THE INFLUENCE OF KNEMIDOCOPTOSIS AGENTS ON GENERAL STATE OF PET BIRDS

Introduction. Knemidocopes spend most of their lives in the epidermal layer of the skin of pet birds. Sliding, ticks with their bristles and suckers on their tarsal segments, irritate the skin receptors and cause itching in birds. Mechanical and irritant action of ticks intense sensitization and allergic reaction in the bird organism.

The goal of the work was to study the pathogenic effect of knemidocopes on the parrots and canaries organisms.

Materials and methods. The clinical studies of pet birds (behavioral monitoring, feed and water intake; determination of body temperature, pulse rate, respiration) were performed according to conventional methods. In sick pet birds we considered: localization and area of lesion, changes in the skin, the presence of itching, as well as data on the time of occurrence and nature of the invasion.

Results of research and discussion. It was established that knemidocoptosis in decorative birds clinically occurred in two forms: acute and chronic. The chronic course of knemidocoptosis was diagnosed more often with an incidence of invasion of 92.4%, and an acute course – 7.6%. According to the results of studies, the course of knemidocoptosis in pet birds was conditionally divided into three main stages. The results of morphological studies of the blood of invasive birds indicated significant changes of their organism and may indicate activation of the immune system.

Conclusions and prospects for further research. In parrots and canaries the most common chronic course of the disease characterized by damage of the beak, head, neck, inner surface of the wings and legs. The period from the beginning of infection to the first clinical signs depends on the state of the immune system of the birds. Further studies will focus on the continued study of the effects of knemidocopes mites on the body of chickens, pheasants, peacocks and guinea fowls, as well as a more detailed study of the immune system of birds in this pathology.

Keywords: knemidocoptosis, skin, course of the disease, blood.
