The present study investigated the antimicrobial behaviour of E. coli and Salmonella spp. strains, isolated from pigs after their weaning age. Antimicrobial testing susceptibility by the Kirby-Bauer method allowed the identification of bacterial strains with multiple antibiotic resistance (58.02% for E. coli isolated strains and 47.27% for Salmonella isolated strains). Thus, it was noted that all 54 strains of E. coli showed resistance to trimethoprim; sulfathiazole with sulfacetamide and sulfabenzamide; sulphametoxazol with trimethoprim; ciprofloxacin and nalidixic acid; more than 95% of the strains were resistant to streptomycin, ampicillin and kanamycin. Over 60% of Salmonella spp. strains were resistant to lincomycin, streptomycin, tetracycline, and flumequine. The lowest bactericidal activity was attributed to lincomycin, 90.90% of the Salmonella isolates being reistant to this antimicrobial. Regarding the sensitivity of E. coli isolated strains, over 85% showed sensitivity to ceftazidime, aztreonam and imipenem. Between 50% - 60% of Salmonella strains were sensitive to gentamicin, cefotaxime, and amikacin, while less than 50% of the isolates were susceptible to the rest of the studied antibiotics.
