作为检验科的微生物实验室,传统的培养技术不能丢,培养及药敏鉴定结果是医生手中的指挥棒,检验与临床需要密切配合,及时沟通,临床医生需要检验结果的支持和鉴别,才能早期快速准确的诊断疾病。

前言

猪链球菌(Streptococcussuis,SS)是一种革兰阳性链球菌,可导致猪脑膜炎、败血症、关节炎及心内膜炎等,甚至急性死亡[1],也是重要的人兽共患病原菌,能通过人的伤口、呼吸道等部位感染人体,引起人脑膜炎、败血症、关节炎、心内膜炎和眼内炎[2]等,其特点是起病隐匿、进展迅速、病情危重、病死率高[3]。随着养殖产业的发展,猪群养殖规模不断扩大下,猪链球菌病的发生率也在随之上涨[4]。

世界动物卫生组织已将猪链球菌病列为B类疫病,我国将其列为二类动物疫病,也是其他法定监测的传染病之一。在我国,该病以散发为主,偶有暴发(1998年江苏省和2005年四川省曾发生暴发)[5]。因此,早期发现病原,及时治疗是降低病死率的关键。现对本院1例心内膜炎型人感染猪链球菌病病例的诊疗经过、临床特征和治疗及转归进行分析。

案例经过

患者,男,68岁,患者2022年2月12日因过劳操作出现腰部胀痛、乏力、双下肢水肿,来我院肾内科门诊就诊,门诊血常规示血红蛋白 91 g/L,遂以“中度贫血”收入血液科。患者13天前无明显诱因出现乏力、腹部胀痛,伴干咳、白色泡沫样痰,无明显头痛、恶心、呕吐,无胸闷、胸痛、肉眼血尿,无腹痛、腹泻、黑便、血便,无发热、皮疹、关节肿痛等。于当地卫生院治疗后(具体不详),下肢水肿消失,腰痛、乏力无明显好转,遂来我院。

检验案例分析

患者血常规:WBC:10.38×109/L,NEU%:80.60%,NEU#:8.37×109/L,hsCRP:72.14mg/L,PCT:0.171ng/ml,提示严重的炎症感染,结合患者后续出现了发热症状,建议临床送检血培养,2022.2.16日患者血培养需氧及厌氧培养液涂片镜检可见革兰阳性球菌生长,提示G+球菌生长,考虑败血症,予以抗感染治疗。该细菌在血琼脂培养表面长出圆形凸起、表面光滑、边缘湿润的灰白色菌落,菌落周边可见溶血环,结合培养特性及质谱分析最终鉴定为猪链球菌,细菌菌落形态如下图

知识拓展

猪链球菌是一种无鞭毛、无芽孢、有荚膜的革兰氏阳性菌,其形态呈卵圆形、圆形,在显微镜下呈链状排列。猪链球菌除了感染生猪外,牛、羊、家禽等动物及饲养员也均可感染[6]。定植部位为猪的上呼吸道,尤其是扁桃体和鼻腔。可在感染猪链球菌后出现发热、乏力、腹胀、腹泻等症状,严重者可出现败血症、感染性心内膜炎、脑膜炎甚至死亡。感染人群多为饲养员及屠宰场工人或卖猪个体户等[7]。传播途径:猪同类之间的传播可以是呼吸道传播、消化道、生殖道及母婴传播,其中也可通过病鼠传播,也有相关研究表明鸟类也起了传播媒介的作用。人感染猪链球菌多有与猪有密切接触史,其中伤口和消化道是重要的感染渠道。本例患者有职业接触史、皮肤破损史,病猪通过破损的皮肤感染患者。一般情况下病程短,病程较长病例可持续3-5d,主要为突发症状,发生在猪链球菌病流行的初期。急性败血型猪链球菌病的发病率较低,一般为20%~40%,但死亡率高达80%。因此应引起重视。

猪链球菌可通过动物粪便、分泌物等污染饲料、饮水,并能通过接触和蚊虫传播的细菌性疾病,因此在生猪养殖及屠宰过程中必须做好卫生清洁和人、车、料进出场管理。日常要加强猪舍用具、猪舍内部的清洁,定期进行消毒,切断病原传播途径,接触猪时还应戴手套若发现有发病猪只,要在第一时间对其进行隔离,应在药敏试验的基础上应用抗生素治疗,以防因耐药性出现导致治愈率低的问题。

案例总结

本案例患者起病隐匿,以乏力、腰痛、贫血为首发症状,入住血液科,按照血液病治疗,经过骨穿及相关检验检查指标,逐步排除血液病,检验结果提示炎症感染较重,提醒临床进行血培养检查,患者通过血培养检出革兰阳性球菌,将革兰氏染色后的病原菌置于显微镜下观察,发现紫色的圆形或卵圆形成对或短链排列、单个存在的圆形球菌,经过质谱最终鉴定为猪链球菌,通过药敏试验为临床提供了正确的用药指导。

猪链球菌病是一种人畜共患病,在猪养殖业中经常会出现,不仅危害猪只的生长,也会威胁人体健康。近些年,链球菌病的发病率逐渐升高,在一定程度上增加了防控和治疗的难度[8]。猪链球菌病的传播速度快,对猪只的生长危害较大,近年来不断有人感染猪链球菌病例报道,临床医生在接诊患者时,对有职业暴露及疫畜接触史的病人应加强猪链球菌的意识,及时与检验科密切沟通,通过细菌培养等手段,协助准确及时诊断疾病,对患者治疗至关重要。

专家点评

近年来,人感染猪链球菌病例随着现在检测技术不断提高检出率逐渐增多,正确快速的诊断至关重要,本例患者以腰疼、乏力、贫血入院,辗转血液科、感染科及心内科多个科室治疗、检测,最终经过检验科的细菌鉴定,明确诊断,诊断离不开检验工作人员的检测技术,虽然分子诊断迅速崛起,一代测序技术和二代测序等技术都受到了广泛的重视和关注,但是作为检验科的微生物实验室,传统的培养技术不能丢,培养及药敏鉴定结果是医生手中的指挥棒,检验与临床需要密切配合,及时沟通,临床医生需要检验结果的支持和鉴别,才能早期快速准确的诊断疾病,后期的药敏试验也为临床医生合理用药奠定坚实基础。(尹琼,主任医师,天门市第一人民医院心内科主任)
