Antibiotics provide no benefit in preventing recurrent wheezing in infants hospitalized with RSV

Antibiotics provide no benefit in preventing future recurrent wheezing in babies hospitalized with respiratory syncytial virus (RSV), according to a new study led by Washington University School of Medicine in St. Louis. And there is some evidence that antibiotics may make wheezing worse.

Study finds reductions in hospital admissions for childhood infections during first year of pandemic

During the first year or so of the covid-19 pandemic, there were dramatic reductions in hospital admissions for common and severe childhood infections in England, most likely due to social distancing measures, school and workplace closures, and travel restrictions, finds a study published by The BMJ today.

Emergency workers who attended the World Trade Center site early are at risk of developing COPD

Twenty years on from the September 11 attacks, rescue and recovery workers and volunteers who attended the World Trade Center site are beginning to develop chronic obstructive pulmonary disease (COPD) often following a previous diagnosis of asthma, according to research presented at the European Respiratory Society International Congress.

White-tailed deer are highly susceptible to SARS-CoV-2 infection

The SARS-CoV-2 virus has been shown to infect a wide range of animals naturally and experimentally, and prior studies indicate deer are susceptible to infection. White-tailed deer (Odocoileus virginianus) fawns have been found to be susceptible to SARS-CoV-2.

SARS-CoV-2 variants show distinct humoral response and transcriptional profiles in hamster model

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel, highly infectious respiratory virus, and the causative agent of coronavirus disease 2019 (COVID-19) pandemic. SARS-CoV-2, which first originated in Wuhan, in Hubei province of China, is a member of the Coronavirdae family and has a large, non-segmented RNA genome.

Facets of SARS-CoV-2 infection and animal models

A new study in the journal Frontiers in Cell and Developmental Biology discusses the ribonucleic acid (RNA) genome of the virus, and the mechanisms by which it establishes infection within the host cell. The researchers also summarize the development of animal models of COVID-19, which will both help understand the clinical features of the illness, and indicate new approaches for the treatment of the infection.

Microbiota-derived molecules do not change the entry or replication of SARS-CoV-2 in intestinal cells

A study conducted at the University of Campinas in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines.
