“…equinus complex isolates, partial 16S ribosomal RNA (rRNA) sequencing was performed as previously described. 19,22 The partial 16S rRNA for both isolates was 99% similar to S. infantarius subsp. coli JB1 (GenBank accession AF104109), which is consistent with the biochemical and MALDI-based categorizations.…”

Streptococcus bovis/S. equinuscomplex septicemia in a group of calves following intramuscular vaccination

Organisms previously classified as Streptococcus bovis (i.e., the S. bovis/S. equinus complex) are common in cattle feces, but may also act as opportunistic pathogens. In the current work, Streptococcus infantarius subsp. coli, a member of this complex, was associated of a cluster of calves that died within hours of injection with a modified live viral vaccine. Within 12 h of vaccination of 46 calves at a cow/calf operation, 4 calves had died, 3 calves were ill, and 1 unvaccinated cow was dead. Autopsies were performed on the cow, 2 dead calves, and 1 affected surviving calf, which was euthanized ~24 h after vaccine administration. The animals had similar gross anatomic and microscopic lesions, including subcutaneous and intramuscular dark hemorrhage on the caudal neck, multiorgan ecchymosis and petechiation, and alveolitis to interstitial pneumonia. Gram-positive cocci were in the vasculature of the lung and skeletal muscle, and S. infantarius subsp. coli was cultured from tissues and from the vaccines used on affected animals, but not in vials used on unaffected animals. Together, these findings suggest death caused by streptococcal septicemia and toxemia as a result of contamination.

“…Adenomatous polyps are considered as good and few surrogate end point markers for colorectal cancer (Kelly et al, 1989;Nielsen et al, 2007). It would be of interest to substantiate any relationship between bacterial colonic carriage, colonic polyps and the type of polyp and its malignant potential (Boleij et al, 2009a;Schlegel et al, 2003). Contrary to the more commonly reported association between S. bovis/gallolyticus bacteremia and colorectal cancer, a link to pre-neoplastic adenomatous polyps was less frequently reported (Burns et al, 1985;Ellmerich et al, 2000a).…”

“…More precisely, S. bovis biotype I and II/2 isolates were shown to be S. gallolyticus (Devriese et al, 1998). Accordingly, S. bovis biotype I was replaced by S. gallolyticus subspecies gallolyticus and biotype II/2 was replaced by S. gallolyticus subspecies pasterianus and S. gallolyticus subspecies macedonicus (Schlegel et al, 2003). S. gallolyticus subspecies gallolyticus, rather than other related taxa, have been found to be constantly associated with underlying colorectal cancer.…”

Development of a multilocus sequence typing scheme for Streptococcus gallolyticus

et al. 2014

Streptococcus gallolyticus is often found as a member of the normal gut microflora in various animals. However, it has been reported to cause mastitis in cattle, septicaemia in pigeons, and meningitis, septicaemia and endocarditis in humans. However, little is known about the epidemiology and crucial virulence factors of S. gallolyticus. To help address these issues, we developed a multilocus sequence typing (MLST) scheme for S. gallolyticus. Seven housekeeping gene fragments were sequenced from each of 58 S. gallolyticus isolates collected from diverse origins and sources. The MLST scheme had good discriminatory ability. The 63 strains, including the 5 whole genome sequenced strains examined, resolved into 57 sequence types (STs), with 52 STs represented by only a single strain. With respect to the identification of S. gallolyticus subspecies (i.e. S. gallolyticus subsp. gallolyticus, S. gallolyticus subsp. pasteurianus and S. gallolyticus subsp. macedonicus), the results of biochemical tests and DNA-DNA hybridization were in high concordance with those of the MLST scheme. The MLST scheme developed in this study may be a useful tool capable of replacing the conventional methods used for S. gallolyticus subspecies identification. The results of this study suggest that the biology and virulence of two pathogenic S. gallolyticus subspecies (i.e. S. gallolyticus subsp. gallolyticus and S. gallolyticus subsp. pasteurianus) are very different. The MLST scheme offers researchers a valuable typing tool that will promote further investigation of the epidemiology of S. gallolyticus.
