Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. 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 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.
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).

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

Mesophilic Aeromonas sp. strains like strain AH-3 (serotype O34) showed at least two different UDP-sugar epimerases: GalE, with the unique enzymatic activity of UPD-Gal epimerase responsible for the conversion of UPDGlc to UDPGal, and Gne, with two enzymatic activities, UDP-Gal and UDPGalNAc 4-epimerase, responsible for the conversion of UDPGlcNAc to UDPGalNAc. It is clear that these epimerases are critical for the biosynthesis of the different surface carbohydrates, like capsular polysaccharide, O-antigen, and core LPS. While in several enterobacteria like E. coli or S. enterica serovar Typhimurium GalE is the unique UDP-Gal epimerase, and their mutations correlate with changes in the LPS chemical structure (in many cases with the lack of the O-antigen LPS), no changes were observed in A. hydrophila AH-3 when this mutation occurred. The reason is that Gne (an enzyme not found in many enteric bacteria) is able to perform UPD-Gal epimerization as well as UDPGalNAc 4-epimerization. As we ...
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
2015 Elsevier Ltd. Type III secretion systems (T3SSs) are adopted by pathogenic bacteria for the transport of effector proteins into host cells through the translocon pore composed of major and minor translocator proteins. Both translocators require a dedicated chaperone for solubility. Despite tremendous efforts in the past, structural information regarding the chaperone-translocator complex and the topology of the translocon pore have remained elusive. Here, we report the crystal structure of the major translocator, AopB, from Aeromonas hydrophila AH-1 in complex with its chaperone, AcrH. Overall, the structure revealed unique interactions between the various interfaces of AopB and AcrH, with the N-terminal molecular anchor of AopB crossing into the N-terminal arm of AcrH. AopB adopts a novel fold, and its transmembrane regions form two pairs of helical hairpins. From these structural studies and associated cellular assays, we deduced the topology of the assembled T3SS translocon; both ...

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 ...

[Aeromonas hydrophila in Ivory Coast Epidemiologic and ecologic aspects and its enteropathogenic role].: A research based on the analysis of 479 coprocultures ,
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, ...

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.

Variation in acid production from carbohydrate metabolism has been identified in ,italic,Aeromonas,/italic, as a potential indicator for new subspecies. Therefore, pure cultures of non-lactose fermenting ,italic,Aeromonas caviae,/italic,, a cause of waterborne infections in humans and other vertebrates, were studied after noting a mixture of acid producing and non-acid producing colonies after four days of incubation on MacConkey agar at ambient temperature. Unusual arabinose negative strains of ,italic,A. hydrophila,/italic, (usually arabinose positive) were added to the project to further study the correlation between carbohydrate fermentation and taxonomy. These metabolic variants of ,italic,A. caviae,/italic, and ,italic,A. hydrophila,/italic, were studied for phenotypic differences via carbohydrate utilization assays as well as genotypic differences via FAFLP. The results suggest that the ,italic,A. caviae,/italic, isolates MB3 and MB7 should be considered novel subspecies, while the ...
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 ...
Members of the genus Aeromonas collectively occupy diverse niches ranging from free-living states in the environment to close associations with animals, sometimes causing disease in their hosts (1, 2). In the environment, Aeromonas spp. are most commonly associated with aquatic habitats, and as such, water sources are of particular interest, since they represent potential contamination routes that may impact human and animal health and disease. Some Aeromonas spp. are also implicated in opportunistic infections in humans; the majority of these have been identified as A. hydrophila, A. veronii, and A. caviae (3), although as classification of the species within this genus continues to improve, other aeromonad species, such as A. dhakensis, have also been suggested to be important infectious agents (4-6). To date, there are 31 established or proposed species of Aeromonas (7).. Aeromonas lusitana sp. nov. strain DSM 24905T (=CECT 7828T, =11/6T, =MDC 2473) was isolated from a hot spring water sample ...
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 ...
An 83-year-old man was admitted to our emergency department with the chief complaints of fever and hemoptysis. He presented with severe hemorrhage from both lungs and eventually died approximately 7 hours after admission. Pathological autopsy revealed right lower and middle lobe pneumonia with profuse lung hemorrhage. Aeromonas hydrophila was isolated on culture of blood, sputum, and lung specimens. The pathological autopsy results showed bilateral lobar pneumonia with profuse lung hemorrhage. The patient had a fulminant disease course with rapid progression. We suspected essential thrombocytosis based on the blood examination findings. Here, we report our findings on this rare case of A. hydrophila pneumonia with extensive alveolar hemorrhage and essential thrombocytosis and provide a short literature review. ...
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.. ...
Oral vaccination is a relevant alternative for fish immunisation in intensive culture. However, its effectiveness is limited by possible vaccine degradation in the fish digestive system. The purpose of this work was to obtain stable biocompatible alginate microparticles entrapping inactive Aeromonas hydrophila cells for fish oral immunisation. The particles were prepared through an emulsion-based methodology, employing different vegetable oils containing the surfactant Span 80, varying the ratio between aqueous alginate and oil phases, the stirring rate and the initial concentration of A. hydrophila. Microparticles stable under gastrointestinal conditions presenting mean diameters lower than 50 mu m were obtained with 1:9 (v/v) of aqueous phase containing 3.5% alginate (w/v) in relation to the oil phase (corn oil with 0.2% v/v Span 80) under stirring at 2000 rpm, with bacterium encapsulation efficiencies up to 100%.

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 condensed tannins (CT) on intestinal immune function in on-growing grass carp (Ctenopharyngodon idella). A total of 540 healthy grass carp were fed six diets containing different levels of CT (0, 10·00, 20·00, 30·00, 40·00 and 50·00 g/kg diet) for 70 d and then challenged with Aeromonas hydrophila for 14 d. The results showed that, compared with the control group, dietary CT (1) induced intestinal histopathological lesions and aggravated enteritis; (2) decreased lysozyme and acid phosphatase activities, complement 3 (C3), C4 and IgM contents and down-regulated the Hepcidin, liver-expressed antimicrobial peptide (LEAP)-2A, LEAP-2B, Mucin2 and β-defensin-1 mRNA levels in the proximal intestine (PI), mid intestine (MI) and distal intestine (DI) (P , 0·05); (3) down-regulated the mRNA levels of anti-inflammatory cytokines transforming growth factor (TGF)-β1, TGF-β2 (not in MI and DI), IL-4/13A (not IL-4/13B), IL-10 and IL-11 partly correlated ...
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 present study evaluated the effects of dietary inulin on growth performance, body composition, serum, biochemical, and mucus immune factors; as well as innate immune responses of rainbow trout fry challenged with Aeromonas hydrophila. Four diets were prepared using a commercially available fish feed as a basal diet and different levels of prebiotic inulin incorporation; 0 (control), 1, 2, and 3%; referred to as C, T1, T2, and T3, respectively. The findings of the 60-day feeding trial showed that inulin inclusion affected final weight, food conversion rate (FCR), and specific growth rate (SGR) compared to that of the control group (P , 0.05), in which the lowest FCR was observed in T3. Body composition analysis revealed that inulin significantly increased protein content and decreased lipid levels, especially in the T1 and T2 groups. The lowest ash level was noticed in T2 (P , 0.05). Blood total protein, albumin, globulin, cholesterol, and glucose were not affected by inulin supplementation ...

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. The same strain (ERIC genotrype) of A. caviae was found in the water used for irrigation and in the irrigated lettuce, as occurred for a strain of A. saranelli found in the parsley and in the tomatoes, indicating the origin for the strains in the ...
The gut microbiota consists of a diverse community of microbes, living within the digestive tracts of humans, animals, and insects. 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 ...
Many virulence factors have been described for opportunistic pathogens within the genus Aeromonas. Polymerase Chain Reactions (PCRs) are commonly used in population studies of aeromonads to detect virulence-associated genes in order to better understand the epidemiology and emergence of Aeromonas fr …

Susanne Gebhard, University of Bath. The fast-paced changes in our society, economy and environment create demand for adaptable construction materials. Capabilities that are desirable range from adapting to harsher cycles of wind and rain, to drastically increasing durability in the context of recycling and reuse, to responding to the evolving needs of occupants over multiple timescales. This symposium aims to bring together scientists and designers working on various aspects of adaptable construction materials. The scope includes passive as well as active solutions, e.g. self-healing concrete, self-strengthening soil, and active materials. Contributions on mechanics-related applications of microbiology-enabled solutions are particularly encouraged. The symposium will ideally feature a combination of experimental and modelling techniques, from the microstructural scale of materials to the macro-scale of engineering applications.. Topics of Interest Include:. ...
