Gut microflora plays an essential role in host physiological activity, and it contributes significantly to both the health and diseased states of animals. However, thus far, no study has focused on the correlation between diseases and intestinal bacterial communities in crocodilians. Here, we first compared the composition and function of gut microbial communities in captive juvenile <jats:italic>C.\u00a0siamensis<\/jats:italic> suffering from anorexia and healthy crocodile controls using deep amplicon sequencing. The gut microbial diversity of anorexic crocodiles was much lower than the healthy individuals. Obvious changes in gut microbial composition were observed between sick and healthy crocodiles, except for <jats:italic>Cetobacterium\u00a0somerae<\/jats:italic> of phylum Fusobacteria. In particular, the abundance of <jats:italic>Bacteroides luti<\/jats:italic>, <jats:italic>Clostridium disporicum<\/jats:italic>, <jats:italic>Plesiomonas shigelloides<\/jats:italic>, and <jats:italic>Odoribacter<\/jats:italic> sp. in the gut flora of healthy crocodiles was distinctly higher than the diseased group. Conversely, the species <jats:italic>Edwardsiella tarda<\/jats:italic> was overrepresented in the gut of anorexic crocodiles compared to the healthy group. Furthermore, in anorexic crocodiles, the predicted microbial functions that were related to amino acid metabolism, biosynthesis of other secondary metabolites, nucleotide metabolism, replication and repair, and translation were significantly reduced, while signal transduction was significantly enriched. These findings of the present study provide a reference to enrich the field of gut microorganism studies in crocodilians and suggest that alterations in the composition and function of gut bacteria in <jats:italic>C.\u00a0siamensis<\/jats:italic> juveniles may be associated with anorexia in crocodiles.<\/jats:p>","DOI":"10.1002\/mbo3.929","type":"journal-article","created":{"date-parts":[[2019,9,4]],"date-time":"2019-09-04T08:31:00Z","timestamp":1567585860000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Comparative
