Results of the investigation of influence of neoascarosis monoinvasion on state of intestinal canal microflora of calves as well as influence of mixed invasions (neoascarosis + eimeriosis, neoascarosis + strongyloidosis) on state of intestinal canal microflora were presented. Research results showed that cattle neoascarosis both in small and large intestines caused the dramatic disbalance in microflora quality and quantity and its intensity depended on the intensity of infestation and presence of the concomitant ones. The quality and quantity disbalance of intestinal canal microflora revealed in lowering of nonpathogenic microflora (bifidobacterium, lactobacillus and intestinal bacteria) and in increasing of the facultative microbes (proteus and clostridia). Also, there were stated high quantities of streptococcus and staphylococcus organisms and increased number of fungi and yeasts. It was stated that mixed invasions caused more intensive disorder of intestinal canal microflora in comparison with mono - infestations that could happen due to the biological peculiar properties of the parasites as well as due to the severe course of the associative invasions. Registered changes of the microflora composition of calves with neoascarosis and associative parasitic diseases were typical for the dysbacteriosis. Research result proved the necessity of the analysis of quantity and quality composition of intestinal canal microflora for the quality therapy of cattle parasitic diseases
