Effects of cell-free supernatant of LA5 and 431 against planktonic form and biofilm of .

This study was carried out to investigate the stability, antibacterial properties and biofilm removal potential of cell-free supernatant (CFS) of LA5 and 431 against ATCC 25923. Antibacterial activity of both strains was measured according to the agar spot method. The CFS was prepared by centrifugation of bacterial suspension at 4000 for 10 min and the antimicrobial activity was measured usin...

The latitudinal gradient in rock-inhabiting bacterial community compositions in Victoria Land, Antarctica.

The harsh conditions in Victoria Land, Antarctica have formed a simple ecosystem dominated by microbes that use rocks as shelters to avoid environmental stressors. The area is composed of basement rocks that illustrate the history of complex deformation, thus it is highly valuable not only in perspectives of geology but also in biological aspects. Because this region is inhospitable to higher-leve...

CbpM and CbpG of Streptococcus Pneumoniae Elicit a High Protection in Mice Challenged with a Serotype 19F Pneumococcus.

Among many pneumococcal antigens, choline-binding proteins (CPBs) display a high immunogenicity in animal models. This study aims to determine the imm...
