广西牛片形吸虫病流行病学调查分析
|
摘要
为了解广西牛片形吸虫病的流行情况,在广西8个地级市不同规模牛场及散养户共采集了1 571份牛粪,采用水洗沉淀法进行检测,同时屠宰时随机抽查50头牛,观察组织及病理变化。调查结果表明,广西牛片形吸虫感染较为严重,平均感染率达69. 3%(1 089/1 571),其中南宁71. 9%(41/57)、柳州46. 3%(139/300)、梧州72. 3%(88/122)、北海37. 5%(6/16)、崇左87. 8%(652/742)、河池69. 1%(65/94)、百色39. 6%(87/220)和贵港55%(11/20),各地感染情况均有不同。牛感染片形吸虫主要病变器官为肝脏、胆囊、淋巴结,而胆囊是片形吸虫病寄生的主要地方。本调查为指导广西防治牛片形吸虫病,促进肉牛产业发展提供参考依据。
To study the prevalence of bovine Fasciola spp. in Guangxi province,a total of 1571 portions of cattle dung from ranches of different sizes and individual farms of eight prefecture-level cities in Guangxi were collected for a detection by water-washing natural sedimentation methods. Meanwhile,50 cattle were randomly selected during the butchering for observation of pathological changes. Results showed that bovine fasciola infection in Guangxi was serious,with an average infection rate of 69. 3%(1089/1571),Nanning had a rate of 71. 9%(41/57),Liuzhou had arate of 46. 3%(139/300),Wuzhou had arate of 72. 3%(88/122),Beihai had arate of 37. 5%(6/16),Chongzuo had arate of 87. 8%(652/742),Hechi had arate of 69. 1%(65/94),Baise had arate of 39. 6%(87/220),and Guigang had arate of 55%(11/20). Different places displayed different degree in infection. When cattle caught fasciolasis,organ lesions mainly occured in liver,gallbladder and lymph nodes. The gallbladder was the major parasitic site of fasciola disease. This survey provides a basis both for the prevention and control of the fasciola disease and for the promotion of beef cattle industry in Guangxi.
