Query: NC_009513:618000 Lactobacillus reuteri F275, complete genome
Lineage: Lactobacillus reuteri; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain (JCM 1112, F275) is the type strain for the species. It is a human isolate, which is unable to colonize the intestinal tract of mice. Normal gut bacterium. They are commonly found in the oral, vaginal, and intestinal tracts of many animals. They are important industrial microbes that contribute to the production of cheese, yogurt, and other products such as fermented milks, all stemming from the production of lactic acid, which inhibits the growth of other organisms as well as lowering the pH of the food product. Industrial production requires the use of starter cultures, which are carefully cultivated, created, and maintained. These cultures produce specific end products during fermentation that impart flavor to the final product, as well as contributing important metabolic reactions, such as the breakdown of milk proteins during cheese production. The end product of fermentation, lactic acid, is also used as a starter molecule for complex organic molecule syntheses. Lactobacillus reuteri is a member of the normal microbial community of the gut in humans and animals. This organism produces antibiotic compounds, such as reutericin and reuterin, which have inhibitory effects on pathogenic microorganisms.
Subject: NC_006570:24636 Francisella tularensis subsp. tularensis Schu 4, complete genome
Lineage: Francisella tularensis; Francisella; Francisellaceae; Thiotrichales; Proteobacteria; Bacteria
General Information: This subspecies is virulent in humans, and the strain is a clinical isolate that is also virulent in an animal model. Originally isolated from a human case of tularemia in 1951. There are a large number of insertion sequences including a mariner element, which is a transposon typically found in eukaryotes and is the first instance of this element to be found in a microbe, which may have acquired it during transit through one of the insect vectors. Causative agent of tularemia. This organism was first identified by Edward Francis as the causative agent of a plague-like illness that affected squirrels in Tulare county in California in the early part of the 20th century. The organism now bears his name. The disease, which has been noted throughout recorded history, can be transmitted to humans by infected ticks or deerflies, infected meat, or by aerosol, and thus is a potential bioterrorism agent. This organism has a high infectivity rate, and can invade phagocytic and nonphagocytic cells, multiplying rapidly. Once within a macrophage, the organism can escape the phagosome and live in the cytosol. It is an aquatic organism, and can be found living inside protozoans, similar to what is observed with Legionella.
