of an adequate
hygiene education, which protects the population, as far as
possible, the risks associated with the acquisition of
parasitic diseases, also the need for future studies to
determine the role played by Blastocytis spp. in digestive
pathology.",
