Detection of in Common Marmoset () and Treatment with Metronidazole.

Background: Recently, the use of common marmoset () has increased in biomedical research as an animal model. This study aimed to test fecal samples to monitor bacterial and parasite infections in common marmoset at the Laboratory Animal Center of Osong Medical Innovation Foundation in Korea.

Methods: To monitor bacteria and parasites in common marmoset, we tested 43 fecal samples of 43 common marmosets by culture and parasitological test in 2014. Infection by was determined by PCR method.

Results: We identified nonpathogenic bacteria such as and in feces of normal common marmosets. Interestingly, was isolated from a healthy common marmoset by fecal centrifugation concentration and PCR. The monkey infected with was treated with metronidazole. After the treatment, were not found in feces using fecal centrifugation concentration and PCR.

Conclusion: This is the first case report of infection in common marmoset. Treatment with metronidazole is found to be highly effective in eradicating infection in common marmoset.
