Of the 24 antimicrobials tested, the isolates showed resistance to 4 to 10 of them. Most frequently, the isolates showed resistance to\u00a0 sulfonamides (Su), ampicillin (A), streptomycin (S), spectinomycin (Sp), chloramphenicol (C), tetracycline (T), and florfenicol (F). Thirteen resistance patterns were observed with 88% of\u00a0 the isolates presenting with the resistance pattern &#8220;ACSpSSuT.&#8221; Plasmid profiles were investigated and the isolates were classified into 23 distinct genotypes by PFGE-SpeI 1 BlnI. \u00a0In total, 39 distinct \u201ctypes\u201d were observed when a \u201ctype\u201d was based on antimicrobial resistance, plasmid pattern, and PFGE-SpeI 1 BlnI for each isolate. In conclusion, the diversity of isolates discovered suggessts the\u00a0<em>Salmonella <\/em>Typhimurium DT104 strains come from multiple sites on the swine farms. These findings can be used to determined the exact source of contamination as well as to trace\u00a0<em>Salmonella <\/em>Typhimurium DT104 infections in humans back to the source either swine-related or from other food-producing animals.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This study investigated antimicrobial resistance of 80 Salmonella Typhimurium DT104 strains on 17 commercial swine farms in Ontario.
