We assessed in a piglet model the relationship between fecal ciprofloxacin concentrations and ciprofloxacin-resistant Enterobacteriaceae counts. Twenty-nine piglets were orally treated with placebo or with 1.5 or 15 mg ciprofloxacin/kg of body weight/day from day 1 (D1) to D5. Areas under the curve (AUC) of concentrations increased sharply with dose and correlated positively with AUC of resistant bacteria log counts between D1 and D9. Removing residual colonic quinolones could help to control the emergence of resistance in fecal flora.

Usefulness of Novel Image-Enhanced Endoscopy for Predicting Maintenance of Clinical Remission in Ulcerative Colitis.

Dig Dis Sci

January 2025

Department of Gastroenterology, Graduate School of Medicine, Chiba University, 1-8-1 Inohana, Chuo-Ku, Chiba, 260-8670, Japan.

Purpose: The performance of endoscopic evaluation of ulcerative colitis (UC) using conventional scoring, including Mayo endoscopic subscore (MES) and ulcerative colitis endoscopic index of severity (UCEIS), is not satisfactory. Recently, the usefulness of novel image-enhanced endoscopy (IEE) such as texture and color enhancement imaging (TXI) and red dichromatic imaging (RDI) has been reported in the endoscopic evaluation of UC. We evaluated the performance of IEEs in UC, particularly focusing on the correlation with MES and UCEIS, and prediction of relapse.

Electronic address:

Objectives: Faecal microbiota transplantation (FMT) is an established treatment for recurrent Clostridioides difficile infection (R-CDI). This study aimed to identify calprotectin and microbiome characteristics as potential biomarkers of FMT success.

Methods: We conducted a prospective study of patients who underwent oral FMT (single dose of 4-5 capsules) for R-CDI (January 2018 to December 2022).

Fucoidan exerts antitumor effects by regulating gut microbiota and tryptophan metabolism.

Int J Biol Macromol

January 2025

State Key Laboratory of Marine Food Processing & Safety Control, College of Food Science and Engineering, Ocean University of China, China.

Fucoidan, a water-soluble polysaccharide derived from marine organisms, has garnered significant attention for its ability to regulate gut microbiota and its anti-tumor properties. However, the existence of a correlation between the anti-tumor effect of fucoidan and its regulation of the gut microbiota remains unknown. In pursuit of this objective, we culled the gut microbiota of mice with broad-spectrum antibiotics to generate pseudo-sterile tumor-bearing mice.

A High Fat, High Sugar Diet Exacerbates Persistent Post-Surgical Pain and Modifies the Brain-Microbiota-Gut Axis in Adolescent Rats.

Department of Neuroscience, Monash University, Melbourne, VIC, Australia; Gastroenterology, Immunology, Neuroscience (GIN) Discovery Program. Electronic address:

Persistent post-surgical pain (PPSP) occurs in a proportion of patients following surgical interventions. Research suggests that specific microbiome components are important for brain development and function, with recent studies demonstrating that chronic pain results in changes to the microbiome. Consumption of a high fat, high sugar (HFHS) diet can drastically alter composition of the microbiome and is a modifiable risk factor for many neuroinflammatory conditions.
