Abstrakt: The use of museum preserved specimens to know microbiome in extinct and threatened species has been explored recently. The fishes of the genus Herichthys are distributed mainly in the Pánuco-Tamesí system in Northeastern Mexico, one of the most polluted basins in the country leading to near half of the species be considering as threatened. In this paper we used the hypervariable V4 region of the 16S rRNA gene from the 11 species of the genus Herichthys obtained from museum collections to evaluate the potential use of fixed preserved vouchers in the knowledge of gut microbiota diversity and the potential role of sympatric and allopatric speciation of the hosts in the gut microbiome evolution. The 100% of the samples were successfully amplified where the number of amplicons ranged from 4500 from a formaldehyde fixed specimen up to 55,000 in ethanol preserved specimens. Differences in gut microbiota were found between sympatric species and among the comparison of some trophic guilds. A non-random association between the gut host and their microbiome was found allow to suggest a potential phylosymbiosis relationship. In conclusion, the most abundant phyla recovered from the gut microbiota in this study were similar to those previously reported in other cichlids supporting the idea that a gut microbial core is conserved in this group of fishes despite millions of years of evolution and leading to support the potential use of museum specimens in microbiome studies.
