Trichosporon cutaneum. A yeast fungus with septate hyphae and pseudohyphae. Magnification 500, scanning electron microscopy. Trichosporon spp. is a yeast isolated from soil, water, vegetables, mammals, and birds. It is also a part of the normal flora of mouth, skin and nails and is the causative agent of white piedra, superficial infections and invasive trichosporonosis in humans. Trichosporon cutaneum has been often synonymous and classified as Trichosporon beigelii. Courtesy of Dennis Kunkel.

At any moment, an estimated 10^30 bacterial and archaeal genes are mediating essential ecological processes throughout the world. The new field of metatranscriptomics, using an approach that sequences microbial genes expressed within intact natural communities, allows us to understand microbial gene expression patterns. It is now feasible to deeply sequence the assortment of microbial community transcripts from a particular time and place, whether from bacteria, archaea, or small eukaryotes in the ocean, the soil, or the human gut.

This bacteria is a microaerophilic, gram-negative, non-spore forming, non-fermenting, helical-shaped, motile pathogen. It is commonly found in animal excrement and causes the infectious disease Campylobacteriosis. This organism is one of the most common causes of human illness in the world. Most cases come from handling or ingesting raw or under-cooked poultry meat. Symptoms appear within 2 to 5 days after exposure and may include diarrhea (sometimes bloody), cramping, abdominal pain, fever, nausea and vomiting.
