TL;DR: A theoretical model is proposed to summarize and illustrate mechanisms by which specific bacterial–bacterial and viral-bacterial interactions that occur in the upper respiratory niche might be mediated and provide better insight into the pathogenesis of respiratory diseases.

TL;DR: It is found that immunity to pneumococcal colonization can be induced in the absence of antibody, independent of the capsular type, and this protection requires the presence of CD4(+) T cells at the time of challenge.

TL;DR: An association between increased carriage prevalence and resistance to non-opsonic neutrophil-mediated killing is found and non-vaccine serotypes that have become common in vaccinated populations tend to be those with fewer carbons per repeat units and low energy expended per repeat unit, suggesting a novel biological principle to explain patterns of serotype replacement.

TL;DR: This study suggests that, despite the results of susceptibility testing, all tetracycline-resistant S. aureus isolates should be treated as resistant to doxycycline, and all tetM-positive isolatesshould be treatedAs resistant to all termacyclines.

TL;DR: Catalase eliminated the bactericidal activity of Streptococcus pneumoniae toward Staphylococcus aureus and provided a possible mechanistic explanation for the interspecies interference observed in epidemiologic studies.
