Abstract

Dietary intake of probiotic yogurt, which has beneficial effects on intestinal microecology, is associated with a lower incidence of hypertension. Recent studies have shown that the gut microbiota plays a vital role in the development of hypertension. However, the impact of the gut microbiota in the antihypertensive effect of probiotic yogurt remains unclear. Here, we evaluated the impact of the gut microbiota in the antihypertensive effect of probiotic yogurt in spontaneously hypertensive rats (SHR). SHR were treated with probiotic yogurt (0.2 mL per 100 g body weight) (SHR-Y group) for seven weeks and compared with whole milk-treated (0.2 mL per 100 g body weight) SHR (SHR group) and with normotensive Wistar-Kyoto rats (WKY group). The blood pressure and heart function of the rats in the WKY, SHR, and SHR-Y groups were measured. Fecal microbiota was assessed by 16S ribosomal RNA (16S rRNA) gene sequencing. To investigate whether probiotic yogurt prevents hypertension in spontaneously hypertensive rats through the gut microbiota, we co-housed SHR rats (SHR
