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. The infection may cause meningitis, and may also be located in the lungs, skin or other body regions. The most common clinical form is meningoencephalitis. It is caused by inhaling the fungus found in soil that has been contaminated by pigeon droppings.

Escherichia coli (Ecoli 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.
