Study shows SARS-CoV-2 infection can change nasopharyngeal microbiota composition in pregnancy

A recent study from Spain showed that the infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can change the overall structure and diversity of the nasopharyngeal microbiota in pregnant women – which persists even weeks after clinical infection. The paper is currently available on Research Square preprint* server.

Study explores lectins from plants, fungi, algae and cyanobacteria as pan-coronavirus inhibitors

In a recently published article scientists have provided a detailed description of the utility of mannose-specific lectins in preventing coronavirus infections. They have specifically explained how mannose-specific lectins derived from plants, algae, fungi, and bacteria selectively bind N-glycans present on the surface of viral spike protein and how such interactions can be medically utilized to control coronavirus transmission.

Study provides evidence of aerosol exposure to microcystins among coastal residents

Florida has experienced numerous harmful algal blooms in recent years, including blue-green algae and their toxins in 2016 and 2018. Despite their intensity and frequency, there is scant data on human exposure to these blooms and concentrations of the toxins they produce in tissues of exposed individuals.
