Epidemiology of Giardia intestinalis in non-human primates and their caregivers: A study from Czech zoos
Original language description
Giardia intestinalis is a globally distributed protist whose epidemiology appears to be more complex than previously assumed. Recent studies suggest that it frequently asymptomatically colonizes the gastrointestinal tract of both humans and animals, yet its transmission dynamics remain poorly understood—particularly in shared environments involving close human–animal contact. Adopting a One Health perspective, this study investigated the occurrence of G. intestinalis in captive non-human primates (NHPs) and their caregivers across six zoological gardens in the Czech Republic, with a particular focus on the potential for zoonotic transmission. A total of 179 fecal samples (159 from 37 NHP species and 20 from caregivers) were analyzed using qPCR. Giardia was detected in 47 % of NHPs and 30 % of caregivers. Assemblage B was the most frequently identified genotype however, genotyping was challenging in samples with low fecal protist load, limiting the ability to accurately assess transmission pathways. These findings reveal a high prevalence of G. intestinalis in zoo environments and underscore the importance of improved genotyping tools and further research into its transmission across species boundaries in human-managed settings.
