Influenza A virus subtype H1N1 particles. Digitally-colorized transmission electron micrograph. The surface proteins located on the surface of the virus particles are shown in black. This virus, first detected in 2009, belongs to the Orthomyxoviridae family and contains the glycoproteins haemagglutinin and neuraminidase, hence the H and the N in the subtype name. Some H1N1 strains cause infection in humans and others in pigs (Pig Flu, Swine Flu, Swine Influenza). Pig flu (Swine Influenza, Swine Flu) is a respiratory illness that occurs in pigs. Transmission of H1N1 from pigs to humans (Zoonosis) is not common and does not always lead to human illness. The virus can be infectious from human to human. Symptoms of this virus in people are similar to the regular flu which include fever, cough, sore throat, body aches, headache, chills and fatigue.

Common indoor / allergenic mold (Aureobasidium pullulans); fungal hyphae producing spores (often growing yeast-like). Synonym - Pullularia. Aureobasidium is a common indoor mold / mildew that grows in damp places. It occurs indoors in very damp areas and in free standing water, such as condensate pans, or following a flood. Spores only become airborne through mechanical disruption of contaminated materials or aspiration of contaminated water. It is not a primary human pathogen nor is it recognized as a producer of significant mycotoxins. High airborne levels of this fungus have been associated with allergic complaints probably due to respiratory irritation mediated by cell-wall components (e.g. beta glucans, glycoproteins), it has also been known as an irritant, and to cause pulmonary problems.

This virus causes monkeypox which is similar to smallpox, but with a lower death rate. The virus belongs to the Orthopoxvirus genus in the family Poxviridae. It can be transmitted to people from a variety of wild animals and can spread through human-to-human transmission.
