- Gut-associated microbiota in crustaceans are recognized as a key element for maintaining homeostasis and health in the animal. Since the richness of these microbial communities is strongly influenced by the local environment, especially in aquatic organisms, it is important to address to what extent environmental variations can affect these communities. In the present study, we used high-throughput 16S rRNA sequencing technology to study the composition of gut-associated microbiota of the crayfish Pacifastacus leniusculus after exposure to environmentally-relevant concentrations of an antibiotic, namely sulfamethoxazole. Also, we examined if alterations of microbiota caused by environmentally-relevant concentrations of this antibiotic affected the host susceptibility to bacterial diseases, including Vibrio species. As a result, we found high individual variability of bacterial abundance and composition in the intestinal microbiome of crayfish, in both antibiotic-exposed and antibiotic-free crayfish. However, an increase of chitinolytic bacteria including Vibrio spp. was detected in some animals exposed to the antibiotic. Moreover, when crayfish susceptibility to bacterial infections was tested, the antibiotic-exposed crayfish survived longer than the control crayfish group. This study represents the first approach for investigating the interplay between crayfish and intestinal bacteria during antibiotic-pollution scenarios. Results herein should be considered by scientists before planning experiments under laboratory conditions, especially to study environmental effects on aquatic animals' intestinal health and immune status.
