Further evidence for bats as a major source of CoVs came in a recent study in Emerging Infectious Diseases. Yang and colleagues identified a novel CoV from each of 2 bat species.
The newly identified betacoronaviruses (betaCoVs), Bat Rp-coronavirus/Shaanxi2011 and Bat Cp-coronavirus/Yunnan2011 (rolls of the tongue doesn't it?) were not that closely related to human betaCoVs but resided in the bat verison of the SARS-like COVs.
