牛沙门氏菌病防控

Prevention and Control of Bovine Salmonellosis

牛沙门氏菌病又被称为牛副伤寒,是由致病性沙门氏菌感染引发的一种细菌性传染性疾病,患病牛、带菌牛是最主要的传染源,病原主要经消化道传播。不同年代的牛感染沙门氏菌后表现的症状存在一定差异性,其中对犊牛造成的危害最为严重大,多数患病牛表现为败血症、胃肠炎等症状。牛沙门氏菌病具有发病急、传播速度快、感染率高、致死率高、治愈率低的特点。发病流行后,需要养殖户采取综合性措施防控,以取得良好的防治效果。该文探讨牛沙门氏菌病诊断和防控措施。

Bovine salmonellosis,also known as bovine paratyphoid,is a bacterial infectious disease caused by a pathogenic salmonella infection.Infected cattle and infected cattle are the major source of transmission.There are some differences in the symptoms of the cattle infected with salmonella in different ages,among which the harm to the calves is the most serious,and most of the infected cattle show septicemia,gastroenteritis and other symptoms.Bovine salmonellosis is characterized by acute onset,rapid transmission,high infection rate,high mortality and low cure rate.After the epidemic,it is necessary to take comprehensive measures to prevent and control the disease so as to achieve good control results.The diagnosis and control measures of bovine salmonellosis were discussed in this paper.
