Summary: | The genus Eimeria belonging to the Subphylum Apicomplexa, Family Eimeriidae, have seven recognized species infecting chickens: E.acervulina, E. maxima, E.tenella, E.brunetti, E.necatrix, E.mitis and E.praecox. It’s an obligate intracellular parasite that causes disease by the destruction of intestinal epithelial cells in the replication process. The indiscriminate use of anticoccidial drugs has resulted in the selection of drug-resistant strains, which reduce de effectiveness of various anticoccidial drugs used currently in control of the disease. As in many countries legislation prohibits the use of thes products continuously until slaughter withdrawal periods have been required, which increases the risk of infection at the end of the growing season. Thus, vaccines are essential as a tool for controlling these parasites. There are several types of vaccines, but only attenuated live vaccines are marketed for the control of avian coccidiosis, with the exception of recombinant vaccine CoxAbic®. Nevertheless, its use is still mild compared to the use of anticoccidial drugs, possibly due to its lower cost and greater effectiveness. Thus, it is important that control of avian coccidiosis is extremely complex, and that further studies should be encouraged to develop effective methods, including the use of vaccines for the production of chicken meat free of medication. |

Trata-se de um parasito intracelular obrigatório que causa doença pela destruição de células do epitélio intestinal em seu processo de replicação. O uso indiscriminado de anticoccídicos tem resultado na seleção de cepas resistentes a drogas, as quais reduzem a eficácia de vários anticoccídicos usados atualmente no controle dessa parasitose. Como em muitos países a legislação proíbe o uso destes produtos continuamente até o abate, períodos de retirada têm sido exigidos, o que aumenta o risco de infecção no final do período de crescimento. Desta forma, as vacinas são fundamentais como ferramenta de controle destes parasitas. Existem atualmente diversos tipos de vacinas, porém somente vacinas vivas e atenuadas são comercializadas para o controle da coccidiose aviária, com exceção da vacina recombinante CoxAbic®. Apesar disso, o seu uso ainda é discreto frente ao uso de anticoccidianos, possivelmente devido a sua menor eficácia e maior custo. Desta forma, é importante ressaltar que o controle da coccidiose aviária é extremamente complexo, e que, novos estudos devem ser estimulados para o desenvolvimento de métodos eficazes, entre eles o uso de vacinas, para a produção de carne de frango livre de medicamentos.UEL2012-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRevisão de Literaturaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/887610.5433/1679-0359.2012v33n3p1165Semina: Ciências Agrárias; Vol. 33 No. 3 (2012); 1165-1176Semina: Ciências Agrárias; v. 33 n. 3 (2012); 1165-11761679-03591676-546Xreponame:Semina.
