Myxomatosis in rabbits: symptoms, treatment, prophylaxis
- 15 Aug 08:45
One of the most dangerous diseases for rabbitsveterinarians are called myxomatosis. This is an infectious disease that occurs in acute form. The virus causing myxomatosis in rabbits shows a very high resistance, keeping the activity of dead animals for a week, and in dried skins for a year.
Given the epidemic nature of the disease, many farms conduct regular animal vaccinations, but even this preventive measure does not guarantee complete protection against the virus.
General information about the disease
The source of a dangerous virus can be several:
- all rabbits that are sick or already sick with purulent discharge from the nose and eyes;
- insects: mosquitoes, lice, fleas, ticks;
- also spreads the virus between animals through feed.
Mycosomatosis in rabbits, as a rule, manifests itself during the period of active reproduction of insects, that is, in the warm season. However, some outbreaks of the disease occur at any time of the year.
It is important: the virus is susceptible to both wild and domestic rabbits, regardless of sex, breed or age. Animals that have suffered from the disease, for a long time, are the carrier of the virus.
Clinical picture of the disease
The duration of the incubation period of myxomatosis varies from two to twenty days and depends on the health of the rabbit. The disease always occurs acutely and there are two forms.
1. Classical form of myxomatosis
Appears in the form of edema on the skin of the gelatinous consistency and small size. The mortality of rabbits in this case is 100%.
2. Nodular( nodular) form of myxomatosis
Is accompanied by the formation of tumors. The mortality rate ranges from 70% to 90%.
Symptoms of Myxomatosis Rabbits
The main symptoms of acute forms of the disease:
- skin redness;
- humps on the skin, ears and ages;
- overspread and swollen auricles;
- purulent conjunctivitis, which leads to swelling of the eyelids, as a result, eyes are tearing, and eventually begin to blunt;
- wheezing, breathing difficulties;
- high temperature( up to 41 degrees).
Symptoms of the nodal form of the disease are as follows:
- the formation of nodule size with a dove egg in the back area, on the ears and extremities.
After several weeks, tumors are transformed into necrosis cells. In case of recovery, the affected areas heal. At nodular form, the body temperature of rabbits does not increase. Duration of the disease on average 35 days.
Important: Myxomatosis, as a rule, is accompanied by secondary infections. The most commonly associated illness is pneumonia. That is why the treatment of myxomatosis involves the appointment of a course of therapy aimed at preventing secondary infections, which lead to the death of rabbits.
Possible treatment option for
The list of medications that contribute to healing. This instruction does not provide one hundred percent guarantee of recovery and is only recommended.
During treatment it is important to regularly measure body temperature. For rabbits, the norm is considered to be in the range of 38 to 40 degrees.
Important: Make sure that the eyes that are the source of the virus do not accumulate near the inner corner. Wipe your eyes with a clean, napkin soaked with a slightly warm, black tea.
- mycelotic rabbits during insects( May-June) do not leave domestic rabbits on the street;
- necessarily conduct quarantine measures for new animals;
- to prevent the appearance of animal fleas and other insects;
- if the animal is ill, immediately isolate it;
- animal cells require regular treatment with disinfectants;
- to regularly and promptly vaccinate all rabbits.
If preventive measures have not helped and the disease develops, all infected animals must be destroyed.
Despite the fact that the vaccine does not provide complete protection against the disease, the risk of myxomatosis is significantly reduced, the disease proceeds in a light, non-typical form, and the percentage of survival is increasing.
In vaccinated rabbits, the disease manifests itself in the form of minor swelling or nodules. These symptoms eventually pass by themselves. Validity of the vaccine - no more than nine months.
If the vaccine is subcutaneously administered, one dose of the vaccine and one half dose of the solvent are required. In the thigh introduce 0.5 ml of the drug.
For intradermal injections, one dose of vaccine and 0.2 dose of a solvent are required. Inject the drug into the ear area in the amount of 0.2 ml of
. After vaccination, the immunity is formed within nine days.
Important: Vaccination is not susceptible to rabbits up to six weeks old. It is possible to inoculate only healthy animals, since infected people are no longer able to acquire immunity. After administration of the drug, quarantine is required for two weeks. In rare cases, the vaccine does not work on a rabbit.
In conclusion, it should be noted that myxomatosis develops so acutely and quickly that therapy does not produce an adequate result. That is why many veterinarians find it inappropriate to treat rabbits from this disease.
