3. Giardia duodenalis in farmed exotic animals

Several studies were conducted to assess the prevalence and genotype identity of G. duodenalis in farmed raccoon dogs, bamboo rats, and macaque monkeys in China. Low infections rates were obtained from most studies ( Table 2). Two studies, however, showed common occurrence of G. duodenalis in farmed crab-eating macaques (32.3%) in Hainan and bamboo rats (10.8%) in Hunan. Younger animals and animals with diarrhea had higher infection rates than older animals and animals with normal stools ( Chen et al., 2019b; Ma et al., 2018). Infected raccoon dogs mostly had assemblage C, while macaque monkeys and bamboo rats mostly had assemblage B ( Table 2). There was a high genetic diversity among assemblage B and C isolates in all these studies ( Chen et al., 2019b; Karim et al., 2014c; Ma et al., 2018; Ye et al., 2014; Zhang et al., 2016d). In one study of G. duodenalis in crab-eating macaques on one farm, 53 multi-locus genotypes were found. Most of them were genetically related to those previously seen in Old-World monkeys ( Chen et al., 2019b; Karim et al., 2014c).
