<bold>Introduction</bold>
: Middle East respiratory coronavirus (MERS-CoV) causes respiratory disease in man, often resulting in severe or even fatal pneumonia. Rabbits are susceptible to MERS-CoV after simultaneous intratracheal and intranasal inoculation. Therefore, rabbits are a useful animal model for study of the pathogenesis of infection and preventive and therapeutic countermeasures for human patients. However, virus tropism and the course of disease in rabbits infected only via the nose are unknown.</p>
<p id="p0015">
<bold>Materials and Methods</bold>
: To compare different inoculation routes, 12 rabbits were divided into four groups and inoculated with MERS-CoV as follows: intratracheal with 3 ml and intranasal with 0.2 ml, intranasal with 1 ml or with 0.2 ml of MERS-CoV, or with 1 ml of PBS. Swabs were taken daily and at 4 days after inoculation the animals were killed, subjected to necropsy examination and sampled for histopathology, immunohistochemistry and virology.</p>
<p id="p0020">
<bold>Results</bold>
: Rabbits inoculated via the intranasal route with 1 ml of virus had infectious virus titres and high viral loads by PCR in nose swabs from 1 to 4 days after inoculation and in nasal turbinates and lungs at necropsy examination. Immunohistochemistry demonstrated virus antigen in nasal and pulmonary epithelial cells associated with inflammation.</p>
<p id="p0025">
<bold>Conclusions</bold>
: Rabbits can be infected via the intranasal route and have comparable virus tropism, virus load and inflammation as is seen in rabbits with additional intratracheal inoculation. Therefore, rabbits inoculated via the intranasal route can be used as a model to study the pathogenesis and intervention strategies for human disease.</p>
