Histopathological findings and apoptosis caused by E. coli in layer birds

In this study, our aim was to evaluate lesions seen in the tissues in terms of histopathology and to investigate the apoptotic cells seen in the tissues when E. coli outbreak occurred in a poultry farm. A total of 48 Lohmann White strains (53 weeks old) were submitted to the laboratory for necropsy. Microbiologic and histopathologic examinations were done on the samples taken from tissues. Apoptotic cells were determined in all of the tissues. The number of apoptotic cells increased as the tissue damage increased
