One of the current threats to the bonobo (Pan paniscus), a highly endangered ape species only found in the Democratic Republic of the Congo, are anthropozoonoses caused by human respiratory viruses. To date, epidemiological information regarding respiratory viral infections in bonobos is limited. In this study, we examined fecal immunoglobulin A antibodies against human respiratory viruses in bonobos, which may help estimating the viral prevalence. A substantial proportion of bonobos were positive for the antiviral antibodies, including those against parainfluenza virus, respiratory syncytial virus, influenza virus, rhinovirus, and mumps virus. The prevalence of the antibodies was found to depend on the viral species and bonobo populations, suggesting that the bonobos had been exposed to these respiratory viruses. These results may indicate the need for an epidemiological evidence-based action plan for the protection of bonobos from anthropozoonoses.
