''Bacillus licheniformis'' is a bacterium that is commonly found in soil and bird feathers. Birds that tend to stay on the ground more than the air (i.e. sparrows) and on the water (i.e. ducks) are common carriers of this bacterium; it is mostly found around the bird's chest area and back plumage.

Description and significance

Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.


Ureaplasma parvum is a new species of Ureaplasma urealyticum. In the past Ureaplasma urealyticum was separated into U. urealyticum biovar (1) and biovar (2). Until recently, new research has suggested replaced the separation with the creation of 2 new species known has Ureaplasma parvum and U. urealyticum. Ureaplasma parvum was the formerly known U. urealyticum biovar (1). It is a pathogenic ureolytic mollicute (mycoplasma) commonly found in healthy and diseased humans. It is one of the smallest free living organisms known. Linked to many neonatal, male, and female specific diseases; its genome was sequenced in 2000. Favoring acidic growth medium’s it colonizes the genital and lower urinary tracts of humans.

Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?

Ureaplasma parvum is a mycoplasma that has a genome consisting of 750,000 base pairs. It’s genome sequence was completed in 2000. Known macrolide resistant mutants have been associated with mutations in the 23S rRNA and in the L4 and L22 ribosomal proteins.

Cell structure and metabolism

Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?

Current Research

Enter summaries of the most recent research here--at least three required
