Although small animal models for MERS-CoV are still lacking(Devitt, 2013), researchers have made great progress towards theidentification and development of an effective small animal model for MERS-CoV infections. In particular, it has been shown that mice are susceptible to MERS-CoV infection after prior transduction with an adenoviral vector expressing the receptor of MERS-CoV,human DPP4, with infected mice developing pneumonia accom-panied by inflammatory cell in filtration and histopathological changes
