Abstract: One hundred and twenty chicks were collected from twenty-one broiler flocks raising 130000 birds from different localities in North Sinai Governorate. The chickens were either diseased or freshly dead. Some bacteria were isolates from the reserved birds and identified as (72) E.coli, (34) Klebsiella spp., (31) Proteus spp., (19) S.aurous spp., (8) Pseudomonas aeruginosa and (11) Salmonella spp.. Some strains of E.coli and Salmonella species were typed serologically. Experimental infection of day -old broilers chicken which with representative isolate from each 4 genera was carried out.
The clinical signs and macro-pathological findings varied according to the type of microorganism.
Microscopically, the liver of birds showed focal coagulative necrosis and congestion of hepatic blood vessels. The heart of infected birds revealed fibrinous pericarditis represented by congestion, fibrin threads, and fibrinous tissue proliferation with leukocytic infiltration, and the spleen showed focal coaguiative necrosis of the splenic tissue. In addition the intestines of the infected birds showed desquamations of the villus epithelium with leukocytic infiltration in the mucosa and sub- mucosa.
The antibiogram for E.eoli isolates revealed that they were all sensitive to Gentamycin, Norfloxacin, Colistin sulphate and variably sensitive to antibiotics used in the test.
