HISTOPATHOLOGICAL CHANGES IN CHICKENS DIED AT THE ASSOCIATIVE CURRENT OF MALLOPHAGOSIS AND DERMANISSIOSIS
The article is devoted to morphological changes in the tissues of chickens died during the associative course of mallophagosis and dermanissiosis. These diseases have become widespread in the Stavropol region. These ectoparasites can be carriers of a number of diseases dangerous to birds, such as salmonellosis, erysipelas, smallpox-diphtheria, pasteurellosis, borreliosis, etc. The presented ectoparasitoses cause significant damage to poultry farming in the region. To date, there are publications on the pathological changes in chickens that died during the associative course of these ectoparasitoses, but information on morphological changes is extremely scarce. The material for the work was the chickens died from the associative course of these ectoparasitoses in private farms of Shpakovsky, Grachevsky and Izobilnensky districts of the Stavropol region. 30 pathological autopsy autopsies of birds were carried out, from 5 of which the skin and internal organs were selected for histological examination, which was carried out according to the standard method. During a histological examination in chickens that died during the associative course of mallophagosis and dermanissiosis, the following changes were established: vacuolar liver dystrophy, parenchymal myocarditis, moderate spleen hypertrophy, chronic desquamative salpingitis, chronic dermatitis with focal hyperkeratosis, subacute desquamative enteritis, chronic interstitial orchitis
