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.	1976	999520
winter diarrhoea and rotaviruses in rhodesia.	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.	1976	1006454
[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 ...	1976	1013979
[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 ...	1976	1028381

rotaviruses and acute gastroenteritis of infants and children.	by means of electron microscopy and ultracentrifugation techniques rotavirus-like particles have been found in 84 of 269 specimens of faeces collected from infants and young children admitted to the royal alexandra hospital for children, camperdown, n.s.w. during the usual winter outbreak of infantile gastroenteritis. morphologically intact viruses were also found in faecal specimens stored at -20 degrees c for up to nine years. rotaviruses were found in specimens collected from five newborn inf ...	1976	1263949
an epidemic of diarrhoea in human neonates involving a reovirus-like agent and 'enteropathogenic' serotypes of escherichia coli.	during december 1974, an epidemic of diarrhoea occurred in the royal children's hospital, melbourne, in a ward caring for neonates with acute or chronic medical and surgical problems. electron microscopy of diarrhoeal faeces revealed a reovirus-like particle ('duovirus' or 'rotavirus') known to cause acute enteritis in older children. this virus is considered to have been primarily involved in the aetiology of the epidemic. in addition, three 'enteropathogenic' serotypes of escherichia coli were ...	1976	175099
a reovirus-like agent (rotavirus) in gastroenteritis of children. virus detection and serological studies.	a reovirus-like agent (rotavirus) was detected in 26 children (44%) when fecal specimens from 59 children with acute gastroenteritis were examined by electron microscopy. no rotavirus was detected in the feces of 49 children with other diseases. sera from the acute and the convalescent phase from 40 children with acute gastroenteritis and from 18 other patients were examined for antibodies against a bovine rotavirus by an indirect fluorescent antibody test. 26 of the patients with gastroenteriti ...	1976	178049
characterization of two particle types of calf rotavirus.	two distinct types of rotavirus particle were isolated in caesium chloride density gradients. the higher density particle banded at 1-38 g/ml and measured 55 +/- 0-4 nm in diameter while the less dense particle banded at 1-36 g/ml, measured 66 +/- 0-4 nm in diameter and appeared to possess an extra outer capsid layer. some forms intermediate between the two types were seen. since the two particles had a similar but not identical morphology and polypeptide composition, they were considered to be ...	1976	180243
the isolation of reovirus-like agents (rota-viruses) from acute gastroenteritis of piglets.	isolations of reovirus-like agents (rotaviruses) were made from nine of 23 outbreaks of piglet diarrhoea on different farms and from both weaned and unweaned piglets. the viruses were shown to be morphologically and anti-genically similar to the rotaviruses of children and calves. gnotobiotig piglets given intranasal inoculations of five different isolates developed acute gastroenteritis, and the virus was re-isolated from the faeces or intestinal contents. the piglet virus was not adapted to re ...	1976	180294

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.	1976	185934
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 ...	1976	186237
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 ...	1976	186238
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 ...	1976	186239
