A natural case of delayed neurotoxicity by pesticides in bovines of lbague Tolima (Colombia) is reported. 17 adults zebu cattle showed posterior limbs
ataxia, progressive paralisis, lateral decubitus muscular
atrophy and opisthotonos. From those animals only

The eight animals were slaughtered and toxicologic
and histopathologic analysis were carried out. Inhibition of blood colinesterase and high concentrations of
carbamates and organochlorides in viscera nervous
and muscular tissues were demonstrated as well as
nervous and muscular lesiones were seen.En Ibagué, Tolima (Colombia), se estudió un caso de ocurrencia natural, en el cual 17 bovinos cebú presentaron ataxia de miembros posteriores, parálisis progresiva con atrofia de masas musculares, decúbito lateral y opistótonos.
