2016年8月1日 · The detection of pathogenic bacteria dispersed in outdoor air is an important concern for public health, agriculture and biothreat surveillance. Promising real-time techniques include single particle laser desorption/ionisation time-of-flight mass spectrometry, which could for example specifically detect M. tuberculosis at relevant airborne ...

2020年12月18日 · Mycobacterium tuberculosis bacteria, the causative agent, have been shown to remain viable in air for up to 6 hours. The very small size of the bacterium (1-5µm range) allows it to remain suspended in air within bioaerosols when released from the lung, where it becomes subject to prevailing aerodynamics and can be transmitted to a susceptible ...

2022年3月28日 · Airborne microorganisms have various shapes (round, rod-shaped, or string-shaped) and can include many different species of bacteria, fungi, and algae. Consider all the different species of birds, their various sizes, shapes, and ways of living—then imagine that the same is true for airborne microorganisms.

This chapter discusses human viral, bacterial, and fungal diseases transmitted via aerosols. Viral diseases presented are influenza, severe acute respiratory syndrome (SARS), Norwalk-like viruses (NLVs) and hantavirus disease, measles, and varicella. Bacterial diseases are Legionnaires’ disease, tuberculosis, and nontubercule mycobacterial ...

2020年8月28日 · In this review, we describe detailed information on airborne microbes that commonly originate from soil and water through liquid–air and soil–air interface. The common bacteria and fungi in the atmosphere are the phyla of Firmicutes, Proteobacteria, Bacteroides, Actinobacteria, Cyanobacteria and Ascomycota, Basidiomycota, Chytridiomycota ...

2024年9月27日 · When a team of Spanish and Japanese researchers chartered a plane up to 10,000 feet into Japanese airspace, their aim was to analyze the chemistry of airborne dust particles. But what they found in...

2015年12月22日 · We have identified the following eight major categories of sources of airborne bacteria, viruses, and fungi in the built environment: humans; pets; plants; plumbing systems; heating, ventilation, and air-conditioning systems; mold; …

2016年8月1日 · Airborne bacteria affect both physical processes in the atmosphere, such as cloud formation and precipitation, and atmospheric chemistry via cloudborne bacteria. However, the hypothesis that a fraction of the atmospheric bacteria are forming actual microbial communities remains to be definitively proven.

Here, we summarize the current knowledge on airborne bacterial, viral, and fungal communities and discuss their potential consequences on human health. The current data suggest that bacterial pathogens are typically too sparse and short-lived in air to pose a significant risk for infecting healthy people.

2011年5月16日 · We used high-throughput pyrosequencing to analyze bacterial communities present in the aerosol fraction containing fine particulate matter of ≤2.5 μm from 96 near-surface atmospheric samples collected from cities throughout the midwestern United States and found that the communities are surprisingly diverse and strongly affected by the season.
