prevalence of genes encoding the type three secretion system and the effectors aext and aexu in the aeromonas veronii group.the prevalence of important virulence factors, the type iii secretion system (t3ss) and two t3ss-dependent toxins, aext and aexu, was evaluated in the aeromonas veronii group (avg). members of the avg have a broad host range, including vertebrates and invertebrates, and form a variety of associations, spanning from pathogenic to mutualistic. our avg strain collection consists of human, duck, eel, and leech isolates. these isolates were examined for the presence of the t3ss, aext, and aexu throug ...200919534604
tri-trophic linkages in disease: pathogen transmission to rainbow trout through stonefly prey.relationships between macroinvertebrates and microorganisms in aquatic environments are only poorly understood despite the fact that many aquatic macroinvertebrates feed on microbial biofilms during some life stage. better understanding of trophic interactions between microbial biofilms, macroinvertebrates, and fish may also help control fish diseases and loss of natural resources. it has also been suggested that pollution, habitat fragmentation, and poor water quality may contribute to increase ...200919689880
characterization of electrochemical activity of a strain iso2-3 phylogenetically related to aeromonas sp. isolated from a glucose-fed microbial fuel cell.the microbial communities associated with electrodes in closed and open circuit microbial fuel cells (mfcs) fed with glucose were analyzed by 16s rrna approach and compared. the comparison revealed that bacteria affiliated with the aeromonas sp. within the gammaproteobacteria constituted the major population in the closed circuit mfc (harvesting electricity) and considered to play important roles in current generation. we, therefore, attempted to isolate the dominant bacteria from the anode biof ...200919575435

biopreservation of refrigerated and vacuum-packed dicentrarchus labrax by lactic acid bacteria.two lactic acid bacteria (lab) were selected from 100 lab isolated from various sea products to examine their use in dicentrarchus labrax preservation. the isolates, tentatively named strain nr 3 and 7, were identified as lactobacillus plantarum and l. pentosus, respectively. they showed antagonistic activity against psychrotroph, pathogenic, and coliform bacteria. the antagonistic activity of strain 3 was suggested to be by bacteriocins since activity was abolished by protease treatment, while ...200919723220
inhibition of frog antimicrobial peptides by extracellular products of the bacterial pathogen aeromonas hydrophila.to determine whether the extracellular products (ecps) from aeromonas hydrophila, a frog bacterial pathogen that is resistant to skin antimicrobial peptides of three different frog species xenopus laevis, litoria aurea and litoria raniformis, can modulate the activity of these peptides.200919728406
n-acylhomoserine lactones involved in quorum sensing control the type vi secretion system, biofilm formation, protease production, and in vivo virulence in a clinical isolate of aeromonas hydrophila.in this study, we delineated the role of n-acylhomoserine lactone(s) (ahls)-mediated quorum sensing (qs) in the virulence of diarrhoeal isolate ssu of aeromonas hydrophila by generating a double knockout delta ahyri mutant. protease production was substantially reduced in the delta ahyri mutant when compared with that in the wild-type (wt) strain. importantly, based on western blot analysis, the delta ahyri mutant was unable to secrete type vi secretion system (t6ss)-associated effectors, namely ...200919729404
dietary mannan oligosaccharide supplementation modulates intestinal microbial ecology and improves gut morphology of rainbow trout, oncorhynchus mykiss (walbaum).a study was conducted to investigate the effect of mannan oligosaccharide (mos) on the gut microbiota and intestinal morphology of rainbow trout under commercial farming conditions. juvenile (mean initial bw 38.2 +/- 1.7 g) and subadult (111.7 +/- 11.6 g) trout were fed 2 dietary treatments for 111 and 58 d, respectively. the control treatment consisted of a standard commercial diet, and the mos treatment consisted of the control diet supplemented with 0.2% mos. morphology of the anterior and th ...200919617514

divergent evolution and purifying selection of the flaa gene sequences in aeromonas.the bacterial flagellum is the most important organelle of motility in bacteria and plays a key role in many bacterial lifestyles, including virulence. the flagellum also provides a paradigm of how hierarchical gene regulation, intricate protein-protein interactions and controlled protein secretion can result in the assembly of a complex multi-protein structure tightly orchestrated in time and space. as if to stress its importance, plants and animals produce receptors specifically dedicated to t ...200919622168
inhibition of gamma-thrombin-induced human platelet aggregation by histone h1subtypes and h1.3 fragments.human platelets are differentially activated by varying concentrations of alpha-thrombin or by beta- and gamma-thrombin via three thrombin receptors, par-1, par-4 and gpibalpha.it is likely that the development of a normal or abnormal hemostatic event in humans is dictated, in part, by the selective activation of these receptors. the ability to differentially inhibit these thrombin receptors could, therefore, have clinical significance. we have previously demonstrated that histone h1 selectively ...200919637099
integration of microfiltration and anion-exchange nanoparticles-based magnetic separation with maldi mass spectrometry for bacterial analysis.matrix-assisted laser desorption ionization mass spectrometry (maldi-ms) is powerful in characterizing and identifying bacterial isolates. however, sufficient quantities of bacterial cells are required for generating maldi mass spectra and a procedure to isolate and enrich target bacteria from sample matrix prior to maldi-ms analysis is often necessary. in this paper, anion-exchange superparamagnetic nanoparticles (nps), i.e., fluidmag-deae and fluidmag-q, were employed to capture aeromonas, sal ...200919782231
a bifunctional enzyme in a single gene catalyzes the incorporation of glcn into the aeromonas core lipopolysaccharide.the core lipopolysaccharide (lps) of aeromonas hydrophila ah-3 and aeromonas salmonicida a450 is characterized by the presence of the pentasaccharide alpha-d-glcn-(1-->7)-l-alpha-d-hep-(1-->2)-l-alpha-d-hep-(1-->3)-l-alpha-d-hep-(1-->5)-alpha-kdo. previously it has been suggested that the waha protein is involved in the incorporation of glcn residue to outer core lps. the waha protein contains two domains: a glycosyltransferase and a carbohydrate esterase. in this work we demonstrate that the in ...200919805547
mutations in the aeromonas salmonicida subsp. salmonicida type iii secretion system affect atlantic salmon leucocyte activation and downstream immune responses.deletion mutants of aeromonas salmonicida subsp. salmonicida were used to determine the effect of the type three secretion system (ttss) on atlantic salmon anterior head kidney leucocytes (ahkl). one strain had a deletion in the outer membrane pore gene, ascc; and the other in three effector genes: aopo, aoph and aext (we call this strain deltaaop3). host cell invasion success and 24h survival were depressed in deltaascc, as was 24h survival of deltaaop3, when compared to the wild type strain. c ...200919751835
a novel method for the diagnosis of drowning by detection of aeromonas sobria with pcr method.the acid digestion method has been widely used for the diagnosis of death by drowning, but it is not always sensitive. however, there has been no definitive method to replace acid digestion until now. we speculate that bacteria are more useful markers than plankton for the diagnosis of death by drowning. in this study, from the preserved blood samples of 32 freshwater drowning cases, specific dna fragments of aeromonas sobria, one of the most common aquatic bacteria, were examined using pcr. the ...200919766051

inhibition by chestnut honey of n-acyl-l-homoserine lactones and biofilm formation in erwinia carotovora, yersinia enterocolitica, and aeromonas hydrophila.bacteria are able to communicate and coordinate certain processes using small secreted signaling molecules called autoinducers. this phenomenon, known as "quorum sensing" (qs), may be essential for the synchronization of virulence factors as well as biofilm development. the interruption of bacterial qs is acknowledged to attenuate virulence and considered to be a potential new therapy to treat infections caused by pathogenic bacteria. n-acyl-l-homoserine lactones (ahls) have been identified as t ...200919950997
