Query: NC_017168:2626996 Yersinia pestis A1122 chromosome, complete genome

Lineage: Yersinia pestis; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: Specific virulence factors are encoded within pathogenicity islands (PAIs) that are required for the invasive phenotype associated with Yersinia infections. One key virulence plasmid contained by the three human-specific pathogens is pCD1/pYv, which encodes a type III secretion system for the delivery of virulence proteins that contribute to internalization into the host cell. It is the causative agent of plague (bubonic and pulmonary) a devastating disease which has killed millions worldwide. The organism can be transmitted from rats to humans through the bite of an infected flea or from human-to-human through the air during widespread infection. Yersinia pestis is an extremely pathogenic organism that requires very few numbers in order to cause disease, and is often lethal if left untreated. The organism is enteroinvasive, and can survive and propagate in macrophages prior to spreading systemically throughout the host. Yersinia pestis also contains a PAI on the chromosome that is similar to the SPI-2 PAI from Salmonella that allows intracellular survival in the organism.

Subject: NC_009053:1942973 Actinobacillus pleuropneumoniae L20, complete genome

Lineage: Actinobacillus pleuropneumoniae; Actinobacillus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria

General Information: This organism is an obligate parasite of pigs. The bacterium colonizes and invades the porcine lower respiratory tract and can survive phagocytosis by macrophages, eventually resulting in the death of the macrophage cell. Three RTS toxins, which result in cell damage, are produced by this organism.
