Figure 3: Macroscopic lesions and histopathologic sections of chicken intestine with coccidiosis in Central Java. (a) Macroscopic lesion of the caecum showing ballooning condition (arrows) with bloody lumen. (b) Different pinhead size structures were massively formed in lumen of caecum (arrow). (c) Haemorrhagic and inflammatory cells infiltration (arrow) in the infected caecum. (d) Macrogamonts of Eimeria spp. in the caecum (arrows). The species is identified as E. tenella based on the predilection site (caecum), morphology of oocyst, and sporulation time of collected oocysts from faeces.
