Query: NC_014121:1357339 Enterobacter cloacae subsp. cloacae ATCC 13047 chromosome, complete
Lineage: Enterobacter cloacae; Enterobacter; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Enterobacter species are found in natural environments such as water, sewage, soil, and vegetables; some species are found in human and animal species. Enterobacter cloacae is a prevalent nosocomial pathogen as it is highly resistant to disinfectants and antimicrobial agents. E.cloacae subsp. cloacae strain ATCC 13047 was isolated from human cerebrospinal fluid in 1890 and is the type strain. These "ICU bugs" cause significant morbidity and mortality, and infection management is complicated by multiple antibiotic resistance. These bacteria possess inducible beta-lactamases, which are undetectable in vitro but are also responsible for resistance during treatment.
Subject: NC_006511:2718401 Salmonella enterica subsp. enterica serovar Paratyphi A str. ATCC
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This serovar has a narrow host range and causes a typhoid-like (paratyphoid fever) illness in humans. It is especially prevalent in southern and eastern Asia, and has been associated with some particularly virulent outbreaks. A number of isolates are increasingly antibiotic resistant. 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.
