claim: bacterial modification of the host glycosaminoglycan heparan oxide modulates sars-cov-2 infectivity
evidence_1: in vitro , bacterial glycosidases from unpurified culture media supernatants fully blocked sars-cov-2 spike binding to human h1299 protein lung adenocarcinoma cells.", "understanding the impact of shifts in microbial community composition and bacterial lyases on sars-cov-2 infection may lead to new therapeutics and diagnosis of susceptibility.")
