One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

Influence of crossdrafts on the performance of a biological safety cabinet. (1/924)

A biological safety cabinet was tested to determine the effect of crossdrafts (such as those created by normal laboratory activity or ventilation) upon the ability of the cabinet to protect both experiments and investigators. A simple crossdraft, controllable from 50 to 200 feet per min (fpm; 15.24 to 60.96 m/min), was created across the face of the unit. Modifications of standardized procedures involving controlled bacterial aerosol challenges provided stringent test conditions. Results indicated that, as the crossflow velocities exceeded 100 fpm, the ability of the cabinet to protect either experiments or investigators decreased logarithmically with increasing crossdraft speed. Because 100 fpm is an airspeed easily achieved by some air conditioning and heating vents (open windows and doorways may create velocities far in excess of 200 fpm), the proper placement of a biological safety cabinet within the laboratory--away from such disruptive air currents--is essential to satisfactory cabinet performance.  (+info)

How a fungus escapes the water to grow into the air. (2/924)

Fungi are well known to the casual observer for producing water-repelling aerial moulds and elaborate fruiting bodies such as mushrooms and polypores. Filamentous fungi colonize moist substrates (such as wood) and have to breach the water-air interface to grow into the air. Animals and plants breach this interface by mechanical force. Here, we show that a filamentous fungus such as Schizophyllum commune first has to reduce the water surface tension before its hyphae can escape the aqueous phase to form aerial structures such as aerial hyphae or fruiting bodies. The large drop in surface tension (from 72 to 24 mJ m-2) results from self-assembly of a secreted hydrophobin (SC3) into a stable amphipathic protein film at the water-air interface. Other, but not all, surface-active molecules (that is, other class I hydrophobins and streptofactin from Streptomyces tendae) can substitute for SC3 in the medium. This demonstrates that hydrophobins not only have a function at the hyphal surface but also at the medium-air interface, which explains why fungi secrete large amounts of hydrophobin into their aqueous surroundings.  (+info)

Contaminations occurring in fungal PCR assays. (3/924)

Successful in vitro amplification of fungal DNA in clinical specimens has been reported recently. In a collaboration among five European centers, the frequency and risk of contamination due to airborne spore inoculation or carryover contamination in fungal PCR were analyzed. The identities of all contaminants were specified by cycle sequencing and GenBank analysis. Twelve of 150 PCR assays that together included over 2,800 samples were found to be contaminated (3.3% of the negative controls were contaminated during the DNA extraction, and 4.7% of the PCR mixtures were contaminated during the amplification process). Contaminants were specified as Aspergillus fumigatus, Saccharomyces cerevisiae, and Acremonium spp. Further analysis showed that commercially available products like zymolyase powder or 10x PCR buffer may contain fungal DNA. In conclusion, the risk of contamination is not higher in fungal PCR assays than in other diagnostic PCR-based assays if general precautions are taken.  (+info)

Density and molecular epidemiology of Aspergillus in air and relationship to outbreaks of Aspergillus infection. (4/924)

After five patients were diagnosed with nosocomial invasive aspergillosis caused by Aspergillus fumigatus and A. flavus, a 14-month surveillance program for pathogenic and nonpathogenic fungal conidia in the air within and outside the University Hospital in Rotterdam (The Netherlands) was begun. A. fumigatus isolates obtained from the Department of Hematology were studied for genetic relatedness by randomly amplified polymorphic DNA (RAPD) analysis. This was repeated with A. fumigatus isolates contaminating culture media in the microbiology laboratory. The density of the conidia of nonpathogenic fungi in the outside air showed a seasonal variation: higher densities were measured during the summer, while lower densities were determined during the fall and winter. Hardly any variation was found in the numbers of Aspergillus conidia. We found decreasing numbers of conidia when comparing air from outside the hospital to that inside the hospital and when comparing open areas within the hospital to the closed department of hematology. The increase in the number of patients with invasive aspergillosis could not be explained by an increase in the number of Aspergillus conidia in the outside air. The short-term presence of A. flavus can only be explained by the presence of a point source, which was probably patient related. Genotyping A. fumigatus isolates from the department of hematology showed that clonally related isolates were persistently present for more than 1 year. Clinical isolates of A. fumigatus obtained during the outbreak period were different from these persistent clones. A. fumigatus isolates contaminating culture media were all genotypically identical, indicating a causative point source. Knowledge of the epidemiology of Aspergillus species is necessary for the development of strategies to prevent invasive aspergillosis. RAPD fingerprinting of Aspergillus isolates can help to determine the cause of an outbreak of invasive aspergillosis.  (+info)

Microscopic fungi in dwellings and their health implications in humans. (5/924)

The article reviews the quantitative and qualitative incidence of microscopic filamentous fungi in dwellings, methods for their detection, mycotoxins, glucans and volatile organic compounds produced by microscopic fungi in the indoor air of homes. Characteristics and properties of the most important species of fungi in dwellings (Alternaria spp., Aspergillus spp., Cladosporium spp., Fusarium spp., Penicillium spp., Stachybotrys spp., and Wallemia spp.) and the health problems of occupants of the "moldy homes are also discussed.  (+info)

Exposure to airborne microorganisms and volatile organic compounds in different types of waste handling. (6/924)

Occupational exposure of workers to airborne microorganisms and volatile organic compounds (VOC) in different types of waste treatment situations was examined during summer time. Microorganisms were collected as stationary samples using a six-stage Andersen impactor, while for VOCs both personal and stationary sampling was conducted. The exposure at the waste handling facility was considerably greater than at landfill sites or in waste collection. The concentrations of viable fungi were maximally 10(5) cfu/m3, and the concentrations of both total culturable bacteria and Gram-negative bacteria exceeded the proposed occupational exposure limit values (OELV), being 10(4) and 10(3) cfu/m3, respectively. Exposure to VOCs in the waste handling facility was three times higher than at the landfill sites, being at highest 3000 microg/m3, considered to be the limit for discomfort. The use of personal protective equipment at work, thorough hand washing and changing clothes after the work shift are strongly recommended in the waste handling facility and the landfill sites.  (+info)

Application of the classic Limulus test and the quantitative kinetic chromogenic LAL method for evaluation of endotoxin concentration in indoor air. (7/924)

The classic (gel-clot procedure) Limulus test (CLT) and the quantitative kinetic chromogenic LAL method (KQCL) used for the evaluation of bacterial endotoxin concentration in the indoor air of dwellings were compared. The scientific procedure included analyses of 40 air samples supplemented by the analysis of 20 sample duplicates (selected at random) which were taken during the fall season from 10 flats located in 3 towns of the Upper Silesian region (southern Poland). The particulate aerosol probes were sampled by Harvard impactor and Casella sampler. The same samples were analyzed in the Netherlands using the quantitative kinetic chromogenic LAL method, and in Poland using the classic Limulus test. Comparison of both methods revealed that the quantitative kinetic chromogenic LAL method was more precise, with better reproducibility (the coefficient of variation between analyses of the main probe and its duplicate was over two times smaller in the KQCL method than in the CLT method), fully automated in the phase of analysis and data reading, and faster and more effective than the classic Limulus test. Nevertheless, on the basis of the obtained results, the usefulness of the classic Limulus method for assessment of the degree of pollution of indoor air with bacterial endotoxin seems to be confirmed as in the majority of examined samples (21 out 40) the results obtained by both methods were of the same order of magnitude, and in the remaining 19 samples did exceed one order of magnitude. Thus, the data received by means of the classic Limulus test may be regarded as acceptable.  (+info)

Risk of infection from heavily contaminated air. (8/924)

In a factory processing shea nuts the dust concentrations were found to be up to 145 mg/m3 [80% respirable (1--5 micrometer)]. Bacterial examination of the dust revealed that under the worst conditions observed a worker might inhale 350,000 bacteria per 8 h. Of these, 3,000 were Ps. aeruginosa and 1,500 Salmonella spp. of nine different types. The possible health effects of these findings are discussed.  (+info)

Viruses can become airborne through the release of contaminated liquids or dried material and can then be carried by air currents indoors, and outdoors. The methodology for generating, storing, and collecting viral aerosols has already been reviewed. Therefore, this chapter is focused on a critical review of the information on the role of air in the spread of vertebrate viruses. Work with airborne viruses also requires stringent safety precautions. In spite of the limitations, ultrafine threads are the best means to study the influence of atmospheric chemicals and light and irradiation on airborne viruses. According to Pike, 27% of the cases of laboratory-acquired infections were due to airborne viruses; cases in research settings accounted for more than 67% of such infections. Increasing use of recycled air will further enhance the risk of exposure of susceptible individuals to airborne viruses. Recently, alteration of the lung airway surface properties by spraying normal saline into the respiratory
In this report, a fully avian H7N1 virus was adapted to become capable of airborne transmission in ferrets. The virus also showed transmission to all CH animals, suggesting that transmission via direct contact was also enhanced; however, it is possible that airborne transmission could also occur in CH animals. The findings are consistent with those on the adaptation of highly pathogenic H5N1 (16), as no reassortment event was required to yield a virus capable of airborne transmission. In agreement with studies on H9N2 and H5N1, a limited number of amino acid mutations (five or six) were associated with airborne transmission and serial passage leads to mammalian adaptation (16, 25, 27). In the HA-encoding gene, we identified a single mutation present in all AC ferrets, resolution of K/R313R. This mutation is located in the stalk region of H7 HA. Thus, it is unlikely to influence receptor binding. The receptor-binding preference of WT H7N1 was previously characterized and shown to be consistent ...

By Amanda Makowiecki Miller Research Group University of Colorado, Boulder. With drug resistant bacteria becoming a growing problem, alternative methods are being pursued to decontaminate air and surfaces; ultraviolet germicidal irradiation (UVGI) is one of these methods. UVGI uses short wavelength light in order to disrupt the genetic material of microorganisms, this disruption either kills the microorganisms or prevents them from replicating, for further information on UVGI (http://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation). When considering that bacteria can acquire drug resistance, it is only logical to determine whether or not bacteria can develop UVGI resistance as well. Goldman and Travisano performed such a study on the development of UVGI resistance in E. coli cells, which were exposed to UVGI daily for 60 days.. This study used 24 samples from a parent E. coli strain, 12 of these samples were exposed to UVGI and 12 were held as a control group. The samples were grown on ...
Recent measurements identified SARS-Cov-2 RNA on aerosols in Wuhans hospitals (18) and outdoor in northern Italy (21), unraveling the likelihood of indoor and outdoor airborne transmission. Within an enclosed environment, virus-bearing aerosols from human atomization are readily accumulated, and elevated levels of airborne viruses facilitate transmission from person to person. Transmission of airborne viruses in open air is subject to dilution, although virus accumulation still occurs due to stagnation under polluted urban conditions (7, 22). Removal of virus-bearing particles from human atomization via deposition is strongly size dependent, with the settling velocities ranging from 2.8 × 10−5 m⋅s−1 to 1.4 × 10−3 m⋅s−1 for the sizes of 1 and 10 μm, respectively (7). For comparison, typical wind velocity is about 1 m⋅s−1 to 3 m⋅s−1 indoors (23) and is ∼1 m⋅s−1 horizontally and 0.1 m⋅s−1 vertically in stable air (7, 22). Under those indoor and outdoor conditions, ...
Objectives: This study was performed to assess based on field investigation the distribution characteristics of airborne fungi in an area of Seongdong-gu, Seoul. Methods: Three sites, a living area, forest and traffic site, were selected for evaluation of monthly level of outdoor airborne fungi. An on-site survey was executed between January 2009 and December 2009. During the experimental period, air sampling was performed every month in the afternoon (2:00 pm-5:00 pm) using a cascade impactor. Results: Outdoor airborne fungi measured in Seoul, Korea over one year showed a concentration range from 850CFU |TEX|$m^{-3}$|/TEX| to 15,200CFU |TEX|$m^{-3}$|/TEX|. The mean respirable fraction of outdoor airborne fungi was 67% compared to total concentration. Regardless of measurement site, there was no significant concentration difference in outdoor airborne fungi between periods of yellow dust and non-yellow dust (p|0.05). There was no significant correlation relationship between outdoor airborne fungi

Published: July 8th, 2009. Revised: January 23rd, 2019. Spore trap sampling involves collecting airborne particles on a filter membrane or adhesive-coated slide by drawing air through or over the collection medium, respectively. The collection medium is then analyzed by transmitted light microscopy, typically at 600-1000 × magnification. A number of different collection devices may be used for spore trap sampling of which the most common are 1) mixed cellulose ester membrane (MCEM) filters; and 2) slit impactors such as the Allergenco D or Air-O-Cell® cassette.. The normally high minute-to-minute variability in levels of airborne spores greatly limits the utility of short-term quantitative air sampling data. This large intrinsic source of variation also minimizes the importance of counting method as a significant source of error. The most critical source of error in spore trap analysis qualitative, involving the identification of spores. Spore trap analysis is one of the most technically ...

An international research study published last week in the journal Atmospheric Environment has found that re-suspended roadside soil dust is a major source of atmospheric lead in old inner city areas.
Airborne transmission of infectious diseases is a subject of increasing interest driven by a wide range of factors including: greater understanding of the role played by indoor air and ventilation provision in the dispersal and transport mechanisms of a wide range of pathogens; changing expectations of hospital patients, particularly in developed countries; and the emergence of new or drug-resistant disease strains with the potential to spread on a global scale. Tuberculosis (TB) is an archetypal example of a disease that is transmitted by a true airborne route; primary infection occurs when droplet nuclei containing Mycobacterium tuberculosis bacilli are inhaled. These tiny particles (typically ,5 µm in diameter) can remain suspended in the air for long periods of time with local airflow pathways inside a building determining their fate. TB is a particular concern as it is once again a worldwide health problem, compounded by the increased susceptibility to M. tuberculosis in HIV/AIDS patients, ...

Successful implementation of a USP ,797, environmental sampling program starts with an understanding of the different tests required by USP ,797,. The most basic division between the required tests is nonviable particle sampling and viable particle sampling. Nonviable airborne particle testing seeks to measure the density of airborne particles based strictly on their size (0.5 µm in diameter or larger) without regard for the nature of the particles themselves. Viable particle sampling only measures those particles that are living organisms (typically bacterial and fungal spores). USP ,797, breaks viable particle testing into several different categories, each of which is designed to test a separate aspect of pharmaceutical compounding for potential contamination. These tests are viable airborne particle testing, viable surface particle testing, gloved fingertip sampling and media-fill testing (also called aseptic manipulation testing).. Nonviable airborne particle sampling must be performed by ...

To provide useful information during military operations, or as part of other security situations, a biological aerosol detector has to respond within seconds or minutes to an attack by virulent biological agents, and with low false alarms. Within this time frame, measuring virulence of a known microorganism is extremely difficult, especially if the microorganism is of unknown antigenic or nucleic acid properties. Measuring live characteristics of an organism directly is not generally an option, yet only viable organisms are potentially infectious. Fluorescence based instruments have been designed to optically determine if aerosol particles have viability characteristics. Still, such commercially available biological aerosol detection equipment needs to be improved for their use in military and civil applications. Air has an endogenous population of microorganisms that may interfere with alarm software technologies. To design robust algorithms, a comprehensive knowledge of the airborne ...

We found that the atmosphere is a vector for the long-range transport -- typically 4,000Km -- of airborne microbes, including bacteria and fungi among others, says Carlos Duarte of KAUSTs Red Sea Research Center, who led the study. Even in the open ocean, more than half of the microbial load in the atmosphere is derived from land. Atmospheric transport may be important in redistributing pathogens across the globe, he adds.. The team found an average of 67,000 prokaryotes (non-nucleus-containing single-celled organisms like bacteria) per cubic meter of sampled air over the oceans compared to 190,000 bacteria per cubic meter of air over land. They also found an average of 32,000 eukaryotes (nucleus-containing microbes like fungi) per cubic meter of sampled air over the oceans compared to 240,000 fungal spores found per cubic meter of atmosphere over land.. The maximum values of eukaryotes were found over the North Atlantic and East Pacific, most likely affected by African and Asian dust-related ...

When my daughter was born more almost six years ago and started daycare, I noticed a seasonal pattern of illnesses (e.g. colds, norovirus in winter; hand, foot, and mouth disease in fall), which were eventually passed to my wife and me, causing numerous missed workdays.. Knowing that many childhood diseases are caused by viruses that can be transported either through the air or the oral-fecal route, I became obsessed with determining which viruses were actually floating in the air and if there was seasonality to the microbiome. Coincidentally, the Alfred P. Sloan Foundations Microbiology of the Built Environment had their first call for postdoctoral fellowships.. As a naïve young postdoc, I submitted a proposal to investigate the seasonal dynamics of the airborne bacterial and viral microbiome at my daughters daycare center, with the hypothesis that there was strong seasonality in microbial community composition. I also was very confident I would be able to complete the study within the ...

The emission and dispersal of bioaerosols from open-air commercial composting facilities continues to be contentious. A meta-dataset enumerating cultivable microorganism emission and downwind concentrations is not yet available. A dataset derived from repeated and replicated field studies over a period of two years at two commercial composting facilities is presented. The data characterises patterns in Aspergillus fumigatus, actinomycetes, Gram-negative bacteria and endotoxin emission and downwind concentrations. For all bioaerosols, compost agitation activities had a significant impact on concentrations; levels were variable up to 600. m downwind from site. Bioaerosols declined rapidly from source and exhibited a secondary peak 100-150. m from site boundary. All bioaerosols were found downwind from site in elevated concentrations. Compared to those found 100. m upwind, levels were significantly higher at 180. m downwind for A. fumigatus; at 300-400. m for actinomycetes and Gram negative ...
The Royal Society initiative to provide Rapid Assistance in Modelling the Pandemic (RAMP) has garnered a large number of scientists across the UK working voluntarily in a wide range of issues associated with the current pandemic. In this talk I will describe the outputs of the fifty odd scientists with expertise, broadly speaking, in fluid mechanics who have been considering aspects of the airborne transmission of the virus. Post lockdown major risks of infection are associated with occupancy of public buildings such as restaurants, schools, and other places where people congregate indoors, and in public transportation. I will describe what we have learnt over the past couple of months about the impact of building ventilation, the deposition of droplets, modes of exhalation and inhalation and other factors such as the effects of occupancy levels and the movement of people in these indoor environments, and what seem to be the key outstanding questions ...

Standard influenza is typically spread by people sneezing or coughing virus-laden particles into the air, which others breath in. Another way is by touching infected surfaces and then scratching your nose, eyes, face or ears. Viruses can live up to two days on surfaces which is why it is important to wash your hands and wipe down door handles, keyboards, machines, counters and other areas regularly. Another way to protect from airborne viruses is to use a spray bottle or diffuser with essential oils or natural formula. A simple spritz in the air will help neutralize those airborne critters while making your office, home or car smell great. Dont use lysol to spritz unless critical as this product as some studies have shown that continual inhalation of these chemicals has potential side effects ...

Watch the Video: Computer Viruses Go Airborne ]. Lee Rannals for redOrbit.com - Your Universe Online. University of Liverpool researchers have demonstrated how computer viruses could go airborne over WiFi networks.. The team has shown for the first time how WiFi networks could be used to make a computer virus contagious through the air, moving through densely populated areas as effectively as the common cold.. The researchers designed a virus known as Chameleon and simulated how it could move through these networks. They found that not only can Chameleon spread quickly between homes and businesses, but it was able to avoid detection and identify WiFi access points that are not protected by encryption and passwords.. The computer scientists performed a simulated attack on Belfast and London in a laboratory setting, finding that Chameleon behaved like an airborne virus by traveling through WiFi networks that connect households and businesses.. Densely populated areas have more access points in ...

After working diligently in the school system, Baker was offered an opportunity to help lower the mortality rate in Hell's Kitchen. It was considered the worst slum in New York at the turn of the century, with as many as 4,500 people dying every week. Baker decided to focus on the infant mortality rate in particular, as babies accounted for some 1,500 of the weekly deaths. Most of the infant deaths were caused by dysentery, though parental ignorance and poor hygiene were often indirectly to blame.[3] Baker and a group of nurses started to train mothers in how to care for their babies: how to clothe infants to keep them from getting too hot, how to feed them a good diet, how to keep them from suffocating in their sleep, and how to keep them clean.[1][12] She set up a milk station where clean milk was given out. Commercial milk at that time was often contaminated, or mixed with chalky water to improve colour and maximize profit. Baker also invented an infant formula made out of water, calcium ...

A close relative of a common little-understood human virus that causes an estimated 23 million episodes of intestinal illness, 50,000 hospitalizations and 300 deaths each year has been discovered in mice. The finding by scientists at Washington University School of Medicine in St. Louis is reported in the March 7 issue of the journal Science. Discovery of the new virus, known as murine norovirus 1 (MNV-1), may lead to a better understanding of its disease-causing cousins known as Norwalk viruses, or human noroviruses (HNVs). HNVs cause 90 percent of epidemic viral gastroenteritis worldwide, including those that sweep through cruise ships, nursing homes and military encampments causing debilitating diarrhea and vomiting ...
