Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China, in December 2019. Despite the recent introduction of vaccines against SARS-CoV-2, more effective vaccines and antiviral drugs must be developed. Here, we isolated five SARS-CoV-2 strains from four patients with coronavirus disease (COVID-19) and an asymptomatic individual using pharyngeal swabs, nasopharyngeal swabs, and sputum samples. Cytopathic effects in inoculated Vero cells were observed between days 3 and 7. SARS-CoV-2 infection was confirmed by quantitative reverse-transcription polymerase chain reaction (RT-qPCR) and next-generation sequencing. Phylogenetic analyses of the whole genome sequences showed that the virus isolates from the clinical samples belonged to the Wuhan and European lineages. These findings and the isolated viruses may contribute to the development of diagnostic tools, vaccines, and antiviral drugs for COVID-19.

β2 and β3 adrenergic receptor (β2AR, β3AR) and uncoupling protein 1 (UCP1) have been considered as candidate genes for obesity. Although each polymorphism of β3AR Trp64Arg, β2AR Arg16Gly and UCP1 -3826A>G is known to be associated with obesity, the interaction among these polymorphisms is not fully understood. We analyzed β3AR Trp64Arg, β2AR Arg16Gly and UCP1 -3826A>G polymorphisms by the Smart Amplification Process 2 in 222 Japanese subjects without the medication of hypertension, dyslipidemia or diabetes, and investigated the association between the physical and metabolic characteristics and the combination of these polymorphisms. In analysis of the genotypes combination, only the carriers of both β2AR Arg/Arg and UCP1 G/G genotypes had significantly higher waist to hip ratio (p=0.014). In analysis of the alleles combination, a significant difference was observed in waist to hip ratio among the groups stratified by the carrying number of the alleles of β3AR Arg, β2AR Arg and UCP1 G (p=0.026), and the waist to hip ratio was significantly higher in the carriers of four and five risk alleles than in the carriers from zero to three risk alleles (p=0.005). The present study demonstrated the interaction among β3AR Trp64Arg, β2AR Arg16Gly and UCP1 -3826A>G for the accumulation of visceral fat.
