The close genetic and antigenic relatedness among the group 2 coronaviruses human coronavirus OC43 (HCoV-OC43), bovine coronavirus (BCoV), and porcine hemagglutinating encephalomyelitis virus (PHEV) suggests that these three viruses with different host specificities diverged fairly recently. In this study, we determined the complete genomic sequence of PHEV (strain PHEV-VW572), revealing the pr...
1181 LETTERS Her hemoglobin level had dropped further to 8.4 g/dL. Sputum culture yielded substantial growth of methi-cillin-sensitive Staphylococcus aureus and Pseudomonas aeruginosa. RT-PCR results of throat and nasal swabs were positive twice for coronavirus, but coronavirus cultures from these areas were negative. One month after onset, her coronavirus antibody titer was 200. In view of pos...
Six cell lines routinely used in laboratories were tested for permissiveness to the infection with the newly identified human coronavirus NL63. Two monkey epithelial cell lines, LLC-MK2 and Vero-B4, showed a cytopathic effect (CPE) and clear viral replication, whereas no CPE or replication was observed in human lung fibroblasts MRC-5s. In Rhabdomyosarcoma cells, Madin-Darby-Canine-kidney cells ...
This paper is based on two recent publications (1,2), and one submitted for publication (submittted for publication). There is an important correction. In the two previous publications in Nephron it was stated that the virus isolated from the kidneys, the tumors and metastatic lymph glands was classified as a coronavirus (1,2). Subsequent more detailed investigations revealed that the virus sho...
The World Health Organization (WHO) published 2 alcohol-based formulations to be used in healthcare settings and for outbreak-associated infections, but inactivation efficacies of these products have not been determined against (re-)emerging viruses. In this study, we evaluated the virucidal activity of these WHO products in a comparative analysis. Zika virus (ZIKV), Ebola virus (EBOV), severe ...
CDC continues to work closely with the World Health Organization (WHO) and other partners to better understand the public health risk posed by a novel coronavirus that was first reported to cause human infection in September 2012. Genetic sequence analyses have shown that this new virus is different from any other known human coronaviruses, including the one that caused severe acute respiratory...
Coronaviruses are closely monitored in the context of emerging diseases and, as illustrated with Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle East Respiratory Syndrome-coronavirus (MERS-CoV), are known to cross the species barrier and eventually to move from wildlife to humans. Knowledge of the diversity of coronaviruses in wildlife is therefore essential to better unders...
Background: Since April 2012, Middle East Respiratory Syndrome Coronavirus (MERS-CoV) has been confirmed in 8 countries: France, Italy, Jordan, Qatar, Saudi Arabia, Tunisia, United Kingdom (UK) and United Arab Emirates (UAE). Of 55 laboratory-confirmed cases, 31 were fatal for a case fatality rate of 56% (current CDC data June 7, 2013). Although no cases have been reported in the US as of June ...
Human coronavirus OC43 (HCoV-OC43) is one of five currently circulating human coronaviruses responsible for respiratory infections. Like all coronaviruses, it is characterized by its genome's high plasticity. The objectives of the current study were to detect genetically distinct genotypes and eventually recombinant genotypes in samples collected in Lower Normandy between 2001 and 2013. To this...
