Phylogenetic analysis of the genus Aeromonas based on two housekeeping genes. (1/55)

The phylogenetic relationships of all known species of the genus Aeromonas, and especially Aeromonas bestiarum and Aeromonas salmonicida, were investigated on 70 strains using the rpoD sequence, which encodes the sigma70 factor. This analysis was complemented with the sequence of gyrB, which has already proven useful for determining the phylogenetic relationships in the genus. Nucleotide sequences of rpoD and gyrB showed that both genes had similar substitution rates (< 2 %) and a similar number of variable positions (34 % for rpoD versus 32 % for gyrB). Strain groupings by analysis of rpoD, gyrB and a combination of both genes were consistent with the taxonomic organization of all Aeromonas species described to date. However, the simultaneous analysis of both clocks improved the reliability and the power to differentiate, in particular, closely related taxa. At the inter-species level, gyrB showed a better resolution for differentiating Aeromonas sp. HG11/Aeromonas encheleia and Aeromonas veronii/Aeromonas culicicola/Aeromonas allosaccharophila, while rpoD more clearly differentiated A. salmonicida from A. bestiarum. The analysis of rpoD provided initial evidence for clear phylogenetic divergence between the latter two species.  (+info)

Structural studies of the capsular polysaccharide and lipopolysaccharide O-antigen of Aeromonas salmonicida strain 80204-1 produced under in vitro and in vivo growth conditions. (2/55)

Aeromonas salmonicida is a pathogenic aquatic bacterium and the causal agent of furunculosis in salmon. In the course of this study, it was found that when grown in vitro on tryptic soy agar, A. salmonicida strain 80204-1 produced a capsular polysaccharide with the identical structure to that of the lipopolysaccharide O-chain polysaccharide. A combination of 1D and 2D NMR methods, including a series of 1D analogues of 3D experiments, together with capillary electrophoresis-electrospray MS (CE-ES-MS), compositional and methylation analyses and specific modifications was used to determine the structure of these polysaccharides. Both polymers were shown to be composed of linear trisaccharide repeating units consisting of 2-acetamido-2-deoxy-D-galacturonic acid (GalNAcA), 3-[(N-acetyl-L-alanyl)amido]-3,6-dideoxy-D-glucose[3-[(N-acetyl-L-alanyl)amido]-3 -deoxy-D-quinovose, Qui3NAlaNAc] and 2-acetamido-2,6-dideoxy-D-glucose (2-acetamido-2-deoxy-D-quinovose, QuiNAc) and having the following structure: [-->3)-alpha-D-GalpNAcA-(1-->3)-beta-D-QuipNAc-(1-->4)-beta-D-Quip3NAlaNAc-(1-]n, where GalNAcA is partly presented as an amide and AlaNAc represents N-acetyl-L-alanyl group. CE-ES-MS analysis of CPS and O-chain polysaccharide confirmed that 40% of GalNAcA was present in the amide form. Direct CE-ES-MS/MS analysis of in vivo cultured cells confirmed the formation of a novel polysaccharide, a structure also formed in vitro, which was previously undetectable in bacterial cells grown within implants in fish, and in which GalNAcA was fully amidated.  (+info)

Genetic diversity among A-proteins of atypical strains of Aeromonas salmonicida. (3/55)

The virulence array protein gene A (vapA) encoding the A-protein subunit of the surface layer of 23 typical and atypical strains of Aeromonas salmonicida from salmonids and marine fish species were sequenced, and the deduced A-protein sequences compared. The A-proteins of the typical A. salmonicida ssp. salmonicida strains were shown to be identical, while amino acid variability was revealed among A-proteins of atypical strains. The highest amino acid variability appears to be in a predicted surface exposed region and is believed to result in antigenic differences among the atypical strains of A. salmonicida.  (+info)

A deterministic model for the dynamics of furunculosis in chinook salmon Oncorhynchus tshawytscha. (4/55)

Studies were undertaken to determine the parameters of transmission of Aeromonas salmonicida in chinook salmon Oncorhynchus tshawytscha, and to develop a deterministic model of the dynamics of experimental furunculosis. For determination of disease transmission coefficient (beta), disease-related mortality rate (alpha) and natural mortality rate (gamma), fish in 70 tanks (approximately 42 fish tank(-1)) were each exposed to a single infectious donor fish, 7 tanks were randomly selected daily and all individuals were examined for the presence of A. salmonicida in the kidney. The proportion of susceptible (S), infected (I) and removed (R, dead) individuals were determined daily. The parameters beta, alpha, gamma, reproductive ratio (R0) and threshold density were estimated to be 0.0214 infected ind. d(-1), 0.29 infected ind. d(-1), 0.00015 ind. d(-1), 3.23 and 13.56 ind., respectively. Using these parameters, a deterministic disease model of A. salmonicida infection as a cause of furunculosis was constructed. The net rate at which new individuals became infected (the incidence rate) per unit time was proportional to S x I x beta. The model-produced data for S were significantly associated with experimental data (r2 = 0.92). In brief, a simple SIR (susceptible-infected-removed) model was successfully utilized to simulate observed data  (+info)

Attenuated virulence of an Aeromonas salmonicida subsp. salmonicida type III secretion mutant in a rainbow trout model. (5/55)

Aeromonas salmonicida subsp. salmonicida is the causative agent of furunculosis, a severe systemic disease affecting salmonid fish. This bacterium contains a type III protein secretion system that is responsible for the secretion and translocation of the ADP-ribosylating toxin, AexT, into the cytosol of fish cells. This study showed that inactivation of the type III secretion system by marker-replacement mutagenesis of the gene ascV, which encodes an inner-membrane component of the type III secretion system, attenuated virulence in a rainbow trout model. The isogenic ascV deletion mutant was phagocytosed by peripheral blood leukocytes but the wild-type (wt) A. salmonicida subsp. salmonicida isolate was not. Histological examination of fish experimentally infected with the wt bacterium revealed extensive tissue necrosis and bacterial aggregates in all organs examined, including the heart, kidney and liver, indicating that the isolate established a systemic infection. Cumulative mortality of fish experimentally infected with the wt bacterium reached 88%. In contrast, no mortality was observed among fish infected with the same dose of the ascV mutant, and histological examination of fish infected with this strain revealed healthy organs. The results indicate that the type III secretion system of A. salmonicida subsp. salmonicida is required to establish systemic infection.  (+info)

Standardization of a broth microdilution susceptibility testing method to determine minimum inhibitory concentrations of aquatic bacteria. (6/55)

A multiple laboratory study was conducted in accordance with the standards established by the Clinical and Laboratory Standards Institute (CLSI), formerly the National Committee for Clinical Laboratory Standards (NCCLS), for the development of quality control (QC) ranges using dilution antimicrobial susceptibility testing methods for bacterial isolates from aquatic animal species. QC ranges were established for Escherichia coli ATCC 25922 and Aeromonas salmonicida subsp. salmonicida ATCC 33658 when testing at 22, 28 and 35 degrees C (E. coli only) for 10 different antimicrobial agents (ampicillin, enrofloxacin, erythromycin, florfenicol, flumequine, gentamicin, ormetoprim/sulfadimethoxine, oxolinic acid, oxytetracycline and trimethoprim/sulfamethoxazole). Minimum inhibitory concentration (MIC) QC ranges were determined using dry- and frozen-form 96-well plates and cation-adjusted Mueller-Hinton broth. These QC ranges were accepted by the CLSI/NCCLS Subcommittee on Veterinary Antimicrobial Susceptibility Testing in January 2004. This broth microdilution testing method represents the first standardized method for determining MICs of bacterial isolates whose preferred growth temperatures are below 35 degrees C. Methods and QC ranges defined in this study will enable aquatic animal disease researchers to reliably compare quantitative susceptibility testing data between laboratories, and will be used to ensure both precision and inter-laboratory harmonization.  (+info)

Metabolic changes in Atlantic salmon exposed to Aeromonas salmonicida detected by 1H-nuclear magnetic resonance spectroscopy of plasma. (7/55)

1H-NMR (nuclear magnetic resonance)-based chemometric methods have been applied for the first time to investigate changes in the plasma metabolite profiles of Atlantic salmon Salmo salar as a result of exposure to Aeromonas salmonicida subsp. salmonicida, a Gram-negative bacterium that is the etiological agent of furunculosis. Plasma samples were obtained from salmon that survived 21 d post exposure to A. salmonicida, and from a control group maintained under similar conditions. 1D 1H-NMR spectra were acquired and principal components analysis (PCA) was used to assess differences between the spectral profiles of plasma from salmon that survived an A. salmonicida challenge, and non-infected controls. PCA enables simultaneous comparison of spectra, presenting a simplified overview of the relationship between spectral data, where spectra cluster based on metabolite profile similarities and differences; information regarding the metabolite variations can therefore be readily deciphered. The major metabolite changes responsible for the spectral differences were related to modification in the lipoprotein profile and choline-based residues, with minor changes in carbohydrates, glycerol, trimethylamine-N-oxide and betaine. These changes indicated that exposure to A. salmonicida induced a characteristic biochemical response which could be used to determine the health status of salmon. This study suggests that with further development this metabolite profiling technique may be a useful tool for diagnosis of disease states in salmon and could provide a better understanding of the host-pathogen relationship which at present is poorly understood for A. salmonicida and Atlantic salmon.  (+info)

Characterisation of atypical Aeromonas salmonicida infection in Arctic charr Salvelinus alpinus and European grayling Thymallus thymallus. (8/55)

Cultured stocks of Arctic charr Salvelinus alpinus and European grayling Thymallus thymallus are vulnerable to infection by achromogenic atypical Aeromonas salmonicida (AAS). In Finland, natural stocks of both fish species have to be supported by restocking, and AAS infection poses a threat to successful restocking because no preventive means are available. In this study, we analysed AAS isolates from Arctic charr and European grayling and from other sources genetically, and characterised the signs and pathology of AAS infection in Arctic charr and European grayling both under farming conditions and after experimental challenge. AAS outbreaks were recorded in 1 fish farm over an 8 yr period. Among various salmonid fishes under farming conditions, only Arctic charr and European grayling were susceptible to AAS infection. The disease caused by AAS could be reproduced in both species using the same AAS strain in an experimental challenge. The course of the disease and pathology of natural and experimental AAS infection differed between the 2 species, even though only 1 strain was used for challenge. Isolates of AAS from Arctic charr and European grayling were genetically identical within a single river water basin. However, genetic heterogeneity was observed among the isolates from different water basins. In both species, AAS caused systemic infection. The results suggest that the same AAS strain could be used to develop a vaccine to protect both Arctic charr and European grayling from AAS infection.  (+info)

This review summarizes the results of studies on atypical Aeromonas salmonicida (aAS) -infection among farmed Arctic charr (Salvelinus alpinus) and European grayling (Thymallus thymallus) (later referred as charr and grayling, respectively). Specifically, I aimed to characterize the causative agent of aAS -infection, to describe putative virulence factors of the bacteria and cross pathology of the infection in charr and grayling. I also aimed to describe some of the immune defense functions in charr. I also described a concomitant presence of a common fresh water fish parasite, Diplostomum spathaceum, and aAS -bacteria in manifestation of the bacterial infection. The experimental juvenile charr and grayling, originated from Vuoksi, Kymijoki and Inari watercourses in Finland. Several (n=66) aAS isolates from 7 watercourses in Finland and from the Baltic sea were characterized in the study. These were compared to 11 Swedish, 1 Icelandic aAS isolates, to 3 A. salmonicida subsp. salmonicida (ASS) ...

In this study we have examined the levels of protection against infection with a Danish strain of A. salmonicida subsp. salmonicida in both non-vaccinated, as well as vaccinated rainbow trout. Both a commercial vaccine (AlphaJect 3000, PHARMAQ AS) as well as an experimental auto-vaccine was tested. For comparison, the isolated adjuvant used in the commercial vaccine, as well as the one used in the experimental vaccine was included in the experimental setup. The protective effects of the vaccines were tested by bacterial challenge 18 weeks post vaccination, and during the 18 weeks, the development of specific antibodies was monitored using ELISA assays ...
The study was cancelled mid-way through its schedule when we learned that the fish used to putatively recover EEDV from archived material carried an atypical Aeromonas salmonicida infection whose clinical presentation mimicked EED. We had relied on clinical presentation as an indicator of EEDV infection. Subsequent challenges of young-of-the-year lake trout from another source were unsuccessful in producing EEDV infection. Thus, while we thought we had recovered EEDV from archived material, in fact, we had not and did not have the clinical material to continue the study. ...

Aeromonas salmonicida has been recognized as a pathogen of fish for over 100 years. In 1894 Emmerich and Weibel made the first report of its isolation during a disease outbreak at a Bavarian brown trout hatchery. The manifestations of the disease include furuncle-like swelling and, at a later stage, ulcerative lesions on infected trout. Since that time a number of subspecies of Aeromonas salmonicida have been recognized, although the taxonomy of the species is far from settled. While Aeromonas salmonicida was traditionally thought of as a pathogen of salmonids, global reports now confirm that this pathogen has been associated with clinical or covert disease in a variety of salmonid and non-salmonid species in freshwater, brackish water and sea water. Aeromonas salmonicida (strain A449) was isolated from a brown trout in the Eure River, France in 1975 and harbors one chromosome and 5 plasmids. Comparison to the related A.hydrophilia ATCC 7966 (AERHH) show the presence of numerous insertion ...

Mariculture in Denmark is based on production of rainbow trout grown two years in fresh water followed by one growth season in sea cages. Although the majority of rainbow trout are vaccinated against the most serious bacterial pathogens - Aeromonas salmonicida subsp. salmonicida, Vibrio anguillarum and Yersinia ruckeri, by the use of commercially available vaccines, disease outbreaks requiring treatment with antibiotics still occur. The present study tested the potential of a new experimental multicomponent vaccine that is based on local bacterial strains, isolated from rainbow trout in Danish waters, and thus custom-designed for Danish rainbow trout mariculture. The vaccination with the multicomponent vaccine resulted in protection against three relevant bacterial diseases (yersiniosis, furunculosis, vibriosis) under experimental conditions. We showed that i.p. injection of the vaccine induced specific antibody responses in trout against the different bacterial antigens and regulated expression ...
The results of this study revealed that a bacterial communication system termed quorum sensing is involved in regulation of bacterial pathogenicity and production of AsaP1, cytotoxic activity, and a brown pigment secreted by the bacterium. A RT-qPCR based analysis of the innate and adaptive immune response in Arctic charr showed that the immune response triggered by a wild type strain and an AsaP1-deletion strain was significantly different, indicating the importance of AsaP1 in the development of the host defense. Mutants of AsaP1 lacking toxic, but retaining immunogenic properties of the native enzyme, were constructed and transformed into the wild type strain. A bacterin based on a mutant of the bacterium secreting an AsaP1-toxoid was used to vaccinate Arctic charr and found to induce good protection against atypical furunculosis. The results add to the understanding of the pathogen and its interaction with Arctic charr during infection and immunization.. Um doktorsefnið. Johanna Mareile ...
Phage therapy may represent a viable alternative to antibiotics to inactivate fish pathogenic bacteria. Its use, however, requires the awareness of novel kinetics phenomena not applied to conventional drug treatments. The main objective of this work was to isolate bacteriophages with potential to inactivate fish pathogenic bacteria, without major effects on the structure of natural bacterial communities of aquaculture waters. The survival was determined in marine water, through quantification by the soft agar overlay technique. The host specificity was evaluated by cross infection. The ecological impact of phage addition on the structure of the bacterial community was evaluated by DGGE of PCR amplified 16S rRNA gene fragments. The survival period varied between 12 and 91 days, with a higher viability for Aeromonas salmonicida phages. The phages of Vibrio parahaemolyticus and of A. salmonicida infected bacteria of different families with a high efficacy of plating. The specific phages of pathogenic

Non-mac-tropic HIV-1 R5 viruses are predominantly transmitted and persist in immune tissue even in AIDS patients who carry highly mac-tropic variants in the brain. Non-mac-tropic R5 envelopes (Envs) require high CD4 levels for infection contrasting with highly mac-tropic Envs, which interact more efficiently with CD4 and mediate infection of macrophages that express low CD4. Non-mac-tropic R5 Envs predominantly target T-cells during transmission and in immune tissue where they must outcompete mac-tropic variants. Here, we investigated whether Env+ pseudoviruses bearing transmitted/founder (T/F), early and late disease non-mac-tropic R5 envelopes mediated more efficient infection of CD4+ T-cells compared to those with highly mac-tropic Envs. Results: Highly mac-tropic Envs mediated highest infectivity for primary T-cells, Jurkat/CCR5 cells, myeloid dendritic cells, macrophages, and HeLa TZM-bl cells, although this was most dramatic on macrophages. Infection of primary T-cells mediated by all Envs ...
The A. salmonicida A450 LPS O-antigen, encoded by the wbsalmo gene cluster, is exported through an ABC-2 transporter-dependent pathway. It represents the first example of an O-antigen LPS polysaccharide with three different monosaccharides in their repeating unit assembled by this pathway. Until now, only repeating units with one or two different monosaccharides have been described. Functional genomic analysis of this wbsalmo region is mostly in agreement with the LPS O-antigen structure of acetylated l-rhamnose (Rha), d-glucose (Glc), and 2-amino-2-deoxy-d-mannose (ManN). Between genes of the wbsalmo we found the genes responsible for the biosynthesis and assembly of the S-layer (named A-layer in these strains). Through comparative genomic analysis and in-frame deletions of some of the genes, we concluded that all the A. salmonicida typical and atypical strains, other than A. salmonicida subsp. pectinolytica strains, shared the same wbsalmo and presence of A-layer.

The Atlantic cod (Gadus morhua) is an important species for global fisheries and aquaculture industries. A thorough knowledge of the genes and molecular pathways involved in Atlantic cod immune responses will likely lead to the development of new diagnostics, vaccines, and other methods of combating infectious diseases that threaten these industries. Using functional genomic approaches, this research investigated the innate immune response in immune tissues (head kidney and spleen) of Atlantic cod following treatment with bacterial antigens (i.e. formalin-killed, atypical Aeromonas salmonicida, referred to as ASAL) or a viral mimic (i.e. polyriboinosinic polyribocytidylic acid, referred to as pIC). This research led to the identification of 4154 expressed sequence tags (ESTs) that were generated from cDNA libraries enriched for transcripts dysregulated following stimulation with ASAL. From these transcripts, 10 genes with immune-relevant functional annotations were selected for quantitative ...
An oxidase-negative Aeromonas salmonicida was isolated from coho salmon (Oncorhynchus kisutch) suffering from an epizootic of furunculosis at the state hatchery near Belfair, Washington.

Inactivação fotodinâmica combina o uso de luz com um fotosensibilizador, como por exemplo porfirinas, que na presença de oxigénio gera a formação de espécies reactivas de oxigénio, como o oxigénio singleto e radicais livres, que são capazes de oxidar componentes membranares vitais. As principais vantagens da Terapia Fotodinâmica (TFD) são a sua eficiência na inactivação de bactérias, fungos, leveduras e protozoários; o baixo nível de indução de resistência; e o uso de fontes de luz baratas. Para melhor compreender esta técnica, é fundamental compreender o seu mecanismo de acções em alvos celulares. Os lípidos são importantes componentes nas membranas bacterianas, que muito recentemente foram reconhecidos como um dos alvos da PDI, e que podem estar envolvidos no processo de inactivação bacteriana. O principal objectivo deste estudo foi avaliar o efeito de quatro ...

Behaviour of early life stages of the salmonid European grayling Thymallus thymallus was investigated by assessing the timing of larval downstream movement from spawning areas, the depth at which larvae moved and the distribution of juvenile fish during summer in two large connected river systems in Norway. Trapping of larvae moving downstream and electroshing surveys revealed that T. thymallus larvae emerging from the spawning gravel moved downstream predominantly during the night, despite light levels sufficient for orientation in the high-latitude study area. Larvae moved in the water mostly at the bottom layer close to the substratum, while drifting debris was caught in all layers of the water column. Few young-of-the-year still resided close to the spawning areas in autumn, suggesting large-scale movement (several km). Together, these observations show that there may be a deliberate, active component to downstream movement of T. thymallus during early life stages. This research ...

Aeromonas calmonicida is a Gram negative rod shaped bacterium capable of causing furunculosis in salmonid fish and other chronic and inflammatory diseases in goldfish, carp and also salmonids. The surface layer of A. salmonicida, the A-layer, has been demonstrated to be a major virulence factor for the organism , and its subunit A -protein has been purified and its Structural gene vapA has been cloned. The vapA gene from A. salmonicida strain A450 was subcloned (pSC150) and expressed in Escherichia coli. Its DNA sequence was then determined to consist of 1,506 bp encoding a 502-amino acid residue protein, containing a 21- residue signal peptide and a mature protein of 50,778 Dalton. The A-protein assembled on the cell surface in the form of an S-layer was refractile to trypsin cleavage while trypsin digestion of the purified mature protein revealed a highly resistant 39,400 Dalton N-terminal fragment and a 16,700 Dalton C-terminal fragment with moderate resistance, These trypsin-resistant ...
The story of kidnapping and torture victim Patrica Isasa (and her ultimate victory). Some background: The history of Argentina is full of change. Argentina is a very large country, and it became a strong economy after 1875. It received foreign investment, a lot of immigration from Europe, and it developed very effective modern agriculture. Argentina didnt have free elections until 1916. Then, Hipolito Yrigoyen won and became the first elected president. Like many of Argentinas presidents, Yrigoyen became unpopular for economic reasons. The Depression of 1929 resulted in a military coup in Argentina. After World War Two, free elections returned, and Juan Peron was elected president in 1946. His second wife, Eva Peron, was very popular. She became the subject of a famous American popular musical called "Evita". However, she died in 1952. From 1948 to 1951, the peso lost value and inflation increased greatly. Once again, economic troubles in Argentina led to another military coup in 1955. This ...

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
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

While HIV cell-to-cell transmission has been observed in test tube experiments, this is the first study to capture these interactions in a living animal. Although cell-to-cell infection does result in release of abundant solo viral particles, direct transmission from HIV-infected immune cells to other cells-which can then replicate in clusters of these cells-is a much more efficient route to quickly spread the virus, researchers say. It may be particularly important in allowing the virus to spread in the body even before it is detectable in the blood.. Previous studies in cell culture have indicated that cell-to-cell infection may help HIV to resist antibodies and potent therapies. This study provides direct evidence that these interactions do occur in infected immune tissues, and highlight the importance of considering cell-to-cell transmission in developing new treatments.. "All HIV treatment to date has been based on the free-floating virion model," says Benjamin K. Chen, MD, PhD, an ...

Primary and secondary sex traits are influenced by the same sex hormones, and the expression of secondary sex traits may consequently signal males capacity for sperm production. Sperm quality may also be influenced by immune activity, as sperm are non-self to the male. Parasite infections alter immune activity and may thus reduce ejaculate quality. In the Arctic charr (Salvelinus alpinus) the red abdominal colour is considered an ornament that signals important information in mate choice. We captured and individually caged sexually mature male Arctic charr during the spawning period. Afterwards we estimated abdominal colour, parasite infections, gonad mass and several spermatological and immunological variables. Intensity of abdominal colour was positively correlated to testes mass, milt mass and sperm cell numbers produced. Additionally, males with low parasite intensities had high testes mass and produced milt with high sperm density, indicating a trade-off between parasite resistance and ...
With the escalating number of bacterial genome sequences available, CGH microarray analysis is an increasingly popular tool to study pathogenic microorganisms. CGH is a comprehensive analytical tool permitting the examination of multiple bacterial strains at the whole-genome level, providing data about the acquisition and loss of genetic information, the potential evolutionary lineages of pathogens, and the identification of virulence-associated and/or strain-specific genes. Recently, a number of important bacterial pathogens of humans and animals have been analyzed using CGH, including Bordetella pertussis (23), Vibrio cholerae (26), Helicobacter pylori (85), Coxiella burnetti (3), Yersinia pestis (42), and Aeromonas salmonicida (67).. This is the first study to use CGH microarray analysis to compare a collection of uropathogenic and fecal/commensal E. coli isolates. This approach permits the identification of genomic islands and genes specific to UPEC isolates. Genomic DNA from three ...
Investigation of the initial and spoilage microbial diversity of iced stored sea bream was carried out. Culture dependent methods were used for bacterial enumeration and phenotypic identification of bacterial isolates, while culture independent methods, using bacterial 16S rRNA gene amplification, cloning and sequencing of DNA extracted directly from the flesh were also employed. The culture dependent approach revealed that the initial microbiota was dominated by Acinetobacter, Shewanella, Pseudomonas and Flavobacterium, while at the end of shelf-life determined by sensory analysis (16 days), the predominant microbiota was Pseudomonas and Shewanella. Culture independent approach showed that initially the sea bream flesh was strongly dominated by Acinetobacter, while Pseudomonas, Aeromonas salmonicida and Shewanella were the predominant phylotypes at the end of shelf-life. Initial and spoilage microbiota comprised of phylotypes previously identified by others using traditional or molecular ...

Immune tissues are known to be innervated by the sympathetic nervous system, but little is known of what directs the innervation to specific tissue compartments. This report examines the sympathetic innervation of immune tissues in transgenic mice that overexpress nerve growth factor (NGF) in skin and other epithelial structures. NGF transgenic mice exhibited dramatic hyperinnervation in the splenic marginal zone, and the medulla and capsule of peripheral lymph nodes. In contrast, the transgenic mesenteric lymph nodes showed no hyperinnervation. This difference correlated with the location of these nodes; peripheral lymph nodes drain skin where the transgene was expressed while mesenteric lymph nodes drain non-transgene-expressing structures. In addition, the level of innervation correlated with the level of NGF peptide content as assayed by ELISA (3- and 13-fold increase in transgenic spleen and axillary lymph nodes, respectively; no increase in mesenteric nodes) and immunocytochemistry. RT-PCR ...

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 ...

Previously, Adams and coworkers (1) reported the localization of Tet A on an EcoRI restriction fragment approximately 5.4 kb in size in OTr plasmids (pASOT plasmids) from Scottish isolates of A. salmonicida(recovered after furunculosis outbreaks). These workers also showed that OTr-encoding plasmid pRAS1 (originally discovered inA. salmonicida isolated from Atlantic salmon with furunculosis in a fish farm near Bergen, Norway; R.-A. Sandaa, personal communication) carried Tet A on the same fragment. Plasmid pRAS1 has also been shown to possess the IncU replicon (R.-A. Sandaa, A. G. Eide, K. Y. Mazengia, B. K. Thorsen, and Ø.

It was not established whether the pASOT plasmids also contained the IncU replicon. However, it was suggested that the Tet A ...
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 ...

Diethylstilbestrol (DES) is a synthetic compound and considered as an endocrine disruptor that interferes with the normal development of human organs and even immune tissues. DES has been investigated for its immunosuppressive effects, thymic atrophy, and various types of cancer including breast cancer, ovarian cancer, uterine cancer, etc. In this study, we investigated DES regulated mechanisms in T cells and examined whether DES exposure of T cells leads immune suppression and affects immune functions. To this end, we investigated the effect of DES on T cells in vitro and specifically examined DES-induced apoptosis in T cells, expression of genes involved in apoptosis, and differentiation of T helper cells in vitro. We observed significant increase in apoptosis in activated T cells in dose-dependent manner in vitro. Upon examination of FasL expression in activated T cells, there was a significant increase in FasL expression in activated T cells post DES treatment. Furthermore, upon examination of
Prejanopterus is an extinct genus of pterodactyloid pterosaur from the Lower Cretaceous (lower Aptian age) layers of the Leza Formation of La Rioja, Spain. In 1980 a fossil site was discovered near Yacimiento de Fuente Amarga on the western slopes of the Peña Isasa. In 1993 and 1994 ten fossiliferous blocks were recovered, containing numerous disarticulated fossil bones and bone fragments, among them those of a pterosaur. The type species Prejanopterus curvirostra was named and described in 2010 by Carolina Fuentes Vidarte and Manuel Meijide Calvo. The generic name is derived from the village of Préjano and a Latinised Greek pteron, "wing". The specific name is derived from Latin curvus, "bent", and rostrum, "snout", a reference to the distinctive bend to the left which was claimed to be present in all fossils of the snout. A later study indicates that "there is no genuine sideways bend" of the snout, "but a slight dorsal curvature". The same study emended the specific name to curvirostris as ...

Humus is a colloidal organic substance. The tiny humus colloidal particles (micelle) are composed of carbon, hydrogen, and oxygen in the form of polyphenols, poly-quinones polyuronides, and polysaccharides. Most of the properties of humus are its colloidal characteristics. Some important properties of humus are as under:. Color: The color of the humus is brown to dark brown. The typical dark of some soils is due to presence of humus in these soils.. Solubility in Water: The humus is insoluble in water due to its association and divalent and trivalent salts. This property help the humus to stay in the soil not lost by leaching. However, isolated humus is partly soluble in water.. Water Retention Capacity: The water holding capacity of humus on mass basis 4-5 times is that of the silicate clays. It can hold water up to 20 times its mass. This property helps prevent drying and shrinking of soil separates. Also, humus improves moisture retention in sandy soils.. Cation Adsorption and Exchange: The ...
Hirudotherapy has been complicated by infections caused by Aeromonas spp., which are considered endosymbionts of the leech. Leeches were treated by feeding them artificially with 100μg/ml ciprofloxacin using a 0.05 Mol arginine solution as a phagostimulant. Aeromonads were identified using the API 20NE system, and species determined by gyrB sequencing of two representative isolates. Aeromonas spp. were detected in 57 out of 80 control leeches (71.3%), but in none of the 56 leeches treated with ciprofloxacin. Treated leeches survived for up to four months. Tested weekly, leeches took human blood for at least 4 weeks after treatment and were all negative for Aeromonas spp. All water samples in which leeches were kept before treatment were contaminated with Aeromonas spp. but in none of the NaCl/arginine solutions that were used to feed antibiotic treated leeches. Two species were identified: Aeromonas veronii and Aeromonas media. Other environmental bacteria and some filamentous fungi were ...

Nile Tilapia (Oreochromis niloticus) is a very popular aquaculture species in the Philippines at present and considered as an "aquatic chicken" offering economical and social benefits mainly for rural communities. It also play vital role in terms of worldwide employment, however there were reported cases of high mortality rates in different species of Tilapia cause by Aeromonas species (Badillo, 2010). One of the most common bacteria that infect the wild and cultured Tilapia is Aeromonas sobria. Aeromonas sobria is water borne pathogen that are common in almost all aquatic environments including fresh, brackish and marine water. They cause fin rot or skin rot disease and may lead to heavy mortality in cultured tilapia (El-Sayed, 2006). Aeromonas sobria veronii also causes a similar disease in fish including Motile Aeromonas Septicemia in Tilapia (Janda and Abbott, 2010). Bacterial infections, caused by motile members of the genus Aeromonas are among the most common and troublesome diseases of ...
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 ...

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 ...
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.
Neutralophilic bacteria have developed specific mechanisms to cope with the acid stress encountered in environments such as soil, fermented foods- and host compartments. In Escherichia coli, the glutamate decarboxylase (Gad)-dependent system is extremely efficient: it requires the concerted action of glutamate decarboxylase (GadA/GadB) and of the glutamate/GABA antiporter, GadC. Notably, this system is operative also in new strains/species of Brucella, among which Brucella microti, but not in the
Sorex alpinus has slate-colored, near-black fur on its dorsum, while its venter is gray-brown. Its feet are hairless, and its head and body length range from 6.0 cm to 7.7 cm. Its limbs are white, and it has a long, pointed muzzle. It has small, rounded, pink ears; small, black eyes; big, white hind feet; and red-tipped teeth. Both sexes possess lateral scent glands. Tail length ranges from 5.4 cm to 7.5 cm, making its tail nearly as long as its body. The tail is covered in short hair. The dorsal surface is essentially black and the ventral surface is light yellow. Sorex alpinus has five plantar pads on its feet, as opposed to six commonly found in in other shrews). Its weight ranges from 5.5 g to 11.5 g. The physical appearance of S. alpinus is similar to that of S. araneus and S. minutus, but its long tail and darker fur distinguishes S. alpinus from these two species. Sexual dimorphism has not been documented in this species. ("Alpine Shrew", 2004; "Comparison of Species- Shrews", 1990; ...
The studentship is an exciting opportunity to apply existing scientific knowledge to management practices, including interacting directly with resource managers while developing analytical skills with a wide range of applications.. Proper management of natural resources is vital for promoting long-term health in our ecosystems and maintaining cultural identity. Arctic charr (Salvelinus alpinus L.) is an economically and culturally important arctic fish species with established native populations in three Welsh lakes, including Llyn Padarn. By virtue of its native charr population, Llyn Padarn is listed as a Site of Special Scientific Interest, and has been routinely monitored since 2002. Formerly, Llyn Padarn was also an important local charr fishery, that was a unique cultural and recreational feature of the area, however, the current charr population in Llyn Padarn is lower than the lake is expected to support. While the population dynamics of the Llyn Padarn charr are not well known, the ...
Clostridium botulinum C3 exoenzyme inactivates the small GTP-binding protein family Rho by ADP-ribosylating asparagine 41, which depolymerizes the actin cytoskeleton. C3 thus represents a major family of the bacterial toxins that transfer the ADP-ribose moiety of NAD to specific amino acids in acceptor proteins to modify key biological activities in eukaryotic cells, including protein synthesis, differentiation, transformation, and intracellular signaling. The 1.7 A resolution C3 exoenzyme structure establishes the conserved features of the core NAD-binding beta-sandwich fold with other ADP-ribosylating toxins despite little sequence conservation. Importantly, the central core of the C3 exoenzyme structure is distinguished by the absence of an active site loop observed in many other ADP-ribosylating toxins. Unlike the ADP-ribosylating toxins that possess the active site loop near the central core, the C3 exoenzyme replaces the active site loop with an alpha-helix, alpha3. Moreover, structural ...
Surmmary Clinical isolates of Aeromonas were grown at eight different temperatures from 10°C to 40°C. Whole cell lysates were examined by SDS-PAGE and major temperature-dependent changes to both protein and lipopolysaccharide (LPS) profiles were identified. Cells grown at the higher temperatures (37°C and 40°C) produced abundantly a protein of c. 60 kDa which was not detected at the lower temperatures. Temperature-dependent expressions of other proteins were also noted but these were more variable among the isolates. An effect of temperature on expression of lipopolysaccharides was also noted in that some strains produced significantly less O-polysaccharides at the higher temperatures. After fractionation of cells, major differences in the expression of cell envelope and outer-membrane proteins between cells grown at low and high temperatures were noted although no unifying patterns could be discerned. Such growth temperature-induced changes in the cell envelope constituents have not been described
