Thus, we identify IRF5 as a key transcriptional regulator of the colonic MNP system during intestinal inflammation.In the developing countries, Shigella flexneri is the most common enteric pathogen causing bacillary dysentery. And the biofilm formation of S. flexneri can cause the emergence of antibiotic-resistant strains and serious threat to food safety and human health. In this study, the effects of Lactobacillus plantarum-12 exopolysaccharides (L-EPS) and S. flexneri exopolysaccharides (S-EPS) on the S. flexneri CMCC51574 biofilm formation were investigated. The results showed that L-EPS could decrease the polysaccharides production in the extracellular polymeric matrix of S. flexneri, and inhibit the biofilm formation of S. flexneri L-EPS could decrease the minimum biofilm elimination concentration (MBEC) of the antibiotics against S. flexneri biofilm and inhibit S. flexneri adhesion and invasion to the HT-29 cell monolayers, which might be ascribed to the S. flexneri biofilm disturbance by L-EPS. While the S-EPS exhibited the exactly opposite effects compared to L-EPS. The monosaccharide composition analysis showed e biofilm formation, adhesion and invasion to HT-29 cells of S. flexneri And the L-EPS could also decrease the minimum biofilm elimination concentration (MBEC) of the antibiotics against S. flexneri biofilm. Therefore, the L-EPS was a bioactive macromolecule with the potential ability against the infections of the S. flexneri.The Polio Endgame Strategy 2019-2023 has been developed. However, more effective and efficient surveillance activities should be conducted with the preparedness of emergence for vaccine-derived poliovirus (VDPV) or wild poliovirus (WPV). NCT-503 clinical trial We reviewed the impact of the case-based acute flaccid paralysis (AFP) surveillance (1991-2018) and environmental surveillance (2011-2018) in polio eradication in Shandong province of China. Clinical characteristics of AFP cases and enterovirus (EV) investigation of research samples were assessed. During the period, 10224 AFP cases were investigated and 352 sewage samples were collected. The non-polio AFP rate sustained at over 2.0/100,000 since 1997. Of 10224 cases, males and young children experienced higher risk of severe diseases, and 68.5% suffered lower limb paralysis. We collected 1707 EVs from AFP cases, including 763 polioviruses and 944 non-polio enteroviruses (NPEVs). No WPV was isolated since 1992. The AFP surveillance showed high sensitivity in detecting 143 vaccsurveillance and 8-year environmental surveillance, provides continued high quality surveillance performance in achieving the GPEI and detecting the circulation of enterovirus. Given the ongoing cVDPV outbreaks in the world, we present the surveillance capacity of environmental surveillance in capturing enterovirus circulation. The finally poliovirus (especially VDPV) elimination has become increasingly complex, and the case-based AFP surveillance alone will lead to difficulties in early detecting dynamics of poliovirus transmission and monitoring the extent of environmental circulation. This study goes beyond previous work to provide a detailed comprehensive evaluation of the enterovirus surveillance and can be used to formulate a set of implementation plan and performance indicators for environmental surveillance.A cAMP receptor protein (CRPVH2) was detected as global regulator in Gordonia polyisoprenivorans VH2 and was supposed to participate in the network regulating poly(cis-1,4-isoprene) degradation as novel key regulator. CRPVH2 shares a sequence identity of 79 % with GlxR, a well-studied global regulator of Corynebacterium glutamicum Furthermore, CRPVH2 and GlxR have a common oligomerization state, similar binding motifs and thus most likely similar functions as global regulators. Size exclusion chromatography of purified CRPVH2 confirmed the existence as a homodimer with a native molecular weight of 44.1 kDa in the presence of cAMP. It bound to the TGTGAN6TCACT motif within the 131 bp intergenic region of divergently oriented lcp1 VH2 and lcpR VH2, encoding a latex clearing protein and its putative repressor, respectively. DNase I footprinting assays revealed the exact operator size of CRPVH2 in the intergenic region (25 bp), that partly overlapped with the proposed promoters of lcpR VH2 and lcp1 VH2 Our findindegradation pathway, that seems to be upregulated in the presence of the polymer. We identified a novel key regulator of rubber degradation (CRPVH2) that regulates several parts of the pathway in the potent rubber-degrader G. polyisoprenivorans VH2. Furthermore, we provide evidence for a widespread involvement of CRP regulators in the degradation of rubber in various other rubber-degrading actinomycetes. Thus, the novel insights into the regulation of rubber degradation are essential for developing efficient microbial degradation strategies of the rubber waste materials by the group of actinomycetes.Over a 2-year period, drag swabs of orchard soil surface, and air, soil, and almond leaf samples were collected in an almond orchard adjacent to (35 m from first row of trees) and downwind from a poultry operation, and in two almond orchards (controls) that were surrounded by other orchards. Samples were evaluated for aerobic plate count, generic Escherichia coli, other coliforms, presence of Salmonella, bacterial community analysis through sequencing of the 16s rRNA gene, and amounts of dry solids (dust) on leaf surfaces on trees 0, 60, and 120 m into each orchard. E. coli was isolated from 41 of 206 (20%) and one of 207 (0.48%) air samples in the almond-poultry and control orchards, respectively. Salmonella was not isolated from any of the 529 samples evaluated. On average, the amount of dry solids on leaves collected from trees closest to the poultry operation was more than two-fold greater than from trees 120 m into the orchard or from any of the trees in the control orchards. Members of the family Staphylococcaceae-often associated with poultry-were, on average, significantly (p less then 0.001) more abundant in the phyllosphere of trees closest to the poultry operation (10% of relative abundance) than in trees 120 m into the orchard (1.7% of relative abundance) or from any of the trees in control orchards (0.41% of relative abundance). Poultry-associated microorganisms from a commercial operation transferred a short distance into an adjacent downwind almond orchard.IMPORTANCE The movement of microorganisms, including foodborne pathogens, from animal operations into adjacent plant crop-growing environments is not well characterized. This study provides evidence that dust and bioaerosols moved from a commercial poultry operation a short distance downwind into an almond orchard and altered the microbiome recovered from the leaves. These data provide growers with information they can use to assess food safety risks on their property.
