The Czech Republic is free to take the necessary steps against the risk of imports of Polish beef that could be infected with salmonella, but the measures have to be proportionate to the risk, the European Commission said on Friday.

oslash;ller Aarestrup Martha J. Vives Bacteriophages represent an alternative solution to control bacterial infections. When interacting, bacteria and phage can evolve, and this relationship is described as antagonistic coevolution, a pattern that does not fit all models. In this work, the model consisted of a microcosm of Salmonella enterica serovar Enteritidis and φSan23 phage. Samples were taken for 12 days every 48 h. Bacteria and phage samples were collected; and isolated bacteria from each time point were challenged against phages from previous, contemporary, and subsequent time points. The phage plaque...

Publication date: June 2019Source: Materials Science and Engineering: C, Volume 99Author(s): Deepak Patil, Mishi Kaushal Wasson, S. Aravindan, P. Vivekanandan, P.V. RaoAbstractSilver coating of different thicknesses ranging from 5 to 20 nm was deposited on the Ti6Al4V substrate using DC sputtering followed by thermal annealing at 750 °C for 15 min in an ambient environment. The surface topography and elemental composition of annealed samples were analyzed using different characterization techniques. The silver ions (Ag+) concentration released from the modified titanium surface was calculated through inductive co...

Garcia, Gye Hwa Shin, Jun Tae KimAbstractHydroxypropyl methylcellulose (HPMC) was combined with oregano essential oil nanoemulsion (ORNE) at concentrations of 0–7.5% (v/v) to produce active composite films. The mechanical, optical, water vapour barrier, antimicrobial, and antioxidant properties of the composite films were evaluated. The composite films containing 5.0% (v/v) ORNE showed increased elongation at break compared to the control films, although their tensile strength and Young's modulus were lower. In addition,...

Type 1 fimbriae are proteinaceous filamentous structures present on bacterial surfaces and are mainly composed of the major fimbrial protein subunit FimA and the adhesive protein FimH, which is located at the tip of the fimbrial shaft. Here, we investigated the involvement of type 1 fimbriae in the expression of proinflammatory cytokines in macrophages infected with Salmonella enterica serovar Typhimurium. The level of interleukin-1β (IL-1β) mRNA was lower in macrophages infected with fimA or fimH mutant strains than in those infected with wild-type Salmonella. Treatment of macrophages with purified recombinant F...

In this study, effects of NaCl on heat resistance of Salmonella Typhimurium were investigated. After cultivation in TSB containing 0.5% (TSB), 4% (4SC) and 8% (8SC) NaCl, S. Typhimurium cells were heated at 60 °C for 20 min. Total viable counts including intact cells and injured but recoverable cells determined by the plating method using TSA of S. Typhimurium cultured in 4SC and 8SC were significantly higher than those of the cells cultured in TSB. Meanwhile, changes of gene transcription were analyzed by DNA microarray. Transcription of genes involved in the colanic acid synthesis largely increased after cultivat...

In this study, the effect of cathelicidin in the maintenance of epithelial integrity, Toll-like receptor recognition, bacterial invasion and initiation of inflammatory response againstSalmonella typhimurium is investigated in cultured human colonic epithelium. We found exogenous human cathelicidin restores the epithelial integrity inS. typhimurium-infected colonic epithelial (T84) cells by mostly post-translational effects associated with reorganization of zonula occludens (ZO)-1 tight junction proteins. Endogenous cathelicidin preventsS. typhimurium internalization as shown in colonic epithelial cells genetically deficien...
