Complete genome analysis of a SARS-like bat coronavirus identified in the Republic of Korea

In conclusion, we firstly carried out whole genome characterization of the SARS-like bat coronavirus discovered in the Republic of Korea; however, it presumably has no human infectivity. However, continuous surveillance and genomic characterization of coronaviru ses from bats are necessary due to potential risks of human infection induced by genetic mutation.

AbstractCoronaviruses are a large family of viruses that are known to infect both humans and animals. However, the evidence of inter-transmission of coronavirus between humans and companion animals is still a debatable issue. There is substantial evidence that the virus outbreak is fueled by zoonotic transmission because this new virus belongs to the same family of viruses as SARS-CoV associated with civet cats, and MERS-CoV associated with dromedary camels. While the whole world is investigating the possibility about the transmission of this virus, the transmission among humans is established, but the interface between hu...

Abstract The recurrent emergence of novel, pathogenic coronaviruses (CoVs) SARS-CoV-1 (2002), MERS-CoV (2012) and most recently SARS-CoV-2 (2019) has highlighted the need for physiologically informative airway epithelial cell infection models for studying immunity to CoVs and development of anti-viral therapies. To address this, we developed an in-vitro infection model for two human coronaviruses; alphacoronavirus 229E-CoV (229E) and betacoronavirus OC43-CoV (OC43) in differentiated primary human bronchial epithelial cells (pBECs). Primary BECs from healthy subjects were grown at air liquid interface (ALI) and inf...

In the last decades, a number of infectious viruses have emerged from wildlife or re-emerged, generating serious threats to the global health and to the economy worldwide. Ebola and Marburg hemorrhagic fevers, Lassa fever, Dengue fever, Yellow fever, West Nile fever, Zika, and Chikungunya vector-borne diseases, Swine flu, Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the recent Coronavirus disease 2019 (COVID-19) are examples of zoonoses that have spread throughout the globe with such a significant impact on public health that the scientific community has been called for a rapid int...

Human coronaviruses (HCoVs) are of zoonotic origins, and seven distinct HCoVs are currently known to infect humans. While the four seasonal HCoVs appear to be mildly pathogenic and circulate among human populations, the other three designated SARS-CoV, MERS-CoV, and SARS-CoV-2 can cause severe diseases in some cases. The newly identified SARS-CoV-2, a causative virus of COVID-19 that can be deadly, is now spreading worldwide much more efficiently than the other two pathogenic viruses. Despite evident differences in these properties, all HCoVs commonly have an exceptionally large genomic RNA with a rather peculiar gene orga...

Abstract Coronavirus Disease 2019 (COVID-19) caused by a Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) was first reported in Wuhan, China at the end of December 2019. SARS-CoV-2 is a highly pathogenic zoonotic virus and closely related to the Severe Acute Respiratory Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome Coronavirus (MERS-CoV). The COVID-19 was declared as a global pandemic due to its high infectiousness, and worldwide morbidities and mortalities. The Chinese scientists at the start of the outbreak reported genome sequences, which made the characterization of glycoproteins and ...

Abstract Virus onslaughts continue to spread fear and cause rampage across the world every now and then. The twenty first century is yet again witnessing a gross global pandemic, Coronavirus Disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Globally no vaccines or drug specific to COVID-19 is available. Corona viruses have been in mutual relationship with humans and other hosts over many decades though aggressive zoonotic strains have caused havoc. Zoonotic emergent corona viruses prior to SARS-COV-2 included severe acute respiratory syndrome coronavirus (SARS-CoV) and...

Abstract Coronavirus is an enveloped, non-segmented, positive-polarity and single-stranded RNA virus. It has four types genera that infect mammals and birds, with only alpha and beta types found to affect humans with varying severity. A specific clade of beta coronaviruses are reported as lethal zoonotic viruses and have created major epidemic troubles, starting with the severe acute respiratory syndrome (SARS) in 2002, then the Middle East respiratory syndrome (MERS) in 2012, and lastly Coronavirus Disease 2019 (COVID-19) in 2019. However, many neurological complications reported in COVID19 patients have highligh...

It wasn’t greed, or curiosity, that made Li Rusheng grab his shotgun and enter Shitou Cave. It was about survival. During Mao-era collectivization of the early 1970s, food was so scarce in the emerald valleys of southwestern China’s Yunnan province that farmers like Li could expect to eat meat only once a year–if they were lucky. So, craving protein, Li and his friends would sneak into the cave to hunt the creatures they could hear squeaking and fluttering inside: bats. Li would creep into the gloom and fire blindly at the vaulted ceiling, picking up any quarry that fell to the ground, while his companion...

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a novel zoonotic pathogen. It is responsible for Coronavirus Disease 2019 (COVID-19) [1]. The COVID-19 pandemic has imposed a heavy burden on global health and medical systems [2]. A whole genome scan has shown that SARS-CoV-2 has a 79% similarity to Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), and a 50% similarity to Middle East Respiratory Syndrome Coronavirus (MERS-CoV) [3]. Currently, SARS-CoV-2 is classified as a SARS-associated coronavirus and taxonomically belongs to the subgenus of Sabek virus [3].
