Simple Summary

Dozens of species of small exotic mammals, such as chinchillas, golden hamsters, Java squirrels, Mongolian gerbils, mice, rats, African hedgehogs, and sugar gliders, are kept as pets globally. These exotic companion mammals are potential reservoirs for maintaining and transmitting zoonotic pathogens. Using molecular assays, our study aimed to investigate the occurrence of some potential zoonotic viruses in various small exotic mammals kept as pets in Italy. Our findings show that aichivirus (AiV) was further characterized as murine kobuvirus-1 in a rat (Rattus norvegicus). To the best of our knowledge, this is the first study reporting the detection of AiV in rodents in Italy. Our results also revealed the absence of other viruses investigated while highlighting the importance of ongoing monitoring of infectious agents in these increasingly common pets to prevent the spread of new potential zoonotic pathogens.

Abstract

We investigated the occurrence of eight potential zoonotic viruses in 91 exotic companion mammals from pet shops in southern Italy via real-time PCR and end-point PCR. The animals were screened for aichivirus, sapovirus, astrovirus, hepatitis A, noroviruses (GI and GII), rotavirus, circovirus, and SARS-CoV-2. Among the nine species of exotic pets studied, only one rat tested positive for aichivirus. The high sequence similarity to a murine kobuvirus-1 strain previously identified in China suggests that the virus may have been introduced into Italy through the importation of animals from Asia. Since exotic companion mammals live in close contact with humans, continuous sanitary monitoring is crucial to prevent the spread of new pathogens among domestic animals and humans. Further investigations on detecting and typing zoonotic viruses are needed to identify emerging and re-emerging viruses to safeguard public health.
