Ceftriaxone-Resistant Salmonella enterica Serotype Newport, France
نویسندگان
چکیده
The multidrug-resistant (MDR) Salmonella enterica serotype Newport strain that produces CMY-2 beta-lactamase (Newport MDR-AmpC) was the source of sporadic cases and outbreaks in humans in France during 2000-2005. Because this strain was not detected in food animals, it was most likely introduced into France through imported food products.

DNA sequence analysis of regions surrounding blaCMY-2 from multiple Salmonella plasmid backbones.
The emergence in the United States of resistance to expanded-spectrum cephalosporin (e.g., ceftriaxone) within the salmonellae has been associated primarily with three large (>100-kb) plasmids (designated types A, B, and C) and one 10.1-kb plasmid (type D) that carry the blaCMY-2 gene. In the present study, the distribution of these four known blaCMY-2-carrying plasmids among 35 ceftriaxone-res...
متن کاملEmergence of multidrug-resistant Salmonella enterica serotype Newport infections resistant to expanded-spectrum cephalosporins in the United States.
We describe a field investigation in New England that identified the emergence and epidemiology of new strains of multidrug-resistant Salmonella, Newport-MDRAmpC, and summarize the Center for Disease Control and Prevention's surveillance data for these infections. In Massachusetts, the prevalence of Newport-MDRAmpC among Salmonella serotype Newport isolates obtained from humans increased from 0...
متن کاملAssociation between handling of pet treats and infection with Salmonella enterica serotype newport expressing the AmpC beta-lactamase, CMY-2.
Resistance to the extended-spectrum cephalosporins can occur in Salmonella species via the production of extended-spectrum and AmpC beta-lactamases. We describe human infections with Salmonella enterica serotype Newport phage type 14 strains resistant to ceftazidime (CAZ) and cefoxitin (FOX) related to the handling of pet treats containing dried beef. These strains were isolated from five patie...
متن کاملComplete Sequences of Six IncA/C Plasmids of Multidrug-Resistant Salmonella enterica subsp. enterica Serotype Newport
Multidrug-resistant (MDR) Salmonella enterica subsp. enterica serotype Newport has been a long-standing public health concern in the United States. We present the complete sequences of six IncA/C plasmids from animal-derived MDR S. Newport ranging from 80.1 to 158.5 kb. They shared a genetic backbone with S. Newport IncA/C plasmids pSN254 and pAM04528.
متن کاملAntimicrobial resistance genes associated with Salmonella enterica serovar newport isolates from food animals.
Salmonella enterica serotype Newport is an important cause of salmonellosis, with strains increasingly being resistant to multiple antimicrobial agents. The increase is associated with the acquisition of multiple resistance genes. This study characterizes the genetic basis of resistance of serotype Newport isolates collected from veterinary sources by PCR and DNA sequencing analysis.
