Neutrophil interactions with Streptococcus pyogenes and Staphylococcus aureus
... In conclusion, our finding points towards different mechanisms for the two BCLs LukED and PVL upon interaction with neutrophils. While the cytotoxic and degranulation response towards LukED is dose-dependent, PVL induced ...

Novel Genes Required for the Fitness of Streptococcus pyogenes in Human Saliva
... To test the hypothesis that inactivating each of these six genes impaired GAS fitness in human saliva ex vivo, we used targeted insertional mutagenesis (31, 34, 35) to create isogenic mutant strains from wild-type ...
