Elizabethkingia meningoseptica is an infrequent colonizer of the respiratory tract; its pathogenicity is uncertain. In the context of a 22-month outbreak of E. meningoseptica acquisition affecting 30 patients in a London, UK, critical care unit (3% attack rate) we derived a measure of attributable morbidity and determined whether E. meningoseptica is an emerging nosocomial pathogen. We found monomicrobial E. meningoseptica acquisition (n = 13) to have an attributable morbidity rate of 54% (systemic inflammatory response syndrome >2, rising C-reactive protein, new radiographic changes), suggesting that E. meningoseptica is a pathogen. Epidemiologic and molecular evidence showed acquisition was water-source-associated in critical care but identified numerous other E. meningoseptica strains, indicating more widespread distribution than previously considered. Analysis of changes in gram-negative speciation rates across a wider London hospital network suggests this outbreak, and possibly other ...
Elizabethkingia meningoseptica is an emerging nosocomial gram-negative, rod-shaped pathogen in patients with underlying diseases. This bacterium is also considered to be a major pathogen in hospitalized patients. Some of the main risk factors for E. meningosepticum infections include immunosuppression (e.g., end-stage hepatic and renal diseases) and prematurity in neonates. Furthermore, E. meningosepticum could cause pneumonia, endocarditis, and bacteremia in adults. The uncommon resistance pattern of this bacterium, as well as its intrinsic resistance to colistin, makes the treatment of the associated infections challenging unless the susceptibility patterns are available. In this article, we have presented the first case of pulmonary coinfection with multidrug-resistant (MDR) Acinetobacter spp. and E. meningoseptica in Iran. A 20-year-old female patient was admitted to our hospital with tetralogy of fallot as an underlying disease since childhood. The patient underwent cardiac surgery. On the third
For most people, the choice between soft and hard water for everyday use is a matter of preference or geography. Both types have pros and cons. But for catfish, water hardness can make a difference in the development of columnaris disease, which is caused by the bacterium Flavobacterium columnare.. Columnaris disease causes skin and gill lesions, can occur in any freshwater fish species, and costs the US aquaculture industry $40-50 million each year.. Specifically, after exposure to F. columnare, fish in well water from ARSs Harry K. Dupree Stuttgart National Aquaculture Research Center (SNARC) in Stuttgart, Arkansas, develop the disease, but fish in well water from ARSs Warmwater Aquaculture Research Unit (WARU) in Stoneville, Mississippi, do not develop the disease.. "Both waters come from the same aquifer but are very different," says SNARC toxicologist David Straus.. "The water at SNARC is clear and contains significant amounts of calcium and magnesium, the two most common minerals that ...

The ability of Flavobacterium columnare (Flexibacter columnaris) to attach to the gills of common carp, Cyprinus carpio L., was evaluated using a gill perfusion model. A comparison between a high and a low virulence strain of F. columnare was made and evaluated in comparison to results obtained previously with an in vivo model. The ion composition of the water of the organ bath in which the gills were suspended was varied and the influence on adhesion processes assessed. Experiments were carried out to examine the influence of water quality (i.e. nitrite and organic matter) and temperature on the capacity of the bacteria to adhere. It was found that the high virulence strain adhered more readily than the low virulence strain, as was found during the in vivo experiments. Moreover, it was observed that adhesion of the high virulence strain was enhanced by a number of factors. These were immersion of the gill in bivalent, ion-rich water, the presence of nitrite or organic matter, and high ...

Tenacibaculum maritimum is a devastating bacterial pathogen of wild and farmed marine fish with a broad host range and a worldwide distribution. We report here the complete genome sequence of the T. maritimum type strain NCIMB 2154T. The genome consists of a 3,435,971-base pair circular chromosome with 2,866 predicted protein-coding genes. Genes encoding the biosynthesis of exopolysaccharides, the type IX secretion system, iron uptake systems, adhesins, hemolysins, proteases, and glycoside hydrolases were identified. They are likely involved in the virulence process including immune escape, invasion, colonization, destruction of host tissues, and nutrient scavenging. Among the predicted virulence factors, type IX secretion-mediated and cell-surface exposed proteins were identified including an atypical sialidase, a sphingomyelinase and a chondroitin AC lyase which activities were demonstrated in vitro.
Bacteria, parasites, fungi and viruses can all become concentrated in recirculating systems. Bacteria that seem to increase in number in recirculating systems include Aeromonas spp., Vibrio spp., Mycobacterium spp., Streptococcus spp., and Flavobacterium columnare (Columnaris disease) (see UF/IFAS Fact Sheets FA-14 Aeromonas Infections, FA-31 Vibrio Infections of Fish and VM-96 Mycobacteriosis in Fish; UF/IFAS Circular 57 Streptococcal Infections of Fish; and SRAC Publication No. 479b Columnaris Disease, respectively). Parasites that tend to thrive and spread relatively easily in recirculating systems include Trichodina, Ichthyophthirius,Cryptocaryon, Amyloodinium, Costia and monogeneans (see UF/IFAS Circulars 716 Introduction to Freshwater Fish Parasites and 920 Ichthyophthirius multifiliis (White Spot) Infections in Fish; UF/IFAS Fact sheet Amyloodinium Infections in Fish VM-90;and UF/IFAS Fact Sheet FA-28 Monogenean Parasites of Fish, respectively).

Interpretive Summary: Technical Abstract: Primers were designed that selectively amplified by the polymerase chain reaction (PCR) a region of the 16S-23S rDNA intergenic spacer region (ISR) unique to Flavobacterium columnare. The primers were sensitive, capable of detecting 7 colony forming units, and specific for F. columnare. A second goal was to examine horizontal transmission of F. columnare in channel catfish. Two experiments were conducted. In the first, channel catfish fingerlings were injected intramuscularly with F. columnare. Positive detection of F. columnare in tank water occurred 3 d post-challenge for both PCR and traditional culture techniques; however, a greater proportion of tanks were positive for F. columnare by PCR detection. In a second experiment, fingerlings were challenged by immersion bath. F. columnare was detected in water by PCR and culture techniques 1 and 2 d post-challenge, respectively. In both experiments, PCR detection in tissues was superior to traditional ...

He said the bacterial disease naturally occurs in fish and affects them in the spring of the year when they are undergoing some stress from spawning.. In a normal spring, the DNR sees the disease growing on fish in mid-May to mid-June. Wolter said with this years early spring and warmer than normal water temperatures, the disease started earlier and has killed more fish than normal.. "This year it just seems a little more severe," he said.. Taking a walk along the Detroit Lakes beach, Wolter said he saw "98 to 99 percent dead sunfish, with an occasional bass, bullhead or crappie," washed up dead. The windy days have pushed the dead fish up on the beach and shoreline of Little Detroit Lake. The die-off is usually a small percentage of the fish population. ...
Say you go to the hospital because your appendix has ruptured. This is a routine surgery that shouldnt take much time or effort. But being in the hospital puts you at risk for infection, especially when you are in the process of recovering from a routine, but intensive, procedure. If the infection is rare, it will take your doctor a longer time to identify the culprit. If the infection is resistant to common treatments, you will have to endure more extensive treatment programs. If you are recovering from a surgical procedure, or have other open and exposed wounds, youre immune system may be otherwise preoccupied. So, a short hospital stay that should have been routine, might end up being more extensive, or putting you at a higher risk for death. ...

July 1, 2009 By John Stossel. President Obama says government will make health care cheaper and better. But theres no free lunch.. In England, health care is free -- as long as you dont mind waiting. People wait so long for dentist appointments that some pull their own teeth. At any one time, half a million people are waiting to get into a British hospital. A British paper reports that one hospital tried to save money by not changing bedsheets. Instead of washing sheets, the staff was encouraged to just turn them over.. Obama insists he is not trying to bring about government-run healthcare.. But government management does the same thing, says Sally Pipes of the Pacific Research Institute. To reduce costs theyll have to ration -- deny -- care.. People line up for care, some of them die. Thats what happens, says Canadian doctor David Gratzer, author of The Cure. He liked Canadas government health care until he started treating patients.. The more time I spent in the Canadian ...

Flavobacterium columnare is the causative agent of columnaris disease, a disease affecting many freshwater fish species. Methods for the genetic manipulation for some of the species within the Bacteroidetes, including members of the genus Flavobacterium, have been described, but these methods were not adapted to work with F. columnare. As a first step toward developing a robust set of genetic tools for F. columnare, a protocol was developed to introduce the E. coli - Flavobacterium shuttle vector pCP29 into F. columnare strain C#2 by conjugal mating at an efficiency of 1.5 × 10-3 antibiotic-resistant transconjugants per recipient cell. Eight of eleven F. columnare strains tested were able to receive pCP29 using the protocol. pCP29 contains the cfxA and ermF genes, conferring both cefoxitin and erythromycin resistance to recipient cells. Selection for pCP29 introduction into F. columnare was dependent on cfxA, as ermF was found not to provide strong resistance to erythromycin. This is in contrast to
This study was conducted to evaluate the potential pathogenicity of the bacterium Flavobacterium columnare on rainbow trout Oncorhynchus mykiss eyed eggs. Survival to hatching was unaffected by the inclusion in the incubation water of either 300 colony-forming units (CFU) ml−1 or 3000 CFU ml−1 of F. columnare at either 10 or 12° C in either McConaughy or Shasta strain eyed eggs. Bacterial numbers, obtained via scanning electron microscopy or culture, and external membrane morphology were also not significantly different among eggs receiving different concentrations of F. columnare. Initial F. columnare burdens were significantly and positively correlated to the presence of biofilm on the egg external membrane, and biofilm was in turn significantly correlated with increased membrane degradation. The use of either streptomycin or tetracyclin antibiotics significantly reduced bacterial numbers on McConaughy strain eggs, and more eggs survived to hatch in those dishes treated with antibiotics ...
Flavobacterium columnare is a thin Gram-negative rod bacterium of the genus Flavobacterium. The name derives from the way in which the organism grows in rhizoid columnar formations. The species was first described by Davis (1922), and the name was validated by Bernardet and Grimont (1989). F. columnare can be identified in the laboratory by a five-step method that demonstrates: the ability to grow on a medium containing neomycin and polymyxin B production of yellow pigmented rhizoid (root-like in appearance) colonies production of a gelatin-degrading enzyme binding of Congo red dye to the colony production of a chondroitin sulfate-degrading enzyme The species has been known previously as Flexibacter columnaris, Bacillus columnaris, and Cytophaga columnaris. F. columnare is one of the oldest known diseases among warm-water fish, and manifests itself as an infection commonly known as columnaris. Infections are the second leading cause of mortality in pond raised catfish in the southeastern United ...
Ornithobacterium rhinotracheale (ORT) is a emerging gram negative bacterial pathogen in poultry. To facilitate the development of novel infection intervention and prevention strategies, the pathogenesis of ORT infection was investigated. In vitro infection assays demonstrated that ORT adhered to epithelial cells in a dose-dependent fashion. Comparison of the adhesive properties ... read more of different strains indicated that strain 41 lacked the ability to infect epithelial cells. This strain gained an adhesive phenotype when it was grown in suspension rather than on a solid phase medium. Bacterial adherence was inhibited in the presence of purified lipopolysaccharide (LPS). ORT also adhered to and became ingested by chicken and murine macrophages. This interaction was not blocked by LPS. The macrophage response to ORT was investigated using the production of nitric oxide (NO) as a marker. ORT induced the production of NO by macrophages. This stimulation did not require but was enhanced by ...
Flavobacterium psychrophilum causes bacterial cold-water disease (BCWD) in farmed rainbow trout (Oncorhynchus mykiss), with the multilocus sequence typing (MLST) clonal complex (CC) CC-ST10 accounting for the majority of outbreaks globally. The development of alternative strategies to antibiotic treatment of BCWD using bacteriophage-based control of F. psychrophilum, or virulence factors as targets for therapy, requires knowledge of the phage-sensitivity of outbreak strains and of universal traits contributing to their pathogenicity. To examine the association between virulence and both genetic (MLST sequence type (ST) and PCR-serotype) and phenotypic characteristics (adherence, antibiotic resistance, colony spreading motility, hemolytic and proteolytic activity), the median lethal dose (LD50) of 26 geographically disparate F. psychrophilum isolates was determined in rainbow trout. Furthermore, the in vitro sensitivity of the isolates against five bacteriophages was determined by the efficiency ...
The fight against rainbow trout fry syndrome The research is centered on the fish pathogenic bacterium Flavobacterium psychrophilum, which is the cause of rainbow trout fry syndrome (RTFS) in rainbow trout on Danish fish farms.. The areas of interest are characterization of virulence using biochemical, serological, genotyping and infection methods. The research focuses on the mechanisms by which the bacterium causes disease in rainbow trout, i.e. the pathogenesis (how the disease is progressing), the transmission (transfer to and between fish), and the survival of the bacteria, e.g. on as well as inside fish.. The researchers are involved in several projects on the bacterium Flavobacterium psychrophilum, amongst others the EMIDA project Pathofish where the objectives are to develop rapid methods for the detection of RTFS as well as vaccines. The researchers are furthermore involved in a project supported by the Danish AgriFish Agency - an agency under the Ministry of Food, Agriculture and ...
Recent studies evaluated that immunoproteomic vaccines provide protection against bacterial infections in fish aquaculture and the vaccines are popular due to its long lasting immunity, safety and low cost versatile characteristics. In this study we used Whole cell - Formalin Killed (WC) and Outer Membrane Protein (OMP) of F. Columnare as a vaccine to provide protection against columnaris disease in fish Catla catla. We used the extract of Asparagus racemosus as an adjuvant in the vaccine preparation. Survival of the vaccinated fishes (30 and 60 days post vaccination (dpv)), were evaluated after challenge with virulent F. columnare. The results showed that the relative percentage of survival in the catla fish groups vaccinated by Outer Membrane Protein (OMP) vaccine with adjuvtant were significantly higher than that the other types of vaccines (92%). The vaccine treated experimental groups significantly improved (P,0.05) the survival at 50% compared to the controls.. ...
The immune response in rainbow trout fry against Flavobacterium psychrophilum was elucidated using an immersion-based challenge with or without prior exposure to hydrogen peroxide (H2O2). Samples were taken from the head kidney 4, 48, 125 and 192 h after immersion, and the regulation of several genes was examined. Bacterial load was assessed based on the presence of 16S rRNA and correlated with gene expression, and the levels of specific antibodies in the blood were measured 50 days post-infection. Separately, both H2O2 and F. psychrophilum influenced gene expression, and pre-treatment with H2O2 influenced the response to infection with F. psychrophilum. Pre-treatment with H2O2 also affected correlation between gene regulation and pathogen load for several genes. A delay in antibody production in H2O2-treated fish in the early phase of infection was indicated, but H2O2 exposure did not affect antibody levels 50 days post-infection. An increasing amount of F. psychrophilum 16S rRNA was found in ...
Posted 03/18/2011]. ISSUE: H&P industries, Inc., a manufacturer of over-the-counter products, initiated a voluntary product recall of ALL LOTS of Povidone Prep Pads manufactured by H&P Industries, Inc. but which are private labeled for many accounts.

A bacterial strain (CC-TWGS1-8T) isolated from a tar-contaminated soil in Taiwan was studied in a detailed taxonomic study. The cells were Gram-negative, rod-shaped and non-spore-forming. Phylogenetic analyses using the 16S rRNA gene sequence of the strain clearly revealed an affiliation to the genus Chryseobacterium, the highest sequence similarities being to the type strain of Chryseobacterium indologenes (96·8 %), to Chryseobacterium gleum (96·8 %) and to Chryseobacterium joostei (96·4 %). The 16S rRNA gene sequence similarities to all other Chryseobacterium species were below 96 %. The major whole-cell fatty acids were 15 : 0 iso (35·4 %) and 17 : 0 iso 3OH (22·5 %). DNA-DNA hybridization values and the biochemical and chemotaxonomic properties demonstrate that strain CC-TWGS1-8T represents a novel species, for which the name Chryseobacterium taichungense sp. nov. is proposed. The type strain is CC-TWGS1-8T (=CCUG 50001T=CIP 108519T).

Interpretive Summary: A rapid bioassay was used to evaluate extracts from the stem bark of plant found in Kenya for antibacterial activities against fish pathogenic bacteria. Two natural compounds were isolated from the extracts and discovered to possess antibacterial activities against a species of fish pathogenic bacteria which causes a common disease in pond-raised catfish and several other species of freshwater fish.. Technical Abstract: The pond-raised channel catfish (Ictalurus punctatus) industry in the United States of America can incur losses of over a $100 million annually due to bacterial diseases including columnaris disease caused by Flavobacterium columnare. One management approach available to catfish producers is the use of medicated-feed containing antibiotics. However, the negative attributes of antibiotic use in agriculture include public concerns and the potential development of antibiotic-resistant bacteria. Therefore, the discovery of environmentally-safe natural compounds ...
Riemerella anatipestifer has been a problematic pathogen of commercial importance for several years and it is hard to give the correct treatment measures. One possible reason is poor cross immune protection among various serotypes; another important reason may be due to the similarity of clinical symptom between R. anatipestifer infection and E. coli infection. In recent years, R. anatipestifer strains with reduced susceptibility to antimicrobials have emerged as reported in others study and our previous investigation [8, 23] because of the use of antimicrobials in animals, which reflects the necessity of searching for new compounds or strategies to treat Riemerella anatipestifersis [8, 10, 23]. Maintaining the utility of antimicrobials in treating Riemerella anatipestifersis seems to be a major challenge. As proposed by other researchers, one of the strategies to tackle the resistance problem is to reduce or prevent the emergence of resistant mutants [19]. In human medicine, MPC values and ...
Repeated laboratory passage of pathogens in the presence of rifampicin has been used to generate live-attenuated vaccines [1, 7-12], but the mechanism of rifampicin-induced attenuation remains unknown. There are a variety of potential confounding factors with this type of passage experiment that make cause-and-effect interpretations challenging. Passage can produce changes in global protein expression profiles [12, 13] or altered lipopolysaccharide (LPS) biosynthesis/colony roughness [7]. These changes could be attributed to altered activity of RpoB in the Rif resistant DNA-dependent RNA polymerase (RNAP) present in rifampicin resistant bacteria [14]. That is, the presence and activity of the mutated rpoB is one hypothesis for the mechanism of attenuation. Alternatively, rifampicin-associated attenuation may result from accumulation of spontaneous mutations acquired in the course of in vitro passaging. Serial passage of a pathogenic bacterium without any antibiotics can also induce changes in ...

A patient with cystic fibrosis became chronically colonised with an unusual non-fermenting Gram-negative rod that could be cultured on Burkholderia cepacia selective agar. Phenotypic characterisation by VITEK-2 suggested identification as Elizabethkingia meningoseptica, however 16S rRNA gene sequencing revealed it belonged to a putative novel species of genus Dyella. Thirty months after the initial detection, the patient produced a high level of precipitating antibodies against the bacterium ...
This experiment was conducted to evaluate the effects of Ornithobacterium rhinotracheale (ORT) infection on oxidative stress and the activity of antioxidant enzymes in blood, trachea and lung tissues of broilers. Broiler chickens were divided into 2 groups, each consisting of 30 animals. Group 1 was used as control group; Group 2 was used as infection group. The 2nd group was infected by aerosol route with 1 mL of a pure culture of ORT strain B3263/91 (serotype A) containing 3.8x108 CFU mL-1. At the end of the experiment blood and tissue samples were collected and biochemical parameters were determined. While, plasma Malondialdehyde (MDA) and Nitric Oxide (NO) levels were increasing at infection group than control group, erythrocyte Catalase (CAT) and Glutathione Peroxidase (GSH-Px) activities were decreasing in accordance with control group. Levels of MDA and NO in trachea tissue increased at infection group more than control group; but activities of CAT and GSH-Px did not change. MDA level and ...
The survey results cover experience from August 2015 through August 2016 and are based on responses from 21 veterinarians and other professionals representing the US turkey industry, Dr Clark reported.. A shortage of approved, effective medications has been the top health issue for the US turkey industry for years. Other problems high on the list of health issues cited by respondents in the latest survey include colibacillosis, clostridial dermatitis (cellulitis), Ornithobacterium rhinotracheale (ORT) and leg problems.. Clostridial dermatitis, Dr Clark noted, remains a major disease issue across all geographic regions and is most often seen in commercial male turkeys nearing market age. Mortality in affected flocks is greater than or equal to 0.5 dead per 1,000 birds.. The highly contagious bacterial respiratory disease ORT was a major cause of respiratory disease in Midwestern states in 1995 but has since become endemic across most of the US, he said.. In a previous survey, leg problems ranked ...

The post-vitellogenic oocytes of teleost fish are generally unresponsive to maturation-inducing hormone (MIH) until a luteinizing hormone (LH) surge stimulates sensitivity via the acquisition of oocyte-maturational competence (OMC). Heterologous gap junctions (GJs) between granulosa cells and the oocyte have been previously implicated in the regulation of oocyte maturation in various vertebrate species. Although heterologous GJ are present in ovarian follicles of ayu (Plecoglossus altivelis), their role in maturation remains unclear. In the present study, we cloned and characterized complementary DNAs for GJ protein connexin (Cx), and examined the expression pattern of Cx messenger RNAs in the ayu ovary. Four Cx cDNAs with predicted molecular masses of 32.1 (Cx32.1), 34.9 (Cx34.9), 44.1 (Cx44.1), and 44.2 (Cx44.2) kDa, respectively, were cloned. Northern blot analysis revealed that the levels of Cx44.1 and Cx44.2 transcripts were similar during the vitellogenic and ovulatory stages. Cx32.1 transcripts

treatment 5, and feed conversion ratios (FCR) ranged from 1.15 in treatment 5 to 1.51 in treatment 2. No significant differences, in average weight and FCR were observed between any of the treatments. Mean survival ranged from 47.5 % in treatment 2 to 73.4 % in treatment 5. Significant differences were observed between treatment 2 (47.5 %) and the other three treatments as well as between treatment 3 (60.7 %) and treatment 5 (73.4 %). Mean observed mortality ranged from 1.5 % in treatment 5 to 6.8 % in treatment 2, no significant differences were observed between any of the treatments. In the laboratory study, mortality ranged from 8 % in treatment 4 to 19.9 % in treatment 2. No statistical differences were observed between any of the treatments. The proper evaluation of the vaccine was difficult because the presence of mixed infections of ESC and Columnaris disease made it impossible to determine which of the two diseases was responsible for the mortality of fish collected during a documented ...

Most microbial pathways have existed for a very long time, many since the existence of the very first microbe. Fermentation, substrate-level phosphorylation, and oxidization of complex sugars are just a few of the common processes that occur daily inside of countless microbes. These processes, and their associated enzymes, have been found proceeding inside of many samples of bacteria. However, there are rare cases when traditional processes are altered or even completely rearranged. Even more rare, such as in the case of F. Sp. K172, unique biological processes are sometimes found.. It is important to understand the common occurrences of Flavobacterium before discussing the uniqueness of Sp. K172. Flavobacterium is a genus of bacilli bacteria that are gram-negative. These bacteria tend to live in fresh water sources, but are quite common in many types of damp soil as well. Species of Flavobacterium often cause disease in fish living in the same water source. Most Flavobacterium produce very ...
