Query: NC_010943:1379707 Stenotrophomonas maltophilia K279a, complete genome
Lineage: Stenotrophomonas maltophilia; Stenotrophomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: Stenotrophomonas maltophilia K279a was isolated from blood infection. This species is an uncommon but serious source of infection in patients with breathing tubes such as endotracheal or tracheostomy tubes, or with chronically indwelling urinary catheters. Although the organism can colonize the devices without causing an infection, under certain conditions it can cause pneumonia, urinary tract infections, or an infection of the blood. This organism can also cause infection in immunocompromised patients. It has resistance to many commonly used antibiotics and therefore is often difficult to eradicate. Most strains are resistant to co-trimoxazole.
Subject: NC_004631:2584244 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.
