Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
"Finegoldia magna" is a slow-growing, non-spore-forming, Gram-positive anaerobic coccus (GPAC) bacteria.
- The Genus namesake is the American microbiologist Sydney Martin Finegold.
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?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Cell Structure
- Finegoldia magna is a Gram-positive anaerobic coccus (GPAC) bacteria, in which "coccus" indicates a spherical cell shape. Gram-positive indicates a bacterium with thick petidoglycan cell walls.
- It has a cell size that varies from 0.8 µm and 1.6 µm in diameter, and cells occur predominantly in clusters but occasionally in short chains or pairs, as in Figure 2.
- This bacteria has sortase-dependent pilli, which are hair-like structures characteristic of bacterial adhesion and colonization (i.e., important for biofilm formation) as well as host infection. [5]
Survival & Energy
- As an anaerobe, F. magna requires an oxygen-free environment to grow. However, in a 1998 experiment by Murdoch et al., F. magna isolates were plated on agar and exposed to air. After 48 hours, some clusters survived, indicating a level of oxygen tolerance. [6]
Metabolism & Products
- F. magna 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.
