Abstract
Objetive: To evaluate the response of CAT, AChE and GST enzymatic biomarkers in Zenaida Asiatic from an agricultural area of the municipality of Champotón, Campeche.
Design/methodology/approach: The biomarkers AChE, CAT and GST were analyzed in tissues of 24 birds from backyards and agricultural areas of Champotón, Campeche. The enzymatic activities in the tissues were compared by means of a t test and comparison of means (Tukey P≤0.05), with the Statistica vs 7 software.
Results: The highest AChE activity occurred in the brain (p=0.00001), CAT in liver (p=0.00001) and GST in liver and brain (p=0.001).
Limitations on study/implications: To evaluate the effect of pesticides on wild birds, a larger number of individuals is required in different agricultural areas.
Findings/conclusions: In the tissues of Z. asiatica from agricultural areas, greater activity of the biomarkers AChE, CAT and GST was found, reflecting the excessive use of pesticides.
