Cold plasma treated thyme essential oil/silk fibroin nanofibers against Salmonella Typhimurium in poultry meat

This study aims to fabricate cold plasma treated thyme essential oil (TO)/silk fibroin (SF) nanofibers to inhibit Salmonella Typhimurium in poultry meat. Firstly, antimicrobial activity and mechanism of TO against Salmonella Typhimurium was assessed. Subsequently, viscoelastic properties of spinning solutions and properties of nanofibers which included nanofibers stability, hydration, barrier and mechanical properties were studied to screen good performance nanofibers. Further, cold plasma was applied to implement the surface modification of TO/SF nanofibers. The results showed that the TO release amount of plasma-TO/SF nanofibers improved obviously after cold plasma treatment, leading to higher antibacterial activity of plasma-TO/SF nanofibers than TO/SF nanofibers. After plasma-TO/SF nanofibers treatment, the number of Salmonella Typhimurium in chicken meat and duck meat decreased by 6.1 and 6.06 Log CFU/g compared with control group at 25 °C, respectively. Overall, this study indicated that plasma-TO/SF nanofibers membrane was an effective antimicrobial packaging to increase shelf life of foods, which had a broad prospect in the field of food preservation.Graphical abstract

Little is known about enteropathogen seroepidemiology among children in low-resource settings. We measured serological IgG responses to eight enteropathogens (Giardia intestinalis, Cryptosporidium parvum, Entamoeba histolytica, Salmonella enterica, enterotoxigenicEscherichia coli,Vibrio cholerae, Campylobacter jejuni, norovirus) in cohorts from Haiti, Kenya, and Tanzania. We studied antibody dynamics and force of infection across pathogens and cohorts. Enteropathogens shared common seroepidemiologic features that enabled between-pathogen comparisons of transmission. Overall, exposure was intense: for most pathogens the win...

Schlossmacher, Subash SadAbstractReceptor interacting protein kinase 3 (Ripk3) is a signal relay protein involved in initiation of programmed cell death (necroptosis) and modulation of inflammasome activation. While caspase 1 and 11 are pro-inflammatory caspases responsible for unleashing inflammation and cell death by enzymatic activation of the executioners of inflammation and cell death (pyroptosis). Upon Salmonella infection, the host mounts a pro-inflammatory respon...

In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...

Conclusion: We found that raw milk samples were not free of Salmonella spp. and Shigella spp. and need to be tested routinely to avoid public health problems. Rapid and reliable real-time PCR method can be developed and used for this purposes instead of slow bacterial culture processes.

Sztein Enteric fevers, caused by theSalmonella enterica serovars Typhi (ST), Paratyphi A (PA) and Paratyphi B (PB), are life-threatening illnesses exhibiting very similar clinical symptoms but with distinct epidemiologies, geographical distributions and susceptibilities to antimicrobial treatment. Nevertheless, the mechanisms by which the host recognizes pathogens with high levels of homology, such as these bacterial serovars, remain poorly understood. Using a three-dimensional organotypic model of the human intestinal mucosa and ...

Among antimicrobials, critically important ones are therapeutic drugs that should be primarily safeguarded to allow successful outcomes against important bacterial infections in humans. The most important source of antimicrobial resistance has been recognized in the inappropriate use of antimicrobials in hu...
