An African pygmy hedgehog adenovirus 1 (AhAdV-1) outbreak in an African pygmy hedgehog (Atelerix albiventris) colony in Japan.

ABSTRACT: An African pygmy hedgehog adenovirus 1 (AhAdV-1) outbreak in a colony of 24 African pygmy hedgehogs (APHs) with a case of fatal pneumonia occurred in Japan. Thirteen out of a colony of 15 APHs with respiratory symptoms were diagnosed with AhAdV-1 infection based on the detection of AhAdV-1 genome in throat/nasal swabs and further one APH was diagnosed on isolation of the virus. Five infected APHs died during the outbreak and AhAdV-1 caused severe pneumonia and death in one case. After the outbreak, persistent AhAdV-1 infection was suggested in one surviving APH. AhAdV-1 is a novel adenovirus and is suspected to be an emerging pathogen.

Project description:African pygmy hedgehogs (Atelerix albiventris) are widely farmed in southern China and Japan for medicinal materials and as pets. However, little is known about the prevalence, zoonotic potential, and environmental burden of Cryptosporidium spp., Enterocytozoon bieneusi and Giardia duodenalis in these animals. In this study, 380 fecal samples were collected from farmed and pet African pygmy hedgehogs in Guangdong of China, and analyzed for these pathogens by PCR and DNA sequencing. Overall, the detection rates of Cryptosporidium spp., E. bieneusi and G. duodenalis were 35.5%, 70.0% and 0, respectively. By living condition, the highest detection rates of Cryptosporidium spp. (61.5%) and E. bieneusi (100.0%) were both obtained from animals kept in the cave, which could be due to the overcrowding and poor hygiene conditions. Two Cryptosporidium species were identified, including C. erinacei (n = 22) and Cryptosporidium horse genotype (n = 113). The C. erinacei isolates belonged to a new subtype family (XIIIb), which has been identified in a patient with cryptosporidiosis recently. The horse genotype isolates are of a known subtype VIbA13, which was previously identified in a pet store employee in care of hedgehogs with diarrhea. Eleven genotypes of the zoonotic Group 1 were identified in E. bieneusi, with the known genotype SCR05 previously detected in pet rabbits being dominant (235/266, 88.3%). In longitudinal monitoring of Cryptosporidium infection in 11 naturally infected African pygmy hedgehogs, the oocyst shedding intensity decreased gradually from the mean oocysts per gram of feces of ∼6 logs to ∼2 logs over 42 days. The high intensity and long duration of oocyst shedding could lead to heavy environmental contamination and increase the potential for zoonotic transmission of the pathogens. Results of the study suggest that zoonotic Cryptosporidium spp. and E. bieneusi are common in farmed and pet African pygmy hedgehogs. Hygiene and One Health measures should be implemented by pet owners and farmers to prevent zoonotic transmission and environmental contamination of Cryptosporidium spp. and E. bieneusi.
