ABSTRACT: In recent decades
snail consumption has been increasing throughout Europe. The Heliciculture
meets this need and gets snail farms, in order to get consistent production in
the shortest possible time. The research provided, has a main objective to
establish the microbiota of Helix aspersa Müller, both from healthy animals, and individuals with gastrointestinal
processes. The samples selected for the study were feces obtained from snails
collected in both breeding farms as field snails. In the case, farm animals
were selected apparently form healthy individuals and others were with signs of
gastrointestinal process study. Aliquots of each sample were plated on a range
of culture media and incubated under different conditions of temperature and
respiration. From the results we can note that the healthy snails (farmed or
free-living) have been isolated and identified mostly, as strains belonging to
the genera Pediococcus, Lactobacillus and Lactococcus and five strains of yeasts of the genera Candida and Cryptococcus. Individuals suffering from gastrointestinal
disturbances processes have been isolated in high proportion species of Klebsiella, Pantoea, Citrobacter and Enterobacter. The results obtained indicate
that the snails with health problems reduce the presence of strains of Lactobacillus and Lactococcus in favor of increasing and/or establishing colonization
by strains of Enterobacteriaceae.
