The distemper is dog's one kind of altitude contacting, the lethal infectious disease which causes by the distemper virus.Early double-phase body warming up, symptom similar cold, afterwards take bronchitis, catarrh pneumonia, gastroenteritis as a characteristic.Sickness later period obviously has the nerve symptom to appear like the convulsion, to twitch.The partial case of illness may appear the nose department and the angle pad keratinization (hard foot pad gets sick) highly.
[Epidemiology] this gets sick may occur throughout the year, but spring sends by the winter.This sickness has certain periodicity, every three years a high prevalence.The disparity in age, the sex and the variety dog may infect, but by underage young dog easiest feeling.The purebred dog, the police dog plants the dog susceptivity the earth to be higher than, moreover the condition responds heavily, the mortality rate is also high.This gets sick the most important origin of infection is the nose, the eye secretion and the urine.Once some people after reported the infection dog acute communicable disease virus's dog 60-90 day, in the urine still had the virus to discharge, therefore said the urine was the very dangerous origin of infection, mainly disseminated the way is sickness dog and the healthy dog direct contact, also might infect through the air priming after the respiratory tract.One has the dog acute communicable disease but with the room dog to discover, regardless of how strict protective measure takes, all cannot avoid living together the one room dog infection.
[Symptom] the distemper incubation period is 3-9 day.Symptom many and varied, with the toxicity strong and the weak, the environmental condition, the age and the immunity condition concerns.The distemper starts the symptom is a rise of bodily temperature, continues for 1-3 day.Then the retrogression, resembles cold healing very much the characteristic.But after several days the body temperature elevates once more, the duration does not decide.Obviously has bursts into tears, the tunica conjunctiva oculi blushes, the eye secretion turns mucopurulent by the liquidity.The nose boundary becomes dry, has the nose liquid flow to leave, starts is the size nose fluid, latter turns the purulent nose fluid.Gets sick initially has coughs without expectorating, latter transfers coughs wet, breath difficulty.Vomitive, diarrhea, intestines set of repeat, finally by serious dehydration and feeble death.
The nerve symptom dog acute communicable disease, mostly about 10 days appears in the above symptom.On clinical by the foot pad keratinization, nose department keratinization case of illness causes the nervous symptom to send.Because the distemper virus violation central nervous system spot is different, the symptom has a difference.The viral damage in the brain, displays for epilepsy, turns circle, stands the attitude exceptionally, the gait not steady, altogether aids the detuning, chews the muscle and the four limbs appears the paroxysmal to twitch and so on other nerve symptom, this kind of nervous dog acute communicable disease prognosis many for is not good.
The distemper virus may cause the partial dog eye damage, on clinical take the conjunctivitis, the keratitis as the characteristic, the keratitis mostly is in is taken bad about latter 15 day to see, the cornea bleaches, heavy may appear the keratohelcosis, the perforation, loses one's sight.
This sickness is very high in the young dog mortality rate, the mortality rate may reach 80~90%.And may continue sends pneumonia, enteritis, symptoms and so on intestines set of repeat.
On once clinical has the characteristic value distemper symptom, the prognosis is very bad.Specially has not made the immunity dog.Although on clinical carries on the just right for the illness treatment, but is very difficult to the condition development to control, mostly by nerve symptom and failure death.The part restores the dog all may leave behind the varying degree generally the sequela.
[Prevention and control]
(1) this gets sick the precautionary measure carries on the immunity vaccination dog acute communicable disease vaccine regularly.The immunization schedule is: The head exempts time on 50th the age to carry on; Two exempts time on 80th the age to carry on; Three exempts time on 110th the age to carry on.After three immunities, later every year the immunity one time, at present in the market sells six association seedlings, five association seedlings, three association seedlings might carry on the immunity according to above procedure.
Once (2) has the distemper, in order to prevent the epidemic situation spread, will have rapid to get sick the dog strict isolation, sickness shed and the environment with the fire alkali, the sodium hypochlorite, comes Soviet and so on to disinfect thoroughly.Strict prohibition sickness dog and healthy dog contact.To not yet is taken bad has the infection possible hypothesis healthy dog and the epidemic situation threat dog, should use the distemper to exempt the blood serum immediately to carry on the passive immunity or to make the urgent immunization high with the young child measles vaccine, after treats the epidemic situation stably, then injects the distemper vaccine.
[Treatment] after has the clinical symptom the available large dose distemper exempts the blood serum to carry on the injection high, may control the development which the book gets sick.Gives off heat at first in the distemper the period gives the large dose to exempt the blood serum high, may make organism to strengthen the enough immune body, prevented has the clinical symptom, achieves the treatment goal.Is obvious regarding the distemper clinical symptom, has the nerve symptom mid and late part sickness, even if injects the distemper to exempt the blood serum mostly very to be also difficult high to cure.
Just right for the illness treatment: Makes up the sugar, the fluid infusion, brings down a fever, prevented continues sends the infection, methods and so on enhancement raising management, has certain treatment function to this sickness. |
