Query: NC_010544:850502 Candidatus Phytoplasma australiense, complete genome
Lineage: Phytoplasma australiense; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria
General Information: Phytoplasmas inhabit phloem (food-conducting vascular tissue) sieve elements of plants where they cause a variety of diseases. Transmission between plants is via insects that feed on the phloem. Candidatus Phytoplasma australiense was identified in diseased Chardonnay grapevines from South Australia. Symptoms include a yellowing of the leaves and reduced leaf size, which leads to reduced plant size and lower yields.
Subject: NC_014760:299392 Mycoplasma bovis PG45 chromosome, complete genome
Lineage: Mycoplasma bovis; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: This bacterium causes a contagious disease of cattle causing respiratory disease, mastitis, and arthritis. It is found worldwide and is inherently resistant to certain groups of antibiotics because it does not possess a cell wall. More recently, this species has become resistant to tetracycline, tilmicosin and spectinomycin which have been traditionally used in its control. The disease is spread between herds by the transfer of infected but seemingly healthy animals which shed viruses. It has also been introduced into healthy herds via frozen semen collected from an infected bull. The economic losses and negative impact on international trade from this disease have been considerable, and efforts are now underway to develop a vaccine.
