Over the past 25 years, Lyme disease has evolved from a mysterious focus of childhood illness in rural Connecticut to the most common tick-borne illness in the United States. Other tick-borne infections may be found in the Northeastern US, although less commonly than Lyme disease, including Babesia microti, Ehrlichiosis, Tularemia, and Rocky Mountain Spotted Fever.There are more than a million species of fungi, but only about 400 cause diseases in humans, animals or plants. Fungi are multicellular (eukaryotic) microorganisms whose genetic material is contained within a cell nucleus. Fungi require preformed organic compounds for energy and do not contain chlorophyll.

There are two broad groups of fungi: yeasts and molds. While these definitions are not mutually exclusive, mold spores germinate to produce the branching filaments known as hyphae. Yeasts are solitary rounded forms that reproduce by making more rounded forms through mechanisms such as budding or fission.
