Isolation of group A swine rotaviruses displaying atypical electropherotypes.
Swine rotaviruses displaying distinctive electropherotypes were isolated from the feces of diarrheic piglets in two swine herds in the province of Buenos Aires, Argentina. In one case all samples isolated showed abnormal electropherotypes. All samples were classified as group A reactive when assayed by an enzyme-linked immunosorbent assay. Three samples from this herd were adapted to grow in ti...
متن کاملElectropherotypes and subgroups of group A rotaviruses circulating among diarrhoeic children in Kano, Nigeria.
BACKGROUND It is estimated that about 600,000 children die annually as a result of severe dehydrating diarrhea caused by rotaviruses. The virus is a double stranded RNA (dsRNA) virus with 11 segments. Group A rotaviruses show a characteristic 4-2-3-2 pattern following electrophoresis. The VP6 subgroups, I and II exist. This work was carried out to study the prevalence of rotavirus infection amo...
متن کاملIsolation, immunochemical demonstration of field strains of porcine group A rotaviruses and electrophoretic analysis of RNA segments of group A and C rotaviruses
Rotaviruses are major cause of acute diarrhea in animals and humans which can result in huge economic losses in farm animals including pigs. We collected 195 samples of feces of diarrhoeic animals. Rotavirus was demonstrated by electron microscopy using the method of negative staining in 27 samples and by ELISA test using monoclonal antibodies to the group antigen VP6 in 44 samples. Nine sample...
متن کاملHuman group C rotaviruses identified in Kenya.
BACKGROUND Rotavirus is associated with acute infantile gastro-enteritis in infants and young children worldwide. Rotavirus is associated with the high cases of morbidity and mortality and it is estimated that up to 650,000 deaths in young children occur annually in the less developed countries. Approximately a quarter of these deaths occur in African children yet minimal data exist on the circ...
متن کاملSequence analysis of the guanylyltransferase (VP3) of group A rotaviruses.
The RNA segment encoding the guanylyltransferase (VP3) from 12 group A rotavirus isolates has been sequenced following RT-PCR and molecular cloning of the full-length amplicons produced. Alignment of the derived amino acid sequences including those of the four VP3 sequences available from GenBank revealed two levels of sequence divergence. Virus isolates from humans showed greater than 94% sequ...
