4 laboratory inspection

4.1 No bacteria were found in the smears of heart, blood, liver and spleen of dead pigs, Gram staining and Wright's staining.

4.2 the mucus and bloody feces of acute diseased pigs were taken and the same amount of normal saline was added to make suspension. When the suspension was examined by dark field microscope, 3-5 spirochetes with consistent shape, sharp ends and serpentine activity could be seen in multiple visual fields.

5 Prevention and treatment

5.1 the whole herd pigs were fed with dysentery net (3-methyl-2-acetyl-quinoline-1, 4-dioxides) and 50g dysentery per 10kg feed for 3 days as a course of treatment.

5.2 the infected pigs were intramuscularly injected with 0.5% dysentery according to the body weight of 5mg/kg, twice a day for 3 days; the feed was added with compound vitamin B powder, the weak were intramuscularly injected with vitamin K3 and vitamin B12, and those with severe dysentery were given intraperitoneal fluid replacement with grape grain normal saline, and intramuscular injection of epinephrine for symptomatic treatment.

5.3 isolate sick pigs and strengthen feeding and management, pay attention to cold protection, good hygiene, and strictly implement the single feeding system of all in and all out, so as to prevent the epidemic from spreading to breeding and nursing pig areas.

5.4 formulate a rodent control plan and concentrate on harmless treatment of feces. After using the above measures, the disease was quickly controlled, and on the 3rd day after treatment, 67 seriously sick pigs gradually returned to normal except 2 died.

6 summary and experience

6.1 according to the incidence, clinical symptoms, pathological changes of autopsy, laboratory examination and treatment observation, it was diagnosed as porcine dysentery caused by Treponema suis. / p >

6.2 the outbreak of dysentery in growing and finishing pigs in this pig farm is mainly caused by the usual work focusing on breeding pigs and breast-feeding pigs, neglecting the management of growing and finishing pigs with bacteria, coupled with sudden climate change, cold protection and poor feeding and management.

6.3 for diseased pig farms, the control and purification measures of swine dysentery should be formulated immediately, with emphasis on strengthening drug prevention, feeding management and rodent control in order to achieve obvious results.
