Serological studies with reovirus-like enteritis agent.

The age distribution of antibody to the human reovirus-like enteritis agent, and to the antigenically related Nebraska calf diarrhea virus (NCDV) was studied in serum specimens obtained from 592 children hospitalized in Boston. Sera were examined for complement-fixation (CF) antibody to the human agent, and for CF and indirect immunofluorescence-staining antibodies to NCDV. The curve of antibod...

Detection of neonatal calf diarrhea virus, infant reovirus-like diarrhea virus, and a coronavirus using the fluorescent virus precipitin test.

Thirty-four calf and five infant fecal specimens were tested for the neonatal calf diarrhea virus (NCDV) and for the reovirus-like infantile diarrhea agent; respectively. The procedures used were the fluorescent virus precipitin test and immune electron microscopy. Fourteen of the calf stools contained detectable NCDV, and four of the five infant stools contained the reovirus-like human agent. ...

Distinct reovirus-like agents associated with acute infantile gastroenteritis.

Human reovirus-like particles were found by electron microscopy in the stools of 25% of 71 infants and young children hospitalized with acute gastroenteritis in Mexico between December 1976 and April 1977. The virus was also identified by the electrophoresis patterns of its ribonucleic acid upon disruption of partially purified particles. This technique is as reliable as electron microscopy but...

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.

Mucosal disease-like syndrome in a calf persistently infected by Hobi-like pestivirus.

A calf persistently infected with Hobi-like pestivirus displayed severe clinical signs and subsequently died. Gross lesions and histopathological changes were suggestive of hemorrhagic and necrotic inflammation involving several tissues. A Hobi-like pestivirus pair was isolated from the dead calf, i.e., cytopathogenic (CP) and noncytopathogenic (NCP) strains strictly related to each other and t...
