Abstract

The aim of the research was to find out the histopathological appearance of chicken caecum due infected by Eimeria tenella oocyst that attenuated through the serial passage. This research used histopathological scores and the number of schizont to show the changes due attenuated E. tenella. Twenty four male chickens were divided into four groups and each group consisted five male chickens as repetition and one male chicken as a control. The first group was infected by E. tenella parent lines, the second group was infected by precocious lines E. tenella of the first group, the third group was infected by precocious lines E. tenella of the second group, then the fourth group was infected by precocious lines E. tenella of the third group. The feces samples was proccessed by sediment and floating method. Histopathological score and the total number of schizont were examined under microscope with magnification 400-1 OOOx. The result showed that there was significantly difference (p<0.05) in the score of hemorrhage between the first, second, third and fourth group. The score of caecum epithel erosion showed significantly difference (p<0.05) between the first, second, third, and fourth group. The number of schizont showed significantly difference (p<0.05) between the first, second, third, and fourth group. Moreover, attenuation through serial passag~ decrease injury levels of histophatological chicken caecum and the number of schizont.
