Abstract

 It was established that the structure of bacterial homeostasis in the distal intestine of pigs the correlation of obligate anaerobes and value for MAFAnM by protozoonic  invasion is 1,01: 1, nematodozic invasion – 1,09:1 and mixed infestations – 0,93:1, while in healthy animals such index was 1,59:1. Reducing the number of obligate anaerobic microorganisms in the intestinal contents of infested pigs compared with a control group of animals is by reducing the number of microorganisms genus Bifidobacterium by protozoonic infestation by 25,9 % (p<0,01), the nematodozic  – 14,8 % and for mixed infestations – 39,8 % (p <0,001), Eubacterium spp. by protozooznic  invasion to 179,6 % (p <0.001), nematodozic  – at 173,9 % (p <0,001) and mixed invasion – by 187,5 % (p<0,001), Prevotella spp. by protozooznic  invasion – by 11,9 %, nematodoznic – 8,3 %, by   mixed invasion – by 14,3 % (p <0.05) and Propionobacterium spp. respectively – 9,5, 6,0 and 13,1 % against the background of  increased number of Clostridium spr. By protozooznic invasion by 23,6 %, nematodoznic  – by 16,4 % and mixed-protozooznic and  nematodoznic  invasion – by 41,8 % (p <0,05), and population of Fusobacterium spp.by  protozooznic  by 7 times, nematodoznic – at 6,4 and mixed invasion – in 7,4 times. The most defined  changes of MAFAnM of distal intestine department  observed in pigs with mixed-protozooznic  nematodoznic  invasion, in which, in comparison with healthy animals, in 5,1 times (p <0.001) increases the number of E. coli Hly «-» gem «+» in 1,5 times (p<0,001) – Streptococcus spp., in 5.1 times (p <0,001) – Staphylococcus spp., 4,6 times (p<0,001) – Klebsiella spp., in 6.4 times ( p <0,001) – Citrobacter spp. and 2,3 times – Candida spp. against the background of decreased by 0,8 lg CFU / g of content quantity E. coli Hly «+» gem «-» and 2,3 lg CFU / g Lactobacillus spp. of content. Compared with healthy animals, in pigs by protozooznic  invasion is reduced by 40,0 %, nematodoznic– by 26,7 % and mixed-protozooznic and  nematodoznic invasion – by 50.0% stability Index of intestine micro flora.
