Query: NC_000963:110500 Rickettsia prowazekii str. Madrid E, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain is an egg-passaged attentuated avirulent strain that has been used as a live vaccine and was originally isolated from a typhus patient in Madrid. This species is the causal agent of typhus. The bacteria are transmitted via an insect, usually a tick, to a host organism, in this case humans, where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Transovarial transmission (from mother to offspring) occurs in the invertebrate host.
Subject: NC_008505:36638 Lactococcus lactis subsp. cremoris SK11 plasmid 3, complete
Lineage: Lactococcus lactis; Lactococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain is recognized for the beneficial flavors it produces during cheese production. This subspecies is used to make hard cheeses. Microorganism used in cheese production. This microbe is a member of the lactic acid bacteria and produces lactic acid from sugars. It is found in many environments including plant and animal habitats. Lactococcus lactis is used as a starter culture for the production of cheese products (such as cheddar) and in milk fermentations and, as such, is one of the most important microbes in the food industry. The degradation of casein, acidification by lactic acid, and production of flavor compounds, processes that are caused by the bacteria, contribute to the final product.
