Description
技术领域
本发明属于微生物技术领域,尤其涉及一株嗜酸乳杆菌及其应用。
背景技术
目前,炎症性肠病(Inflammatory bowel disease,IBD)是一种肠道慢性非特异炎症性疾病,其临床表现为腹泻和血便,其特征是病程有进行性和不可预知性。溃疡性结肠炎是结肠黏膜的一种特发性的慢性炎症性疾病,始于直肠,通常以连续的方式向近端延伸穿过部分或整个结肠。临床表现多以腹泻、腹痛、黏液浓血便等症状为主,其中血性腹泻是该疾病的典型症状。
肠道菌群的改变与炎症性肠病的发生发展密切相关,一方面,肠道菌群的紊乱可能导致肠粘膜环境改变和粘膜炎症的发生。
益生菌是用来改善微生物平衡的非致病微生物,特别是在胃肠道。它们由布氏酵母菌或乳酸菌组成,作为膳食补充剂和食品受到监管。许多益生菌来自健康人体肠道中的共生微生物区系;其中几个与IBD有关。大量文献证实了益生菌的抗炎作用,而益生菌又反映了宿主与其微生物群之间存在的免疫耐受性。益生菌通过产生细菌素来抑制潜在致病菌的生长,并创造一个酸性更强的环境,这种环境对致炎细菌有害,但促进有益物种的生长,从而有益地调节微生物区系的组成。以达到增加益生菌多样性,减少真菌多样性,还可以促进具有抗炎和抗癌特性的脂肪酸的产生。近年来,益生菌在溃疡性结肠炎中的作用的几项研究表明,益生菌可以缓解疾病的严重程度。这种效果在益生菌中不是普遍性的,具有菌株特异性。
通过上述分析,现有技术存在的问题及缺陷:目前还未有相关的能够起到很好预防、调节或治疗作用的益生菌。
解决以上问题及缺陷的难度为:益生菌种类繁多,在不同的乳杆菌菌株之间存在着巨大的基因组多样性。对多种益生菌的体外测定和动物模型数据表明,不同的潜在益生菌菌株的药效不同。不同的益生菌因菌株和疾病特异性不同,对不同的疾病有不同的作用。要从众多来源中分离鉴定挑选出一株对UC有良好缓解和治疗作用的菌株,需要经过繁杂的培养筛选工作才可能找到特异性治疗UC的菌株并且需要通过反复多样的实验来验证该菌株的效力。
解决以上问题及缺陷的意义为:益生菌作为定植于肠道并对肠道环境发挥调节作用的肠道菌群,与肠道疾病有着密切的联系。目前较为广泛的治疗UC的方法包括氨基水杨酸、激素和免疫抑制剂,这三种药物对UC的治疗作用较局限且副作用较多,更多的新疗法有待提出。有研究发现双歧杆菌能够协同美沙拉嗪治疗改善UC患者的临床症状,其效果要优于美沙拉嗪单独治疗,说明益生菌对UC的治疗具有潜在的研究价值。因此迫切需要开发一种有效的益生菌来预防和治疗UC。

(5)对模拟胃肠液具有较好的耐受能力。
(6)对嗜酸乳杆菌C4的生化鉴定结果如表1。
表1嗜酸乳杆菌C4生化鉴定结果
本菌株嗜酸乳杆菌C4的获得方法为:
(1)取1g来自4岁孩童的新鲜粪便溶于1ml的生理盐水中,稀释1000倍后;
(2)采用四区划线法将稀释液接种至含碳酸钙的MRS培养基中37℃培养36-48h;
(3)选有钙溶圈现象并且符合乳酸菌目基本形态的单菌落进行平板划线纯化,筛选分离出乳酸菌;
(4)将上述单菌落培养于液体MRS培养液中培养24h后进行革兰氏染色,选取革兰氏阳性菌进行后续试验。
CaCO3-MRS培养基:MRS培养基+0.3%CaCO3。
实施例1:嗜酸乳杆菌C4对模拟胃肠液具有良好的耐受性
将冷冻保存的嗜酸乳杆菌C4接种于MRS固体培养基中,在温度37℃厌氧培养36-48h,再经MRS固体培养基传代培养2~3次后,取单个菌落接种于液体MRS培养基中培养24-36h,之后分别取1mL嗜酸乳杆菌C4的培养液,与9.0mL pH=2.5的MRS和MRS培养基混合,并在37℃下厌氧培养3h后取出,稀释1*105后涂布100ul于MRS固体培养基上,厌氧培养48h后取出,平板菌落计数,测定活菌数并计算其存活率(见表2)。
表2嗜酸乳杆菌C4抗酸能力测定
MRS平板菌落计数 | PH=2的MRS平板菌落计数 | 存活率(100%) |
1.4*10<sup>8</sup>CFU/ml | 3.5*10<sup>7</sup>CFU/ml | 25% |
分别取1mL嗜酸乳杆菌C4的培养液,与9.0mL含0.3%牛胆盐的MRS和MRS培养基混合,并在37℃下厌氧培养3h后取出,稀释1*105后涂布100ul于MRS固体培养基上,厌氧培养48h后取出,平板菌落计数,测定活菌数并计算其存活率(见表3)。
存活率=牛胆盐或pH=2MRS处理后平板活菌计数/MRS平板活菌计数*100%
表3嗜酸乳杆菌C4扛胆盐能力测定
实验结果如表2和表3所示。结果表明,嗜酸乳杆菌C4有较好的抗酸和扛胆盐能力。
实施例2:嗜酸乳杆菌C4对UC小鼠结肠缩短的影响
24只C57雄性小鼠(5周,14-16g)随机分为4组,每组6只,分别为:对照组、模型组、美沙拉嗪(5-ASA)组(75mg/kg/day)和嗜酸乳杆菌C4组。在实验期间,除NC组外,其他实验组给予2.5%DSS连续8天饮水诱导小鼠UC模型,造模同时,对各治疗组进行相应药物和细菌灌胃,每天1次,连续8天。灌胃菌悬液的剂量为1.0×109CFU/mL,重悬于PBS溶液中。具体实验动物分组及处理方法见下:
对照组:不作任何干预
DSS组:2.5%DSS水+200ulPBS
C4组:2.5%DSS水+200ulC4菌悬液(1*109CFU/mL)
美沙拉嗪组:2.5%DSS水+200ul美沙拉嗪(5-ASA)(75mg/kg/day)
造模期间(DSS处理),每天定时称量小鼠体重;此外,每日观察小鼠的粪便性状、便血性状和体重变化情况,计算得出小鼠的疾病活动指数(Disease activity index,DAI),具体评分项目的得分如表4。在第9天解剖小鼠,取其结肠并测量结肠长度(图3),并计算小鼠的体重变化率(图4)和DAI评分(图5)。
表4疾病活动指数(Disease activity index,DAI)
实验结果如图3所示。DSS组小鼠结肠长度明显缩短,而C4和5-ASA组的结肠缩短现象有回升,尤其是C4组长度最长。说明嗜酸乳杆菌C4对溃疡性结肠炎的结肠损伤有缓解作用,如图3。DSS组小鼠体重下降明显,从第一天到第九天C4和5-ASA组的体重下降现象有缓解,尤其是C4组体重反而出现增长;且DSS组的DAI评分显著升高,而C4和5-ASA组较DSS组都有下降,其中C4组下降最显著。说明嗜酸乳杆菌C4对溃疡性结肠炎有缓解修复作用,如图4,图5。
实施例3:嗜酸乳杆菌C4对UC小鼠肠道组织损伤的影响
将小鼠颈椎脱白处死后,取适量长度小鼠结肠组织,用PBS冲洗肠道内容物,然后将其浸泡于4%多聚甲醛过夜固定;
将固定后的组织依次浸入85%乙醇,90min,95%乙醇,40min,2次,无水乙,15min,3次,二甲苯,10min,2次。;
将脱水后的组织放入54-56℃的液体石蜡中,30min,2次。;
将组织块放入82℃硬蜡+蜂蜡包埋,然后用切片机切成4um厚的蜡片,最后70℃,45min把蜡片烤干。
HE染色步骤:(1)脱蜡入水:将依次放入2次二甲苯中,每次10分钟,然后依次放入无水乙醇1、无水乙醇2、95%乙醇、90%乙醇以及80%乙醇的梯度酒精中进行脱蜡,每个梯度脱蜡时间为2min,然后流水冲洗2min。
(2)Harris苏木素染色5min,水洗1min。(3)1%盐酸酒精分化数秒。(4)切片流水冲洗15min返蓝。(5)伊红染色1min,流水冲洗2min。(6)染色完成的切片经过80%酒精、90%酒精、95%酒精1、95%酒精2、无水乙醇1、无水乙醇2梯度酒精脱水,每个梯度酒精脱水时间为2min。(7)依次经过二甲苯1、二甲苯2、二甲苯3透明,每次透明时间2min。(8)中性树胶封固,待树胶凝固后,进行显微镜观察。
通过对结肠组织进行HE染色可以看出(图6),DSS组结肠炎细胞浸润严重,已侵至黏膜下层,杯状细胞缺失、隐窝肿胀变形破坏,结肠黏膜完整性被破坏,结肠出现明显的炎症。而control、C4和5-ASA组小鼠结肠黏膜上皮细胞完整,固有层腺体形态正常,隐窝正常,黏膜下层无水肿。说明嗜酸乳杆菌C4对溃疡性结肠炎引起的结肠炎者有缓解作用。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,都应涵盖在本发明的保护范围之内。
