Dystrophic Changes in Echinococcus Cysts Complicated by Fungi of Aspergillus and Paecilomyces Genus

Relevance of the Research Problem: To establish that fungi found in echinococcus are representatives of Paecilomyces genus. Materials and methods: The study of blood in animals on the content of Paecilomyces and micrometric study of hydative bubbles, presence of spherules of fungi and microflora hydative fluid. Results. It all tissues of hydatid bilayer capsule a marked necrotic reaction that in the three cases was the area of fresh necrosis was noted. Occurrence of eosinophilic reactions caused by parasite morphological modifications has not been established: it was found in one-third of capsules of parasites of all modifications. Only in infertile echinococcus a capsule contained considerably more of cellular elements. In bacteriological examination most diverse microflora was found in the fluid of dystrophically changed hydative cysts. Unlike viable cysts in half cases they contained monoculture and in half cases association of various microbes containing fungi. Conclusion: Contrary to the majority of researchers we established that echinococcus fluid contains microbial flora in 74% of causes including Aspergillus and Paecilomyces genus as well
