Abstract

The newly emerged Middle East respiratory syndrome coronavirus (MERS-CoV) infects human bronchial epithelial Calu-3 cells. Unlike severe acute respiratory syndrome (SARS)-CoV, which exclusively infects and releases through the apical route, this virus can do so through either side of polarized Calu-3 cells. Infection results in profound apoptosis within 24 h irrespective of its production of titers that are lower than those of SARS-CoV. Together, our results provide new insights into the dissemination and pathogenesis of MERS-CoV and may indicate that the virus differs markedly from SARS-CoV.
