Such medicinal leeching, an ancient medical practice, is still being used in microsurgery and the treatment of venous congestion or occlusion.Diarrhea: An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.Virulence: The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenic capacity of an organism is determined by its VIRULENCE FACTORS.Catfishes: Common name of the order Siluriformes.

The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.Microscopy, Electron, Scanning: Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.Fimbriae, Bacterial: Thin, hairlike appendages, 1 to 20 microns in length and often occurring in large numbers, present on the cells of gram-negative bacteria, particularly Enterobacteriaceae and Neisseria. Unlike flagella, they do not possess motility, but being protein (pilin) in nature, they possess antigenic and hemagglutinating properties. They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (ADHESINS, BACTERIAL). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of "pili", which is confined to sex pili (PILI, SEX).Deferoxamine: Natural product isolated from Streptomyces pilosus.

Quorum sensing-dependent regulation and blockade of exoprotease production in Aeromonas hydrophila. (1/265)

In Aeromonas hydrophila, the ahyI gene encodes a protein responsible for the synthesis of the quorum sensing signal N-butanoyl-L-homoserine lactone (C4-HSL). Inactivation of the ahyI gene on the A. hydrophila chromosome abolishes C4-HSL production. The exoprotease activity of A. hydrophila consists of both serine protease and metalloprotease activities; in the ahyI-negative strain, both are substantially reduced but can be restored by the addition of exogenous C4-HSL. In contrast, mutation of the LuxR homolog AhyR results in the loss of both exoprotease activities, which cannot be restored by exogenous C4-HSL. Furthermore, a substantial reduction in the production of exoprotease by the ahyI+ parent strain is obtained by the addition of N-acylhomoserine lactone analogs that have acyl side chains of 10, 12, or 14 carbons. The inclusion of N-(3-oxododecanoyl)-L-homoserine lactone or N-(3-oxotetradecanoyl)-L-homoserine lactone at 10 microM in overnight cultures of A. hydrophila abolishes exoprotease production in azocasein assays and reduces the activity of all the exoprotease species seen in zymograms.  (+info)

Kinetic and spectroscopic characterization of native and metal-substituted beta-lactamase from Aeromonas hydrophila AE036. (2/265)

Two metal ion binding sites are conserved in metallo-beta-lactamase from Aeromonas hydrophila. The ligands of a first zinc ion bound with picomolar dissociation constant were identified by EXAFS spectroscopy as one Cys, two His and one additional N/O donor. Sulfur-to-metal charge transfer bands are observed for all mono- and di-metal species substituted with Cu(II) or Co(II) due to ligation of the single conserved cysteine residue. Binding of a second metal ion results in non-competitive inhibition which might be explained by an alternative kinetic mechanism. A possible partition of metal ions between the two binding sites is discussed.  (+info)

Cloning, sequencing, and role in serum susceptibility of porin II from mesophilic Aeromonas hydrophila. (3/265)

We cloned and sequenced the structural gene for Aeromonas hydrophila porin II from strain AH-3 (serogroup O:34). The genetic position of this gene, like that of ompF in Escherichia coli, is adjacent to aspC and transcribed in the same direction. However, upstream of the porin II gene no similarities with E. coli were found. We obtained defined insertion mutants in porin II gene either in A. hydrophila (O:34) or A. veronii sobria (serogroup O:11) serum-resistant or -sensitive strains. Furthermore, we complemented these mutants with a plasmid harboring only the porin II gene, which allowed us to define the role of porin II as an important surface molecule involved in serum susceptibility and C1q binding in these strains.  (+info)

The cytotoxic enterotoxin of Aeromonas hydrophila induces proinflammatory cytokine production and activates arachidonic acid metabolism in macrophages. (4/265)

An aerolysin-related cytotoxic enterotoxin (Act) of Aeromonas hydrophila possesses multiple biological activities, which include its ability to lyse red blood cells, destroy tissue culture cell lines, evoke a fluid secretory response in ligated intestinal loop models, and induce lethality in mice. The role of Act in the virulence of the organism has been demonstrated. In this study, we evaluated the potential of Act to induce production of proinflammatory cytokines associated with Act-induced tissue injury and Act's capacity to activate in macrophages arachidonic acid (AA) metabolism that leads to production of eicosanoids (e.g., prostaglandin E(2) [PGE(2)]). Our data indicated that Act stimulated the production of tumor necrosis factor alpha and upregulated the expression of genes encoding interleukin-1beta (IL-1beta) and IL-6 in the murine macrophage cell line RAW264.7. Act also activated transcription of the gene encoding inducible nitric oxide synthase. Act evoked the production of PGE(2) coupled to the cyclooxygenase-2 (COX-2) pathway. AA is a substrate for PGE(2), and Act produced AA from phospholipids by inducing group V secretory phospholipase A(2). We also demonstrated that Act increased cyclic AMP (cAMP) production in macrophages. cAMP, along with PGE(2), could potentiate fluid secretion in animal models because of infiltration and activation of macrophages resulting from Act-induced tissue injury. After Act treatment of RAW cells, we detected an increased translocation of NF-kappaB and cAMP-responsive element binding protein (CREB) to the nucleus using gel shift assays. Act also upregulated production of antiapoptotic protein Bcl-2 in macrophages, suggesting a protective role for Bcl-2 against cell death induced by proinflammatory cytokines. The increased expression of genes encoding the proinflammatory cytokines, COX-2, and Bcl-2 appeared correlated with the activation of NF-kappaB and CREB. This is the first report of the detailed mechanisms of action of Act from A. hydrophila.  (+info)

Molecular analysis of genetic differences between virulent and avirulent strains of Aeromonas hydrophila isolated from diseased fish. (5/265)

Aeromonas hydrophila, a normal inhabitant of aquatic environments, is an opportunistic pathogen of a variety of aquatic and terrestrial animals, including humans. A. hydrophila PPD134/91 is defined as virulent whereas PPD35/85 is defined as avirulent on the basis of their different LD50 values in fish. Suppression subtractive hybridization (SSH) was used to identify genetic differences between these two strains. Sixty-nine genomic regions of differences were absent in PPD35/85, and the DNA sequences of these regions were determined. Sixteen ORFs encoded by 23 fragments showed high homology to known proteins of other bacteria. ORFs encoded by the remaining 46 fragments were identified as new proteins of A. hydrophila, showing no significant homology to any known proteins. Among these PPD134/91-specific genes, 22 DNA fragments (21 ORFs) were present in most of the eight virulent strains studied but mostly absent in the seven avirulent strains, suggesting that they are universal virulence genes in A. hydrophila. The PPD134/91-specific genes included five known virulence factors of A. hydrophila: haemolysin (hlyA), protease (oligopeptidase A), outer-membrane protein (Omp), multidrug-resistance protein and histone-like protein (HU-2). Another 47 DNA fragments (44 ORFs) were mainly present in PPD134/91, indicating the heterogeneity among motile aeromonads. Some of these fragments encoded virulence determinants. These included genes for the synthesis of O-antigen and type II restriction/modification system. The results indicated that SSH is successful in identifying genetic differences and virulence genes among different strains of A. hydrophila.  (+info)

A major secreted elastase is essential for pathogenicity of Aeromonas hydrophila. (6/265)

Aeromonas hydrophila is an opportunistic pathogen and the leading cause of fatal hemorrhagic septicemia in rainbow trout. A gene encoding an elastolytic activity, ahyB, was cloned from Aeromonas hydrophila AG2 into pUC18 and expressed in Escherichia coli and in the nonproteolytic species Aeromonas salmonicida subsp. masoucida. Nucleotide sequence analysis of the ahyB gene revealed an open reading frame of 1,764 nucleotides with coding capacity for a 588-amino-acid protein with a molecular weight of 62,728. The first 13 N-terminal amino acids of the purified protease completely match those deduced from DNA sequence starting at AAG (Lys-184). This finding indicated that AhyB is synthesized as a preproprotein with a 19-amino-acid signal peptide, a 164-amino-acid N-terminal propeptide, and a 405-amino-acid intermediate which is further processed into a mature protease and a C-terminal propeptide. The protease hydrolyzed casein and elastin and showed a high sequence similarity to other metalloproteases, especially with the mature form of the Pseudomonas aeruginosa elastase (52% identity), Helicobacter pylori zinc metalloprotease (61% identity), or proteases from several species of Vibrio (52 to 53% identity). The gene ahyB was insertionally inactivated, and the construct was used to create an isogenic ahyB mutant of A. hydrophila. These first reports of a defined mutation in an extracellular protease of A. hydrophila demonstrate an important role in pathogenesis.  (+info)

Microbial iron transport via a siderophore shuttle: a membrane ion transport paradigm. (7/265)

A mechanism of ion transport across membranes is reported. Microbial transport of Fe(3+) generally delivers iron, a growth-limiting nutrient, to cells via highly specific siderophore-mediated transport systems. In contrast, iron transport in the fresh water bacterium Aeromonas hydrophila is found to occur by means of an indiscriminant siderophore transport system composed of a single multifunctional receptor. It is shown that (i) the siderophore and Fe(3+) enter the bacterium together, (ii) a ligand exchange step occurs in the course of the transport, and (iii) a redox process is not involved in iron exchange. To the best of our knowledge, there have been no other reports of a ligand exchange mechanism in bacterial iron transport. The ligand exchange step occurs at the cell surface and involves the exchange of iron from a ferric siderophore to an iron-free siderophore already bound to the receptor. This ligand exchange mechanism is also found in Escherichia coli and seems likely to be widely distributed among microorganisms.  (+info)

Prevalence of enterotoxin genes in Aeromonas spp. isolated from children with diarrhea, healthy controls, and the environment. (8/265)

Aeromonads are causative agents of a number of human infections. Even though aeromonads have been isolated from patients suffering from diarrhea, their etiological role in gastroenteritis is unclear. In spite of a number of virulence factors produced by Aeromonas species, their association with diarrhea has not been clearly linked. Recently, we have characterized a heat-labile cytotonic enterotoxin (Alt), a heat-stable cytotonic enterotoxin (Ast), and a cytotoxic enterotoxin (Act) from a diarrheal isolate of Aeromonas hydrophila. Alt and Ast are novel enterotoxins which are not related to cholera toxin; Act is aerolysin related and has hemolytic, cytotoxic, and enterotoxic activities. We studied the distribution of the alt, ast, and act enterotoxin genes in 115 of 125 aeromonads isolated from 1, 735 children with diarrhea, in all 27 aeromonads isolated from 830 control children (P = 7 x 10(-4) for comparison of rates of isolation of aeromonads from cases versus those from controls), and in 120 randomly selected aeromonads from different components of surface water in Bangladesh. Aeromonas isolates which were positive only for the presence of the alt gene had similar distributions in the three sources; the number of isolates positive only for the presence of the ast gene was significantly higher for the environmental samples than for samples from diarrheal children; and isolates positive only for the presence of the act gene were not found in any of the three sources. Importantly, the number of isolates positive for both the alt and ast genes was significantly higher for diarrheal children than for control children and the environment. Thus, this is the first study to indicate that the products of both the alt and ast genes may synergistically act to induce severe diarrhea. In 26 patients, Aeromonas spp. were isolated as the sole enteropathogen. Analysis of clinical data from 11 of these patients suggested that isolates positive for both the alt and ast genes were associated with watery diarrhea but that isolates positive only for the alt gene were associated with loose stools. Most of the isolates from the three sources could be classified into seven phenospecies and eight hybridization groups. For the first time, Aeromonas eucrenophila was isolated from two children, one with diarrhea and another without diarrhea.  (+info)

The genetic organization and sequences of the group II capsule gene cluster of Aeromonas hydrophila PPD134/91 have been determined previously. The purified capsular polysaccharides can increase the ability of avirulent strain PPD35/85 to survive in naive tilapia serum but have no inhibitory effect on the adhesion of PPD134/91 to carp epithelial cells. In this study, the presence of group II capsules among 33 randomly chosen A. hydrophila strains was examined by electron microscopy and genetic analysis. Ten strains were found to produce group II capsules. A PCR detection system was developed to identify two types of group II capsules (IIA and IIB) based on their genetic organization in the region II gene clusters. Group IIA capsules in the authors' collection of A. hydrophila strains are mainly found in the O : 18 and O : 34 serogroups, while group IIB capsules are found in the O : 21 and O : 27 serogroups. The presence of group II capsules in A. hydrophila strongly correlates with the serum and
Aeromonas hydrophila. Coloured transmission electron micrograph of thin-sectioned cells of Aeromonas hydrophila bacteria. It is a Gram- negative, rod-shaped bacillus. Aeromonas hydrophila is associated with septicaemia, pneumonia and gastroenteritis in humans. In particular it causes opportunistic infections in patients with lowered immunity, such as in cancer and liver disease. Aeromonas hydrophila has been isolated from urine, sputum, faeces and bile. It is resistant to many types of antibiotic including penicillin, but can be controlled with tetracyclins and gentamicin. Magnification: x28,800 at 6x4.5cm size. - Stock Image B220/0809
Aeromonas hydrophila is a gram-negative bacteria that causes motile Aeromonas septicemia (MAS) in many fish species. Typically, A. hydrophila is considered an opportunistic pathogen; however, an emergent strain which is especially deadly to commercially farmed catfish has become a major concern for the catfish industry since 2009. Catfish production is the top aquaculture industry in the United States, and the second largest producer is the state of Alabama. The emergent strain of A. hydrophila affects larger fish, which means that the fish are lost at market size. This results in enormous financial losses for farmers. The strain is especially prevalent in East Mississippi and West Alabama, which are two of the largest areas for catfish production ...
The freshwater crayfish, Pacifastacus leniusculus, mounts a strong innate immune response against microbes such as viruses and bacteria. In this thesis, a novel RNA interference (RNAi) method mediated with histone H2A was developed and applied in crayfish hematopoietic tissue cell cultures for gene functional studies. Further, the interactions between host (crayfish) and pathogens (white spot syndrome virus and Aeromonas hydrophila, respectively) were studied using RNAi technology in live animals. An antilipopolysaccharide factor isolated from viral challenged crayfish by suppression subtractive hybridization was shown to interfere with the propagation of white spot syndrome virus both in vivo and in vitro in crayfish, suggesting an important role of this factor in antiviral defense. Besides, RNAi of phenoloxidase, a critical immune effector involved in melanization, revealed that phenoloxidase activity is necessary for crayfish immune defense against a highly pathogenic bacterial infection in ...
Ultrastructural studies of Aeromonas hydrophila strain AH26 revealed two distinctive pilus types: "straight" pili appear as brittle, rod-like filaments, whereas "flexible" pili are supple and curvilinear. Straight pili are produced constitutively under all tested conditions of growth. In contrast, the expression of flexible pili is regulated by physical and chemical variables, being produced at 22 vs. 37 degrees C, in a liquid vs. a solid medium, and when the availability of free-iron is reduced by the presence of deferoxamine mesylate. Both pilus proteins were purified and biochemically and functionally characterized. The major repeating subunit of the straight pilus is a 17,000-mol wt polypeptide with amino acid sequence homology with Escherichia coli type 1 and Pap pili. The flexible pilus filament is a homopolymer composed of a novel 46 amino acid polypeptide. Resistance of the flexible pilus filament to disaggregation using various chemical treatments was demonstrated; its stability as a ...

Introduction: Aeromonas hydrophila is implicated in a wide spectrum of skin and soft‐tissue infections, ranging from cellulitis to life‐threatening necrotizing fasciitis and myonecrosis. Most reported cases of fulminant A. hydrophila necrotizing soft‐tissue infections occur following a history of trauma sustained in an aquatic environment. However, fatal Aeromonas myonecrosis and gas gangrene without antecedent trauma, underlying liver disease, malignancy or immunosuppression has rarely been reported in the literature. Case presentation: A 50‐year‐old woman who underwent elective percutaneous transluminal coronary angioplasty became acutely ill with septic shock and adult respiratory distress syndrome, on post‐operative day 3. She developed severe oedema, blistering and gangrenous patches in the right lower limb. She died on post‐operative day 3 despite intensive care. A. hydrophila was cultured from the blister fluid, two blood cultures and tissue. An inspection of the hospital water
Certain strains of Aeromonas hydrophila are oxidase negative when grown on gram-negative selective and differential media. Of 100 strains of A. hydrophila examined, 8 were found to possess this characteristic. Information is provided on how to detect these common variants of A. hydrophila.
A technique for rapid detection of pathogenic microorganisms is essential for the diagnosis of associated infections and for food safety analysis. Aeromonas hydrophila is one such food contaminant. Several methods for rapid detection of this pathogen have been developed; these include multiplex polymerase chain reaction assays and the colony overlay procedure for peptidases. However, these conventional methods can only be used to detect the microorganisms at high accuracy after symptomatic onset of the disease. Therefore, in the future, simple pre-screening methods may be useful for preventing food poisoning and disease. In this paper, we present a novel system for the rapid detection of the microorganism A. hydrophila in cultured media (in <2 h), with the use of an electronic nose (FF-2A). With this electronic nose, we detected the changes of volatile patterns produced by A. hydrophila after 30 min culture. Our calculations revealed that the increased volatiles were similar to the odours of organic

Aerolysin is a major virulence factor produced by the Gram-negative bacterium Aeromonas hydrophila and is a member of the beta-pore-forming toxin family. Two oligomerization-deficient aerolysin mutants, H132D and H132N, have been overproduced, proteolyzed by trypsin digestion and purified. Crystals were grown from the proteolyzed forms and diffraction data were collected for the two mutants to 2.1 and 2.3 A resolution, respectively. The prism-shaped crystals belonged to space group C2. The crystal structure of the mutants in the mature, but not heptameric, aerolysin form will provide insight into the intermediate states in the oligomerization process of a pore-forming toxin..

1. An enzyme produced by Aeromonas hydrophila and capable of lysing Staphylococcus aureus cells was purified 180-fold by gel filtration and chromatography on columns of AG-50 W resin. 2. Physical measurements on the purified enzyme suggest that it is a small basic protein with an isoelectric point between pH9·0 and pH9·5. 3. Maximum lytic activity was obtained in 20mm-tris-glycine buffer, pH8·5, at 45°, with no detectable activity in the absence of a nitrogenous base. 4. The enzyme is active in the above buffer containing 1·5m-sucrose, and is useful for the preparation of protoplasts of Staphylococcus aureus. 5. Purified cell wall peptidoglycans of two strains of Staphylococcus aureus, differing in amino acid composition, were hydrolysed by the enzyme with the liberation of glycine oligopeptides, principally diglycine and triglycine. 6. Synthetic glycine oligopeptides larger than triglycine, but not polyglycine, were hydrolysed, as were a number of leucine-containing dipeptides and ...

Forty strains of Aeromonas hydrophila and Aeromonas veronii recovered from invasive and non-invasive infections were tested for their susceptibility to complement-mediated lysis by 65% pooled human serum (PHS). Based upon the results of this assay, two major populations could be defined. The first group (n = 20) consisted of serogroup 0:11 strains, all of which possessed a paracrystalline surface layer (S layer); all of these strains were refractory to the bactericidal activity of 65% PHS with the exception of A. hydrophila strain AH-121, which was composed of mixed subpopulations of serum-susceptible and serum-resistant clones. A second collection of isolates (n = 20), all of which were S-layer-negative, contained a subgroup of strains (n = 7) that were highly susceptible to complement-mediated lysis, showing a greater than 100-fold reduction of viable progeny within 30 min of exposure to 65% PHS. Serum-resistant strains from both groups could not be lysed by exposure of bacterial cells to polyclonal

Climate change may cause increased microbial growth in water sources and more knowledge is required on how this may affect the hygienic water quality, i.e., whether increased occurrence of cyanobacteria and algae may stimulate the growth rate of opportunistic pathogenic bacteria. Laboratory experiments were performed to investigate if the presence of the cyanobacteria Anabanea lemmermannii and Microcystis aeruginosa affected the survival and growth rate of the opportunistic pathogenic bacteria Aeromonas hydrophila and Pseudomonas aeruginosa, and the faecal indicators Escherichia coli and coliforms. Cyanobacteria were cultured in bottles containing the nutrient-poor medium O2. Sewage, A. hydrophila or P. aeruginosa was added to cyanobacterial cultures and the bacterial growth and survival was followed. E. coli and coliforms from sewage died within few days and the decay rate was not affected by the presence of cyanobacteria. The presence of Anabaena stimulated the growth rate of P. aeruginosa, ...
January 25, 2016. Scientists recently discovered different strains of deadly flesh-eating bacteria working together to spread infection and they now have a better understanding of the role of the toxins they produce. The discovery could change how the illness and other diseases are treated.. The study, published in Proceedings of the National Academy of Sciences, was conducted by Ashok Chopra, professor of microbiology and immunology at the University of Texas Medical Branch at Galveston in partnership with the Federal Drug Administration, CosmosID Inc., the University of Maryland and the Johns Hopkins University. The findings are considered a positive step towards development of life-saving therapeutics to treat patients.. The bacteria Aeromonas hydrophila has been increasingly acknowledged as being responsible for necrotizing fasciitis, a rapidly-progressing skin and muscle tissue infection. The microbe is commonly found in fresh and brackish water, especially during warmer months. The ...

Aeromonas hydrophila is a Gram-negative opportunistic pathogen of fish and terrestrial animals. In humans, A. hydrophila mainly causes gastroenteritis, septicaemia and tissue infections. The mechanisms of infection, the main virulence factors and the host immune response triggered by A. hydrophila have been studied in detail using murine models and adult fish. However, the great limitation of studying adult animals is that the animal must be sacrificed and its tissues/organs extracted, which prevents the study of the infectious processes in the whole living animal.Zebrafish larvae are being used for the analysis of several infectious diseases, but their use for studying the pathogenesis of A. hydrophila has never been explored. The great advantage of zebrafish larvae is their transparency during the first week after fertilization, which allows detailed descriptions of the infectious processes using in vivo imaging techniques such as differential interferential contrast (DIC) and fluorescence microscopy.

Chemical analyses and mass spectrometry were used to study the structure of the lipopolysaccharide (LPS) isolated from Aeromonas bestiarum strain K296, serotype O18. ESI-MS revealed that the most abundant A. bestiarum LPS glycoforms have a hexa-acylated or tetra-acylated lipid A with conserved architecture of the backbone, consisting of a 1,4′-bisphosphorylated β-(1→6)-linked d-GlcN disaccharide with an AraN residue as a non-stoichiometric substituent and a core oligosaccharide composed of Kdo1Hep6Hex1HexN1P1. 1D and 2D NMR spectroscopy revealed that the O-specific polysaccharide (OPS) of A. bestiarum K296 consists of a branched tetrasaccharide repeating unit containing two 6-deoxy-l-talose (6dTalp), one Manp and one GalpNAc residues; thus, it is similar to that of the OPS of A. hydrophila AH-3 (serotype O34) in both the sugar composition and the glycosylation pattern. Moreover, 3-substituted 6dTalp was 2-O-acetylated and additional O-acetyl groups were identified at O-2 and O-4 (or O-3) positions
Aeromonas is a Gram-negative bacillus, widely found in aquatic environment. Osteoarticular pathology caused by Aeromonas hydrophila is rarely encountered. To the best of our knowledge, this is the first case of chronic osteomyelitis by A. hydrophila reported from India. We report a case of chronic osteomyelitis of the lower limb due to A. hydrophila, which occurred as a delayed complication following open reduction and internal fixation. Prompt medical and surgical intervention supplemented by a comprehensive microbiological workup aided in pathogen identification and specific antimicrobial administration resulting in the successful outcome of our patient ...
A. hydrophila represents a group of bacteria pathogenic to fish. Recently the same bacteria have been increasingly implicated in human infections, particularly as a secondary invader, and are now being recognized as a serious pathogen under these circumstances. As little is known of the biochemical basis of pathogenicity of this species, interest in the structure and immunological properties of the cell surface polysaccharides of the different chemotypes of this gram-negative bacterium has increased. - The three bacterial colonies used for this investigation were selected from a biochemically pure culture of A. hydrophila. One represented the overall strain, whereas the other two, mutants, were isolated as morphologically different clones. The original strain and one of the clones were sensitive to phage while the other clone was resistant to the same phage. - Lipopolysaccharides were extracted from all three variants, and the basic structures of the polysaccharide portion from each of the three ...
Bacteriophages are an important repository of genetic diversity. As one of the major constituents of terrestrial biomass, they exert profound effects on the earths ecology and microbial evolution by mediating horizontal gene transfer between bacteria and controlling their growth. Only limited genomic sequence data are currently available for phages but even this reveals an overwhelming diversity in their gene sequences and genomes. The contribution of the T4-like phages to this overall phage diversity is difficult to assess, since only a few examples of complete genome sequence exist for these phages. Our analysis of five T4-like genomes represents half of the known T4-like genomes in GenBank. Here, we have examined in detail the genetic diversity of the genomes of five relatives of bacteriophage T4: the Escherichia coli phages RB43, RB49 and RB69, the Aeromonas salmonicida phage 44RR2.8t (or 44RR) and the Aeromonas hydrophila phage Aeh1. Our data define a core set of conserved genes common to these

Some bacteria use pheromones (N-acylhomoserine lactones or AHLs) to determine their population density. Salmonella does not make AHLs but it can detect the AHLs produced by other bacteria. We hypothesized that Salmonella would detect AHLs made by the normal intestinal flora and use this information to adjust its gene expression accordingly. Surprisingly, we discovered that the normal gut flora does not make AHLs and instead, Salmonella is detecting the AHL production of other pathogens in the gut. Salmonella can detect the AHL production of Aeromonas hydrophila in turtles and Yersinia enterocolitica in mice. We are characterizing this same AHL detection system in E. coli, Klebsiella, Enterobacter and other closely related organisms.. 2. Coordination of metabolism and virulence by SirA and CsrA ...
The experimental investigation of microorganisms capable of producing hydrogen for subsequent fuel cell use is described. The microorganisms Clostridium welchii, Aeromonas hydrophila and Bacillus polymyxa were screened using various substrates. Rate studies with E. coli on maltose and glucose and Pseudomonas sp. (G4A) on formate and glucose were conducted. The manner in which hydrogen is produced demonstrates the desirability of following the course of reaction continually. Full factorial studies, with three factors at two levels, were conducted with several organism-substrate systems. Along with results obtained from previous factional factorial experiments, further definition of the criteria for maximizing hydrogen production has been established. Scale-up studies with E. coli-glucose show that the factors governing laboratory scale studies are applicable to large volume fermenters. (Author)(*FUEL CELLS

The swamp eel (Monopterus albus) is an important commercial farmed fish species in China. However, it is susceptible to Aeromonas hydrophila infections, resulting in high mortality and considerable economic loss. Povidone-iodine (PVP-I) is a widely used chemical disinfectant in aquaculture, which can decrease the occurrence of diseases and improve the survival. However, environmental organic matter could affect the bactericidal effectiveness of PVP-I, and the efficacy of PVP-I in aquaculture water is still unknown. In this paper, disinfection assays were conducted to evaluate the effectiveness of PVP-I against the A. hydrophila in different types of water. We found that the effective germicidal concentration of PVP-I in outdoor aquaculture water was 25 ppm during 12 hours. In indoor aquaculture water with 105 CFU/mL bacteria, 10 ppm and 20 ppm of PVP-I could kill 99 % and 100 % of the bacteria, respectively. The minimal germicidal concentration of PVP-I in deionized distilled water and ...
We have investigated the usefulness of ribotyping for the differentiation of aeromonads isolated from five patients with gastroenteritis and from the source water, treatment plant, and distribution system of a small public water supply. Aeromonas hydrophila and Aeromonas caviae were isolated from fecal specimens preserved in Cary-Blair transport medium by using blood ampicillin agar or alkaline peptone water (pH 8.4) subcultured to blood ampicillin agar plates. A. hydrophila, Aeromonas sobria, and A. caviae were isolated from duplicate 100-ml water samples by the membrane filter technique by using ampicillin dextrin agar for quantitative determination of growth and alkaline peptone water enrichment for detection of the presence or absence of aeromonads below the detection limit of the membrane filter method. In addition, free chlorine residuals and pH values were determined for all water samples and heterotrophic plate counts and total and fecal coliform analyses were performed on them. ...

Presently, the long term objective of our laboratory is to determine the role of Aeromonas hydrophila virulence factors in the pathogenesis of disease in man. The virulence factors presently reported in the literature associated with A. hydrophila have not been defined clearly. A. hydrophila, a member of the family Vibrionaceae, is considered to be a significant human pathogen. This microorganism is responsible for a variety of diseases including acute bacterial diarrhea, septicemia, meningitis, endocarditis, corneal ulcers, peritonitis, and wound infections. These diseases have occurred in immunocompetent and well as immunocompromised individuals. A. hydrophila produce as well as possess a number of factors which contribute to the overall virulence of the organism. We have characterized two enterotoxins biochemically, biologically and antigenically. We have identified the genes for both enterotoxins and have cloned them. A complete nucleotide sequence analysis of the cytolytic enterotoxin gene ...
Aeromonas is a genus of Gram-negative, facultative anaerobic, rod-shaped bacteria that morphologically resemble members of the family Enterobacteriaceae. Most of the 14 described species have been associated with human diseases. The most important pathogens are A. hydrophila, A. caviae, and A. veronii biovar sobria. The organisms are ubiquitous in fresh and brackish water. They group with the gamma subclass of the Proteobacteria. Two major diseases associated with Aeromonas are gastroenteritis and wound infections, with or without bacteremia. Gastroenteritis typically occurs after the ingestion of contaminated water or food, whereas wound infections result from exposure to contaminated water. In its most severe form, Aeromonas spp. can cause necrotizing fasciitis, which is life-threatening, usually requiring treatment with antibiotics and even amputation. Although some potential virulence factors (e.g. endotoxins, hemolysins, enterotoxins, adherence factors) have been identified, their precise ...
The bactericidal properties of cow urine have been known to humans from a long time. Cow urine is an effective antibacterial agent against a broad spectrum of Gram-negative and Gram-positive bacteria. In this work, we explored photoactivated cow urine as a potential antimicrobial agent. The antimicrobial activity of cow urine was tested by agar well method using Gram-positive bacteria Bacillus cereus (MTCC-1305), Staphylococcus aureus (MTCC-3160) and Gram-negative bacteria Salmonella typhimurium (MTCC-1253), Aeromonas hydrophila (MTCC-1739), Enterobacter aerogenes (MTCC-2823), Micrococcus luteus (MTCC-1809). Photoactivated urine showed highest antimicrobial activity against Gram-positive Bacillus cereus and Gram-negative bacteriaAeromonas hydrophila . Bactericidal effect showed against various bacteria depended on the concentration of photoactivated urine and the type of bacteria.. ...
A modified fluorescence in situ hybridization (FISH) method was used to analyze bacterial prey composition in protistan food vacuoles in both laboratory and natural populations. Under laboratory conditions, we exposed two bacterial strains (affiliated with beta- and gamma-Proteobacteria - Aeromonas hydrophila and Pseudomonasfluorescens, respectively) to grazing by three protists: the flagellates Bodo saltans and Goniomonas sp., and the ciliate Cyclidium glaucoma. Both flagellate species preferably ingested A. hydrophila over P. fluorescens, while C glaucoma showed no clear preferences. Differences were found in the digestion of bacterial prey with B. saltans digesting significantly faster P. fluorescens compared to two other protists. The field study was conducted in a reservoir as part of a larger experiment. We monitored changes in the bacterial prey composition available compared to the bacteria ingested in flagellate food vacuoles. Bacteria detected by probe HGC69a (Actinobacteria) and ...
Results: Twenty-four cases were encountered at our institution (20 cases with A. hydrophila, 2 with A. caviae, and 2 with A. veronii biovar sobria bacteremia) during the 16-years study period. The median age of patients was 69 years (range: 17-92) and the majority were men (17/24; 70.8%). Sixteen patients (66.8%) had gastrointestinal manifestation such as diarrhea, vomit, and abdominal pain, and 15 (63%) had jaundice. Bacteremia occurred most often in patients with disease of the hepatobiliary or pancreatic system (45.8%; including 5 pancreatic cancer, 2 cholangiocarcinoma, 2 gallbladder tumor, and 2 liver cirrhosis) and gastrointestinal cancer (16.7%). According to our literature review including our 24 cases, the most frequent pathogen isolated was A. hydrophila (44/73; 60.3%). There was 25 patients (34.2%) with polymicrobial Aeromonas bacteremia and community-acquired blood stream infections due to Aeromonasspecies occurred in 51.6% patients. The overall 30-day mortality was 28.8%. ...

Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess. This can be achieved by immobilization of the organisms using an appropriate system.Two putative immobilization systems, agar entrapment and biofilm formation, wereassessed. Surface attached biofilm growth provided better results with respect to cell retention,proliferation and microbial activity than immobilization in agar beads. Thus, biofilm physiology was further characterized using simplified systems of single, dual or multi strain bacterial consortia containing the key-organisms as well as other wastewater treatment ...
The present study investigated the effects of dietary vitamin A on immune function in the proximal intestine (PI), mid intestine (MI) and distal intestine (DI) of young grass carp (Ctenopharyngodon idella). Fish were fed graded levels of dietary vitamin A for 10 weeks, and then a challenge test using an injection of Aeromonas hydrophila was conducted for 14 d. The results showed that, compared with the optimum vitamin A level, vitamin A deficiency significantly decreased fish growth performance, increased enteritis morbidity, decreased intestinal innate humoral immune response and aggravated intestinal inflammation. However, liver-expressed antimicrobial peptide 2A/B mRNA in the DI and IL-6, IL-17D, IL-10, transforming growth factor (TGF)-β1 and TGF-β2 mRNA in the PI were not affected by vitamin A levels. Meanwhile, vitamin A deficiency disturbed inflammatory cytokines in the PI, MI and DI, which might be partly linked to p38 mitogen-activated protein kinase (p38MAPK) signalling and NF-κB ...
Hardy Diagnostics ColiScreen™ is to be used as a rapid screening test to assist in the identification of E. coli. The performance of a spot indole test alone is not an adequate screen for E. coli, since there are at least 52 species of gram-negative bacilli that grow on MacConkey, are indole-positive, and ferment lactose. The more common ones include Klebsiella oxytoca, Citrobacter freundii, C. sedlakii, C. braakii, C. koserii, C. amalonaticus, C. youngae, Aeromonas hydrophila and Serratia odorifera. The test is designed to be used on isolates demonstrating typical appearance on EMB and/or MacConkey Agar. Although most E. coli exhibit lactose-fermentation on these media, it should be noted that approximately 5% of E. coli are non-lactose-fermenters.(2) Using this test system, glucuronidase-positive, indole-positive, gram-negative organisms are presumptively identified as E. coli. Hydrolysis of the additive nitrophenyl-beta-glucopyranosiduronic acid denotes the production of glucuronidase and ...
The general objective of this PhD Thesis was to determine the prevalence of Aeromonas spp. found by sequencing the rpoD gene among the 1365 identified strains. Two types of tertiary treated reclaimed water, one after a lagooning and the other after UV and chlorine (UV+ Cl) treatment were, together with other environmental waters, the dominating origin of the isolates (n=543), followed by 416 strains from human clinical samples and 203 that came from fish (carp and trouts), vegetable irrigated with the reclaimed water and shellfish. The most relevant findings were that the lagooning system only reduced in an 82% the concentration of Aeromonas vs the 100% elimination after UV+Cl. However, re-growth was observed in the stored water use for irrigation.

While some microbes can cause infectious diseases, other microbes are vital for the development and physiology of the host. Although it is known that microbes affect host health and development, the colonization dynamics of these microbes are still unknown. In the Guillemin lab, we study these host-microbe interactions using zebrafish as a model organism to understand how microbes colonize the host gut. Aeromonas is a normal bacterial resident of the zebrafish gut that we recently discovered produces an uncharacterized double cache domain containing protein ZOR0001_03237 (3237). This protein, 3237, affects the colonization of Aeromonas in zebrafish by decreasing the rate of colonization. To further explore how 3237 could be involved in colonization, we investigated the predicted structure for clues. Based on sequence, 3237 is hypothesized to have a periplasmic ...

Infections due to Aeromonas hydrophila and Plesiomonas shigelloides in immuno-compromised hosts have been well documented, but the role of these organisms in causing gastrointestinal disease in healthy persons is controversial. Despite difficulties in characterizing the exotoxins produced by Aeromonas species, there is accumulating evidence that these bacteria are capable of causing usually mild, self-limited diarrheal disease in previously healthy adults. Some pediatric patients may have protracted dysenteric symptoms. P.
ABSTRACT: Ornamental goldfish Carassius auratus were treated with whole cell (WC), extracellular product (ECP), outer membrane protein (OMP) and biofilm (BF) vaccines developed from the virulent Aeromonas hydrophila (AHV1; GenBank HQ331525.1) with and without the immunoadjuvant Asparagus racemosus. On various days post-vaccination (dpv), the treated fish were challenged with virulent A. hydrophila. These fish were monitored for survival, growth, specific bacterial reduction, and biochemical, haematological and immunological parameters. C. auratus attained 100% mortality within 7 d in non-vaccinated groups, whereas the vaccines helped to significantly (p ≤ 0.001) increase survival after 25 and 50 dpv. The vaccines with immunoadjuvant (ECP2, OMP2 and BF2 treatments) helped to reduce the Aeromonas load after the challenge, and serum albumin, globulin and protein levels were significantly (p , 0.01) improved in the OMP2- and BF2-treated groups. Haemoglobin and red blood cell counts were also ...
This study was to investigate the effect of dietary thiamin on the immune response and intestinal microflora in juvenile Jian carp (Cyprinus carpio var. Jian). Seven diets (0.25, 0.48, 0.79, 1.06, 1.37, 1.63 and 2.65 mg thiamin kg−1) were fed to Jian carp (8.20 ± 0.02 g). At the end of feeding trial, red blood cell counts and white blood cell counts increased with increasing dietary thiamin levels up to 0.79 and 1.06 mg kg−1 diet, respectively (P , 0.05); Lactobacillus counts in intestine increased gradually, and maximum values obtained when the thiamin level was at 0.79 mg kg−1 diet (P , 0.05). After the feeding trial, fish were injected with Aeromonas hydrophila only one time on the first day of the challenge trial and fed the same diets as the growth trial for 17 days. The survival rate, leucocyte phagocytic activity, lectin potency, acid phosphatase activity, lysozyme activity, total iron-binding capacity and immunoglobulin M content of fish after being injected with A. hydrophila ...

Glucan was extracted from yeast (Saccharomyces cerevisiae) and subjected to chemical analy- ses. Thin layer chromatography (TLC) revealed that glucan is primarily composed of glucose units and contains 97.2% glucose. Infrared spectrum showed a major band at 883/cm, suggest- ing that glucan is linked to β-glycosidic. Intraperitoneal administration of different doses of glu- can enhanced the survival rate of carp (Cyprinus carpio) infected by Aeromonas hydrophila. When a concentration above 500 μg glucan per fish was administered, survival relative to the uninfected control was 100%. The total leukocyte count and neutrophil and monocyte popula- tions increased after administration of the glucan. The maximum effect occurred on day 6 after injection. Macrophages of compound-administrated test animals significantly increased produc- tion of superoxide anions, efficiently killing the bacterial pathogen. This study showed that glu- can can be effective in inducing non-specific cellular defense ...
S04-690, from the Mississippi fish, also was found to be in the same group, related to both the U.S. catfish and Asian carp bacteria. However, it was genetically distinct from the other two strains. By contrast, A. hydrophila strains that do not cause epidemics are more heterogeneous.. Additional experiments found that isolated bacteria from diseased catfish in America and diseased carp in China shared alternate forms of 10 key housekeeping genes required for basic cellular function.. Its not clear how the bacterium was introduced in America, Liles says. It could be from importing Asian carp to America for aquatic weed control, or from transporting ornamental fish or contaminated processed seafood products from Asia. The spread of disease among farms also is not fully understood but could result from birds that move from pond to pond eating catfish, or from harvesting equipment that may be insufficiently sanitized between uses.. Liles and other researchers are investigating means to control ...

Antimicrobial resistant bacteria are emerging biological contaminants of the environment. In aquatic ecosystems, they originate mainly from hospitals, livestock manure and private households sewage water, which could contain antimicrobial agents and resistant microorganisms. Aeromonas spp. occur ubiquitously in aquatic environments and they cause disease in fish. Motile aeromonads are also associated with human gastrointestinal and wound infections and fish can act as a transmission route of antimicrobial resistance (AMR) aeromonads to humans. The environmental ubiquity, the natural susceptibility to antimicrobials and the zoonotic potential of Aeromonas spp. make them optimal candidates for studying the AMR in aquatic ecosystems. The AMR patterns of 95 motile aeromonads isolated from freshwater fish during 2013 and 2016 were analyzed. All samples from fish came from farms and natural water bodies located in northern Italy, which is an area characterized by high anthropic impact on the environment. The
DNA adenine methyltransferase (Dam) is widespread and conserved among the γ-proteobacteria. Methylation of the Ade in GATC sequences regulates diverse bacterial cell functions, including gene expression, mismatch repair and chromosome replication. Dam also controls virulence in many pathogenic Gram-negative bacteria. An unexplained and perplexing observation about Escherichia coli Dam (EcoDam) is that there is no obvious relationship between the genes that are transcriptionally responsive to Dam and the promoter-proximal presence of GATC sequences. Here, we demonstrate that EcoDam interacts with a 5-base pair non-cognate sequence distinct from GATC. The crystal structure of a non-cognate complex allowed us to identify a DNA binding element, GTYTA/TARAC (where Y = C/T and R = A/G). This element immediately flanks GATC sites in some Dam-regulated promoters, including the Pap operon which specifies pyelonephritis-associated pili. In addition, Dam interacts with near-cognate GATC sequences (i.e. ...

Identification and expression profiles of multiple genes in Nile tilapia in response to bacterial infections. Veterinary Immunology and Immunopathology. 144:111-119. Interpretive Summary: To understand how Nile tilapia responds to bacterial infection at molecular level, a subtractive library was constructed. A total of 31 unique genes were identified from the subtractive library. Nine of the 31 ESTs were significantly induced in Nile tilapia at 6h post infection with A. hydrophila at an injection dose that caused ~20% mortality. Of the nine induced genes, four were also significantly induced in Nile tilapia at 6h post infection with A. hydrophila at an injection dose that caused ~60% mortality. Of the four genes induced by A. hydrophila at both injection doses, three were also significantly induced at 6h post infection with Streptococcus iniae at dose that caused ~70% or ~30% mortality. The ...
Several approaches have been developed to estimate both the relative and absolute rates of speciation and extinction within clades based on molecular phylogenetic reconstructions of evolutionary relationships, according to an underlying model of diversification. However, the macroevolutionary models established for eukaryotes have scarcely been used with prokaryotes. We have investigated the rate and pattern of cladogenesis in the genus Aeromonas (γ-Proteobacteria, Proteobacteria, Bacteria) using the sequences of five housekeeping genes and an uncorrelated relaxed-clock approach. To our knowledge, until now this analysis has never been applied to all the species described in a bacterial genus and thus opens up the possibility of establishing models of speciation from sequence data commonly used in phylogenetic studies of prokaryotes. Our results suggest that the genus Aeromonas began to diverge between 248 and 266 million years ago, exhibiting a constant divergence rate through the Phanerozoic, ...

Our research activities are mainly concerned with the transition from the grain level to the REV level, from experimental and modeling vantage points, without excluding, however, the REV-to-structures transition issue. On the one hand, observations coming from the scanning electronic microscope, X-ray tomography and also destructive tests on individual grains, are designed to characterize the grain scale. These observations are then related to the stress - strain - strength relationship at the REV scale. In particular, a set of 3 triaxial cells (for samples of 70mm, 250mm and 1000mm, respectively) is employed to investigate the effect of grain breakage, whose amount is determined through grain size distributions (GSD) after loading, on the strength properties of dry frictional crushable soils (with maximum grain diameter of 12mm, 40mm and 160mm with regard to the respective sample size). On the other hand, from a numerical point of view, a homogenization procedure has been successfully developed ...
