Candida albicans is a species of yeast, a single-celled fungus that reproduces asexually, with daughter cells budding from parent cells. C. albicans is normally harmless and is commonly found on the skin and mucous membranes of the mouth, digestive and respiratory tracts and the vagina. Antibiotic treatment or compromised immune function may, however, lead to C. albicans infection. Common candida infections include oral and vaginal thrush.

$WHO says that it is estimated that ETEC causes about 220 million diarrhoea episodes globally, with about 75 million episodes in children under 5 years of age, resulting in between 18 700 and 42 000 deaths in children younger than 5 years. Several vaccines are in the pipeline.\nETEC is also a very common cause of traveler's diarrhea, this infection is usually self limiting, with no need for antibiotics. ETEC is common in developing countries.$

Neisseria meningitidis, often referred to as meningococcus, is a Gram-negative bacterium that can cause meningitis and other forms of meningococcal disease such as meningococcemia, a life-threatening sepsis. The bacterium is referred to as a coccus because it is round, and more specifically a diplococcus because of its tendency to form pairs.

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.
