filter paper solid-phase radioimmunoassay for human rotavirus surface immunoglobulins.a filter paper solid-phase radioimmunoassay has been developed. filter paper disks adsorbed a large amount of rotavirus and serum globulin and gave small mean variation of coating and low background binding. the rotavirus isolated from stools from infants with acute enteritis 1, 3, and 4 days after onset of symptoms was shown to be already covered with immunoglobulin g (igg), iga, and igm antibodies by this radioimmunoassay, by immunoelectrophoresis, and by immune electron microscopy. the immuno ...1977199613
human rotavirus enteritis induced in conventional piglets. intestinal structure and better understand the pathogenesis of infantile viral gastroenteritis, we studied na+ and cl- fluxes in vitro in short-circuited jejunal epithelium from 8-10-day-old piglets after infection with a standard dose of human rotavirus given via nasogastric tube. 11 infected piglets, all of whom became ill, were compared with 9 uninfected, healthy litter-mates. when killed 72 h after infection, intestinal villi were shorter and crypts deeper (p less than 0.025) in duodenum, upper jejunum, and mid-s ...1977199622
separation and infectivity of two particle types of human rotavirus.two morphological types of human rotavirus particles were separated in caesium chloride density gradients. the particles of higher density ('incomplete' particles without an outer capsid layer) banded at a density of 1-38 g/ml, while the less dense ('complete' particles with an outer as well as an inner capsid layer) banded at a density of 1-36 g/ml. some particles were found with an incomplete outer layer of capsomeres. the particle/infectivity ratio for tissue cultures of the fraction containi ...1977199702
antiviral activity of ribavirin in rotavirus gastroenteritis of mice.ribavirin was inactive against the rotavirus of murine gastroenteritis; this may be due to the presence of guanosine inhibitors in the gut.1977200170
enzyme-linked immunosorbent assay for diagnosis of rotavirus infections in enzyme-linked immunosorbent assay for the diagnosis of rotavirus infection in calves is described. the assay was more efficient for the detection of rotavirus antigens in calf feces than were electron microscopy and immunoelectroosmorphoresis.1977200635
distribution and titres of rotavirus antibodies in different age groups.three hundred and fifty-seven sera selected at random from hospital patients of all ages were examined for rotavirus antibodies using indirect immunofluorescence (fa) and complement fixation levels (cft). three hundred and fourteen of these were also tested for neutralizing antibodies to human rotavirus. sera from patients admitted with a diagnosis of acute gastroenteritis were excluded from this survey. fa antibodies were found in newborn infants but fell to undetectable titres at 3 months. the ...1977200676
observations on the morphology of two rotaviruses.the negative staining technique was used to study the morphology of two rotaviruses, the epizootic diarrizootic diarrhoea of infant mice (edim) and the simian virus sa ii. it is proposed that the inner capsid of the virion has icosahedral symmetry and consists of 180 morphological units arranged in an open lattice formation with the 12 spaces at the apices being surrounded by 5 capsomeres and the other 80 spaces each surrounded by six capsomeres. the outer capsid of the virion consists of a hone ...1977200716
cell culture propagation of porcine rotavirus (reovirus-like agent).two isolates of porcine rotavirus (reovirus-like agent) were isolated and passaged in primary procine kidney cell cultures. viral infectivity for cells was monitored by immunofluorescence because viral cytopathic effect was moderate. successful passage of virus in cell culture required that viral suspensions obtained from infected cell cultures be treated with pancreatin prior to inoculation onto cell monolayers. porcine rotavirus passage in cell culture also was accomplished, using trypsin trea ...1977201198

rotavirus infections of neonates.faecal specimens from 628 newborn babies in the nurseries of six metropolitan hospitals were examined by electron microscopy for rotaviruses. 304 babies (49%) were found to be excreting virus. all those infected were in five nurseries; viruses were not detected in specimens from the sixth nursery. two nurseries were studied for 9 mo and another for 11 mo and rotaviruses were found consistently in 40-50% of stools examined. there was no seasonal variation. none of the neonates under the age of on ...197773060
diarrhoea in pigs induced by rotavirus.electron microscope examination of the faeces of scouring pigs revealed virus particles which were morphologically indistinguishable from rotavirus (reo-like), a virus associated with diarrhoea in neonatal pigs (lecce, king & mock, 1976). this is the first record of the virus in the republic of south africa.1977206862
reovirus-like agent in acute epidemic gastroenteritis in japanese infants: fecal shedding and serologic response.the reovirus-like agent, sometimes referred to as duovirus or rotavirus, was visualized by electron microscopy in stool extracts from japanese infants and young children with acute epidemic gastroenteritis. the virus particles measured 70 nm in diameter and had double-shelled capsids. one hundred ten (89%) of 124 patients with the gastroenteritis had such virus particles in stools obtained during the acute phase. the virus particles were excreted in the stools usually during the first eight days ...1977402427
diagnosis of rotavirus infection by cell culture.rotaviruses were detected by electronmicroscopy in 35 of 84 specimens of faeces from infants with diarrhoea, and in 31 by fluorescent staining of tissue cultures infected with help of centrifugation. llc-mk2 cells were found to be the most sensitive, although primary and secondary human-embryo-kidney and primary calf-kidney cells could also be used. a micromodification of the tissue-culture method provides a relatively simple technique for the diagnosis of rotavirus infection, for the titration ...1977402472
complement-fixing antibody response to rotavirus infection.a human rotavirus complement-fixing (cf) antigen, prepared by purification of large volumes of fluid feces collected from children with winter diarrhea, was used to study the development and persistence of antibody in children with diarrhea and the prevalence of rotavirus antibody in melbourne. in children with diarrhea, antibody rises were detectable within 4 to 6 weeks of the onset of illness, and the titers usually remained elevated for the next 1 to 2 years. cf antibody did not develop in tw ...1977403196
stool viruses in babies in glasgow. i. hospital admissions with diarrhoea.stools from 183 babies under 2 years of age admitted to ruchill hospital with diarrhoea were examined by electron microscopy, virus culture, bacterial culture and light microscopy. as far as possible, several stools were examined from each patient and the results showed rotaviruses, astroviruses and other viruses in association with symptoms, as well as the expected bacterial pathogens. examination of several stools from the same patient also showed that in this age group the viral flora of the ...1977403233
rapid diagnosis of rotavirus infections: comparison of electron microscopy and immunoelectroosmophoresis for the detection of rotavirus in human infantile gastroenteritis.eighty-seven faecal samples from infants and children suffering from acute gastroenteritis were investigated for the presence of rotavirus by immunoelectroosmophoresis (ieop) and electron microscopy (em). sixty-one % of the samples contained rotavirus antigens when examined by ieop whereas only 50% were diagnosed as positive em. however, where it was possible to perform em within the same day that the sample was received it took 24 h to establish the diagnosis by ieop. the high sensitivity of th ...1977406356
aetiology of acute gastroenteritis in infancy and early childhood in southern india.the aetiology of acute gastroenteritis was studied in 50 infants and young children. bacterial pathogens were isolated in 33, enteropathogenic e. coli (epec), salmonella, and shigella being the commonest isolates. rotaviruses were detected in the stools of 13 of the cases. all children with gastroenteritis in whom rotavirus was detected were seen during the months july to december. in 30 children who served as controls, epec were isolated in 6, but rotavirus was detected in none. it is concluded ...1977406857
demonstration of size variation of rna segments between different isolates of calf rotavirus.polyacrylamide gel electrophosesis of rna extracted from wild rotavirus isolates and cell culture adapted virus revealed a significant variation in the molecular weight of individual rna segments. the major differences were observed between wild isolates on the one hand and the adapted strain on the other hand. the slight variations that were observed between different wild isolates were found regularly and appeared to be related to the origin of the samples.1977407327
[rotavirus and gastroenteritis in the newborn infant. initial observations].a simplified method for the diagnosis of rotavirus by electron microscopy is presented. the incidence of these viruses is observed in new-born infants and the relationship with acute gastroenteritis is recalled.1977408044
rotaviruses in venezuelan children with gastroenteritis.rotaviruses were identified by electron microscopy in 19 of 26 (73%) venezuelan children with gastroenteritis. noncultivable adenoviruses and small (29-30 nm), spherical viruses were also observed in a few cases. bacterial pathogens were isolated from five children (19%), all of whom were also carrying rotaviruses.1977842776
biochemical studies on a reovirus-like agent (rotovirus) from lambs.ten polypeptides were detected in double-capsid lamb rotavirus; four of these appeared to be associated with the outer capsid. lamb rotavirus rna, which consisted of 11 or 12 segments, differed from pig rotavirus rna in the electrophoretic mibility of one of the genome segments.1977850308
rotavirus infections in calves. ii. experimental infections with a dutch isolate.rotaviruses were observed electron microscopically in clarified faecal samples from calves with diarrhoea. several herds with a history of scouring among neonatal calves were shown to be infected with rotaviruses. a bacteria-free faecal filtrate from a rotavirus positive sample administered orally induced diarrhoea in one out of two colostrum-deprived calves. both calves excreted rotaviruses in their faeces and serum antibody responses were demonstrated by complement-fixation and indirect immuno ...1977857337
propagation of the rotavirus of neonatal calf diarrhea in fetal intestinal cell cultures.bovine fetal intestinal cells were successfully propagated in monolayer cultures for up to 21 passages. infection of these cells with the rotavirus of neonatal calf diarrhea resulted in a cytopathic effect that was more obvious than in infected bovine fetal kidney cells.1977861843
solid-phase radioimmunoassay for the detection of rotavirus.a solid-phase radioimmunoassay method has been developed for the detection of rotavirus in the form of a purified antigen and in stool. the parameters of the radioimmunoassay were examined and optimized to give high sensitivity and same-day results. compared with electron microscopy, the assay is up to 10 times as sensitive for detection of the virus in stool and up to 128 times as sensitive for detection of a purified virus antigen. in a field study on stool specimens it was at least as effici ...1977863510

rotavirus infection in lambs: studies on passive protection.gnotobiotic lambs were protected against rotavirus infection by the presence in the gut at the time of infection of colostrum or serum containing antibodies to rotavirus. this protection was observed even when passively-acquired antibody was not present in the serum of the infected lamb. infection under these conditions may have conferred immunity to subsequent challenge.1976999520
winter diarrhoea and rotaviruses in the winter fewer bacterial pathogens are isolated from patients with gastro-enteritis than in the summer. the incidence of rotavirus infection is, however, at its greatest during the winter months and the virus is rarely found in cases of gastro-enteritis which occur during the warm season. the clinical pattern in winter diarrhoea is characteristically severe and acute but there has been no mortality or cross-infection.19761006454
[rotavirus infection in calves (author's transl)].several laboratory workers have demonstrated a viral agent, suspected of playing an important role in the aetiology of calf diarrhoea during the first weeks of life. based on its morphology this agent was designated a reo-like virus. later the name rotavirus was introduced. rotaviruses were proved experimentally to induce diarrhoea in calves. usually the course of the disease after similar experimental infection is mild, but could become worse with secondary bacterial infections. the available i ...19761013979
[in vitro culture of a rotavirus associated with neonatal calf diarrhea].about fifty diarrheic fecal samples in which the calf rotavirus was present in variable quantities were passed in tissue cultures and the ability of the virus to replicate was analysed under different experimental conditions by means of an indirect immunoflourescent test. several cell species were shown to be susceptible to the virus but the best results were obtained in primary or secondary cultures of embryonic calf kidney cells in presence of maintainance medium containing 2 to 4 p. 100 foeta ...19761028381
reovirus-like agent (rotavirus) from lambs.rotavirus particles were demonstrated by electron microscopy in the feces of lambs with diarrhea. rotavirus antigen was synthesized in cell cultures infected with filtrates of the diarrheic feces, but the virus was not adapted to grow serially in cell cultures. an antigenic relationship between rotaviruses from lambs, pigs, and calves was demonstrated by immunofluorescence. colostrum-deprived lambs were infected with the lamb rotavirus, and the virus was passaged in lambs. viral replication occu ...1976793991
characteristics of the genome of human infantile enteritis virus (rotavirus).thermal denaturation studies and polyacrylamide gel electrophoretic analysis have shown that the genome of human infantile enteritis virus (human rotavirus) consists of approximately 11 double-stranded segments. differences in the molecular weights of some of the corresponding genome segments are apparent between different isolates of the virus.1976820876

reovirus-like agent (rotavirus) associated with neonatal calf gastroenteritis in france.a reo-like virus (calf rotavirus) was shown to be associated with cases of neonatal calf diarrhea in france. the virus could be detected in more than 50 p. 100 of diarrheic fecal samples, while it was practically absent in control samples originating from healthy calves that had never had diarrhea. the results obtained by electron microscopy and immunofluorescent studies indicate that the virus is closely related or identical to the agent isolated originally in the united states.1976185934
implications of recent virological researches.rotaviruses (duoviruses) can be found in more than half the cases of acute diarrhoea in children up to the age of six or seven. about that age almost everyone has antibodies to them. second infections occur and may not be as rare as laboratory findings so far suggest. very young infants sometimes get subclinical disease-the effect of maternal antibody transmitted across the placenta? very similar viruses, all possessing a common antigen detectable by immunofluorescence, are known to infect and/o ...1976186237
pathogenic rotaviruses isolated from pigs and calves.rotavirus is commonly isolated from diarrhoeic calves and pigs. bacterium-free faecal filtrates containing rotavirus from five different outbreaks of disease in calves all caused diarrhoea and clinical illness in gnotobiotic calves and five different isolates from pigs were inoculated into gnotobiotic pigs with similar results. the author was unsuccessful in finding an avirulent strain although one of the calf isolates was from a non-diarrhoeic calf. the laboratory strain of calf virus retained ...1976186238
recent advances in the aetiology of viral gastroenteritis.studies with the human reovirus-like (hrvl) agnet, also designated rotavirus and duovirus, have revealed that it is a major aetiological agent of diarrhoea of infants and young children in many parts of the world. in a study of patients admitted with a diarrhoeal illness to the children's hospital of the district of columbia in the united states from january 1974 to june 1975, it was found that half of the patients studied by both virus shedding (by electron microscopy) and serological (compleme ...1976186239
