Abstract: Microbiological investigations for a carrier of pathogenic microorganisms were performed in internal organs of lambs and pigs spontaneously infected with Cysticercus tenuicollis, the larval form of Taenia hydatigena (Pallas, 1766). Studies were conducted in 2010 and first half of 2011. From the livers of the studied lambs were isolated Enterobacter agglomerans, Citrobacter diversus, Klebsiella pneumoniae and Dichelobacter nodosus, and of the pigs - Proteus mirabilis, Pseudomonas fluorescens, Bacillus sp. and Clostridium sp. From the livers of both species were isolated Pseudomonas cepacia, Campylobacter coli, Enterococcus faecalis, Staphylococcus haemolyticus, Listeria innocua and Candida albicans. Lowest number of species was isolated from the lungs of the tested animals - E. faecalis in the lambs and Streptococcus pneumoniae in the pigs. Most bacterial species were found in muscles of lamb: Escherichia coli, Citrobacter freundii, Campylobacter coli, Staphylococcus sciuri, E. faecalis and Bacillus sp. The data show that the parasites make prerequisites for penetration and growth of pathogenic microorganisms in internal organs of affected animals. Results from the studies of extracts of infested and healthy livers of lambs for antibacterial effect strongly suggest that Cysticercus tenuicollis has inhibitory effects on microorganisms isolated from infested organs. Even more pronounced was that effect on bacteria that were not in contact with this parasite. Microorganisms growing in organs with invasion of Cysticercus tenuicollis, to some extent develop resistance and less influenced by inhibiting factors emanating from it.
