Snapshot A 25-year-old man presents to the emergency room for pain in his right lower quadrant. He was found to have perforated appendicitis and was immediately taken to the operating room for emergent laparoscopic appendectomy. [step1.medbullets.com]
We here present the first case of a metronidazole resistant nimD positive Bacteroides stercoris. The isolate originated from a polymicrobial intra-abdominal abscess in a 70-year-old woman. [ncbi.nlm.nih.gov]

- Plethora
Resistance to multiple antibiotics has been increasing in Bacteroides spp. for decades, and is primarily due to horizontal gene transfer of a plethora of mobile elements. [futuremedicine.com]
Results 3.1 Overview of transporter types The Transporter Classification (TC) system includes a plethora of transport proteins, many of which are characterized both structurally and functionally. [journals.plos.org]

- Constipation
Did you know that if you experience constipation instead of lose stools or feel wired/anxious after taking a high dose of vitamin C, can be a sign of adrenal issues?! [player.fm]

Vertigo is a kind of dizziness that occurs even if you're not doing anything or if you're just making slight movements. [player.fm]

Compared with other sequenced colonic microorganisms such as Bifidobacterium longum and Clostridium perfringens, both Bacteroides species contain much larger numbers of polysaccharide-degrading enzymes with a wide range of substrate specificities (132 [pnas.org]

A 2006 report reviewed cases of infection in prosthetic joints and did find reports of infection with anaerobes, including Clostridium difficile, Clostridium perfringens, Porphyromonas melaninogenica, and Veilonella species, but not Bacteroides species [doi.org]
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
Infections produced by anaerobic microorganisms, such as Bacteroides spp., 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 [revistanefrologia.com]
Etiology
Pouchitis serves as a model for UC with a predictable incidence of disease onset and enables prospective longitudinal investigations of UC etiology prior to inflammation. [ncbi.nlm.nih.gov]

Epidemiology
Analysis of HF183TaqMan (or newer derivatives) is recommended for inclusion in future epidemiological studies concerned with beach water quality, while better concentration techniques are needed for HPyV. [ncbi.nlm.nih.gov]
Epidemiologic Risks Bacteroides spp are the most common organism in the colon at 10 10 –10 11 cells per gram of human feces. To put that into perspective, you are 3.7x10 13 cells. [pusware.com]
ETBF is emerging as an important cause of human diarrheal disease but additional epidemiologic studies are needed to better understand the role of ETBF human disease. [journals.lww.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]
In addition to TLR2 and TLR4 at least one additional microglial transmembrane LPS receptor CD14 mediates phagocytosis of both bacterial components and Aβ42 peptides, hence expanding roles for microglia and microglial LPS receptors in the pathophysiology [frontiersin.org]
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 [doi.org]
