| Poultry production is an activity of great importance in Brazilian economy, both due to the domestic consumption and the large amount of chicken meat exportation. Poultry activity modernization allowed the creation of animals in high density facilities, however, it facilitates the rapid dissemination of pathogens, which reduces the productivity rates. This review aims to highlight the avian reovirus, an important agent of arthritis in birds that has a worldwide distribution. The affected birds present a reduction in weight gain due to movement difficulties. In addition to arthritis, the virus may be related to a variety of pathological conditions, such as enteric and respiratory disorders, Hepatitis and myocarditis. The main prevention and control measure... |

| Fifty-four fecal samples taken from broiler chickens from 1 to 45 days of age, and of pullets from 10 to 13 weeks of age, original from eight different poultry regions in the state of Minas Gerais, Brazil, were collected from March 2008 to January 2010 for avian Orthoreovirus (ARV) and avian Rotavirus (AvRV) analyses. For the assay of ARV, RNA was immediately extracted (Trizolâ) and transcribed into cDNA for assaying in a nested-PCR with ARV-specific primers. For AvRV, polyacrylamide gel electrophoresis (PAGE) was performed with RNA extracts obtained by phenol-chloroform extraction. CAV was additionally investigated through a nested-PCR of thymus and spleen. Results found 5.55% positive for ARV and 9.25% for AvRV. Also, CAV and ARV genomes were detected in... |
