2015). Bioaerosols are airborne biological particles consisting of cells, pollen, fungi, parasite eggs, bacteria or viruses (Blais-Lecours et al. 2015; Breza-Boruta 2016; Douglas et al. 2017). Air in a sow breeding barn was investigated to determine the biomass composition of bioaerosols using molecular methods supplemented with microscopic and cultivation-dependent approaches.

bioaerosols as are filters [Macher and Hansson 1987]. Impactors used for the collection of airborne microorganisms may have range from a single slit to more than 400 holes per stage. The particles impact onto growth medium with one or more bacterial or fungal colonies forming at some impaction sites.

Numerous air contamination sources can be found there, and zoos are both working environments and popular tourist objects. The aim of this study was to assess bacterial aerosol levels in premises for animals (giraffes, monkeys, pheasants and ostriches) of the Kraków Zoo Airborne fungi, termed fungal bioaerosols, have received attention due to the association with public health problems and the effects on living organisms in nature. There are growing concerns that fungal bioaerosols are relevant to the occurrence of allergies, opportunistic diseases in hospitals, and outbreaks of plant diseases. The search for ways of preventing and curing the harmful effects 2017-11-13 · An introduction to the microbiology of bioaerosols and their impact on the world in which we live. The microbiology of aerosols is an emerging field of research that lies at the interface of a variety of scientific and health-related disciplines.

Bioaerosols in the atmosphere over the Amazon rain forest were analyzed by molecular biological staining and microscopy. Eukaryotic, bacterial and archaeal aerosols were quantified in time series and altitude profiles exhibiting clear differences in number concentrations and vertical distributions. Se hela listan på frontiersin.org The need for accurate measurement of bioaerosols has received increased attention in recent years owing to concerns with mold contamination in indoor environments and the threat of bioterrorism. Sample analysis methods include culture, microscopic, biochemical, immunological, or molecular biological assays. Mailbags and letters may both contribute to the formation of bioaerosols. Manual mail unpacking and sorting resulted in a significant increase of airborne culturable microorganisms.

Ekaterina Mirskaya, Igor E. Agranovski, Sources and mechanisms of bioaerosol generation in occupational environments, Critical Reviews in Microbiology, 10.1080/1040841X.2018.1508125, (1-20), (2018). Crossref The control of microbial aerosols is the major driver in the design of microbiological containment laboratories. The provision of a negative-pressure laboratory area with a high efficiency particulate air (HEPA) filtered exhausted ventilation system is intended to prevent the escape of infectious aerosols from the facility. Important mechanisms that remove bioaerosols from indoor air include air exchange, deposition onto indoor surfaces, and active filtration. The review summarizes knowledge about size-dependent particle deposition in different regions of the respiratory tract, techniques for measuring indoor bioaerosols, and evidence for diseases caused by airborne exposure to bioaerosols.
