The objjectt of tthiis sttudy was focused on ttransmiissiion of Liitteriia monocyttogenes tthrough llayer body ,, tthe rolle of tthiis biirds iin tthe spread of tthiis bactteriia and tthe effectt of experiimenttalllly iinfecttiion dose of tthe llayer oralllly on bactteriia transmiitttted tto eggs ,,egg componentts and iintternall organs .. A ttottall of 45 llayer were diisttriibutted iintto tthree groups and each group tto tthree replliicattes (15 llayer per replliicatte) cosnsiistted of T1 (conttroll group free of iinfecttiion) ,, T2 and T3 were oralllly experiimenttalllly iinfectted by 1x105 and 1x1010 (CFU \\ mll \\ hen of L.. monocyttogenes .. Resulltts iindiicatted tthatt ..L.. monocyttogenes were iisollatted from ovary,, oviiductt,, utterus,, proventtiicullous,, giizzard,, heartt,, lliiver,, splleen,, iinttesttiine and cecum aftter 3,, 6,, 9,, 15and 21 days of experiimenttalllly iinfecttiion and tthe llowestt iisollatted ratte from T2 group compared wiitth T3 group ..Allso ,, tthe bactteriia were iisollatted from egg shellll ,, shellll membrane and egg allbumen of eggs produced from T2 and T3 group llayers aftter 3,, 6,, 9,, days and tthe iisollattiion ratte decreased gradualllly from tthe tthree componentts of tthe egg aftter 15 days ,,when as tthe iisollattiion from yollk membrane ,, yollk flluiid and germiinall cellll aftter 6 days of iinfecttiion and decreased gradualllly aftter 21 days ..
