| structural analysis of electrophoretic variation in the genome profiles of rotavirus field isolates. | detailed structural studies were undertaken on five isolates of bovine rotavirus which showed variability in the migration patterns of their genome segments on electrophoresis in polyacrylamide gels. the individual genome segments of each isolate were characterized by partial digestion of terminally radiolabeled rna with a base-specific nuclease. this analysis showed that whereas mobility variations were always associated with detectable changes in nucleotide sequence, sequence changes at least ... | 1982 | 6282750 |
| complement-fixation test for rotavirus detection: comparison and analysis of different methods to reduce anti-complementary activity of some specimens. | the complement-fixation test may be used to detect rotaviral antigens directly in clinical specimens. however, a certain number of specimens tested for human rotaviruses by the complement-fixation test show an anti-complementary activity. by comparing eight techniques we analysed this anti-complementary activity and identified the best method for its reduction. pretreatment of clarified supernatant of stool suspensions by some methods resulted in a reduction of anti-complementary activity, witho ... | 1982 | 6282917 |
| epidemiology of diarrhea due to rotavirus on an indian reservation: risk factors in the home environment. | analysis of outpatient visits for diarrheal disease at the san carlos apache reservation, arizona, during 1977-1979 revealed a sharp increase in cases of infantile gastroenteritis of unknown etiology in october and november of each year. during the 1980 autumn diarrhea season, 19 patients and 12 control subjects were selected from among outpatients under two years of age and were interviewed and studied for bacterial and viral enteric pathogens. eleven (58%) of 19 patients and two (17%) of 12 co ... | 1982 | 6282985 |

| incidence of rotavirus in artificially reared pigs and some effects of diarrhoea on the physiology and histology of the gastrointestinal tract. | pigs reared on a milk substitute from two days old often developed diarrhoea, but suckled littermates remained healthy. only in a few pigs was diarrhoea associated with the presence of rotavirus. rotavirus was also present in some healthy pigs, and was associated with a reduction in villus length. pigs with diarrhoea usually had an increased amount of digesta in the stomach and a reduction in lactase activity in the small intestine but villus length was unchanged. there was no evidence of lactos ... | 1982 | 6283612 |
| diarrhoea in dairy calves reduced by feeding colostrum from cows vaccinated with rotavirus. | forty-two dairy calves remained with their dams for two days after birth, and then were removed to a calf rearing shed. calves were allocated to three groups for the next 14 days, and received twice daily either whole milk, whole milk with a 10 per cent supplement of pooled normal bovine colostrum or whole milk with 10 per cent supplement of colostrum from cows vaccinated with rotavirus. a natural outbreak of diarrhoea occurred, affecting 28 of the 42 calves. feeding immune colostrum delayed the ... | 1982 | 6283613 |
| influence of humidity on rotavirus prevalence among nigerian infants and young children with gastroenteritis. | rotaviruses were detected by counterimmunoelectro-osmophoresis in the feces of 16 (13.8%) of 116 infants and young children with gastroenteritis during a 5-month period (september 1979 through january 1980) in ife, nigeria. the rate of rotavirus detection varied inversely with relative humidity and was highest in december (38.5% positive) when the humidity was lower. there was not such a distinct relationship with temperature or vapor pressure; and although the rate of rotavirus detection was hi ... | 1982 | 6279690 |
| porcine pararotavirus: detection, differentiation from rotavirus, and pathogenesis in gnotobiotic pigs. | some characteristics of a newly recognized porcine enteric virus are described. tentatively, the virus was referred to as porcine pararotavirus (parv) because it resembled rotaviruses in respect to size, morphology, and tropism for villous enterocytes of the small intestine. however, it was antigenically distinct from porcine, human, and bovine rotaviruses and reoviruses 1, 2, and 3, and the electrophoretic migration pattern of parv double-stranded rna was distinct from the electrophoretic migra ... | 1982 | 6279693 |
| acquisition of serum antibody to norwalk virus and rotavirus and relation to diarrhea in a longitudinal study of young children in rural bangladesh. | serum antibodies to norwalk virus and to rotavirus were measured during longitudinal studies of infectious diseases and nutrition in rural bangladesh. initially, the prevalence of antibody to norwalk virus was 7% in children younger than six months and increased to 80% in children two to five years of age. the incidence of titer increases was highest in one- and two-year-olds and in children who had low or undetectable levels of antibody. some norwalk virus infections appeared to result in diarr ... | 1982 | 6279734 |

| [immunofluorescence reaction for rotavirus analysis in fecal specimens]. | testing for rotavirus detection in faeces from infants with acute diarrhea can be carried out, with high sensitivity, by immunofluorescence on rhesus monkey kidney cell lines (ma-104). preincubation of viral inoculum with trypsin enhances further the sensitivity. in the present study we tried to assess the optimal conditions for detection of viral antigens, by analyzing the expression of virus-specific proteins at different times of infection and the effects of trypsin presence during virus adso ... | 1983 | 6330786 |

| influence of temperature and relative humidity on human rotavirus infection in japan. | a climatologic analysis of human rotavirus infection in inpatients with acute diarrhea was conducted over a seven-year period. the infection frequency appeared to be related to temperature, but not to relative humidity. human rotavirus infection was found to appear abruptly when the mean temperature of any 10-day period became less than 5 c (november or december), reached a peak when it was less than 0 c (january and february), and waned when it became greater than 20 c (june and july) in the ci ... | 1983 | 6822748 |

| the microbiology of childhood gastroenteritis: aeromonas species and other infective agents. | a prospective, 12-month study of 975 non-aboriginal children with diarrhea and age- and sex-matched children without diarrhea, in perth, western australia, was designed to investigate the significance of enterotoxigenic aeromonas species as a cause of diarrhea. enterotoxigenic aeromonas species were found in the fecal specimens of 10.8% of the patients with diarrhea but in only 0.7% of those without diarrhea. most aeromonas species were isolated during the summer. other important bacterial patho ... | 1983 | 6886488 |
| investigation of acute gastroenteritis in general practice--relevance of newer laboratory methods. | over a nine-month period, all patients suffering from acute gastroenteritis, with diarrhoea as an essential component, who presented to a group practice in southern england were investigated using conventional laboratory methods, and also newer techniques of electron microscopy and search for species of campylobacter. rotavirus and campylobacter were the two most commonly encountered pathogens. | 1983 | 6887127 |

| viral gastroenteritis and laboratory detection of rotavirus. | two major viruses have been clearly associated with gastroenteritis: the norwalk agent and the rotavirus. the former is associated with epidemic outbreaks in adults or schoolchildren, while the latter causes endemic illness in young children during winter. neither can be grown in routine cell cultures. both of these viruses, and others, can be detected in patients' stools by electron microscopy. enzyme linked immunosorbent assay (elisa) kits are commercially available for detection of rotavirus ... | 1983 | 6326572 |
