Serological comparisons of avian reoviruses

Serological characteristics of avian reoviruses of Australian origin

“…A similar one-way neutralisation occurred between 74/13 (subtype A) and the three viruses defined as subtype B and two viruses in subtype C. Similar oneway neutralisation by avian reoviruses was previously reported by Wood et al (1980) and Hieronymus et al (1983).…”

“…Sahu and Olson (1975) confirmed this observation when they classified nine U.S. isolates into four types using a constant virus-varying serum plaque reduction technique. Wood et al (1980) compared the reovirus strain SI 133, which has been used in vaccination trials in the U.S.A. (Rau et al, 1980), with five other reoviruses from the U.K., Germany and U.S.A. On the basis of virus neutralisation tests they grouped the six strains into three serotypes. Prototype strains of these three groups (including SI 133) were then compared with the five Japanese serotypes of Kawamura et al (1965) and the four U.S. serotypes of Sahu and Olson (1975) and they were able to show that there were at least 11 avian reovirus serotypes.…”

Routine virus isolation or detection in the diagnosis of diseases in birds

“…Reoviruses have been associated with clinical disease in parrots showing hepatic lesions on post-mortem (Meulemans et al, 1983;Ashton et al, 1984;Graham, 1986), but in only one of the cases in the present study was the isolate made from a parrot with hepatitis. Eleven avian reovirus serotypes have been described (Wood et al, 1980) but because of the lack of correlation with disease it was not considered worthwhile serotyping the reoviruses isolated in the present study. Because of the widespread presence of these viruses in avian tissues and the ease with which they replicate in cell culture systems it was felt that on occasion they may have prevented the detection of more fastidious viruses that may have been present and responsible for the disease under investigation.…”

Enteric viruses in turkey flocks: a historic review

“…Different authors demonstrated the neutralizing effect of poult serum recovered from blue comb disease in young poults inoculated with an intestinal suspension of affected flocks (Sieburth & Johnson, 1957;Tumlin & Pomeroy, 1958) and in HE outbreaks, preventing and reducing losses (Domermuth & Goss, 1975). The test was also used to demonstrate different serotypes of turkey adenovirus (Scott & McFerran, 1972;McFerran et al, 1975), rotavirus (McNulty et al, 1980b) and reovirus (Kawamura et al, 1965;Sahu & Olson, 1975;Wood et al, 1980). As neutralization tests were considered timeconsuming and expensive, because they depended on the development of infection in poults , several other serological techniques were evaluated.…”
