“…In the present study, the macrolide ARG macB was most abundant in the farm (6.9%) group, followed by the wild (6.7%) and released (6.1%) groups. Our results align with previous studies showing that macB is more abundant in green sea turtles compared to hawksbill communities [ 41 ]. Moreover, Seribelli et al (2021) also detected macB among the bacterial strains isolated from humans, food, and swine [ 88 ].…”

“…ARGs are environmental pollutants that pose potential risks to human and animal health due to the release of resistant pathogens, and they vary around the globe [ 86 ]. Many studies have stated that ARGs are found in various environmental compartments, such as fecal contents, soil, river water, and drinking water [ 41 ]. The present study found the most common and leading ARGs to be macrolides, aminocoumarin, and tetracycline resistance genes in each fecal content group.…”

“…Moreover, tetracycline antibiotics are also found in both terrestrial and aquatic environments and exert pressure on bacteria; as a result, ARGs are found in the environment [ 89 ]. Chen et al (2022) stated that there is a great richness of tetracycline resistance genes in hawksbills and green sea turtles [ 41 ]. In the current study, tetracycline ARGs are also abundant in the wild group, which might be due to the discharge of wastewater from farms or via their prey, such as small wild animals with diverse habitat ranges.…”

“…To date, various metagenomic analyses of intestinal microbiota have been performed with vertebrates, such as humans [ 34 ], cattle [ 35 ], red swamp fish ( Procambarus clarki ) [ 36 ], amphibious mudskippers ( Periophthalmus chrysospilos ) [ 37 ], chickens [ 38 ], pigs [ 39 ], amur tigers [ 40 ], and in between hawksbills ( Eretmochelys imbricata ) and green sea turtles ( Chelonia mydas ) [ 41 ]. In addition, a chicken multi-kingdom microbiome catalog has been studied, including bacterial, archaeal, and viral genomes, and this has provided functional insights into the chicken gut microbiota, paving the way for microbial interventions to improve chicken gut health and productivity [ 42 ].…”

The intestine of living organisms harbors different microbiota associated with the biological functioning and health of the host and influences the process of ecological adaptation. Here, we studied the intestinal microbiota’s composition and functional differences using 16S rRNA and metagenomic analysis in the wild, farm, and released Chinese three-keeled pond turtle (Mauremys reevesii). At the phylum level, Bacteroidota dominated, followed by Firmicutes, Fusobacteriota, and Actinobacteriota in the wild group, but Chloroflexi was more abundant in the farm and released groups. Moreover, Chryseobacterium, Acinetobacter, Comamonas, Sphingobacterium, and Rhodobacter were abundant in the released and farm cohorts, respectively. Cetobacterium, Paraclostridium, Lysobacter, and Leucobacter showed an abundance in the wild group. The Kyoto Encyclopedia of Genes and Genomes (KEGG) database revealed that the relative abundance of most pathways was significantly higher in the wild turtles (carbohydrate metabolism, lipid metabolism, metabolism of cofactors, and vitamins). The comprehensive antibiotic resistance database (CARD) showed that the antibiotic resistance gene (ARG) subtype macB was the most abundant in the farm turtle group, while tetA was higher in the wild turtles, and srpYmcr was higher in the released group. Our findings shed light on the association between the intestinal microbiota of M. reevesii and its habitats and could be useful for tracking habitats to protect and conserve this endangered species.

Two-component systems (TCSs) widely exist in bacteria and assist bacteria in adjusting behaviors to adapt to environmental changes after sensing environmental signals and transducing information into cells. As a member of TCSs in Escherichia coli , after sensing signals, EvgS/EvgA mainly induces multiple resistances, such as acid and multidrug resistance, and increases bacterial adherence. Notably, the EvgS is one of the five unorthodox sensors in E. coli , which has an internal phosphorelay based on the structure with extra domains different from other orthodox sensors. Here, we summarize research on EvgS and EvgA published since 1994. This review includes comprehensive knowledge of EvgS/EvgA and focuses on the EvgS structure and the multiple resistance conferred by EvgS/EvgA. Furthermore, we discuss the unsolved questions of EvgS/EvgA and propose assumptions and inferences on the EvgS structure and the EvgS/EvgA function. IMPORTANCE EvgS/EvgA, one of the five unorthodox two-component systems in Escherichia coli , plays an essential role in adjusting bacterial behaviors to adapt to the changing environment. Multiple resistance regulated by EvgS/EvgA endows bacteria to survive in adverse conditions such as acidic pH, multidrug, and heat. In this minireview, we summarize the specific structures and regulation mechanisms of EvgS/EvgA and its multiple resistance. By discussing several unresolved issues and proposing our speculations, this review will be helpful and enlightening for future directions about EvgS/EvgA.
