Query: NC_005823:1105524 Leptospira interrogans serovar Copenhageni str. Fiocruz L1-130
Lineage: Leptospira interrogans; Leptospira; Leptospiraceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This strain was isolated from a patient with severe leptospirosis during an epidemic in 1996. This organism is the causative agent of leptospirosis, a tropical zoonosis transmitted by direct contact with the urine of infected animals. This motile and obligately aerobic organism grows optimally at 28-30 C. Many serovars are adapted for specific mammalian reservoir hosts, which harbor the organisms in their renal tubules and shed them in their urine. Because of the large spectrum of animal species that serve as reservoirs, leptospirosis is considered to be the world's most widespread zoonotic disease.
Subject: NC_011959:972798 Thermomicrobium roseum DSM 5159, complete genome
Lineage: Thermomicrobium roseum; Thermomicrobium; Thermomicrobiaceae; Thermomicrobiales; Chloroflexi; Bacteria
General Information: Thermomicrobium roseum DSM 5159 was isolated from Yellowstone National Park, USA. Obligate thermophile with unusual cell wall structure. Thermomicrobium roseum is a red-pigmented, rod-shaped, Gram-negative extreme thermophile that possesses both an atypical cell wall composition and an unusual cell membrane that is composed entirely of long-chain 1,2-diols. Analyses of environmental sequences from hot spring environments show that T.roseum displays a low quantity but ubiquitous presence in top layers of microbial mats. Few standard housekeeping genes are found on the megaplasmid, however, it does encode a complete system for chemotaxis including both chemosensory components and an entire flagellar apparatus. T. roseum oxidizes CO aerobically, making it the first thermophile known to do so. In addition, is is propose that glycosylation of its carotenoids plays a crucial role in the adaptation of the cell membrane to this bacterium's thermophilic lifestyle. Because T. roseum is a deep-branching member of this phylum, eventhough this species is not photosynthetic, analysis of the genome provides some insight into the origins of photosynthesis in the Chloroflexi.
