Abstract

Background: MXPyV, like MWPyV, was identified in stool samples from children suffering diarrhea in Mexico. In this study, we used a home-made real time PCR to investigate the presence of this novel viruses in stool specimen collected from under-five-year-old children with gastroenteritis.

Methods: A total of 192 fecal specimens previously screened for RV, ADV, NoV, HPeV and SaV, were tested for MWPyV with Taqman real time PCR.

Results: The most detected virus was NoV GII (33.8%), followed by RV (21.3%), SaV (10.9%), HPeV (8%), NoV GI (6.7%) and Adv (1%). Real time PCR detected MWPyV in 1/192 (0.5%) patients.

Conclusions: We detected MWPyV in 0.5% of fecal specimens collected from pediatric patients suffering gastroenteritis which is smaller than the previously reported in literature (4.4% in Australia and 12% Mexico).
