Bio-templated CdSe nanoparticle synthesis in a cage shaped protein, Listeria-Dps, and their two dimensional ordered array self-assembly

We report here, for the first time, a biotemplated synthesis of uniform CdSe nanoparticle (4.1 +/- 0.5 nm) and a fabrication of two-dimensional CdSe nanoparticles (over one micrometre) with nanometric gaps by cage-like protein, Listeria-Dps.close141

Household Transmission of Streptococcus pneumoniae among Siblings with Acute Otitis Media

Nasopharyngeal transmission of Streptococcus pneumoniae was evaluated among 23 siblings with acute otitis media (AOM). Restriction fragment length polymorphism revealed that the nasopharyngeal strains were identical between siblings in 12 of 13 clusters of AOM experienced in 11 families. This study demonstrated person-to-person transmission of S. pneumoniae, especially drug-resistant strains, among siblings with AOM
