Nature Communications, Published online: 25 October 2021; doi:10.1038/s41467-021-26244-5
Antibiotic resistance in Staphylococcus aureus is associated with reduced neutrophil recruitment. Here, Payne et al. link formylated peptides, which act as chemoattractants for neutrophils, with the antibiotic vancomycin and show that these hybrid compounds improve clearance of S. aureus by neutrophils.Proteomic analysis of the host–pathogen interface in experimental cholera

Role of bile acids and gut bacteria in healthy ageing of centenarians
Nature, Published online: 06 October 2021; doi:10.1038/d41586-021-02196-0
A study in humans indicates that certain bile acids that are produced by bacteria and commonly found in people over 100 boost gut health and protect against infection. These findings shed light on the contributors to healthy ageing.A single sulfatase is required to access colonic mucin by a gut bacterium
