Variation of butirylcholinesterase levels a Mexican population in different periods of control of Aedes spp.

Abstract

The impact of organophosphate and carbamate pesticides used to control the Aedes spp. mosquito in sanitary campaigns was determined by measuring serum butirylcholinesterase activity in dry and rainy seasons. Differences in levels and their trend over time were analyzed, finding statistically significant differences between both seasons (men: dry season = 5272 U/L; rainy season = 4854 U/L; p < 0.05), with a decrease of 92 U/L each month. The decrease in men was 92 U/L each month. The enzymatic inhibition may be due to exposure to these anticholinesterase insecticides, and protective measures must be taken against the related health risks.
