Molecular characterization of InJR06, a class 1 integron located in a conjugative plasmid of Salmonella enterica ser. Typhimurium Authors José Di Conza Faculty of Biochemistry & Biological Sciences (UNL), Santa Fe, Argentina Juan A. Ayala Center for Molecular Biology “Severo Ochoa” (CSIC-UAM) Cantoblanco, Madrid, Spain Ayelén Porto Faculty of Biochemistry & Biological Sciences (UNL), Santa Fe, Argentina Marta Mollerach Faculty of Pharmacy and Biochemistry (UBA), Buenos Aires, Argentina Gabriel Gutkind Faculty of Pharmacy and Biochemistry (UBA), Buenos Aires, Argentina Keywords: Salmonella Typhimurium, class 1 integron, aminoglycoside, ant(3´´)-Ia, gene cassette Abstract The presence of class 1, 2, and 3 integrons was investigated in four pediatric isolates of Salmonella enterica ser. Typhimurium (S. Typhimurium). A class 1 integron was detected in one S. Typhimurium strain, the only one that also showed resistance to various aminoglycoside antibiotics. This integron, called InJR06, and the aminoglycoside resistance determinants were located in pS06, a large (≥55 kb) conjugative plasmid. Asingle mobile cassette (encoding the aminoglycoside adenylyltransferase ANT(3´´)-Ia) was detected in the variable region of InJR06, while the architecture of the attI1 and attC sites was conserved.
