Query: NC_014100:172452 Caulobacter segnis ATCC 21756 chromosome, complete genome
Lineage: Caulobacter segnis; Caulobacter; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Isolation: Soil; Temp: Mesophile; Habitat: Fresh water. Caulobacter segnis strain ATCC 21756 is a prostheca-less bacterium belonging to the genus Caulobacter; it was isolated from soil although its habitat is considered to be fresh-water. The absence of a stalk in this genus makes this an interesting bacterium to study.
Subject: NC_011025:183287 Mycoplasma arthritidis 158L3-1, complete genome
Lineage: Mycoplasma arthritidis; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: This organism causes arthritis in both rats and mice. Strains of Mycoplasma arthritidis can be virulent or avirulent depending, in part, on the presence of the MAV1 bacteriophage. This genus currently comprizes more than 120 obligate parasitic species found in the wide spectrum of hosts, including humans, animals, insects and plants. The primary habitats of human and animal mycoplasmas are mucouse membranes of the respiratory and urogenital tracts, eyes, mammary glands and the joints. Infection that proceeds through attachment of the bacteria to the host cell via specialized surface proteins, adhesins, and subsequent invation, results in prolonged intracellular persistence that may cause lethality. Once detected in association with their eukaryotic host tissue, most of mycoplasmas can be cultivated in the absence of a host if their extremely fastidious growth requirements are met.
