摘要:猪大肠杆菌病是由致病性大肠杆菌或者被称为产毒素的大肠杆菌感染引发的一种肠道传染性疾病,在全球生猪养殖领域广泛发生流行,会对养殖业造成严重的经济损失。防控猪大肠杆菌病,需要猪产毒素大肠杆菌等流行病学诊断方法和防防控手段进行全面的分析。做好注大肠杆菌病的有效诊断,并在进行疾病诊断的基础上筛选出敏感药物进行针对有效的治疗,保障药物选择的科学性、合理性,尽量降低大肠杆菌病的耐药性产生。该文主要论述猪大肠杆菌病的流行特点、临床症状、病理变化、诊断方法,并提出了抗生素治疗手段。

Abstract:Swine colibacillosis is an intestinal disease caused by the pathogenic E. Coli,or toxin producing E. Coli,that is infectious disease in pig farms worldwide,will cause serious economic losses to the aquaculture industry. In order to prevent and control porcine colibacillosis,it is necessary to analyze the methods of epidemiology diagnosis,prevention and control. Do a good job in the effective diagnosis of injected colibacillosis and,on the basis of the diagnosis of the disease,screen out sensitive drugs for effective treatment to ensure that the choice of drugs is scientific and rational,to reduce the drug resistance of E. Coli as far as possible. This article mainly discusses the epidemic characteristics,clinical symptoms,pathological changes and diagnostic methods of porcine colibacillosis,and puts forward the means of antibiotic treatment.
Keywords:porcine intestinal colibacillosis,diagnosis,antibiotic treatment
0引言
大腸杆菌拥有多种血清型,不同血清型的大肠杆菌致病性存在很大,差异性造成猪群发病的只有个别的大肠杆菌。产毒素大肠杆菌是猪肠道大肠杆菌的主要致病菌,由于该类大肠杆菌能引发新生仔猪和断奶仔猪出现严重的腹泻症状,发病率相对较高,并且能够在发病的猪群当中反复周期性的流行,造成高额的治疗成本和防控费用。猪大肠杆菌病的发生流行可带来较高的死亡率,使猪群的增重放缓,治疗成本增加,饲料利用率显著下降,养殖场面临较大的经济损失[1]。预防和控制猪大肠杆菌病常用的措施主要包括减少环境中的大肠杆菌数量,加强环境卫生的有效调控,保障养殖场内外的生物安全,维持适宜的生长环境,通过疫苗免疫接种,确保仔猪能够从母猪的乳汁中获得被动抗体,提高猪群的免疫水平。……
