“…Indeed, field voles (Microtus agrestis), bank voles (Myodes glareolus), wood mice (Apodemus sylvaticus), and shrews (Sorex araneus), which are particularly susceptible to M. microti infection, constitute its natural reservoirs (1). However, an increasing number of cases have also been reported in domestic and wild mammals (2), such as cats (3,4), pigs (5), European wild boar (Sus scrofa) (6), ferrets (Mustela putorius), badgers (Meles meles) (4), New World camelids (Lama glama and Vicugna pacos) (4), squirrel monkeys (Saimiri sciureus) (7), meerkats (Suricata suricatta) (8), and a dog (9). Until now, 27 cases of M. microti infection in both immunocompetent (10) and immunocompromised human patients (11) have been described (12), demonstrating its capacity for causing clinical illness and thus for being a potential zoonotic agent.…”
