Crystal structures of penicillin-binding protein 6 from Escherichia coli.

12 Oct 2009 Penicillin-binding protein 6 (PBP6) is one of the two main DD-carboxypeptidases in Escherichia coli, which are implicated in maturation of bacterial cell wall and formation of cell shape. Here, we report the first X-ray crystal structures of PBP6, ... Read more...

Recruitment of antigen-specific CD8+ T cells in response to infection is markedly efficient.

2 Sep 2009 The magnitude of antigen-specific CD8+ T cell responses is not fixed but correlates with the severity of infection. Although by definition T cell response size is the product of both the capacity to recruit naïve T cells (clonal selection) and their ... Read more...

Leuconostoc spp sepsis in an extremely low birth weight infant: a case report and review of the literature.

30 Aug 2009 A three week old extremely low birth weight (ELBW) infant infected by vancomycin-resistant Leuconostoc spp is presented. Treatment with appropriate antibiotics was successful after the percutaneous inserted central catheter (PICC) was removed. The ... Read more...
