Streptococcus bovis bacteremia related to colon adenoma in a chronic hemodialysis patient

Abstract

We report the case of a 54-year-old hemodialysis patient who presented with recurrent fever due to Streptococcus bovis bacteremia related to colonic tubulovillous adenoma. Following polypectomy and broad-spectrum antibiotic therapy, the patient totally recovered. In this paper, we discussed the relation between S. bovis bacteremia, colonic adenomas, and hemodialysis. Awareness of this association is critical for early diagnosis and management.

The association of Streptococcus bovis/gallolyticus with colorectal tumors: The nature and the underlying mechanisms of its etiological role

“…The relationship between S. bovis/gallolyticus infection and the progressive development of malignant disease in preneoplastic adenomatous polyps was supported by recent reports [39,73,74]. Interestingly, S. bovis/gallolyticus was found to be mildly associated with some benign lesions (diverticulosis, inflammatory bowel disease, cecal volvulus, perirectal abscess hemorrhoids, and benign polyps), while it was strongly associated with most malignant diseases (cancer and neoplastic polyps) of the colon [2,39,67,70,75,76].…”

Catheter-related bacteremia caused by Comamonas testosteroni in a hemodialysis patient

“…The remaining causes of CRB are a various Gram‐negative bacilli (approximately 30%), and 10% due to mixed infections and fungi 9 . The incidence of CRB in hemodialysis patients due to Gram‐negative bacilli and other unusual microorganisms, such as Serratia spp ., Acinetobacter spp ., Citrobacter spp ., and Agrobacterium radiobacter is increasing 10 . Generally, C. testosteroni infections have a favorable outcome, and the majority of the infected patients recovered after antibiotic therapy and removal of the vascular access device.…”

For example, Le Moel et al reported a case of C. testosterone bacteremia in a 75-year-old woman with breast cancer whose origin was from a central venous catheter (CVC).…”

Molecular characterization of a novel mosaic tet(S/M) gene encoding tetracycline resistance in foodborne strains of Streptococcus bovis

“…Several Streptococcus species represent serious invasive pathogens, often associated with wound infections, sepsis, abscesses and dental caries in immunocompromised or cancer patients (Moet et al , 2007; Fernández-Ruiz et al , 2010; Al-Jashamy et al , 2010). The association of S. bovis with endocarditis (Gupta et al , 2010), colon cancer (Boleij et al , 2009) and colon adenoma (Kahveci et al , 2010) has also recently been reported. This species is therefore considered a potential pathogen.…”
