T. pyogenes contains a single round chromosome with anywhere from 2.3-2.4 base pairs depending on the strain. This chromosome is circular, characteristic of its class of actinobacteria. This bacteria is unique because it is characterized by a high conentration of guanine and cytosine bases. A high concentration of guanine and cytosine bases indicates a high melting point (Tm) which is characteristic of pathogenetic bacteria. These types of bacteria need a high Tm in order to survive in a host, so bacteria with a high concentration of adenine and thymine would most likely not thrive in a mammal as a host. T. pyogenes also has "relatively high number of pseudogenes" (NCBI). | T. pyogenes contains a single round chromosome with anywhere from 2.3-2.4 base pairs depending on the strain.

Trueperella
Description and Significance
Trueperella pyogenes is a gram positive bacteria which is "non-spore-forming, non-motile, non-capsulated, facultatively anaerobic rod" (NCBI). This bacteria thrives in areas rich with blood and/or serum, which is often used to culture. For this reason, T. pyogenes is responsible for many types of infections including mastitis, pneumonia, and abscesses often found in livestock and humans.
Genome Structure
T. pyogenes contains a single round chromosome with anywhere from 2.3-2.4 base pairs depending on the strain. This chromosome is circular, characteristic of its class of actinobacteria. This bacteria is unique because it is characterized by a high conentration of guanine and cytosine bases. A high concentration of guanine and cytosine bases indicates a high melting point (Tm) which is characteristic of pathogenetic bacteria. These types of bacteria need a high Tm in order to survive in a host, so bacteria with a high concentration of adenine and thymine would most likely not thrive in a mammal as a host. T. pyogenes also has "relatively high number of pseudogenes" (NCBI).
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
