Serological evidence of rotavirus infection in guinea pig colony
Castro,L. de; Araújo,H. P. de; Fialho,A. M.; Gouvea,V. S.; Pereira,H. G.Antibodies reacting with simian rotavirus SAII were detected by enzyme immunoassay (EIA) and Western blot assay (WBA) in sera from guinea pigs bred for experimental use at the Fundação Oswaldo Cruz, Rio de Janeiro, Brazil. The proportion of antibody-positive animals and the antibody titres rose sharply in 1985, were maintained at a high levels in 1986 and declined in 1987. There were no obvious signs of disease...
A comparison of simian rotavirus SA11 preparations maintained in different labo...
Pereira,H. G.; Gouvea,Vera S.; Fialho,A. M.Preparations of simian SA11 maintained in different laboratories were compared with each other by polyacrylamide gel electrophoresis of genomic RNA. Differences in the migration of genome segments 4,5 and 7 allowed the classification of eight virus preparations into four electrophoretic types.
An atypical rotavirus detected in a child with gastroenteritis in Rio de Janeir...
Pereira,H. G.; Leite,J. P. G.; Azeredto,R. S.; Farias,Vivian de; Sutmoller,FritsParticles morphologically identical to rotaviruses were found in the faeces of a nine week-old child with gastroenteritis. Analysis of the viral RNA genome by polyacrylamine gel electrophoresis revealed 10 bands (probably 11 segments) some of wich differed in migration rate from those of the great majority of rotaviruses infecting man and other animal hosts. The virus was not detected by a highly sensitive enzy...

Pereira,H. G.; Azeredto,R. S.; Sutmoller,F.; Leite,J. P.; Farias,V. de; Barth,O. M.; Vidal,M. N. P.Detection of rotavirus RNA by polyacrylamide gel electrophoresis (PAGE) proved to be a highly sensitive and rapid diagnostic test. A comparison of this assay with immuno-electron microscopy (IEM) and enzyme immunoassay (EIA) in 245 faeces from children with gastroenteritis revealed complete agreement between the three assays in 238 (97.14%) samples. Among 75 samples positive in at least one of the three assays,...
