    Abstract


    In this study, we determined serotypes and antibiotic resistance of Salmonella isolates from several samples (including water samples, caecal contents, and swab samples) collected from two pig slaughterhouses in Hung Yen province) . 43/48 isolates strains were identified as belong to 9 serovars of Salmonella and 5/48 strains that did not identify serotypes. S.derby was the most common 20,83% and then S. typhimurium (18,75), and S. enteritidis (10,42%). Isolated strains in this study are strongly resistant to Streptomycin 96,67%, Tetracyline 83,33%, Ampicillin 63,33%, Trimethoprim 46,67%, Gentamycin 33,33%, Nalidixic acid 36,67%. Samonella isolated strains are susceptible to some new antibiotics such as Nofloxacin, Nitrofurantion , Ciprofloxacin, Ceftazidime.
