Antimicrobial Resistance Genes

Nineteen Salmonella strains were isolated from 5,907 randomly selected mussel samples during a monitoring programme for the presence of Salmonella in shellfish in Galicia, north-west Spain (2012–16). Serovars, sequence type and antimicrobial resistance genes were determined through genome sequencing. Presence of the mcr-1 gene in one strain belonging to serovar Rissen and ST-469 was identified. The mcr-1 gene had not been isolated previously in environmental Salmonella isolated from mussels in Spain.

ABSTRACT A total of 133 Salmonella isolates recovered from retail meats purchased in the United States and the People's Republic of China were assayed for antimicrobial susceptibility, the presence of integrons and antimicrobial resistance genes, and horizontal transfer of characterized antimicrobial resistance determinants via conjugation. Seventy-three (82%) of these Salmonella isolates were resistant to at least one antimicrobial agent. Resistance to the following antibiotics was common among the United States isolates: tetracycline (68% of the isolates were resistant), streptomycin (61%), sulfamethoxazole (42%), and ampicillin (29%). Eight Salmonella isolates (6%) were resistant to ceftriaxone. Fourteen isolates (11%) from the People's Republic of China were resistant to nalidixic acid and displayed decreased susceptibility to ciprofloxacin. A total of 19 different antimicrobial resistance genes were identified in 30 multidrug-resistant Salmonella isolates. The bla CMY-2 gene, encoding a class A AmpC β-lactamase, was detected in all 10 Salmonella isolates resistant to extended-spectrum β-lactams. Resistance to ampicillin was most often associated with a TEM-1 family β-lactamase gene. Six aminoglycoside resistance genes, aadA1, aadA2, aacC2, Kn, aph(3)-IIa, and aac(3)-IVa, were commonly present in the Salmonella isolates. Sixteen (54%) of 30 Salmonella isolates tested had integrons ranging in size from 0.75 to 2.7 kb. Conjugation studies demonstrated that there was plasmid-mediated transfer of genes encoding CMY-2 and TEM-1-like β-lactamases. These data indicate that Salmonella isolates recovered from retail raw meats are commonly resistant to multiple antimicrobials, including those used for treating salmonellosis, such as ceftriaxone. Genes conferring antimicrobial resistance in Salmonella are often carried on integrons and plasmids and could be transmitted through conjugation. These mobile DNA elements have likely played an important role in transmission and dissemination of antimicrobial resistance determinants among Salmonella strains.

Genotypic Characteristics

We sequenced 35 Salmonella enterica isolates carrying incompatibility group I1 (IncI1) plasmids from different serotypes to study their genotypic characteristics. The isolates originated from food animals (n = 32) and human patients (n = 3). All isolates carried IncI1 plasmids, and many had additional plasmids detected along with virulence and antimicrobial resistance genes.

Sixty-six Salmonella enterica serovar Typhimurium isolates carrying incompatibility group FIB (IncFIB) plasmids were sequenced to further characterize the IncFIB plasmid-encoded factors associated with virulence and antimicrobial resistance genes. In addition to the IncFIB plasmid, many of these isolates harbored additional plasmids encoding virulence and antimicrobial resistance genes.

We report draft whole-genome sequences of two multidrug-resistant Salmonella enterica serovar Senftenberg sequence type 14 strains resistant to ciprofloxacin, ceftriaxone, and/or azithromycin, which were isolated from neonatal stool and goat meat in Kolkata, India. The genome characteristics, as well as the antimicrobial resistance genes, plasmid types, and integrons, are presented in this report.
