Oral-fecal mycobiome in wild and captive cynomolgus macaques (Macaca fascicularis).

Cynomolgus macaque (Macaca fascicularis) is currently a common animal model for biomedical research. The National Primate Research Center of Thailand, Chulalongkorn University (NPRCT-CU) translocated wild-borne macaques to reared colony for research purposes. At present, no studies focus on fungal microbiome (Mycobiome) of this macaque. The functional roles of mycobiome and fungal pathogens have not been elucidated. Thus, this study aimed to investigate and compare oral and fecal mycobiome between wild and captive macaques by using high-throughput sequencing on internal transcribed spacer 2 (ITS2) rDNA. The results showed that the mycobiome of wild macaque has greater alpha diversity. The fecal mycobiome has more limited alpha diversity than those in oral cavity. The community is mainly dominated by saprophytic yeast in Kasachstania genus which is related to aiding metabolic function in gut. The oral microbiome of most captive macaques presented the Cutaneotrichosporon suggesting the fungal transmission through skin-oral contact within the colony. The potential pathogens that would cause harmful transmission in reared colonies were not found in either group of macaques but the pathogen prevention and animal care is still important to be concerned. In conclusion, the results of gut mycobiome analysis in Thai cynomolgus macaques provide us with the basic information of oral and fecal fungi and for monitoring macaque's health status for animal care of research use.
