T41 0-120 Sentence denotes Coronaviruses are a group of related viruses in the family Coronaviridae and subfamily Coronavirinae, order Nidovirales.
T42 121-268 Sentence denotes In the subfamily Coronavirinae, coronaviruses include 4 genres: alphacoronavirus, betacoronavirus, gammacoronavirus and deltacoronavirus (Fig. 1 ).
T43 269-370 Sentence denotes Coronaviruses infect a wide variety of hosts including many species of birds, mammals and humans [7].
T44 371-504 Sentence denotes Alphacoronaviruses and betacoronaviruses circulate among mammals, gammacoronaviruses and deltacoronaviruses infect birds and mammals.
T45 505-853 Sentence denotes Within betacoronaviruses, there are 4 lineages: lineage A contains human coronaviruses HKU1 and OC43, lineage B to which SARS-CoV (Severe Acute Respiratory Syndrome Coronavirus) belongs, lineage C belongs to MERS-CoV (Middle East Respiratory Coronavirus Syndrome) and the lineage D has the bat coronaviruses HKU4 and HKU5 who are close to MERS-CoV.
T46 854-953 Sentence denotes Fig. 1 Isolates of coronaviruses discussed in this review and their receptors, host and reservoirs.
T47 954-1018 Sentence denotes SARS-CoV and SARS-CoV-2 from the lineage B use ACE2 as receptor.
T48 1019-1086 Sentence denotes MERS-CoV from the lineage C enters into host cells by binding DPP4.
T49 1087-1252 Sentence denotes SARS-CoV has the masked palm civets as an intermediate host in which the virus has adapted from the Chinese Horseshoe bat reservoir to ultimately infect humans [13].
T50 1253-1393 Sentence denotes SARS-CoV-2 has bats and pangolins as natural reservoir and can infect ferrets or domestics animals, with a high susceptibility in cats [14].
T51 1394-1524 Sentence denotes MERS-CoV has the origin from bats [15] but maybe this virus had an adaptation through camels before its emergence into human [16].
