Abstract

Coccidosis ¡s a disease that causes a lot of huge economic losses for poultry breeders, among others because the mortality rate is quite high, growth retardation, decreased egg production and feed efficiency and high treatment costs and labor costs [1]. One of pathogenic Elmeria species is E. tenella that cause cecal coccidiosis. The fact that there is the poultry industry, the control of coccidiosis is mostly associated with the use of routine anti-coccidiosis (coccidiostat). To overcome these conditions the option to conduct immunization approach (immunization) against chicken in controlling the disease more intensive and planned indispensable. Immunization against chickens to control coccidiosis more promising in avoiding or decreasing the reliance on the use of chemicals and other coccidiostat The previous study already constructed attenuated E. tenella isolate by serial passages in naïve chicken. The present study ¡s to prove reduction of pathogenicity of those isolate
