摘要: 羔羊腹泻是一种常发生于新生和断奶阶段,且能够导致羔羊生长迟滞甚至死亡的消化道疾病。粪菌移植(fecal microbiota transplantation,FMT)技术在反刍幼畜消化道疾病防治上鲜有研究。本研究采用FMT对腹泻羔羊进行治疗并与不同抗生素药物治疗进行对比,探索FMT对吮乳期羔羊腹泻的治疗效果。试验选择日龄(24±2)d、体重(6.12±1.01)kg、临床散发的具有典型腹泻症状的吮乳期羔羊60只(公母各半)以及健康羔羊10只(公母各半),分为健康对照组(HC)、腹泻对照组(SC)、粪菌移植治疗组(FMT)、庆大霉素治疗组(GM)、恩诺沙星治疗组(ENR)、庆大霉素+粪菌移植治疗组(GM+FMT)以及恩诺沙星+粪菌移植治疗组(ENR+FMT),测定腹泻羔羊腹泻治愈天数、日增重以及羔羊生理生化指标及相关炎性因子指标。结果表明:1)腹泻羔羊平均日增重、红细胞数量、血红蛋白含量、淋巴细胞比例和肌酐浓度均显著低于健康对照组羔羊(P<0.05),而平均血红蛋白浓度和炎性因子均显著高于健康对照组(P<0.05);2)与SC组相比,经过5种方法治疗,除GM+FMT组外,FMT、ENR、ENR+FMT和GM组均显著降低治愈天数(P<0.05)。ENR组还显著提高腹泻羔羊日增重(P<0.05);3)与SC组相比,FMT治疗可显著提升腹泻羔羊血液中血红蛋白含量和血液淋巴细胞数量(P<0.05);4)经FMT、ENR和GM+FMT治疗后,各种炎性因子均显著下降到健康组羔羊水平。结果表明,FMT能够有效治愈羔羊腹泻症状,血液生理生化功能得到改善,抑制了炎性反应,显著降低腹泻率。FMT有望作为一种抗生素替代方法应用于羔羊腹泻防治实践。

Abstract: Lamb diarrhea is one of the common gastrointestinal diseases during the newborn and weaning stage that can result in lamb's growth retardation and even death. Fecal microbiota transplantation (FMT) has little been applied on the prevention and treatment of digestive tract diseases in young ruminants. In this study, FMT was used to treat diarrhea lambs with the comparison by using different antibiotics so as to explore the therapeutic effect of FMT on suckling lambs' diarrhea. Sixty suckling lambs (male and female in half) with significant clinical symptoms of diarrhea and 10 healthy lambs (male and female in half) at the age of (24±2) days and body weight of (6.12±1.01) kg were divided into 7 groups, namely, healthy control (HC), saline control (SC), fecal microbiota transplantation (FMT), gentamicin (GM), enrofloxacin (ENR), gentamicin+FMT (GM+FMT) and enrofloxacin+FMT (ENR+FMT) treatment, with 10 lambs each. The healing time (day), average daily gain (ADG), physio-biochemical indexes and the diarrhea related inflammatory factor markers were measured. The results showed: 1) ADG, RBC, HGB, the percentage of lymphocyte and the concentration of serum creatinine (CREA) in SC group were all significantly lower than those of HC group (P<0.05), whereas the MCHC and inflammatory factors in SC group were significantly higher than those of HC group (P<0.05). 2) Compared with SC group, after 5 methods of treatment, the FMT, ENR, ENR + FMT, and GM groups all significantly reduced the healing time (P<0.05) except for the GM + FMT group. Only after ENR treatment the ADG was significantly increased (P<0.05). 3) In comparison with SC group, FMT treatment significantly increased the blood hemoglobin content (HGB) and blood lymphocyte number (P<0.05). 4) After FMT, ENR and GM+FMT treatment the inflammatory factors measured were all significantly declined to the level as that in healthy lambs (P<0.05). It is indicated that FMT could treat the lamb's diarrhea effectively by shortening the healing time, improvement of physio-biochemical statues and the inhibition of inflammation in diarrheic lambs. FMT could be an alternative way of lambs' diarrhea treatment by antibiotics in practice.
