Largest of the lactic acid bacteria group. Included 50+ sub-species. The name means 'acid-loving milk-bacterium' and metabolizes sugars into lactic-acid. This bacteria is found in the gastrointestinal tract, mouth, and vagina of humans and other animals. It is found to control the overgrowth of the fungus Candida albicans.

This bacteria also plays a role in the production of food products such as cheeses, yoghurts and some other fermented foods. They actually break down the proteins in cheeses and contribute to the final taste of the product.

This is also widely available as an oral supplement to aid digestion and support "immune health." You now find this in many foods boasting of immune system and gastrointestinal support such as baby formula, drinks, yoghurts, health foods and more. It is also recommended for patients after finishing a course of antibiotics in order repopulate healthy intestinal flora.

This bacteria is generally found in soil and effects insects such as: moths, mosquitoes, blackfiles, aphids, and wasps. The bacteria generally does not effect humans and has been used as a replacement for spray pesticides which contain poisonous chemicals, that damage plant, insect and human alike.

This species has also been used in genetically engineered plants. The bacteria are genetically spliced into the cells of the plant to be modified, the resulting plant actually produces the B. thuringiensis bacteria on a cellular level and is itself categorized as a pesticide. This practice is highly controversial and studies continue today on the dangers posed by the addition of the bacteria to hundreds of plant species consumed by humans for food and used as animal feed.

Methicillin-Resistannt Staphylococcus aureus (MRSA)

Pseudomonas aeruginosa is a common bacterium that can cause disease in animals, including humans. It is citrate, catalase, and oxidase positive. It is found in soil, water, skin flora, and most man-made environments throughout the world. It thrives not only in normal atmospheres, but also in hypoxic atmospheres, and has, thus, colonized many natural and artificial environments. It uses a wide range of organic material for food; in animals, its versatility enables the organism to infect damaged tissues or those with reduced immunity.
