Avian reovirus infection is prevalent in intensive poultry farming, especially in broilers, wich evolve with many anatomoclinical forms. The researches was carried out in a flock of 10500 broilers,from Cobb hybrid. This flock was monitored until the age of 41 days, by clinical and anatomopathological exams, performed biweekly. The results were processed and graphically presented. The tests performed were identified following anatomoclinical forms of reovirosis: arthritis- tenosynovitis, ascites, hidropericard, proventriculus inflammation, catarrhal enteritis and necrosis of the femoral head uni and bilateral. Arthritis- tenosynovitis appeared at the age of 19 days maintaining in a relatively constant frequency until the end of the experiment. Ascites occurred at the age of 26 days with a frequency of between 12.5% and 20%. The hidropericard appeared at the age of 26 days, with a frequency between 12.5% and 42.85%. Catarrhal enteritis was reported at the age of 12 days, with a maximum frequency of 57.14%. Femoral head necrosis was signaled from the age of six days in both forms(unilateral and bilateral). Unilateral necrosis had a frequency of 42.85% at the age of 41 days and bilateral had necrosis has the frequency of 71.42% at the age of 21 days. The results obtained showed reovirosis evolution in broilers, in several clinical forms, confirmation of the disease was demonstrated by the polymerase chain reactionreverse transcriptase.
