Metabolic studies were performed before and seven days after treating rats orally with lincomycin. Following the treatment the mean faecal weight increased from 302.2 g/72 hr +/- 3.8 (S.D.) to 65.5 +/- 8.2. The faecal fat excretion was unchanged, and the weight increase was mainly due to increased water content. To find whether the watery diarrhoea was due to bile acid malabsorption, the absorption rate of [14C]-taurocholic acid was measured in untreated rats and rats treated with lincomycin using an in vivo perfusion technique. There was no significant difference in bile acid absorption rate measured at three different concentrations of bile acid in the perfusate. Alternative mechanisms of lincomycin-associated diarrhoea are discussed.

Unlabelled: Members of the gut microbiome encounter a barrage of host- and microbe-derived microbiocidal factors that must be overcome to maintain fitness in the intestine. The long-term stability of many gut microbiome strains within the microbiome suggests the existence of strain-specific strategies that have evolved to foster resilience to such insults. Despite this, little is known about the mechanisms that mediate this resistance.

Cognitive dysfunction is common in major depressive disorder (MDD), but whether bile acids impact these networks in MDD patients is unknown.
Methods: Resting state functional magnetic resonance imaging (fMRI) scans and blood measures of four bile acids from 74 treatment-naïve adults with MDD were analyzed.

Changes in the gut microbiota are associated with obesity and may influence weight loss. We are currently implementing a sustained multidisciplinary collaborative weight management (MCWM) approach to weight loss. We report significant improvements in participant health status after 6 months, along with alterations in the structure, interactions, and metabolic functions of the microbiota.

Background: The Kasai portoenterostomy (KPE) aims to re-establish bile flow in biliary atresia (BA); however, BA remains the commonest indication for liver transplantation in pediatrics. Gut microbiota-host interplay is increasingly associated with outcomes in chronic liver disease. This study characterized fecal microbiota and fatty acid metabolites in BA.
