Abstract
The role of avian reoviruses in the atiology of certain disease conditions encountered in commercial broilers includIng uneven growth and stunting, feathering abnormalities, eteric disorders, brittle bones, proventriculitis, lameness a:d tenosynovitis was investigated.
Serologica screenin.- of 5C (31 ap reml’ helthy s: 19 flseased) con2ercial broileD flocks at? 5 “:ee::s of age, raised in 3 governoratos in ITorthern Tile Delta - (Alexandria, Behera and Kafr 2l—Shiekh), for avian reovi— rus antIbody by the agar gel precipitation test (AGP) detonstrcted the viidespread nature of this infection. Thirtr fit’e Larms (70%) had serum precipitating antibody to avit: reovirus 8—1133 antigen. The incidence of AGP2 reactors ran3e’i between 2.5 and 93.3% among the flocks and constituted 25.6% of the total number of sera e:rarii— ned (1737 serum sample).
Reoviru.s isolation was atteapted on liver vid intestinal contents as well as on les joint fluid and tendon collected from 57 commercial broiler farms of 2 — 7 weeks of age raised in the Northern area of the file Delt.i.
