We report the complete genome sequence of the first Mexican human coronavirus (HCoV) OC43, obtained by new-generation sequencing and a metagenomic approach, isolated from a child hospitalized with pneumonia. The genome is closely related to the other OC43 genome sequences available, ranging from 99.8% to 98.2% nucleotide sequence identity.
A vaccine for equine coronavirus (ECoV) is so far unavailable. Bovine coronavirus (BCoV) is antigenically related to ECoV; it is therefore possible that BCoV vaccine will induce antibodies against ECoV in horses. This study investigated antibody response to ECoV in horses inoculated with BCoV vaccine. Virus neutralization tests showed that antibody titers against ECoV increased in all six horse...
Middle East respiratory syndrome coronavirus (MERS-CoV) Infection, has caused recurrent outbreaks worldwide. It is associated with severe morbidity and mortality, and is not treatable with the currently available antiviral therapies. We present a case of a 43 year-old male healthcare provider, who admitted with productive cough, dyspnea, myalgia, pleuritic chest pain and fever. Computed tomogra...
We report the complete genome sequences of a buffalo coronavirus (BufCoV HKU26) detected from the faecal samples of two domestic water buffaloes (Bubalus bubalis) in Bangladesh. They possessed 98-99% nucleotide identities to bovine coronavirus (BCoV) genomes, supporting BufCoV HKU26 as a member of Betacoronavirus 1. Nevertheless, BufCoV HKU26 possessed distinct accessory proteins between spike ...
Global predictions of the secondary structure of coronavirus (CoV) 5' untranslated regions and adjacent coding sequences revealed the presence of conserved structural elements. Stem loops (SL) 1, 2, 4, and 5 were predicted in all CoVs, while the core leader transcription-regulating sequence (L-TRS) forms SL3 in only some CoVs. SL5 in group I and II CoVs, with the exception of group IIa CoVs, is...
Human coronaviruses cause both upper and lower respiratory tract infections in humans. In 2012, a sixth human coronavirus (hCoV) was isolated from a patient presenting with severe respiratory illness. The 60-year-old man died as a result of renal and respiratory failure after admission to a hospital in Jeddah, Saudi Arabia. The aetiological agent was eventually identified as a coronavirus and d...
Membrane fusion between virus and host cells is the key step for enveloped virus entry and is mediated by the viral envelope fusion protein. In murine coronavirus, mouse hepatitis virus (MHV), the spike (S) protein mediates this process. Recently, the formation of anti-parallel 6-helix bundle of the MHV S protein heptad repeat (HR) regions (HR1 and HR2) has been confirmed, implying coronavirus ...
A new coronavirus, MERS-CoV (Middle East Respiratory Syndrome-Coronavirus) which is related to the coronavirus that caused the SARS outbreak 10 years ago, has been discovered in Saudi Arabia and observed in several other countries since 2012. A mathematical model is constructed in order to theorize possible patterns of the spread of this emerging disease which seems to require an extended conta...
The Eastern Mediterranean Region of World Health Organization has been an emerging focus for global health after the discovery of a novel coronavirus infection in some countries in the Region. The Region has already witnessed a number of emerging zoonoses with epidemic potential. In view of this new virus, there is now an urgent need for strong public health vigilance and monitoring of the evol...
A human coronavirus, called the Middle East respiratory syndrome coronavirus (MERS-CoV), was first identified in September 2012 in samples obtained from a Saudi Arabian businessman who died from acute respiratory failure. Since then, 49 cases of infections caused by MERS-CoV (previously called a novel coronavirus) with 26 deaths have been reported to date. In this report, we describe a family c...
