“…Interestingly, colon cancer has also been reported in the presence of S. bovis infection from other sources, including: septic arthritis [40], infection postknee replacement [41], neck abscess [42], thoracic empyema [43] and even a surgical wound posttransvesical prostate resection for an adenoma [44]. In addition, although at a much lower prevalence, there have also been reports linking colon cancer with other streptococcus species, including: endocarditis from Streptococcus suis [45], Streptococcus faecalis [11], Streptococcus pneumonia [46] and Streptococcus equines [17], or bacteraemia with Streptococcus sanguis [47] and Streptococcus salivaris [19].…”

Streptococcus bovis endocarditis, a silent sign for colonic tumour

2010

Streptococcus bovis endocarditis and/or bacteraemia is an early clue to the likely presence of colorectal cancer. Whilst further studies are required to determine the precise pathophysiology, clinicians should be aware of this association. It is advisable to investigate rigorously for colon cancer in all patients presenting with S. bovis endocarditis/bacteraemia; such patients may also present with liver disease or, occasionally, extra-colonic malignancy.

“…4 The associations of this species with colon cancer development, bacteremia and endocarditis have been divergent and remain unclear primarily because the studies were performed before the reclassification of S. bovis and therefore different S. bovis biotypes were used. [5][6][7][8][9][10] Recently, the potential association of correctly identified strains was evaluated, [11][12][13][14][15] Streptococcus gallolyticus subspecies gallolyticus (S. bovis biotype I) was associated to colon cancer in Asia and the United States, 11 Streptococcus infantiarus coli (S. bovis II/1) in Europe and S. gallolyticus subspecies pasterianus (S. bovis biotype II/2) in Asia. 12,13 Results suggest that S. gallolyticus (S. bovis biotype I) may be more likely than biotype II to be associated with both endocarditis and colonic lesions.…”

Our aim was to examine the humoral immune response against Streptococcus gallolyticus subspecies gallolyticus antigens in individuals subjected to a routine colonoscopy in which colon adenomatous polyps were present or not. Serum samples from 133 individuals with adenomatous polyps and serum samples from 53 individuals with a normal colonoscopy were included. Western blot was performed in all subjects using a whole cell antigen from S. gallolyticus ATCC 9809, and rabbit antisera against the whole cell bacteria was prepared as a control. By analyzing the immune profile of the rabbit‐immunized sera by Western‐blot, at least 22 proteins were identified as immunogenic in S. gallolyticus. When we evaluated sera from human subjects, two proteins of approximately 30 and 22 kDa were most prominent. Based on this 2‐protein band pattern, Western‐blot profiles from human subjects were compared. The detection of a protein band of 22 kDa was associated with the presence of adenomatous polyps in colon [odds ratios (OR) 7.98, 95% confidence intervals (CI): 3.54–17.93], p < 0.001. When the presence of the 30 kDa protein alone or both the 22 and 30 kDa proteins were analyzed, the OR increased to 22.37 (95% CI: 3.77–131.64), p < 0.001. The specificity was 84.9 for the presence of the 22 kDa protein, and 98.1 for the presence of the 30 kDa protein alone or both 22 and 30 kDa bands. Serum from individuals with adenomatous polyps recognized two proteins from S. gallolyticus. This result confirmed the possible association of S. gallolyticus with adenomatous polyps in the colon.

“…pasteurianus (formerly S. bovis biotype II) bacteraemia, 48% are of biliary origin; however, bacteraemia caused by S. gallolyticus subsp. gallolyticus is very rarely of biliary origin [5,12,21,24,27]. The different association of SBG species with biliary tract infections could explain the differences found in several studies of SBG bacteraemia, in which the bacteraemia of biliary origin ranges between 0 and 38% depending on the percentage of cases involving S. gallolyticus subsp.…”

“…The SBG has also been linked to osteoarticular infections, urinary tract infections, meningitis, peritonitis and spontaneous bacteraemia in cirrhotic, neonatal infections and non-colorectal cancer [6][7][8][9][10][11]. Over 20 years ago, Ruoff et al [12] reported the association between S. bovis biotype II and biliary tract infections. Since then, this association has received little attention [13][14][15][16]; the percentage of SBG bacteraemia with biliary origin has been estimated in several reports at between 0 and 38% [17][18][19][20][21][22][23][24][25][26][27].…”

Streptococcus bovis is a well-known cause of endocarditis, but its role in other infections has not been well described. We analysed prospectively all patients with biliary tract infections caused by S. bovis group during the period 1988-2011. We selected those cases associated with cholangitis and cholecystitis, defined according to Tokyo guidelines. Identification of the strains was performed using the API 20 Strep and the GP card of the Vitek 2 system, and was confirmed by molecular methods. Our series included 51 cases (30 cholangitis and 21 cholecystitis). The associated microorganisms were: Streptococcus infantarius (biotype II/1) 29 cases (57%), Streptococcus gallolyticus subsp. pasteurianus (biotype II/2) 20 cases (39%) and Streptococcus gallolyticus subsp. gallolyticus (biotype I) two cases (4%). The only difference found between S. infantarius and S. gallolyticus subsp. pasteurianus was a greater association of the first with malignant strictures of the bile ducts: 48% (14/29) versus 5% (1/20), p <0.001. Thirty-seven of the cases also had bacteraemia, causing 20% (37/185) of all S. bovis bacteraemia, with differences between S. gallolyticus subsp. gallolyticus (2/112; 2%) and the other two microorganisms: S. infantarius and S. gallolyticus subsp. pasteurianus (35/73; 48%; p <0.001). The vast majority of biliary tract infections due to S. bovis group are caused by S. infantarius and S. gallolyticus subsp. pasteurianus (S. bovis biotype II), and nearly half of the bacteraemia due to these two species has a biliary source (43% of the S. infantarius and 56% of S. gallolyticus subsp. pasteurianus).
