The results show theres no characterstic signs in infected chickens except depression,anoxia&and theres marked decrease of egg production, qualititativly & quantitativly. L.monocytogenes isolated from egg ( shell, ,yolk,albumine)&persiste to (31,28&19) dayses respectively,also Listeria isolate from ovary&oviduct in chickens which killed in (7,15,24,30)day,¬ isolate from chickens that killed in day (39,34,42)or in control.
