Resumen:
This work is a partial requirement for the degree of Veterinarian UFCG / CSTR
and the theme was a literature review on anthelmintic resistance in sheep and goats in
northeastern Brazil. Were analyzed scientific articles, books, technical notes and
circulars published in different regions of Brazil. The data obtained showed that
gastrointestinal parasitosis of goats and sheep and cause serious economic losses. The
frequent use and misuse of anthelmintics is a major cause of the emergence of
anthelmintic resistance that currently occurs throughout the country and has been
registered ever more frequent. Were presented which are the main predisposing factors
for the occurrence of resistance and demonstrated succinctly what measures should be
used to minimize the loss of efficacy of anthelmintic drugs and the procedures for the
efficient control of parasitic diseases in herds. It was concluded that the lack of
knowledge on the part of producers and technicians of the factors that lead to
anthelmintic resistance, as well as measures to reduce contamination of pastures and
consequent infection of animals, leads to excessive use of anthelmintics and the
increasing resistance anthelmintic.
