猪副伤寒流行病学、鉴别诊断及防控

Epidemiology,Differential Diagnosis,Prevention and Control of Swine Paratyphoid

猪副伤寒是一种细菌性传染性疾病,又被称为仔猪沙门氏菌病,它是由致病性沙门氏菌感染引起的一种以败血症、坏死性肠炎及肺炎为主要症状的传染性疾病。成年猪对致病原的抵抗能力较强,感染该种疾病后通常不会表现出明显的临床症状,呈现隐性发病经过,成为养殖场主要传染源。温度发生突变、养殖密度过大、阴雨潮湿是诱发该种疾病传播流行的最主要原因。该文分析猪副伤寒的流行病学、临床症状、鉴别诊断方法和防控措施。

Swine paratyphoid is a bacterial infectious disease disease,also known as salmonellosis in piglets.It is caused by the pathogenic salmonella and is characterized by septicemia,necrotizing enterocolitis and pneumonia,which are the main symptoms of infectious disease.Adult pigs have strong resistance to the pathogen,usually do not show obvious clinical symptoms after being infected with the disease,and become the main source of infection.The temperature mutation,the density of breeding is too large,wet and rainy is the most important reason to induce the spread of the disease.The epidemiology,clinical symptoms,differential diagnosis and control measures of porcine paratyphoid fever were analyzed.
