| necrotizing fasciitis in patients with liver cirrhosis: predominance of monomicrobial gram-negative bacillary infections. | necrotizing fasciitis (nf), a rare but severe infection, usually occurs in individuals with underlying chronic illness, but its clinical presentation among cirrhotic patients is infrequently discussed. forty-two cirrhotic patients with 47 episodes of nf between 1995 and 2006 were analyzed. their mean age was 55.6 years, with male preponderance (34 patients, 81%). lower extremities were mainly involved (70%). of 42 episodes with identified pathogens, 41 (97%) were monomicrobial infections and wer ... | 2008 | 18653302 |
| structure of asce and induced burial regions in asce and ascg upon formation of the chaperone needle-subunit complex of type iii secretion system in aeromonas hydrophila. | in the type iii secretion system (t3ss) of aeromonas hydrophila, the putative needle complex subunit ascf requires both putative chaperones asce and ascg for formation of a ternary complex to avoid premature assembly. here we report the crystal structure of asce at 2.7 a resolution and the mapping of buried regions of asce, ascg, and ascf in the asceg and ascefg complexes using limited protease digestion. the dimeric asce is comprised of two helix-turn-helix monomers packed in an antiparallel fa ... | 2008 | 18662905 |
| sdia, an n-acylhomoserine lactone receptor, becomes active during the transit of salmonella enterica through the gastrointestinal tract of turtles. | luxr-type transcription factors are typically used by bacteria to determine the population density of their own species by detecting n-acylhomoserine lactones (ahls). however, while escherichia and salmonella encode a luxr-type ahl receptor, sdia, they cannot synthesize ahls. in vitro, it is known that sdia can detect ahls produced by other bacterial species. | 2008 | 18665275 |
