In the conditions of the Republic of Belarus there was studied the propagation of associative parasitic diseases of swine of different age-specific groups, as well as their influence on composition of microbial flora of large intestinal tract. As a result of realized studies in different age-sex groups of pigs there were revealed some monoinfections (A. suum; T. suis; Eimeria sp.) and associations (A. sum; T. suis; Eimeria sp.; Oesophagostomum dendatum; B. coli) in different ratio (depending on sex and age-specific groups). There were revealed a certain peculiar features in changing of microbiocenosis of large intestinal tract of swine under the influence of parasitic agents (namely, in cases of parasitic diseases caused by A. suum; T. suis; Eimeria sp.; O. dendatum; B. coli both in the form of mono infestations and in associations). These features were expressed by lowering of standard flora quantity (bifid bacterium and lactic acid bacillus) with a simultaneous increasing of the content of opportunistic coliform bacillus, aerobic bacteria, bacilli, and micromycetes.
