Abstract

The common carp ( Cyprinus carpio ) is an invasive species in Argentinian Patagonia. This study aimed to investigate the presence of Circoviridae -related viruses associated with its population in the Negro River. Total DNA samples extracted from the organ pools of 50 individuals were evaluated using a broad-spectrum PCR, which led in a single case to the detection of a circo-like virus. Based on the partial rep sequence obtained, phylogenetic analysis showed a relation between the virus found and those that have been identified in other cyprinid fishes, such as gudgeon ( Gobio gobio ) and fathead minnow ( Pimephales promelas ). The results propose the occurrence of a previously undescribed circo-like virus in Patagonian common carp.
