QUIROZ HERRERA, Victor Hugo  y  PALACIO BAENA, Jaime. Genotoxic Biomarkers in Erythrocytes of Lepidochelys olivácea (Cheloniidae) from Colombia. Acta biol.Colomb. [online]. 2017, vol.22, n.3, pp.322-330. ISSN 0120-548X.  https://doi.org/10.15446/abc.v22n3.58688.

This research was conducted in the municipality of Bahia Solano, Colombia, and had as a goal to detect damage erythrocytes circulating with nuclear lesions in fifty-five Olive Ridley adult females using acridine orange immunostain, and correlate its frequencies with some physiological and biometric parameters. We determine a micronucleated erythrocytes (MNE) frequency of 0.6 ± 0.6 and nuclear buds (NBE) of 2.1 ± 1.9. We not found any relationship between the nuclear lesions with physiological or biometric parameters evaluated (Pearson and Kruskal-Wallis, p<0.05). We define a significative statistical difference (p=0.035) between both nuclear lesions frequencies. This results show nuclear damages in erythrocytes of Olive Ridley sea turtle for the first time in Colombia as an outcome of genotoxic stress. Also contributes key information for future research in the ecotoxicology area for endangered marine species.
