Prevention and treatment of rabies in nutria

The main results are as follows: 1) in the forebody stage, the mice were short-term depressed and slow in movement, and the symptoms in this period were not easy to detect.

2) during the exciting period, the mice showed excitement, aggressive behavior, attacking people and other animals, biting, scratching and tearing all the objects encountered. The affected mice can damage their tongue, teeth, gums and break their lower teeth. The infected rats refuse to eat, do not drink water, and often swallow all kinds of objects put into the cage. Repeated episodes during the raging period, during which the rats moaned, salivated and diarrhea.

3) during the paralysis period, the paralysis process was enhanced, showing hindquarters shaking and hindlimb paralysis. Hypothermia. The sick rats could not get up, lay down unconsciously, and died of spasms and convulsions.

(2) the gastrointestinal mucosa was congested or bleeding, the liver was dark red, flabby, the spleen was slightly larger, and there were also cases of 2-3 times larger than the normal spleen. Anemia was found in the kidney, and the boundary between cortex and medulla disappeared. There are some cases of pulmonary hemorrhage. Congestion occurs in the brain because blood vessels are highly filled and dilated by the blood. There is an increase of fluid in the ventricle and punctate hemorrhage is often found in the brain tissue.

4) the measure to prevent rabies in nutria farms is to resolutely prevent foreign dogs from entering the human nutria breeding area, and breeders should also be vaccinated against rabies. If rabies rats are found in the farm, the blockade should be resolutely carried out, and the epidemic situation should be reported to the competent department at a higher level in time. Resolutely put an end to the sick rats running out of the field, burning or burying the bodies of sick or dead mice diagnosed as rabies; check the individuals who did not suffer from the disease one by one, and find the sick rats in time. All healthy mice were injected with rabies hyperimmune serum and 7-iO days later were injected with rabies vaccine. From the last case of rabies death, the blockade was lifted after 2 months.
