To observe the transfer of the digestive microbiota from sow to piglet, describe the impact of the sow's Salmonella shedding on this transfer and identify transferred populations that could be associated with the future Salmonella status of the piglets.
Salmonella shedding status of 19 sows was determined at the beginning and end of gestation. Four piglets were randomly selected from each sow. Using MiSeq, the microbiotas of the sows at the end of gestation and of their piglets 1 day before weaning were described. Results showed that the Salmonella shedding of the sows, the birth mother, the lairage room, the parity and the contamination of the lairage environment were associated to the microbiota of the piglets (permanova P < 0·05). Several genera were associated with piglets born from negative or positive sows.
There is a link between the microbiota of the sows at the end of gestation and the microbiota of their piglets at weaning, and the Salmonella shedding of the sow is associated with the microbiota of the piglets.
Salmonella status of the sows affects the microbiota of their piglets and could affect the long-term Salmonella colonization resistance of these animals and their health.
观察母猪到仔猪的消化道微生物群转移，描述母猪沙门氏菌脱落对这种转移的影响，并鉴定可能与仔猪未来沙门氏菌状态相关的转移种群。
在妊娠末期和妊娠结束时分别确定了 19 头母猪的沙门氏菌脱落状态。从每头母猪中随机选择 4 头仔猪。使用 MiSeq 描述了妊娠末期母猪及其断奶前 1 天仔猪的微生物群。结果表明，母猪（分娩母亲）、产仔栏、胎次和产仔栏环境的污染与仔猪的微生物群有关（永久方差分析 P<0.05）。一些属与来自阴性或阳性母猪的仔猪有关。
母猪妊娠末期的微生物群与仔猪断奶时的微生物群之间存在联系，母猪的沙门氏菌脱落与仔猪的微生物群有关。
母猪的沙门氏菌状态会影响其仔猪的微生物群，可能会影响这些动物的长期沙门氏菌定植抵抗力及其健康。
