“…We have already reported that growing male mice exhibit vigorous coprophagy [3]. In the present study, pregnant or lactating females were also seen to exhibit vigorous coprophagys, suggesting that this activity accelerates when nutritional requirements are elevated, i. e., during growth, pregnancy or lactation.…”

“…The diurnal pattern of coprophagy was identical to that observed in male mice [3]. That is, coprophagy was frequently observed during the first half of the light phase, tended to decrease thereafter, and increased again toward the time of lighting.…”

“…2) Lifelong coprophagy in male mice : Changes in coprophagy with age were investigated in male mice throughout their life span [8]. Sucklings exhibited coprophagy at age 17 to 18 days, i. e., a few days after they began to excrete feces autonomously.…”

“…Ultimately, this change in eating behavior could also influence host physiology. Reduced coprophagy may not only affect the migration of fecal microbes into the gut but could limit nutrient intake such as vitamin B12 and folic acid that are beneficial to the host wellbeing [30,31].…”

Dietary changes are known to alter the composition of the gut microbiome. However, it is less understood how repeatable and reversible these changes are and how diet-switches affect the microbiota in the various segments of the gastrointestinal tract. Here, a treatment group of conventionally raised laboratory mice is subjected to two periods of western diet (WD) interrupted by a period of standard diet (SD) of the same duration. Beta-diversity analyses show that diet-induced microbiota changes are largely reversible (q = 0.1501; PERMANOVA, weighted-UniFrac comparison of the treatment-SD group to the control-SD group) and repeatable (q = 0.032; PERMANOVA, weighted-UniFrac comparison of both WD treatments). Furthermore, we report that diet switches alter the gut microbiota composition along the length of the intestinal tract in a segment-specific manner, leading to gut segment-specific Firmicutes/Bacteroidota ratios. We identified prevalent and distinct Amplicon Sequencing Variants (ASVs), particularly in genera of the recently described Muribaculaceae, along the gut as well as ASVs that are differentially abundant between segments of treatment and control groups. Overall, this study provides insights into the reversibility of diet-induced microbiota changes and highlights the importance to expand sampling efforts beyond the collections of fecal samples to characterize diet-dependent and segment-specific microbiome differences.
