Query: NC_009505:264963 Brucella ovis ATCC 25840 chromosome I, complete sequence

Lineage: Brucella ovis; Brucella; Brucellaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This strain was isolated from sheep tissue in Australia. Causes brucellosis in sheep. This organism specifically affects sheep, causing ovine brucellosis which results in significant economic losses. Infection by the organism can cause infertility in rams as the bacterium preferentially colonizes the genital tract, and causes inflammation of the epididymis which leads to necrotic lesions and a decrease in sperm numbers and motility. This bacterium, like other Brucella, is an intracellular pathogen that infects phagocytic cells such as macrophages. Bacterial cells produces a lipopolysaccharide that lacks O-antigen side chains, which results in a rough colony phenotype, and aids in differentiation as compared to other Brucella.

Subject: NC_008593:2457594 Clostridium novyi NT, complete genome

Lineage: Clostridium novyi; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria

General Information: This strain (NT) was created so that it lacks the lethal toxin. Injection of spores of this organism into mice harboring tumors resulted in an increased immune response and destruction of the tumor tissue in a method known as COBALT (combination bacteriolytic therapy) when the spores along with chemotherapeutic agents or radiation are co-administered. The anaerobic bacteria preferentially target hypoxic cancer tissue and stimulate immune responses to that tissue. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. Clostridium novyi is an anaerobic bacterium found in soil, aquatic sediments, and intestinal tract of both animals and humans. Some types produce lethal toxins.
