Sequence analysis of VP4 and VP7 genes of nontypeable strains identifies a new pair of outer capsid proteins representing novel P and G genotypes in bovine rotaviruses.
During a limited epidemiological study, the serotype specificities of several isolates of bovine rotavirus, exhibiting identical electropherotypes, from a single cattle farm near Bangalore, India, could not be determined using a panel of serotyping monoclonal antibodies (MAbs) specific for G serotypes 1-6 and 10. To determine the genotypes of these isolates, the nucleotide sequences of the gene...
متن کاملDiversity of rotavirus VP7 and VP4 genotypes in Northwestern Nigeria.
BACKGROUND Nigeria has recently been ranked third among the 10 countries with the greatest number of rotavirus disease-associated deaths per year. Estimates attribute up to 33,000 deaths annually to rotavirus disease in Nigerian children <5 years old. Although the introduction of the new oral, live attenuated rotavirus vaccines may not occur for another 4-6 years in developing countries, backgr...
متن کاملTwo-way cross-neutralization mediated by a shared P (VP4) serotype between bovine rotavirus strains with distinct G (VP7) serotypes.
Among bovine rotavirus strains, there are three G serotypes (G6, G8, and G10) and three P (VP4) serotypes (PB1, PB2, and PB3, which are defined on the basis of strains NCDV, UK, and B223, respectively). Plaque reduction neutralization assays with hyperimmune antisera disclosed two-way antigenic relationships of strain KN-4 with strain KK-3 (G10, PB3) as well as with strains NCDV (G6, PB1) and 0...
متن کاملMolecular Characterization and Phylogenetic Analysis of the G6 and G10 Genotypes of Bovine Rotaviruses from Iran
Background and Aims: Rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. Rotavirus G6 and G10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. Materials and Methods: In this work, we have detected the G6 and G10 genotypes of bovine rotaviruses isolated from di...
متن کاملIsolation and G-typing of Rotaviruses from diarrheal Calves in Tehran and Alborz provinces, Iran
Rotaviruses group A are the major cause of diarrhea in calves under one month and every year causes enormous economic losses. Serological and molecular techniques can be used for rapid detection of rotaviruses but virus isolation requires specific methods of cell culture and suitable cell lines. In this study, 41 samples were collected from diarrheal calves up to the age of one month, from indu...
