We evaluated antigen detection kits for human rotavirus with regard to their usefulness for diagnosing equine rotavirus infection. Limiting dilution analyses showed that of the seven kits investigated the Dipstick `Eiken' Rota (Dipstick) had the highest sensitivity to two serotypes of equine rotavirus. The Dipstick did not cross-react with several equine intestinal pathogens. An investigation u...

Using three serotypes (four strains) of cultivable porcine rotavirus as immunizing antigens, 10 neutralizing monoclonal antibodies were characterized. One VP4-specific monoclonal antibody directed against porcine rotavirus BEN-144 (serotype G4) neutralized human rotavirus strain ST-3 in addition to the homologous porcine virus. All nine VP7-specific monoclonal antibodies were highly specific fo...

Aim: The present study aimed to detect Human bocavirus (HBoV) in stool samples from young children below 5 years complaining of acute gastroenteritis (GE) addition detection rotavirus, norovirus, and astrovirus. Methods: included 90 with GE excluded bacterial pathogens. determination the presence HBoV was performed by nested polymerase chain reaction (PCR) beside astrovirus norovirus multiplex ...

A cultivable human rotavirus, Wa, was propagated in MA-104 cells and used as an antigen in immune adherence hemagglutination (IAHA) and complement fixation (CF) tests. IAHA antibody titers of sera from normal humans were found to be eightfold higher than CF antibody titers. The IAHA antibody determination with the Wa antigen is considered to be especially useful for the seroepidemiological stud...

Serotype G9 may be the fifth most common human rotavirus serotype, after serotypes G1 to G4. In three cross-sectional studies of childhood diarrhea, we have detected serotype G9 rotaviruses for the first time in Libya, Kenya, and Cuba. Serotype G9 constituted 27% of all rotaviruses identified, emphasizing the reemergence of serotype G9 and suggesting that future human rotavirus vaccines will ne...

A literature review was made to assess the epidemiology, public health importance, diagnostic and control methods of bovine rotavirus. Rotavirus is genus name under family Reoviridae which characterized by segmented genome. The emergence new serotypes virus related nature viral genome allows reassortment during mixed infections. rotavirus consists 11 double-stranded RNA gene segments encoding 6...

Human rotavirus strain Ro1845, which was isolated in 1985 from an Israeli child with diarrhea, has a hemagglutinin that is capable of agglutinating erythrocytes from guinea pigs, sheep, chickens, and humans (group O). Hemagglutination was inhibited after incubation with hyperimmune sera or in the presence of glycophorin, the erythrocyte receptor for animal rotaviruses. These results suggest tha...

abstract acute diarrhea with severe dehydration has been a major worldwide cause of death in children younger than 5 years of age. etiological studies of gastroenteritis have shown that rotavirus causes 40–50% of acute diarrhea among infants and children in both developing and developed nations. numerous epidemiologic studies in the us and the world health organization have documented the clini...

background: rotaviruses cause diarrhea in infants and young children worldwide. rotavirus outer capsid protein, vp7 is major neutralizing antigen that is important component of subunit vaccine to prevent rotavirus infection. many efforts have been done to produce recombinant vp7 that maintain native characteristics. we used baculovirus expression system to produce rotavirus vp7 protein and to s...

Nine human rotavirus strains from stools of infants with gastroenteritis were serially propagated in MA-104 cell cultures. All strains were identified as subgroup 2 rotaviruses by RNA gel electrophoresis, complement fixation, and enzyme-linked immunosorbent assay. The human rotavirus strains were propagated for 15 to 20 passages and then used for immunization of guinea pigs and rabbits. Animal ...
