The gut microbiome
is highly involved in numerous aspects of host
physiology, from energy harvest to stress response, and can confer
many benefits to the host. The gut microbiome development could be
affected by genetic and environmental factors, including pesticides.
The carbamate insecticide aldicarb has been extensively used in agriculture,
which raises serious public health concerns. However, the impact of
aldicarb on the gut microbiome, host metabolome, and lipidome has
not been well studied yet. Herein, we use multiomics approaches, including16S
rRNA sequencing, shotgun metagenomics sequencing, metabolomics, and
lipidomics, to elucidate aldicarb-induced toxicity in the gut microbiome
and the host metabolic homeostasis. We demonstrated that aldicarb
perturbed the gut microbiome development trajectory, enhanced gut
bacterial pathogenicity, altered complex lipid profile, and induced
oxidative stress, protein degradation, and DNA damage. The brain metabolism
was also disturbed by the aldicarb exposure. These findings may provide
a novel understanding of the toxicity of carbamate insecticides.
