Streptococcus pneumoniae is a leading cause of community-acquired pneumonia. Pneumococci are categorised into serotypes, based on the type of capsular polysaccharide produced, which has important implications for virulence, vaccine impact and global surveillance. In this study, the authors report and describe variants of serotype 33G, designated 33G-like, which they isolated from the nasopharynx of two adults hospitalised with pneumonia in Mongolia.

Aims and scope
Pneumonia is the only journal to focus exclusively on pneumonia. Publishing original research, case reports, reviews, commentaries and correspondence, Pneumonia provides an international forum for the exchange of knowledge by scientists and clinicians involved in studying the etiology and pathogenesis of pneumonia, as well as its diagnosis, epidemiology, treatment and prevention. The journal's scope extends to research on lung infections and diagnosis, inflammation and immunity, microbial pathogenesis and viral-bacterial interactions.
Cutting-edge research, insightful reviews and dedication to the community make Pneumonia an essential resource for clinicians, researchers, respirologists and allied professionals involved with infectious diseasea.
Pneumonia archive
Pneumonia transferred to BioMed Central from Griffith University ePress in January 2016.
The archive of the journal has been transferred to a new platform and all articles previously published in the journal can be accessed here.
