Nebraska calf diarrhea virus.
Specificity
Reacts with rotavirus and is specific for ICPs and late structural (virion) antigens. It has been reported to exhibit 90% cross reactivity with human rotavirus and does not react with HEp-2 cells or WI-38 cells in immunofluorescence. Rotavirus is a virus that infects the bowels and is the most common cause of gastroenteritis in infants. 7 major groups have currently been identified, 3 of which infect humans (groups A, B and C). The rotavirus genome consists of 11 segments of double stranded RNA held in the inner core of the three layered, icosahedral virion particle. The genome codes for 6 virus proteins (VP1,2,3,4,6,7) and 6 non-structural proteins (NSP1-6). Outer capsid proteins are VP4 and VP7, inner capsid -VP6 and core -VP2. The immunity acquired from exposure to rotavirus appears to be type specific following initial infection; therefore, multiple serotypes of rotavirus mean multiple opportunities for infection.
