Fig. 4. Multilocus sequence typing analysis of bacteria presumed to be V. parahaemolyticus and other Vibrionaceae isolates. The phylogenetic tree was produced using the Jukes-Cantor model, with complete deletion of gaps and missing data, use of 1,000 bootstrap replicates, and the gamma 2.0 correction calculated using MEGA 3.1. Isolates are identified in a sample date code (e.g., the first sampling in May 2007 is 05071), followed by location (in a creek at high tide [H], ebb tide [E], low tide [L], or flood tide [F]; in a burrow in tall Spartina [TB], short Spartina [SB], and Juncus [JB]; and in pore water in tall Spartina [TP], short Spartina [SP], and Juncus [JP]) and isolate number. Asterisks indicate isolates presumed not to be V. parahaemolyticus. ...

Of all concerns which face the shellfish industry, none are currently as critical as the presence of Vibrio vulnificus in oysters. In fact, 95% of all deaths resulting from seafood consumption are caused by this bacterium (8). V. vulnificus is part of the normal bacterial flora of estuarine waters and occurs in high numbers in molluscan shellfish. Fatality rates of over 60%, with median incubation times to onset of symptoms being as low as 7 h, have been reported (8). Between 1989 and 2000, 274 cases involving oyster ingestion occurred in the United States, of which 142 (52%) were fatal. Most (∼95%) cases occur in individuals who are immunocompromised, have diabetes, or have underlying diseases/syndromes which result in elevated serum iron levels, primarily liver cirrhosis secondary to alcohol abuse/alcoholism (7). Additionally, most (∼95%) cases occur in males, since females are protected from the V. vulnificus endotoxin by estrogen (5). Recent evidence also suggests that only certain ...

The occurrence of arbuscular mycorrhizal fungi (AMF) was assessed by both morphological and molecular criteria in two salt marshes: (i) a NaCl site of the island Terschelling, Atlantic Coast, the Netherlands and (ii) a K2CO3 marsh at Schreyahn, Northern Germany. The overall biodiversity of AMF, based on sequence analysis, was comparably low in roots at both sites. However, the morphological spore analyses from soil samples of both sites exhibited a higher AMF biodiversity. Glomus geosporum was the only fungus of the Glomerales that was detected both as spores in soil samples and in roots of the AMF-colonized salt plants Aster tripolium and Puccinellia sp. at both saline sites and on all sampling dates (one exception). In roots, sequences of Glomus intraradices prevailed, but this fungus could not be identified unambiguously from DNA of soil spores. Likewise, Glomus sp. uncultured, only deposited as sequence in the database, was widely detected by DNA sequencing in root samples. All attempts to ...

2 with target DNA displayed only 2.8% false positives. The prototype microarray was subsequently tested with an environmental sample, which consisted of an Agrobacterium-related polymerase chain reaction amplicon from a maize rhizosphere bacterial community. Microarray results were compared to results obtained by cloning-sequencing with the same DNA. Microarray analysis enabled the detection of all 16S rRNA gene sequences found by cloning-sequencing. Sequences representing only 1.7% of the clone library were detected. In conclusion, this prototype 16S rRNA-based taxonomic microarray appears to be a promising tool for the analysis of Alphaproteobacteria in complex ecosystems.>.

We recently held a workshop that brought together, perhaps for the first time, researchers in the fields of atmospheric and indoor air chemistry, infection control engineering, building physics, and environmental microbiology. As separate groups of scientists, we tend to focus on discipline-specific problems. Indoor air chemists are largely concerned with chemical reactions indoors and the resulting products and then trying to identify those that may be harmful to health. Members of the indoor biological community, on the other hand, are interested in airborne microorganisms and often work at the frontline of pathogen control. For instance, they may be trying to eliminate infectious agents from a hospital environment, where compromised immunities make some occupants much more susceptible to infection.. Both communities advocate for good ventilation. The expanding desire to make buildings more energy efficient, combined with greater knowledge of the composition of our indoor air, has, in recent ...

Gram staining is a bacteriological laboratory technique[4] used to differentiate bacterial species into two large groups (gram-positive and gram-negative) based on the physical properties of their cell walls.[5][page needed] Gram staining is not used to classify archaea, formerly archaeabacteria, since these microorganisms yield widely varying responses that do not follow their phylogenetic groups.[6] The Gram stain is not an infallible tool for diagnosis, identification, or phylogeny, and it is of extremely limited use in environmental microbiology. It is used mainly to make a preliminary morphologic identification or to establish that there are significant numbers of bacteria in a clinical specimen. It cannot identify bacteria to the species level, and for most medical conditions, it should not be used as the sole method of bacterial identification. In clinical microbiology laboratories, it is used in combination with other traditional and molecular techniques to identify bacteria. Some ...

Abstract: We hypothesized that interactions between fusarium head blight-causing pathogens and herbivores are likely to occur because they share wheat as a host plant. Our aim was to investigate the interactions between the grain aphid, Sitobion avenae, and Fusarium graminearum on wheat ears and the role that host volatile chemicals play in mediating interactions. Wheat ears were treated with aphids and F. graminearum inoculum, together or separately, and disease progress was monitored by visual assessment and by quantification of pathogen DNA and mycotoxins. Plants exposed to both aphids and F. graminearum inoculum showed accelerated disease progression, with a 2-fold increase in disease severity and 5-fold increase in mycotoxin accumulation over those of plants treated only with F. graminearum. Furthermore, the longer the period of aphid colonization of the host prior to inoculation with F. graminearum, the greater the amount of pathogen DNA that accumulated. Headspace samples of plant ...

报告人简介：. Professor, Department of Microbiology and Molecular Genetics, University of California, Davis,. Editor for Applied and Environmental Microbiology（AEM）. 报告摘要：. Motile bacteria have the ability tosampletheir environment and detect and move toward available growth substrates using a process called chemotaxis. Many soil bacteria are capable of degrading a wide variety of organic compounds including toxic pollutants and man-made chemicals. Chemotaxis can increase the efficiency of the biodegradation process. The most common sensory proteins used for bacterial chemotaxis are cell-surface receptors called methyl-accepting chemotaxis proteins, and the genomes of soil bacteria often harbor up to 60 chemoreceptor genes. P. putida is chemotactic to most substrates on which it is capable of growth, and it uses several different strategies to detect potential growth substrates. In this presentation it will be described and discussed that the different types of ...

Experience in conducting soil surveys and ...

Microorganisms present in sauerkraut, including those of the lactobacillus bacteria genus, essentially feed the good bacteria in your gut, which improves digestive health. Research shows that within sauerkraut, Lactobacillus plantarum is the predominant LAB bacteria strain thats born during the fermentation phase. (7). We have a lot to learn about the exact types of beneficial bacteria that grow within cultured foods, but for the first time, a 2003 report published in The Journal of Applied Environmental Microbiology demonstrated the complex ecology present in sauerkraut fermentations. (8). As they can help lower the presence of toxins, inflammation and bad bacteria living within your digestive tract, probiotics bacteria are beneficial for reducing symptoms like irritable bowel syndrome (IBS), constipation, diarrhea, bloating, food sensitives and digestive disorders. (5). We often hear that probiotic yogurt is one of the best foods to eat for better digestion and preventing illnesses, but ...

Jack Gilbert, a microbiologist at Argonne National Laboratory in Illinois, is co-author of a 2014 study in the journal of Applied and Environmental Microbiology in which researchers tracked the microbiomes of four university restrooms over hours and days. According to LiveScience, Gilbert and his colleagues first sampled restrooms on an hourly basis and then sterilized the locations to start with a clean slate. They then allowed 4 more hours use and then shut the bathrooms down for the rest of the day to see how the bacterial assortment changed with time. People bring a lot of bacteria into bathrooms, the researcher found. LiveScience reported that within an hour of normal use, there were 500,000 bacterial cells per square inch on the bathroom surfaces, on average. But when left undisturbed, many of these bacteria quickly perished. Gut bacteria, especially, which dont do well tolerating oxygen, cold or lack of nutrients, did very poorly, Gilbert said, according to LiveScience. Skin bacteria ...

Home design and décor is comprised of countless materials and textures, but only one boasts the ability to ward off bacteria. Copper is quickly becoming one of the more popular elements in home decor as word of its health benefits continues to spread.. According to Applied and Environmental Microbiology, metallic copper surfaces kill microbes on contact. While researchers and scientists are examining the impact this can have in hospitals and group living facilities, designers and homeowners are embracing its green, healthy, and stylish benefits.. The warm tones of copper can be integrated into subtle-yet eye-catching features of fireplaces, backsplashes, and accent walls. But to best take advantage of its antimicrobial benefits, install copper hardware (door and cabinet handles), faucets, sinks, countertops, and railings.. ...

CORVALLIS, Ore. - Corals that appear healthy are more prone to getting sick when theyre home to too many parasitic bacteria, new research at Oregon State University shows.. Supported by the National Science Foundation, the study, published in Environmental Microbiology, adds fresh insight to the fight to save the Earths embattled coral reefs, particularly those in the Caribbean.. The clear relationship weve discovered between this kind of bacteria and disease resistance in Caribbean staghorn coral is a crucial piece of the puzzle for coral restoration efforts in that region, said study co-author Becca Maher, a Ph.D. candidate at Oregon State.. Found in less than 1% of the ocean but home to nearly one-quarter of all known marine species, coral reefs help regulate the seas carbon dioxide levels and are a crucial hunting ground that scientists use in the search for new medicines.. Between 2014 and 2017, more than 75% of the worlds reefs experienced bleaching-level heat stress, and 30% ...

You can still sort of smell it now, cant you? Because chronic bad breath is pretty evil - the result of persistent oral microbes and their metabolic waste, especially the volatile sulfur compounds they produce (the stuff that makes rotten eggs smell so rotten). And as we noted before, research published in Applied and Environmental Microbiology has shown that its not just a matter of bacterial overgrowth due to poor oral hygiene. In fact, its not just the type of bacteria that matters but the balance of oral flora.. The trick in stopping or at least controlling bad breath involves maintaining that balance. And just as there are many things that can cause it to get out of whack, there are many things you can do to make sure it doesnt.. Recently, Dr. Margaret Mitchell of Chicagos Mitchell Dental Spa sent out a tip sheet that makes for a pretty good guide to keeping the bad out of your breath. So here are their 10 easy tips for keeping bad breath at bay, edited for length and clarity, ...

Applied and Environmental Microbiology. 75(10):3029-3033. Interpretive Summary: To understand how sporadic outbreaks of vesicular stomatitis occur in cattle and horses in the western U.S. we must understand which insect vectors are important in amplifying, maintaining, and transmitting the virus to these animals. Migratory grasshoppers have been implicated as reservoirs and mechanical vectors of VSV. The grasshopper-cattle-grasshopper transmission cycle is based on the assumptions that 1) virus shed from clinically infected animals would contaminate pasture plants and remain infectious on plant surfaces, and 2) grasshoppers would become infected by eating the virally contaminated plants. Our objectives were to determine the stability of VSV on common plant species of U.S. Northern Plains rangelands, and ...

There has been increasing concern about the impacts of exposure to chemical compounds with endocrine disrupting activi- ties in the environment, especially aquatic environments, to wildlife and humans. South Africa is known to have used and abused most chemicals listed by developed and developing countries as endocrine-disrupting chemicals. Endocrine- disrupting chemicals have been reported in water, sediment and serum, as well as in fish tissue samples, at a level that could trigger endocrine disruption in humans and wildlife. Although some monitoring has been reported, particularly in water systems within the country, information on EDCs in other environmental matrices is scanty. The water systems monitored so far are very few. The strongest economy in Africa, and an emerging world economy depending on agriculture, mining, manufacturing and industry, needs to focus more on monitoring and to strengthen government organs and institutions to monitor and ensure environmental safety ...

Perchlorate is a synthetic chemical that is used in the manufacture of rocket fuel, fireworks, flares and explosives, and can also be present in bleaches and some fertilizers [1]. The EPA has devised drinking water regulations for Perchlorate to minimize its impact on human health and the environment.. Achieving lower analytical detection limits for Perchlorate in environmental matrices such as drinking water allows regulatory bodies like the EPA make better informed decisions on the degree of contamination of an environmental system, as well as the remedial actions required to limit adverse health and environmental effects.. The expression Compact Mass Spectrometer (CMS) provides lower detection limits and greater selectivity for Perchlorate compared to a conductivity detector (CD). The typical detection limit of a CD is in the mid to high-ppb range, the CMS can detect , 20 ppt.. ...

Indirect transmission between humans via environmental surfaces may play a role in infections, but methods to investigate this have been sparse. |br||br|Kit used: FTD Viral gastroenteritis |br||A HREF=http://www.journalofhospitalinfection.com/article/S0195-6701(16)00036-0/abstract target=_blank|Website link|/A|

The only sampling site in the German middle course of the river Danube. It forms a bridgehead over the Rhine-Main-Danube Canal to the river Rhine.

A new Enzyme ImmunoAssay (EIA) for PCDD/F TEQ measurement in extracts of environmental samples was described. The bioassay TEQ which derived from EIA and EROD were compared with each other and with results from chemical analysis. For all environmental samples, the EROD-TEQ is higher than the value from chemical analysis. However, the EIA-TEQ is much more identical with the value from chemical analysis. Our results indicate that the EIA assay is a complementary method to the EROD assay and should be useful as a rapid and sensitive screening tool for environmental samples in many situations.

The PhyloChip wins bronze at The 2008 WSJ Technology Innovation Awards.. During the selection process for these awards, the ESD team continued to find new applications for the PhyloChip. ESD post-doc Kristin DeAngelis selected the PhyloChip to pinpoint 147 soil bacteria responding to root growth from native California grasses. It turns out that this is a relatively small subset (only 7%) of the entire bacterial community. DeAngelis also compared the PhyloChip-generated data against an older, more laborious technique, T-RFLP, and found that while the two agreed well on the subset percentage, only the PhyloChip enabled identification of the taxa in flux. Her article will be presented in the Nature publication, International Society of Microbial Ecology Journal (ISME). ISME will also publish the results of an international effort to discover the bacteria and archaea inhabiting the extreme environments in Antarctica. The research team opted for the PhyloChip after the costly method of DNA sequencing ...

This is a comprehensive course that unifies sociology with business management. This is to be realized by explaining and demonstrating how and why various environments and its institutions influence the behavior of organizations and people working in them, in both theory and practice. The dimensions of environments to be discussed entail socio-cultural, socio-economic, political, legal and labor dimensions. Organizational dimensions will entail organizational and individual level concepts such as organization culture, leadership, conflicts, teams and motivation. As a learning outcome, students will develop a Project in which they will analyze different environmental factors and identify and explain their influence and the effects of such influence to organizational and individual level behaviors ...
