Toxoplasma gondii, illustration. T. gondii is a species of parasitic protozoa that can be carried by all known mammals. It causes toxoplasmosis, a usually minor and self-limiting disease. It can, however, have serious or even fatal effects on an unborn foetus if the mother contracts toxoplasmosis during pregnancy.

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.
