Estos ensayos identificaron como positivas a rotavirus y calicivirus a virhs total de 14 y 58 muestras, respectivamente. Study of rotavirus and calicivirus infections in neonates from the. The purpose of this work was to study rotavirus infection in neonates at the Maternity Hospital and compare the new data with those previously obtained.

We also studied calicivirus presence in said population. Between August and Decemberfeces samples were collected from healthy neonates. These assays identified a total of 14 and 58 samples as rotavirus and calicivirus positive respectively. These results suggest the non-circulation of both rotavirus and calicivirus within the Maternity Hospital.

It is possible that the interruption of rotavirus transmission within this Institution could be due to changes in the management of the mother-child unit promoted by WHO and UNICEF, and introduced at the Maternity Hospital since Recibido 14 de octubre de ; aceptado 8 de febrero de Los rotavirus pertenecen diwrrea la familia Reoviridae.

Treinta y siete de las 58 muestras sospechosas fueron analizadas por RT-PCR utilizando dos juegos de cebadores con especificidades distintas, sin embargo, ninguna de ellas pudo ser confirmada como positiva.
