Table 2 Distribution of phage types, multidrug resistance, PFGE profiles and MLVA types among the 375 STM isolates from the domestic infections

From: Characterization of Salmonella Typhimurium isolates from domestically acquired infections in Finland by phage typing, antimicrobial susceptibility testing, PFGE and MLVA
