synthesis of coreless, probably defective virus particles in cell cultures infected with rotaviruses.	pk-15 cells infected with pig and lamb rotavirus strains which were not adapted to serial growth in cell cultures were examined by electron microscopy. a major difference between virus morphogenesis in the initial passage in pk-15 cells and in intestinal epithelial cells was the generation of large numbers of coreless virus particles in pk-15 cells. the numbers of coreless particles increased with increasing multiplicity of infection. infectious virus was synthesized in pk-15 cells, but a variab ...	1978	215104
isolation of rotavirus from foals with diarrhoea.	a rotavirus, morphologically similar to other known rotaviruses, was demonstrated in the faeces of 5 foals with diarrhoea on two properties. four of these 5 samples produced specific intracytoplasmic fluorescence in cell culture when reacted with calf rotavirus antiserum conjugate. sixteen affected foals from both properties were depressed, did not suckle and became recumbent. most had a watery diarrhoea which lasted for 3 days and resulted in some dehydration and loss of body condition. sick fo ...	1978	215112
physicochemical properties of nebraska calf diarrhea virus hemagglutinin.	highly purified nebraska calf diarrhea virus (ncdv) was prepared by cesium chloride density gradient centrifugation. the effect of temperature, ph, different concentrations of formaldehyde, chloroform, ether, ethyl alcohol, and methyl alcohol on ncdv hemagglutinin and virus morphology was studied. ncdv hemagglutinin was inactivated by temperature, ph 2.0, chloroform, ethyl alcohol, and methyl alcohol.	1978	33758
neonatal calf diarrhea caused by a virus that induces villous epithelial cell syncytia.	intestinal lesions caused by a virus serologically unrelated to the calf diarrheal rotavirus or coronavirus were studied in gnotobiotic calves. the virion purified from feces from infected calves was a fringed particle with a diameter of about 100 nm. the incubation period from time of inoculation per orum to onset of diarrhea in calves was as short as 8 hours. the viral infection in bacteria-free calves or calves not contaminated with pathogenic bacteria caused severe illness for only 24 hours. ...	1978	98080
pattern of shedding of two noncultivable viruses in stools of newborn babies.	noncultivable viruses have been associated with diarrhea affecting newborn babies in obstetric hospital nurseries. persisting infection in a special care nursery in melbourne, australia, permitted a study of the pattern of excretion of these viruses. ten babies admitted to the nursery within 2 hr of birth were randomly selected for prospective study. feces were collected daily for 14 days and were examined by electron microscopy. all ten babies excreted detectable amounts of duovirus (rotavirus, ...	1978	98612

search by immunofluorescence for antigens of rotavirus, pseudomonas maltophilia, and mycobacterium kansasii in crohn's disease.	crohn's-disease tissue was tested by indirect immunofluorescence for antigens of rotavirus, pseudomonas maltophilia, and mycobacterium kansasii. no reactions were obtained with anti-serum to p. maltophilia and m. kansasii, and a granular fluorescence seen with rotavirus antibody was probably non-specific.	1978	80631
classification of rotaviruses: report from the world health organization/food and agriculture organization comparative virology program.	the reoviridae working team was established under the world health organization/food and agriculture organization comparative virology program in 1975. the generic name rotavirus has been adopted for the reovirus-like agents associated with diarrhea in man and animals, and the nebraska calf diarrheal virus strain of bovine rotavirus has been selected as a candidate reference virus. stocks of this virus and of gnotobiotic calf antiserum have been prepared. antigenic differences among rotaviruses ...	1978	81198
location of type-specific antigens in calf rotaviruses.	rotavirus antisera with and without neutralizing activity to calf rotavirus were compared for their ability to agglutinate calf rotavirus particles with and without an outer capsid layer. particles without the outer capsid layer were agglutinated by antisera with immunofluorescent antibody activity and by antisera with immunofluorescent antibody and neutralizing activity. particles with the outer capsid layer were agglutinated only by antisera with neutralizing activity. the neutralization test ...	1978	84819
hemagglutination and hemagglutination-inhibition studies with a strain of nebraska calf diarrhea virus (bovine rotavirus).	a hemagglutinin has been prepared from nebraska calf diarrhea virus (ncdv) propagated in bs-c-1 cell line. after cesium chloride centrifugation, the hemagglutinin of the bovine rotavirus was found to be associated with intact virions (density 1.355 g/ml) but not with virions lacking an outer capsid layer (density 1.375 g/ml). in hemagglutination-inhibition (hai) tests, the hemagglutinin reacted specifically with ncdv serum, and hai seroconversions were detected in some sera tested. cross-reactio ...	1978	201585
[epidemiological aspects of gastroenteritis dut to rotavirus].	during december 1976 to january-march 1977, 13/53 children less than 5 years of age were admitted with acute enteritis caused by rotaviruses to the hospital del niño, dif. there is already convincing evidence that this new virus will prove to be the most important etiological agent of sporadic acute enteritis in young children.	1978	202294
a simple method for concentration of enteroviruses and rotaviruses from cell culture harvests using membrane filters.	organic compounds in cell culture harvests known as membrane-coating components (mcc) prevent virus adsorption to membrane filters. blending cell culture harvests with fluorocarbon removed the mcc and permitted adsorption of virus in acidified harvests to epoxy-fiberglass filters. subsequent elution with high ph buffer resulted in recovery of greater than 90% of the virus with concentrations of up to 100-fold.	1978	202572
the role of breast-feeding in the prevention of rotavirus infection.	breast-fed infants are less susceptible to gastroenteritis than bottle-fed infants. antibodies against rotavirus, the major pathogen of infantile gastroenteritis, were sought in human sera, colostrum and milk specimens by immunofluorescence. an experimental murine-rotavirus model was established by infecting the second litters of dams 4 weeks after infecting their first litters. antibodies were absent from human and murine colostrum and milk specimens despite being present in virtually all sera, ...	1978	202710
rearing regimen producing piglet diarrhea (rotavirus) and its relevance to acute infantile diarrhea.	piglets were weaned when 1 day old and thus were denied further access to the antibodies supplied by their dam's milk. they were placed in a nursery in which contamination by the ubiquitous rotavirus steadily increased with continuous use causing a progressive increase in the incidence of vomiting, diarrhea, and death among the piglets. a similar syndrome involving an antigenically related rotavirus and analogous management practices occurs in human infants.	1978	203032
[existence of 2 types of rotavirus associated with acute gastroenteritis in children].	rotaviruses found in the stools of different infants, hospitalized in the hospital del niño del dif, may be grouped into at least two types according to their rna composition. the viral rna composition was analyzed by electrophoresis in agarose gels. the different types can be distinguished by the mobility of the second larger of the 11 segments that make up the viral rna.	1978	203294
[diagnosis of rotavirus using viral rna electrophoresis].	rotavirus has emerged as a major agent of acute enteritis of infants. a rapid and simple technique has been developed for its detection, based on the visualization of the viral rna electrophoretic pattern. this technique takes advantage of the large amount of rotavirus present in the stools and the high sensitivity for detection of rna obtained with ethidium bromide.	1978	203295

fatal rotavirus gastroenteritis: an analysis of 21 cases.	during the period of may 1972 to march 1977, twenty-one fatal cases of rotavirus acute gastroenteritis were recorded in the city of toronto. the mean age of these subjects was approximately 1 year. boys outnumbered girls by 12 to 9. death occurred within three days of onset of symptoms in all cases. sixteen of the subjects were profoundly dehydrated and had sodium levels (serum or vitreous humor) in excess of 150 meq/liter. in 11 subjects, sodium values were greater than 160 meq/liter. although ...	1978	206132
lapine rotavirus: preliminary studies on epizoology and transmission.	antibody to rotavirus was found in sera of domestic rabbits, wild cottontail rabbits and snowshoe hares. eight out of 187 stools from a rabbitry contained rotavirus, though no clinical symptoms were apparent. the virus extracted from one such stool infected a five week old seronegative rabbit and led to distention and congestion of the colon, excretion of virus in the stool and a serological response to virus. human and simian rotaviruses did not replicate in the rabbits.	1978	206325
characteristics of neonatal calf diarrhea virus ribonucleic acid.	the nucleic acids of neonatal calf diarrhea virus were characterized by isopycnic centrifugation in cs2so4, electron microscopy, ultraviolet absorbance temperature profiles and polyacrylamide gel electrophoresis. these studies indicated that the neonatal calf diarrhea virus genome consists of 11 segments of double stranded rna with a total molecular weight of 10.75 million daltons.	1978	206326
diarrhea in newborn cynomologus monkeys infected with human rotavirus.	of six newborn cynomolgus monkeys (macaca fascicularis) naturally delivered and normally nursed five developed diarrhea after oral administration of human rotavirus. virus excretion was observed in the stool of four animals. this virus was transmitted to four out of six other monkeys causing diarrhea in only one animal.	1978	206515
hemagglutination by simian rotavirus.	a simian rotavirus (sa-11) was shown to hemagglutinate human group "o" and guinea pig erythrocytes. the hemagglutinin appeared to be associated with the outer capsid of the sa-11 virus and was inhibited by specific hyperimmune anti-sa-11 guinea pig serum.	1978	206575
morphogenesis of porcine rotavirus in porcine kidney cell cultures and intestinal epithelial cells.	the morphogenesis of porcine rotavirus was similar in vitro in porcine kidney (pk) cell cultures and in vivo in porcine epithelial cells as examined by electron microscopy. infected cells contained cytoplasmic, non-membrane-bound viroplasm and accumulations of virus particles within cisternae of the rough endoplasmic reticulum (rer). three types of virus particles were noted: double-shelled or complete particles which averaged 77 nm in diam.; single-shelled or naked particles which ranged from 5 ...	1978	206653
