MW Polyomavirus in diarrheal Italian infants

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