“…to outcompete other taxa on reptilian oral mucosa. The genus Halioglobus is typically found in seawater, marine sediments, and has been associated with dino agellate blooms and starving green-lipped mussels [41,42]. We have previously reported Halioglobus in oral samples of loggerhead sea turtles [24].…”

Background The research on microbial communities of marine megafauna species represents a valuable source of knowledge that could be used for species conservation programs. Loggerhead sea turtles are marine flagship species with a currently thriving population in the Mediterranean Sea due to strong conservation efforts. In our study we aimed to further understand their biology in relation to their associated microorganisms. We investigated bacterial and fungal community structure of cloacal, oral swabs and carapace biofilm samples obtained from 18 juvenile, subadult and adult turtles as well as 8 respective enclosures, during a period of 3 years, by amplicon sequencing of 16S rRNA gene and ITS2 region of nuclear ribosomal gene. Results Our results reveal a trend of decreasing diversity of distal gut bacterial communities with the age of turtles. Notably, Tenacibaculum genus shows higher relative abundance in juveniles than in adults. Differential abundance of genera like Tenacibaculum, Moraxellaceae, Cardiobacteriaceae, and Campylobacter was observed in both cloacal and oral samples in addition to having distinct microbial compositions such as Halioglobus genera in oral samples. Fungal communities in loggerheads' cloaca were diverse and varied significantly among individuals, differing from those of tank water. However, we could not identify discernible patterns related to age, sex, or clinical status due to study limitations. Conclusion This study provides a comprehensive view of the loggerhead sea turtle bacterial microbiota and marks the first report of distal gut fungal communities studied via amplicon sequencing. Our findings expand the known microbial diversity repertoire of loggerheads, highlighting interesting taxa specific to individual body sites. This contributes to establishing a baseline understanding of the loggerhead bacterial and fungal microbiome.

Research on microbial communities associated with wild animals provides a valuable reservoir of knowledge that could be used for enhancing their rehabilitation and conservation. The loggerhead sea turtle (Caretta caretta) is a globally distributed species with its Mediterranean population categorized as least concern according to the IUCN Red List of Threatened Species as a result of robust conservation efforts. In our study, we aimed to further understand their biology in relation to their associated microorganisms. We investigated epi- and endozoic bacterial and endozoic fungal communities of cloaca, oral mucosa, carapace biofilm. Samples obtained from 18 juvenile, subadult, and adult turtles as well as 8 respective enclosures, over a 3-year period, were analysed by amplicon sequencing of 16S rRNA gene and ITS2 region of nuclear ribosomal gene. Our results reveal a trend of decreasing diversity of distal gut bacterial communities with the age of turtles. Notably, Tenacibaculum species show higher relative abundance in juveniles than in adults. Differential abundances of taxa identified as Tenacibaculum, Moraxellaceae, Cardiobacteriaceae, and Campylobacter were observed in both cloacal and oral samples in addition to having distinct microbial compositions with Halioglobus taxa present only in oral samples. Fungal communities in loggerheads’ cloaca were diverse and varied significantly among individuals, differing from those of tank water. Our findings expand the known microbial diversity repertoire of loggerhead turtles, highlighting interesting taxa specific to individual body sites. This study provides a comprehensive view of the loggerhead sea turtle bacterial microbiota and marks the first report of distal gut fungal communities that contributes to establishing a baseline understanding of loggerhead sea turtle holobiont.
