| Abstract |
Gastroenteritis attributable to Salmonella enterica and the continuous increase in antimicrobial resistance of this gut pathogen, which compromises the use of previously effective treatments, is of great concern for public health. This study was conducted in order to investigate the presence of plasmid-mediated quinolone resistance (PMQR) determinants and β-lactamase-encoding genes, in S. enterica, isolated from humans, one companion animal and food. Moreover, the study aimed to identify potential vehicles of transmission of resistant strains to humans, with focus on food products (meat). A total of 20 S. enterica isolates recovered from food (chicken and pork meat), one companion animal and humans (stool samples), were examined for their serotype, antimicrobial susceptibility and the presence of PMQR and β-lactamase-encoding genes. Moreover, the genetic relatedness of nine Salmonella Infantis and ten Salmonella Enteritidis isolates was analyzed by pulsed-field gel electrophoresis (PFGE). Among all isolates, 15 (75%) were multidrug-resistant (MDR) and the majority of them proved to be resistant to nalidixic acid and fluoroquinolones (FQs) (ciprofloxacin and levofloxacin). Twelve isolates (60%) harboured at least one PMQR gene [qnrA, qnrB, qnrS, aac (6')-Ib-cr or qepA] while seven isolates (35%) carried at least one β-lactamase-encoding gene (bla TEM, bla PSE-1, bla SHV or bla CTX-M). Moreover, two or more PMQR or β-lactamase-encoding genes co-existed in a single S. enterica isolate. A number of nine Salmonella Infantis, as well as the majority of Salmonella Enteritidis isolates analyzed by PFGE proved to be closely related. The study demonstrated the co-existence of PMQR and β-lactamase-encoding genes among the Salmonella isolates recovered and confirmed that multiple mechanisms might be involved in the acquisition and spread of resistance determinants. The close genetic relatedness between the clinical and foodborne S. enterica isolates, suggested that chicken meat might be a possible cause of human salmonellosis in our country, during the study period. Results of this study might improve understanding of the antimicrobial resistance mechanisms and transmission dynamics of Salmonella spp. Here, we report for the first time the presence of PMQR and β-lactamase-encoding genes in S. enterica isolates, recovered from humans, one companion animal and food, in Romania. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 June 2015.
All research outputs
#14,689,948
of 22,815,414 outputs
Outputs from Gut Pathogens
#256
of 522 outputs
Outputs of similar age
#142,900
of 263,581 outputs
Outputs of similar age from Gut Pathogens
#5
of 8 outputs
Altmetric has tracked 22,815,414 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 522 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.8. This one is in the 49th percentile – i.e., 49% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 263,581 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
