Borreliosis or Lyme disease in dogs is a disease that is borne by ixodids and other mites.
They infect the dog during walks through the forest in a temperate climatic zone, where they can pick up an infected tick. Most often, dogs are attacked by mites during the spring-autumn period.
Once Lyme disease was found only in the US and Canada. However, in recent years it began to spread actively in the countries of Europe and Russia. And the area of borreliosis coincides with the area of tick-borne encephalitis, this increases the possibility of infection with both infections simultaneously.
This is a deadly disease, which is transmitted even in utero, which leads to the death of the fetus.
Symptoms of borelliosis in dogs
The course of this disease is characterized by the predominance of an asymptomatic latent form. As a rule, only 5-20% of infected dogs show clinical manifestations. For a long time, even for years Borrelia can persist in the animal's organism, causing a chronic course of the disease.
The main symptoms in the recurrence of an acute disease:
- Fever with high fever,
- Change gait because of muscle pain,
- Soreness and swelling of the joints,
- Migratory arthritis ,
- Swelling of the lymph nodes.
At first, the nodes that are closest to the site of the tick bite swell. The most characteristic sign is lameness and arthritis. The disease usually develops with attacks. Moreover, attacks of arthritis may return after treatment months later, or even years. One or two months after the appearance of the first symptoms, the lesion spreads to the organs, disrupting their functions.
At this stage of Lyme disease, muscle tone decreases, muscle pain progresses, neurologic disorders and a decrease in cardiac activity appear.
Treatment of Lyme disease
If such symptoms occur, it is necessary to urgently contact the veterinarian and undergo the necessary examinations: PCR, light or electron microscopy, indirect immunofluorescence. The disease in most cases is treated with antibiotic therapy, but rather long - up to a month.
Effective are cephalosporins, amoxicillin, preparations of the penicillin series, tetracyclines. Pathogenetic therapy is also necessary. However, there is evidence that antibiotic treatment for labradors and retrievers is ineffective.
Against the background of the use of antibacterial drugs, there is often a marked exacerbation of the symptoms of the disease. This is due to the release of endotoxins into the blood and the mass death of spirochetes.
