The article refers to the associative infection of birds with invasive and infectious diseases in the poultry farm of the Siyazan region. In order to determine the infection with Eimeria's oocytes and opportunistic microbes of domestic chickens, pathological materials from 35- and 55-day-old chicks of domestic chickens of a silver breed were used. As a result of the study, the following causative agents were identified in the carcasses of 35-day-old birds: Escherichia coli in 11 birds (17.0%), Salmonella enteritidis in 28 birds (43.0%), Staphylococcus pyogenes aureus in 4 birds (6.1 %). ), Streptococcus faecalis in 3 birds (4.6%), and out of invasive diseases the following causative agents of eimeriosis were identified: Eimeria acervulina in 5 birds (7.7%), Eimeria tenella in 8 birds (12.3%), E .mitis in 6 birds. (9.2%), E. maxima in 5 birds (7.7%). When examining the carcasses of 55-day-old birds the causative agents of infectious diseases: Escherichia coli in 10 birds (16.6%), Salmonella enteritidis in 20 birds (33.3%), Staphylococcus pyogenes aureus in 3 birds (5.0%), Streptococcus faecalis in 6 birds (10.0%), and out of invasive diseases the following causative ahents of eimeriosis: Eimeria acervulina in 4 birds (6.6%), E. tenella in 7 birds (11.6%), E. mitis in 5 birds (8.3%) and E. maxima in 3 birds (5.0%) were studied.
