The microbiota of the nasopharyngeal tract (NT) play a role in host immunity against
respiratory infectious diseases. However, scant information is available on interactions of …

Objectives The COVID-19 pandemic and ensuing public health emergency has emphasized
the need to study SARS-CoV-2 pathogenesis. The human microbiome has been shown to …

We investigated nasopharyngeal microbial community structure in COVID-19-positive and-
negative patients. High-throughput 16S ribosomal RNA gene amplicon sequencing …

The development of novel culture-independent techniques of microbial identification has
allowed a rapid progress in the knowledge of the nasopharyngeal microbiota and its role in …

Coronavirus disease 2019 (COVID-19) remains a serious emerging global health problem,
and little is known about the role of oropharynx commensal microbes in infection …

The human organism is inhabited by trillions of microorganisms, known as microbiota, which
are considered to exploit a pivotal role in the regulation of host health and immunity. Recent …

While populations at risk for severe SARS-CoV-2 infections have been clearly identified,
susceptibility to the infection and its clinical course remain unpredictable. As the …

Emerging evidence suggests the oral and upper respiratory microbiota may play important
roles in modulating host immune responses to viral infection. As the host microbiome may …

COVID-19 remains a serious emerging global health problem, and little is known about the
role of oropharynx commensal microbes in infection susceptibility and severity. Here, we …

Abstract Background Infection with SARS-CoV-2 may perturb normal microbiota, leading to
secondary infections that can complicate the viral disease. The aim of this study was to …
