Etiology

Pathogens both forms, ie acute and chronic viral paralysis, have in common with each other serological relationship, with visible signs of the disease appear quite similar.

Often the disease manifests itself in the spring and summer, but can occur at any time. After wintering possible cases of paralysis due to too warm winter.

Summer heat helps to spread the disease and overheating hives, particularly after prolonged cold weather or rain.

At a temperature of up to 30 ° C usually observed development of acute paralysis, and in its rise to 35 Chronic ° C. The cause of the outbreak of infection may become insufficient supply of protein feed in early spring, ie cerago.

Тоді бджоли починають використовувати “внутрішній” білок, which leads to a weakening of the body and increases the probability of hitting any insect infections.

In temperate zones may occur hidden (latent) infection, occurring without any visible signs.

Viral paralysis in bees feed is transmitted by contact, from patients to more fully healthy bees, through contaminated Slynn. Frequent, when both pathogen present in both insects.

Some individuals may not aching, and themselves be infected with HIV. Wandering drones and bees promotes contagion across the apiary, as permutation contaminated feed honeycomb beekeeper from one hive to another. Vector infection and is considered the varroa mite.

Signs of paralysis

Acute form of the disease tend young bee specimens. From the moment of infection to visible clinical manifestations of the disease is 4 to 15 days.

Visible signs look like:

1. bee disease affected not able to fly;

Immunity to viral paralysis of bees there, so there may be signs of relapse during the season.

All these symptoms are not specific, that refer only to this disease.

The final diagnosis is possible only after laboratory tests, held mandatory in suspected paralysis.
