Bacteroides


Presentation

  • We present the first report of pylephlebitis with Bacteroides bacteremia associated with underlying Strongyloides stercoralis infection and briefly review the management of septic portal vein thrombosis.[ncbi.nlm.nih.gov]
Splenomegaly
  • Computerized axial tomography revealed left sided free flowing pleural effusion and splenomegaly with liquefaction and possible gas formation. The splenic fluid grew an unusual organism known as Bacteroides distasonis.[ncbi.nlm.nih.gov]
Dog Bite
  • We describe a case of bloodstream infection caused by Bacteroides denticanum that probably originated from a dog bite. MALDI-TOF MS misidentified this new species as B. pyogenes.[ncbi.nlm.nih.gov]
  • B. fragilis was isolated from one patient with a dog bite and from one patient with a cat bite, and B. ovatus was isolated from one patient with a dog bite ( 272 ). Endocarditis and pericarditis.[cmr.asm.org]
Splenectomy
  • The patient received antimicrobial therapy and underwent a splenectomy with full recovery. The spleen was cystically infarcted and measured 22 x 16 x 5 cm. The capsule was thickened and covered by fibrinous exudate.[ncbi.nlm.nih.gov]
Pleural Effusion
  • Computerized axial tomography revealed left sided free flowing pleural effusion and splenomegaly with liquefaction and possible gas formation. The splenic fluid grew an unusual organism known as Bacteroides distasonis.[ncbi.nlm.nih.gov]
Chest Pain
  • The presence of fever and left sided pleuritic chest pain in patients with sickle cell disease should raise the suspicion of splenic abscess.[ncbi.nlm.nih.gov]
Low Back Pain
  • Abstract A 35-year-old, previously healthy female presented with severe low back pain, fever, and a high erythrocyte sedimentation rate 1 week after a routine dental cleaning.[ncbi.nlm.nih.gov]
Back Pain
  • Abstract A 35-year-old, previously healthy female presented with severe low back pain, fever, and a high erythrocyte sedimentation rate 1 week after a routine dental cleaning.[ncbi.nlm.nih.gov]
Eczema
  • Skin and soft tissue infections Infections involving AGNB include superficial infections, such as infected cutaneous ulcers, cellulitis, secondary diaper rash, gastrostomy or tracheostomy site wounds, infected subcutaneous sebaceous or inclusion cysts, eczema[web.archive.org]
Formication
  • The major end products of glucose fermentation were acetic acid, lactic acid and formic acid. DNA-DNA hybridization data indicated that two isolates, YS-aM39 T and R2F3-3-3 T , represent a species distinct from B. ovatus and B. xylanisolvens.[ncbi.nlm.nih.gov]

Treatment

  • Analysis of k calculated from the 10 experimental treatments indicated that k is more highly correlated to temperature than initial Bacteroides 16S rRNA gene starting concentrations.[ncbi.nlm.nih.gov]
  • Oral metronidazole was added to the treatment regimen, in accordance with the antibiogram. An abdominal computerised tomography (CT) showed no abdominal pathologies.[revistanefrologia.com]
  • Our data show that several genes are differentially expressed after BFT treatment and these changes correlate with changes in chromatin accessibility.[biorxiv.org]

Prognosis

  • . , generally indicate a subjacent abdominal pathology and involve a poor prognosis. 1-4 Here we describe the case of a 46-year-old male with a case of peritonitis caused by Bacteroides thetaiotaomicron produced two month after starting continuous ambulatory[revistanefrologia.com]

Pathophysiology

  • Pathophysiology Most infections due to AGNB originate from the endogenous mucosal membrane florae. Knowledge of the common mode of distribution allows for a logical choice of antimicrobial therapy for infections in these sites.[web.archive.org]
  • Pathophysiology Although AGNB perform beneficial functions as part of the GI flora, they are also consummate opportunistic pathogens that can cause serious infections, typically in synergistic infections in combination with other anaerobic as well as[emedicine.medscape.com]
  • Prospecting for these chemicals and characterizing the signaling pathways through which they operate may provide new strategies and reagents for manipulating our biology in ways that enforce health or that correct or at least ameliorate certain pathophysiologic[pnas.org]
