Query: NC_015690:8019859 Paenibacillus mucilaginosus KNP414 chromosome, complete genome
Lineage: Paenibacillus mucilaginosus; Paenibacillus; Paenibacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Paenibacillus mucilaginosus is critical silicate bacteria in the biogeochemical cycling of potassium, phosphorus, and other soil elements, and is widely used in agriculture, bioleaching, and wastewater treatment. P. mucilaginosus is able to degrade insoluble soil minerals with the release of nutritional ions and fix nitrogen, and thus it has been successfully used as a biofertilizer since the 1990s. The exocellular polysaccharides produced by P. mucilaginosus is also an effective bioflocculant, and thus plays a potential role in the treatment of wastewater and biohydrometallurgy.
Subject: NC_004631:283289 Salmonella enterica subsp. enterica serovar Typhi Ty2, complete
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This pathogenic strain of Salmonella typhi was isolated in the early 1970s. It contains no multidrug resistance plasmids and has been used for vaccine development. This serovar is a human-specific organism that causes the life-threatening illness Typhoid fever which is acquired by coming into contact with contaminated food or water. Annually, 17 million people are infected, with 600,000 fatalities, mostly in developing countries. It contains multiple fimbrial operons that may be used to create extracellular appendages for attachment and entry into host intestinal epithelial cells. Causes enteric infections. This group of Enterobactericiae have pathogenic characteristics and are one of the most common causes of enteric infections (food poisoning) worldwide. They were named after the scientist Dr. Daniel Salmon who isolated the first organism, Salmonella choleraesuis, from the intestine of a pig. The presence of several pathogenicity islands (PAIs) that encode various virulence factors allows Salmonella spp. to colonize and infect host organisms. There are two important PAIs, Salmonella pathogenicity island 1 and 2 (SPI-1 and SPI-2) that encode two different type III secretion systems for the delivery of effector molecules into the host cell that result in internalization of the bacteria which then leads to systemic spread.
