Intestinal lymphangiectasia (IL) is a common complication in dogs. This study analyzed intestinal microbiota using 16S rRNA amplicon analysis as candidate factors that strongly influence the small intestinal lymphatic vessels in dogs with and without IL. Twelve dogs were included, of which six were diagnosed with lymphoplasmacytic enteritis, four with small-cell lymphoma, and two with large-cell lymphoma. Seven of these dogs had IL, whereas five did not. First, the microbial diversity analyzed by Faith pd index was significantly decreased in dogs with IL compared to dogs without IL. Then, the relative amounts of each bacterial taxa were compared between dogs with and without IL using Linear discriminant analysis effect size analysis. At the genus level, the Ruminococcus gnavus groupsignificantly increased in dogs with IL compared to dogs without IL. A total of four genera, including Ruminococcus torques group and Faecalibacterium, which produce butyrate, significantly decreased in dogs with IL. This study showed decreased intestinal bacterial diversity and several alterations of intestinal microbiota, including a decrease in butyrate-producing bacteria in dogs with IL, compared to dogs without IL.

A double-blind, placebo-controlled, randomized trial was conducted to investigate the beneficial effect of probiotic and prebiotic fermented milk on the skin of healthy adult women. Forty healthy Japanese adult female volunteers with healthy skin randomly received either a bottle of probiotic and prebiotic fermented milk containing Bifidobacterium breve strain Yakult and galacto-oligosaccharides (GOS) (active group) or a non-fermented placebo milk containing neither probiotics nor GOS (placebo group) daily for 4 weeks. Before and after intake, hydration levels and cathepsin L-like activity in the stratum corneum and phenol levels in the serum and urine were determined. After intake, the hydration level of the stratum corneum decreased significantly in only the placebo group and was significantly lower than in the active group (p=0.031). Cathepsin L-like activity, an indicator of keratinocyte differentiation, was significantly increased in the active group (p=0.027). Serum and urine phenol levels decreased significantly in the active group (p=0.014, p=0.002, respectively), and serum phenol levels were significantly lower in the active group compared with the placebo group (p=0.006). The consecutive intake of probiotic and prebiotic fermented milk can benefit skin condition without dryness and decrease the levels of phenol production by gut bacteria in healthy adult women.
