Genetic diversity among toxigenic clostridia isolated from soil, water, meat and associated polluted sites in South India.

29 Sep 2009 PURPOSE: To investigate the genetic diversity of toxigenic Clostridium strains isolated from soil, water, meat and its associated polluted sites of Southern India. MATERIALS AND METHODS: A total of 27 identified isolates of six different toxigenic ... Read more...

Specific immuno capturing of the staphylococcal superantigen toxic-shock syndrome toxin-1 in plasma.

30 Aug 2009 Toxic-shock syndrome is primarily caused by the Toxic-shock syndrome toxin 1 (TSST-1), which is secreted by the Gram-positive bacterium Staphylococcus aureus. The toxin belongs to a family of superantigens (SAgs) which exhibit several shared ... Read more...

Protective antigen detection using horizontally stacked hexagonal ZnO platelets.

30 May 2009 Anthrax toxin detection before bacteremia, when toxin concentration is low, improves the chances of efficient treatment and cure. We present a novel technique for ultrasensitive detection of a protective antigen (PA(83)) of anthrax using an array of ... Read more...
