S. bovis

Habitat Information

This sample was cultivated from the edge of a fence wall in a subdivision in Austin, TX near a garden bed. The surrounding soil was moist from a sprinkler having been left on and rocky. This area was also frequented by dogs and household pets.

Description and Significance

Streptococcus bovis is a gram-positive bacterium that grows in pairs or chains of cocci and is a normal inhabitant of the gastrointestinal tract. It is both oxidase and catalase-negative and is a non-motile, non-sporulating, facultative anaerobe. S. bovis is classified as a group D streptococci, gamma-hemolytic species causing no hemolysis, accompanied only by the strain streptococcus equinus. S. bovis is associated closely with infective endocarditis and has links to colon cancer, liver diseases, neonatal septicemia, and more rarely, neonatal meningitis and adult meningitis.

Streptococcus bovis has antimicrobial susceptibility to penicillin, Ticarcillin, sulfisoxazone, Azlocillin and ceftazidime.

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? Include S Ribosomal sequence that you obtained from PCR and sequencing here.


Cell Structure, Metabolism and Life Cycle

streptococcus bovid's cell surface has a variety of proteins and polysaccharides that are either covalently or non- covalently bonded to the cell wall, much like other gram-positive bacteria. The cell surface can be divided into four further categories: (1) LPXTG- like proteins, (2) pseudopili, (3) surface lipoproteins, and (4) capsule. The capsule is required in order for the organism to be resistant to phagocytosis. Interesting features of cell structure; how it gains energy; what important molecules it produces.

Physiology and Pathogenesis

Biochemical characteristics, enzymes made, other characteristics that may be used to identify the organism; contributions to environment (if any).
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
