ABSTRACT
Freshwater snail is an important biological group in aquatic ecosystem and an intermediate host of many parasites. Intestinal flora plays an important role in animal energy metabolism and resistance to pathogens. We analyzed the intestinal microbiota diversity of Radix auricularia (RA) and Planorbella trivolvis (PL) by 16S rRNA high-throughput sequencing. At the phylum level, RA had 23 phyla, including Proteobacteria (33.63%), Cyanobacteria (15.33%), Chloroflexi (13.95%), and Actinomycetes (12.99%). PL had 13 phyla, including Proteobacteria (54.88%), Bacteroidetes (28.49%), and Actinomycetes (7.65%). At the genus level, there were 445 genera in RA, including Pleurocapsa, Thiodictyon, Leptotrichia, and Nocardioides. There were 238 genera in PL, including Cloacibacterium, OM60NOR5_clade, Pseudomonas, and Rhodobacter. Ninety-three genera were the common core flora of the two snail species (all the samples were present), and 27 genera had an abundance greater than 0.5%. The structure of intestinal microbiota was significantly different between the two groups (P=0.027). We performed the functional prediction of intestinal microbiota using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt), and the results show that the KEGG functional composition of the intestinal flora of the two snails was similar, and the abundance of the amino acid metabolism, carbohydrate metabolism and membrane transport were large. In summary, the intestinal microbiota of the two snails was high in diversity and significantly different, but there were a large number of common core flora.
