Reoviruslike particles were visualized by electron microscopy in stool filtrates prepared from stools of infants and young children with severe acute gastroenteritis. Patients who had such particles in their stools and whose paired acute and convalescent serums were tested developed an antibody response to the reoviruslike agent, which was measured by immune electron microscopy and by complement fixation. The reoviruslike agent was antigenically related to the epizootic diarrhea of infant mice virus and the Nebraska calf diarrhea virus.
The Challenge Awards are designed to provide a unique perspective to students gifted in the arts and humanities from which to understand scientific endeavor by giving students an opportunity to participate in an ongoing research project. In the graduate program, seven students who had participated in previous Challenge Awards programs were selected to help develop the tools for Earth observations for the astronauts on the Space Radar Laboratory (SRL) missions. The goal of the Challenge Awards program was to prepare a training manual for the astronauts on the SRL missions. This paper describes the observations to be made by the astronauts on the SRL missions. The emphasis is on the dynamic seasonal features of the Earth's surface and atmosphere which justify the need for more than one flight of the SRL. Complete notebooks of the sites, global seasonal patterns, examples of radar and the Measurement of Air Pollution from Satellites data, and shuttle photographs have been given to each of the SRL crews.
During October, November and December, 1959, para-influenza 2, or croup-associated (CA), virus was recovered from 7 of 28 patients with croup. Three additional patients were infected with this agent, as indicated by serologic tests. The incidence of virus recovery from patients with croup was many times greater than from comparable control infants and children, regardless of the attribute compared. These findings constitute the first evidence from controlled epidemiologic studies that para-influenza 2 virus has an etiologic relationship to the croup syndrome. They also indicate the variable prevalence of para-influenza 2 virus, which differs from the almost constant presence of para-influenza 3 virus and para-influenza 1 virus in the pediatric population under study.
In a study of children who were hospitalized or were attending a hospital outpatient department: 1) One of seven different Group A Coxsackie viruses was isolated from 9.1 per cent of 620 children. 2) The virus was recovered from 9.5 per cent in the outpatient department, 6.7 per cent in patients hospitalized less than 5 days and 10.3 per cent in patients hospitalized for 5 days or more. 3) The strains of virus were essentially those which have been found in patients with herpangina. 4) In 10 instances, the virus was isolated after the patient had been in the hospital for 10 days and had had at least 2 negative tests previously. 5) If patients with herpangina are excluded, no significant correlation between type of illness and virus isolation can be drawn from this study. These data are considered further to reemphasize the fact that many Group A Coxsackie viruses are prevalent during the summer, and to support the hypothesis that some patients acquire these viruses while they are in the hospital at a rate similar to that observed in the general community from which the patients come.
