| emergence of multidrug resistance in locally-acquired human infections with salmonella typhimurium in australia owing to a new clade harbouring blactx-m-9. | antimicrobial resistance in non-typhoidal salmonella is a critical problem globally, with the emergence of resistance to third-generation cephalosporins (3gcs) a particular concern. the aim of this study was to use whole-genome sequencing (wgs) to characterise recently identified human and non-human isolates of 3gc-resistant salmonella enterica subsp. enterica serovar typhimurium from australia. the illumina nextseq sequencing platform was used to determine the genome sequences of 78 s. typhimur ... | 2017 | 28476613 |
| temporal genomic phylogeny reconstruction indicates a geospatial transmission path of salmonella cerro in the united states and a clade-specific loss of hydrogen sulfide production. | salmonella cerro has become one of the most prevalent salmonella serotypes isolated from dairy cattle in several u.s. states, including new york where it represented 36% of all salmonella isolates of bovine origin in 2015. this serotype is commonly isolated from dairy cattle with clinical signs of salmonellosis, including diarrhea and fever, although it has also been identified in herds without evidence of clinical disease or decreased production. to better understand the transmission patterns a ... | 2017 | 28507536 |
| ca(2+) in hybridization solutions for fluorescence in situ hybridization facilitates the detection of enterobacteriaceae. | fluorescence in situ hybridization (fish) has been employed to identify microorganisms at the single cell level under a microscope. extensive efforts have been made to improve and extend the fish technique; however, the development of a widely applicable protocol is a continuing challenge. the present study evaluated the effects of divalent cations in the hybridization solution on the fish-based detection of various species of bacteria and archaea with rrna-targeted probes. a flow cytometric ana ... | 2017 | 28515389 |
| mitigation of salmonella on pet food kibbles by using liquid and powdered 3-hydroxy-3-methylbutyric acid. | in recent years, several pet food recalls have been attributed to salmonella contamination. in addition to the negative impacts on animal health, salmonella-contaminated pet foods have been linked to infection in humans. with that in mind, the u.s. food and drug administration has set forth a zero-tolerance policy for salmonella in pet foods. typically, pet foods are extruded or processed at high temperatures that are sufficient to reduce pathogenic bacteria. however, the possibility for postext ... | 2017 | 28561638 |
| susceptibility of salmonella biofilm and planktonic bacteria to common disinfectant agents used in poultry processing. | poultry contaminated with salmonella enterica subsp. enterica are a major cause of zoonotic foodborne gastroenteritis. salmonella heidelberg is a common serotype of salmonella that has been implicated as a foodborne pathogen associated with the consumption of improperly prepared chicken. to better understand the effectiveness of common antimicrobial disinfectants (i.e., peroxyacetic acid [paa], acidified hypochlorite [ach], and cetylpyridinium chloride [cpc]), environmental isolates of nontyphoi ... | 2017 | 28561639 |

| molecular subtyping of salmonella typhimurium with multiplex oligonucleotide ligation-pcr (mol-pcr). | a multiplex oligonucleotide ligation-pcr (mol-pcr) assay is a valuable high-throughput technique for the detection of bacteria and viruses, for characterization of pathogens and for diagnosis of genetic diseases, as it allows one to combine different types of molecular markers in a high-throughput multiplex assay. a mol-pcr assay starts with a multiplex oligonucleotide ligation reaction for detection of the molecular marker, followed by a singleplex pcr for signal amplification and analysis of t ... | 2017 | 28600761 |
| a role for the tetraspanin proteins in salmonella infection of human macrophages. | infected macrophages play a role in the dissemination of salmonella and may serve as a reservoir of infection in asymptomatic carriers. however, relatively little is known about the early molecular interactions of the bacteria with these cells. we have recently shown that members of the tetraspanin family of membrane proteins are involved in the initial adhesion of a range of bacteria to host cells. this study investigated the role of tetraspanins in salmonella enterica subsp. enterica serovar t ... | 2017 | 28602860 |

| relationship of triamine-biocide tolerance of salmonella enterica serovar senftenberg to antimicrobial susceptibility, serum resistance and outer membrane proteins. | a new emerging phenomenon is the association between the incorrect use of biocides in the process of disinfection in farms and the emergence of cross-resistance in salmonella populations. adaptation of the microorganisms to the sub-inhibitory concentrations of the disinfectants is not clear, but may result in an increase of sensitivity or resistance to antibiotics, depending on the biocide used and the challenged salmonella serovar. exposure of five salmonella enterica subsp. enterica serovar se ... | 2017 | 28696348 |
