Overview


  • Streptococcus parauberis is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, coccus bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 34.8-36.5%. Streptococcus parauberis is probably a rare gut coloniser. (Williams1990; Whiley2011Bergey)



  • This organism has been recovered from human faeces, raw milk, and cows. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: animal pathogen). Is a known human pathogen. A possible gut commensal. Robust growth can have negative consequences for gut health.

  • Streptococci are members of the normal flora. Virulence factors of group A streptococci include (1) M protein and lipoteichoic acid for attachment; (2) a hyaluronic acid capsule that inhibits phagocytosis; (3) other extracellular products, such as pyrogenic (erythrogenic) toxin, which causes the rash of scarlet fever; and (4) streptokinase, streptodornase (DNase B), and streptolysins. Some strains are nephritogenic. Immune-mediated sequelae do not reflect dissemination of bacteria. Nongroup A strains have no defined virulence factors. In humans, diseases associated with the streptococci occur chiefly in the respiratory tract, bloodstream, or as skin infections. [https://www.ncbi.nlm.nih.gov/books/NBK7611/]

    The genus Streptococcus , a heterogeneous group of Gram-positive bacteria, has broad significance in medicine and industry. Various streptococci are important ecologically as part of the normal microbial flora of animals and humans; some can also cause diseases that range from subacute to acute or even chronic. Among the significant human diseases attributable to streptococci are scarlet fever, rheumatic heart disease, glomerulonephritis, and pneumococcal pneumonia. Streptococci are essential in industrial and dairy processes and as indicators of pollution. [https://www.ncbi.nlm.nih.gov/books/NBK7611/]
