Query: NC_004842:62000 Anaplasma marginale str. St. Maries, complete genome
Lineage: Anaplasma marginale; Anaplasma; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain was recovered from an acutely infected cow from Northern Idaho, USA and bears an msp1a genotype of JBB. This strain is transmitted by ticks and is known to be virulent. This organism is the causative agent of bovine anaplasmosis and is an obligate intracellular pathogen. Transmission occurs via an arthropod vector (tick) and is a major problem in tropical regions where it causes severe morbidity in cattle populations. The bacterium lives intracellularly within membrane-bound vesicles in the host erythrocyte, a cell type which it specifically targets, resulting in severe anemia for the host organism.
Subject: NC_001263:243000 Deinococcus radiodurans R1 chromosome 1, complete sequence
Lineage: Deinococcus radiodurans; Deinococcus; Deinococcaceae; Deinococcales; Deinococcus-Thermus; Bacteria
General Information: This red-pigmented organism's name means "strange berry that withstands radiation", marking the fact that this organism is one of the most radiation-resistant known. It can tolerate radiation levels at 1000 times the levels that would kill a human and it was originally isolated in 1956 from a can of meat that had been irradiated with X-rays. The resistance to radiation may reflect its resistance to dessication, which also causes DNA damage. This organism may be of use in cleaning up toxic metals found at nuclear weapons production sites due to the radiation resistance. This bacterium is also a highly efficient transformer, and can readily take up exogenous DNA from the environment, which may also aid DNA repair. This organism carries multiple copies of many DNA repair genes, suggesting a robust system for dealing with DNA damage. The recombination system may rely on multiple copies of various repeat elements found throughout the genome.
