A total of 136 organs Samples were collected from broiler chickens were post mortem lesion of colisepticaemia Bacteriological examination of the samples and isolation or E. coli were carried out. The Table (3): Percentage of E coli isolates recovered fromThe Table (5): Showing biochemical reaction of E coli. The strainsuniformly produced Positive indole, methyl red. Negative voges- proskaur, citrate medium. They did not cause break down of urea nor liquefy gelatin produced H2S. The Table (6): Showing serotypes of E. coli isolated from farms: showed that the most prevale0114= 4 and 0158= 4). The Table (7): E col i servers’ isolated from deferent Governorates: (Alexandria: 0111,015,0118 and 044). (Cairo: 0128,0114,0112, 015,078,0103,0118,0124,091 and 0158). (EL sherikh: 0111, 057 and 0158). (Ismailia: 0114, 057, 078 and 006 and 0142). (EL rnanofia: 0128 and 078). (AIgharbia: 091 and0158). The Table (8 a,b,c,d,e,f,g,h and i) Neutrophil dysfunction wasstudied there was decrease in neutrophil phagocytes against staphaureus. Alteration in neutrophil function during bacterial infection has been variously reported as either increased or decreased depending on theparameter measured, the technique used, and the nature of theinfection. Neutrophil function disorders are caused by defected in neutrophil adherence, chemo taxis, degranulation or oxidative metabolism.
