Cryptococcus neoformans fungus, computer illustration. C. neoformans is a yeast-like fungus that reproduces by budding. An acidic mucopolysaccharide capsule completely encloses the fungus. It can cause the disease cryptococcosis, especially in immune deficient patients, such as those with HIV/AIDS (acquired immunodeficiency syndrome). It can infect the brain, causing meningitis or brain abscesses, lungs or skin. The most common clinical form is meningoencephalitis. It is caused by inhaling the fungus from soil that has been contaminated by pigeon droppings.

Streptococcus pyogenes bacteria. 3D computer illustration of Streptococcus pyogenes, or group-A Streptococcus, bacteria. S. pyogenes is a gram-positive spherical (coccus) bacteria. Many humans may carry it harmlessly in their throat or on the skin. Pathogenic strains can cause mild skin infections such as impetigo, uterine infection after childbirth, and blood poisoning (septicaemia). However, they can occasionally cause severe and even life-threatening disease - Streptococcus group A1 can be a deadly form of flesh eating bacteria.

Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms.
