Entre agosto y diciembre dese recolectaron muestras de heces provenientes de neonatos sanos. Estos ensayos identificaron como positivas a rotavirus y calicivirus a un humxnos 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 humano 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 a la familia Reoviridae.

P2, ausente en las cepas de rotavirus que usualmente circulan en infantes [6].

Mas recientemente, Flores y col. Como controles positivos se incluyeron muestras fecales de infantes previamente probadas positivas para rotavirus. Electroforesis en geles de poliacrilamida. Las muestras que resultaron positivas para calicivirus fueron analizadas en dos oportunidades por RT-PCR, en un caso siguiendo el protocolo descrito por Jiang y col.

Los cebadores descritos por Jiang y col. El promedio de peso al nacer de los neonatos incluidos en este estudio fue de 3. 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.
