Real-time reverse transcription-PCR (RT-PCR) is currently the most sensitive method to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes disease 2019 (COVID-19). However, correlation between detectable viral RNA and culturable virus in clinical specimens remains unclear. Here, we performed culture for 60 were confirmed be positive SARS-CoV-2 by real-time RT-PCR. The could successfully isolated from 12 throat nine nasopharyngeal swabs two sputum specimens.
Taiwan experienced two waves of imported infections with Coronavirus Disease 2019 (COVID-19). This study aimed at investigating the genomic variation severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in and compared their evolutionary trajectories global strains. We performed culture full-genome sequencing SARS-CoV-2 strains followed by phylogenetic analysis. A 382-nucleotides deletion open reading frame 8 (ORF8) was found a Taiwanese strain isolated from patient on February 4,...
We provide the first evidence for role of ACSL4 in enterovirus replication organelle formation. Moreover, both enteroviruses and coronaviruses induce ferroptosis via ACSL4. These findings establish a novel regulatory mechanism viral replication. The inhibition by inhibitors can reduce yields coronaviruses, including SARS-CoV-2, implying that ACSL4-mediated is promising therapeutic target diseases.

We aimed to identify AHE-specific microbiome association patients' outcomes.MethodsWe profiled fecal changes for cohort 62 patients with cirrhosis AHE i) before treatment, ii) 2-3 days after medication iii) months recovery, three control cohorts healthy individuals, compensated or decompensated...
Abstract Background Emergence of antibiotic resistance in bacteria is an important threat to global health. Antibiotic genes (ARGs) are some the key components define bacterial and their spread different environments. Identification ARGs, particularly from high-throughput sequencing data specimens, state-of-the-art method for comprehensively monitoring evolution. Current computational methods identify ARGs mainly rely on alignment-based sequence similarities with known ARGs. Such approaches...
Recent studies have detected mutations in the EDA gene, previously identified as causing X-linked hypohidrotic ectodermal dysplasia (XLHED), two families with non-syndromic hypodontia. Notably, all affected males both exhibited isolated oligodontia, while almost female carriers showed a milder or normal phenotype. We hypothesized that gene could be responsible for sporadic oligodontia males. In this study, we examined 15 unrelated oligodontia. Three novel (p.Ala259Glu, p. Arg289Cys, and...
Human enterovirus D68 (EV-D68) was first reported in the United States 1962; thereafter, a few cases were from 1970 to 2005, but 2 outbreaks occurred Philippines (2008) and (2014). However, little is known regarding molecular evolution of this globally reemerging virus due lack whole-genome sequences analyses. Here, all publically available including 147 full 1248 partial genomes GenBank collected compared at clade subclade level; 11 whole isolated Taiwan (TW) 2014 also added database....
Abstract Since April 2022, waves of SARS-CoV-2 Omicron variant cases have surfaced in Taiwan and spread throughout the island. Using high-throughput sequencing genome, we analyzed 2,405 PCR-positive swab samples from 2,339 persons identified BA.2.3.7 as a major lineage within recent community outbreaks Taiwan.
Enteroviruses are well known for their ability to cause neurological damage and paralysis. The model enterovirus is poliovirus (PV), the causative agent of poliomyelitis, a condition characterized by acute flaccid A related virus, 71 (EV-A71), causes similar clinical outcomes in recurrent outbreaks throughout Asia. Retrospective phylogenetic analysis has shown that recombination between circulating strains EV-A71 produces outbreak-associated which exhibit increased virulence and/or...
ABSTRACT The NS1 protein encoded by influenza A virus antagonizes the interferon response through various mechanisms, including blocking cellular mRNA maturation binding CPSF30 3′ end processing factor and/or suppressing activation of regulatory 3 (IRF3). In present study, we identified two truncated proteins that are translated from internal AUGs at positions 235 and 241 open reading frame. We analyzed localization function N-truncated strains, Udorn/72/H3N2 (Ud) Puerto Rico/8/34/H1N1...
The circulation and the genomic evolution of influenza A(H3N2) viruses during 2021/2022 2022/2023 seasons were studied associated with infection outcomes.
An avian influenza A H7N9 virus emerged in March 2013 and caused a remarkable number of human fatalities. Genome variability these viruses may provide insights into host adaptability. We scanned over 140 genomes the isolated from humans identified 104 positions that exhibited seven or more amino acid substitutions. Approximately half substitutions were ribonucleoprotein (RNP) complex. Although PB2 627K promotes replication humans, 45 147 investigated sequences retained E signature at this...
It has been observed that variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are more stable and infectious after storage at −20°C than 4°C. A SARS-CoV-2 S-D614G variant is currently the most dominant in circulation associated with enhanced infectivity.
Herein, we present a new approach for serological testing SARS-CoV-2 antibodies using innovative laboratory methods that demonstrate combination of biology and mathematics. The traditional virus neutralization test is the gold standard method; however, it time-consuming poses risk to medical personnel.
Abstract Enteroviruses (EVs), single‐stranded, positive‐sense RNA viruses, can be classified into four species (A−D), which have previously been linked to a diverse range of disease manifestations and infections affecting the central nervous system. In Enterovirus B (EV‐B), Echovirus type 11 (E11) has observed occasionally circulate in Taiwan, was responsible for an epidemic enterovirus 2018. Here, 48 clinical specimens isolated 2003, 2004, 2009, 2018 were collected high‐throughput...
