Content of microorganisms larvae Strongyloides westeri
AbstractThe associations of parasites in animals are diverse both in taxonomic respect (helminthes, protozoa, viruses, bacteria) and due to pathology caused by them. Strongyloides are often associated with parasitocenosis of animals, forming close symbiotic links with pathogens of infections. Penetrating into the body percutaneous or alimentary, larvae of helminthes inoculate bacteria and viruses, thereby complicating the course of diseases. In order to study the probability of persistence of microorganisms in the body of Strongyloides westeri larvae, larva homogenate was sown to nutrient media. Isolated microorganisms differed in terms of appearance, pigmentation and cultural properties, forming on colonies of S- and R-forms on dense nutrient media. In the broth, turbidity was detected, the formation of a precipitate and a film on its surface. Bacteriological studies of Strongyloides westeri homogenate larvae identified 7 cultures of microorganisms that were identified as representatives of the families: Enterobacteriaceae (genera Enterobacter, Escherichia, Klebsiella, Proteus) Micrococcaeae (genus Streptococcus, Staphylococcus) Bacillaceae (genus Bacillus). In the homogenate samples of larvae of all experimental animals (100%), bacteria of genera were found: Enterobacter, Escherichia, Klebsiella, Bacillus, Staphylococcus, 60% identified bacteria of the genus Proteus, 20% of the genus Streptococcus. The conducted studies established the parasitocenotic connections of Stongyloides westeri larvae and the microorganisms of seven different genera belonging to three families. The results of the studies confirm the ability of nematode larvae of the species Strongyloides westeri to be bacterial reservoirs. Helminthes is one of the probable ways of getting microorganisms into the body of a receptive host.
