“…Ethanol-induced liver injury increased the relative abundance of Butyricimonas spp., which positively correlated with the levels of liver injury parameters such as AST and ALT (36). The species B. virosa has been reported to be associated with bacteremia (37)(38)(39). We also found that Oscillibacter spp.…”

Acute liver failure is a severe liver disorder that poses considerable global challenges. Previous studies on Bifidobacterium longum R0175 have mainly focused on its psychotropic functions. The current research focused on the protective efficacy of B. longum R0175 against acute liver failure caused by d-galactosamine (d-GalN) in rats and further tested the hypothesis that B. longum R0175 exerted liver-protective effects by affecting the intestinal microbiota and fecal metabolites and by inhibiting inflammation. We found that oral gavage of B. longum R0175 markedly reduced the severity of liver injury in d-GalN-treated rats, as evidenced by decreased serum levels of aspartate aminotransferase (AST) and total bile acids (TBAs) (P < 0.05). Moreover, the plasma concentrations of proinflammatory cytokines (interleukin 1β [IL-1β] and tumor necrosis factor-α [TNF-α]) and chemokines (granulocyte-macrophage colony-stimulating factor [GM-CSF], macrophage chemoattractant protein 1 [MCP-1], chemokine [C-X-C motif] ligand 1 [CXCL1], chemokine [C-C motif] ligand 5 [CCL5], and macrophage inflammatory protein-1α [MIP-1α]) were also markedly reduced (P < 0.05). Pretreatment with B. longum R0175 partially reversed the gut microbiota dysbiosis in rats with liver injury by increasing the relative abundances of potentially beneficial bacteria, such as Alloprevotella spp., and decreasing the relative abundances of potentially harmful bacteria, such as Acetatifactor muris, Butyricimonas spp., and Oscillibacter spp. Furthermore, B. longum R0175 administration partially improved the metabolic function of the intestinal microbes, as indicated by the decreased level of lithocholic acid found in the feces. IMPORTANCE Our research investigated the protective and preventive roles of B. longum R0175 in a rat model of acute liver failure. The results illustrated that this probiotic strain exhibited protective effects in rats with acute liver failure. Thus, B. longum R0175 showed clinical application prospects that required further exploration.

“…The second case was described by Mehta et al . [4] in an 81-year-old male veteran who developed fever 18 days after a Whipple procedure for adenocarcinoma of the duodenum [4] . Gram-negative bacilli were isolated from the anaerobic blood culture bottle after 5 days of incubation and confirmed to be B. virosa by MALDI-TOF MS.…”

“…Butyricimonas virosa is a prevalent inhabitant of the intestine [1,5]. Few cases of human cases of infection due to B. virosa have been reported in literature [2][3][4][5][6], all of which were bacteremia cases, and three of them were associated with gastrointestinal tumors. On the case we report, the patient had an advanced colon malignancy (see Table ).…”

“…B. virosa species exhibits additional characteristics: it produces a catalase, and gelatin is not digested in the cultures. Besides, B. virosa is the only pathogenic species within the recently described genus Butyricimonas [2], and has been associated with digestive pathology [2][3][4][5].…”

In the present document, we describe the case of bacteremia caused by Butyricimonas virosa (B. virosa), the first reported in Spain, occurred in a patient affected by colon adenocarcinoma. The literature is reviewed and we summarize the characteristics of the previously described cases, pointing out the fact that B. virosa is closely related to intra-abdominal pathology, especially with gastrointestinal malignancy.
