Detection and characterization of chicken anemia virus in Colombia

Objective. identify the presence of chicken anemia virus (CAV) in poultry farms and backyard chickens from Antioquia, Colombia. Materials Methods. Blood feather samples were taken laying chickens; each farm, three birds six different ages (1, 15, 30, 60, 90, 120 days old) chosen randomly. Backyard also obtained near research farms. We used serology molecular techniques to analyze samples. Results. By PCR, 84% positive whole blood 66% The 60% tested 40% follicle. serology, 22% farm presented high antibody titers 19% moderate titers. In chickens, 43% them 29% addition, results RFLP test sequencing showed that circulating found this study was Cux-1 vaccine strain Conclusions. CAV is present Colombia both commercial chickens. According findings, a percentage for viral detection, whereas number antibodies low. Thus, characteristics need be determined explain response observed study.
