Streptococcus dysgalactiae

Description and significance

Streptococcus dysgalactiae is a member of group C streptococci (GCS). This gram-positive bacteria is commonly found on the animal and can be isolated found from udders of cows with mild mastitis, an inflammation of the mammalian breast, and from blood and tissues of lambs with polyarthritis, an inflammation of five or more joints. [240 book, S.I.] Although it is extremely rare to be found on human, it can cause meningitis, an inflammation of the protective membrane covering the central nervous system. [2,3]

The virulence factors of group C streptococci were not studied as extensively as much as other streptococci group; as a result, researchers sequenced the whole genome of one strain, NS3396. [8] The study of the sequence revealed a number of similarities between Streptococcus pyogenes, a group A streptococci (GAS), and Streptococcus dysgalactiae. This allows researchers to understand the pathology of Streptococcus dysgalactiae.[8]

Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?

Cell structure and metabolism

Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?

Current Research
