Five out of eleven(54.5%) E.coli isolates from layers isolates were sensitive to spectam. this result agreed with that obtained by Eltahawy (1997) who noted that all Gram-negative bacilli isolates were resistant to at least two of the four major antibiotics group (aminoglocoside, fluoroquinolon, third generation cephalosporin and carbapenems). Our study revealed that all Salmonella isolates were sensitive to cefotaxime. This result agreed with Jamal et al.,( 1998) and Juncosa Morros et al., (2005) who reported that cefotaxime sensitivity for Salmonella isolates were 99.7% and 99.9% respectively. All Salmonella isolates from layer were sensitive to ciprofloxacin. This result agreed with Jacobs-Reitsma et al.,(1994), Poppa et al.,(1995) and Juncosa Morros et al., (2005) who found that all Salmonella isolates were sensitive to ciprofloxacin also, this result agreed with Babirake-Iriso et al.,(2006) who found that sensitivity to ciprofloxacin was 97%, variable values 91.5% and 93.33%) were obtained by David et al.,(1996) and Hui and Das (2001) respectively. 1 out of 2(50%) Salmonella isolates from layer were sensitive to ampicillin, this result agreed with that obtained by Giurov (1985) who recorded that ampicillin sensitivity percentage was 51.12% and Dinch 88
and Nguyen (1995) who reported moderate sensitivity to ampicillin also, this result agreed with Abd-El-Mawla (1998) who recorded sensitivity percentage 50% for ampicillin. 1 out of 2(50%) Salmonella isolates from layer were sensitive to gentamycin this result agreed with that obtained by El-Ghamdi et al.,(1999) who recorded from resistance percentage ranged from 57% to 99.1% for gentamycin also, Lambie et al., (2000) reported that the isolates showing increasing trend of resistance to amoxicillin, paramecia, gentamycin, nitrofurance, norfloxacin and sulfamethazole/trimethoprime. No Salmonella isolates were sensitive to sulfamethazole/ trimethoprime. this means that sulfamethazole/trimethoprime resistance percentage was 100%. This result agreed with that obtained by Poope et al.,(1995) who recorded sensitivity percentage 1.7% for sulfamethazole /trimethoprime and agreed with Lambie et al., (2000) who reported resistance for sulpha. And disagreed with resistance percentage 73.3% which obtained by El-Sayed (2001). No Salmonella isolates were sensitive to colistin this means resistance percentage 100%, this result agreed with Saha et al (1992) who found that Salmonella typhimuriun isolates showed resistance against commonly used antimicrobial agents. 89
