Detection of a novel circo-like virus in common carp from Argentinian Patagonia

Abstract

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