Query: NC_014328:4387303 Clostridium ljungdahlii ATCC 49587 chromosome, complete genome
Lineage: Clostridium ljungdahlii; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: This strain was isolated from chicken yard waste and is studied for its ability to produce ethanol. This acetogenic species has the ability to convert carbon monoxide into ethanol. The yield of this process has been increased substantially in the laboratory by using a dual-fermentation system. A methanogenic conversion step has also been designed for utilizing some of the waste products generated during the synthetic process.

Lineage: Borrelia turicatae; Borrelia; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This strain was isolated in the USA from the soft tick Ornithodoros turicatae. Borrelia turicatae is the causative agent of tick-borne relapsing fever in the southwestern USA. Ticks become infected with Borrelia while feeding on an infected mammal, usually a rodent or squirrel. Borrelia then multiplies rapidly, causing a generalized infection throughout the tick. While feeding, the tick passes the spirochete into a mammalian host through its infectious saliva. Relapsing fever is characterized by period of chills, fever, headache, and malaise, followed by an asymptomatic, followed by another episode of symptoms. The cycle of relapsing is due to changes in the surface proteins of Borrelia, which allow it to avoid detection and removal by the host immune system. This antigenic variation is the result of homologous recombination of silent proteins into an expressed locus, causing partial or complete replacement of one serotype with another. These plasmids carry genes involved in antigenic variation and pathogenicity.
