• the 50% infectious dose of MERS-CoV EMC/2012 strain
• mice surviving MERS-CoV infection develop serum neutralizing antibody and MERS-CoV S1 protein-specific IgG antibodies by 21 dpi and are fully immune to challenge with 103 TCID50
(J:227925)
• most mice immunized with a MERS-CoV receptor binding domain-based subunit vaccine S377-588l-Fc plus MF59 adjuvant before being challenged with MERS-CoV recover from mild morbidity and survive
(J:227925)
• intranasal administration of a fusion inhibitor peptide HR2M6 before challenge with MERS-CoV results in reduced lung viral titers and protection from death
(J:227925)
• administration of HR2M6 after exposure to MERS-CoV does not provide therapeutic benefit
(J:227925)
• mice are susceptible to infection with the EMC-2012 strain of the Middle East respiratory-coronavirus (MERS-CoV)
• mice infected with MERS-CoV develop disseminated infection, with lung and brain being the prime sites of intense viral infection, and viral RNA detected in the heart, spleen, and intestine, but infectious virus could not be isolated from the heart, spleen, intestine, liver, and kidneys
(J:258199)
• lung alveolar pneumocytes, both type I and type II, and brain microglia, astrocytes, and neuronal cells express abundant viral antigen at 2 and 4 dpi

growth/size/body
• mice infected with 103 TCID50 or higher of MERS-CoV show extreme weight loss of more than 20% while a dose of 102 results in less than 8% weight loss
