Colibacillosis and Salmonellosis are diseases which threat poultry industry and cost poultry producers and related industries millions of dollars a year. The principles of controlling such diseases are based on a combination of biosecurity measures and the use of antibiotics. This study was carried out to determine the in vitro sensitivities of isolated strains of Salmonella and E.coli from poultry operation units to different antibiotics commonly used in the field as a tool for application of effective biosecurity program in poultry farms. For this purpose, identified Salmonella and E.coli serotypes isolated from poultry farms and hatcheries were tested against 14 antibiotics. Our results revealed that all isolated strains were 100% sensitive to amikacin, nitrofurantion, chloramphenicol, polymyxin B, ceftriaxone and enrofloxacin . On the other hand, all of tested strains exhibited absolute (100%) resistance against streptomycin, neomycin and nalidixic acid. These results indicated the role of antibiotics in controlling such diseases but at the same time, directed our care to find alternative means for control to avoid antibiotic-resistant bacteria. ,
