[PDF] Gut Microbiome Analysis of Snails: A Biotechnological Approach | Semantic Scholar (2024)

Putative cellulose-degrading bacteria are enriched in the gut of P. canaliculata snails and the composition of the microbiota was diverse among the different gut sections.

The snail harboured microbiota that was distinct for its environment, and the microbiota of infected snails was found to differ significantly from that of uninfected snails, paving the way to future studies on the functional roles of bacteria in host-parasite relationships.

The gut microbiota of B. glabrata helped in the digestion of complex polysaccharide such as starch, hemicellulose, and chitin for energy supply, and protected the snail from food poisoning and nitrate toxicity, and was enriched in the gut of snails fed with high-digestibility protein and high polySaccharide diet (HPHP).

The obtained data demonstrated that the snail mucus creates a unique environment for the development of the microbial community that differs from other parts of the animal and which resulted from the combined contribution of the microbiomes derived from the soil, plants, and the snails.

Gut microbial ecology and its interplay with the host thus contribute to the nutritional and metabolic demands of A. marisindica and the findings advance the understanding of how deep-sea chemosymbiotic animals use available resources through contributions from gut microbiota.

Comparisons of gut microbiomes in O. strigosa adult, fetal, and starved samples provide evidence that the host internal environments influence bacterial community compositions, and that bacteria may be transmitted vertically from parent to offspring.

Biodiversity of microbial communities on some species of Gastropoda is evaluated, thereby predicting their interaction and it is possible to predict the nutritional relationship between microorganisms and species of gastropoda.

Along with providing a review of the known molluscan host/microbe mutualistic symbioses, this work outlines common methodologies in the study of these relationships and point out areas of further exploration for mollUScan microbiome studies.

Assessment of the complexity of bacterial communities occurring in the digestive tracts of field-collected snails by using culture-independent molecular analysis shows that this is a complex holobiont system containing diverse, abundant and active microbial communities.

The results document the presence of highly diverse gut bacterial communities in three snail species and indicate the need for additional study to determine the roles that gut microbes play in the physiology and immunology of planorbid snails.

Evaluated the possible differences in the intestinal microbiota between snails (Helix aspersa) of different weights to establish the relationship between both and showed no statistically significant differences between the two study groups in bacterial counts.

Investigating the dietary habits of Pectinodonta sp.

A metagenomic analysis of the bacterial community resident in the hindgut paunch of a wood-feeding ‘higher’ Nasutitermes species shows the presence of a large, diverse set of bacterial genes for cellulose and xylan hydrolysis, the first system-wide gene analysis of a microbial community specialized towards plant lignocellulose degradation.

The intestinal bacteria is discussed in the context of developing understanding of symbiotic relationships, of multitrophic interactions between insects and plant or animal host, and in developing new strategies for controlling insect pests.

This pilot study establishes the first in-depth inventory of the gut microbiota of a model organism from the mostly phytophagous Lepidoptera, and shows that Pyro-SIP can rapidly gain insight into the Gut microbiota's metabolic activity with high resolution and high precision.

In Cornu aspersum reproductive strategy depended on seasonal time constraints and investment in reproduction was influenced by the energy available in the environment, and Helix pomatia preserved a rich bacterial community in the gut probably with ice nucleating bacteria and accumulated cryprotectants to enhance cold hardiness during hibernation.

It is concluded that snails are not 'picky' eaters at the microbial level, but graze the surface of whatever plant they are on, which enables effective management when conservation requires captive breeding or field relocation.

Prevalence and taxonomic position of snails are furnished, and biochemical activity of 18 unidentified cultures isolated from Snail gut help to understand compexisity of bacterial community in snail gut and their role in digestion of cellulose, pectin, lignin, containing plant constituents.
