a multi-center randomized trial to assess the efficacy of gatifloxacin versus ciprofloxacin for the treatment of shigellosis in vietnamese children.	the bacterial genus shigella is the leading cause of dysentery. there have been significant increases in the proportion of shigella isolated that demonstrate resistance to nalidixic acid. while nalidixic acid is no longer considered as a therapeutic agent for shigellosis, the fluoroquinolone ciprofloxacin is the current recommendation of the world health organization. resistance to nalidixic acid is a marker of reduced susceptibility to older generation fluoroquinolones, such as ciprofloxacin. w ...	2011	21829747
a multifactor regulatory circuit involving h-ns, virf and an antisense rna modulates transcription of the virulence gene icsa of shigella flexneri.	the icsa gene of shigella encodes a structural protein involved in colonization of the intestinal mucosa by bacteria. this gene is expressed upon invasion of the host and is controlled by a complex regulatory circuit involving the nucleoid protein h-ns, the arac-like transcriptional activator virf, and a 450ôçënt antisense rna (rnag) acting as transcriptional attenuator. we investigated on the interplay of these factors at the molecular level. dnase i footprints reveal that both h-ns and virf bi ...	2011	21724612
the rickettsia surface cell antigen 4 applies mimicry to bind to and activate vinculin.	pathogenic rickettsiae species cause high morbidity and mortality, especially r. prowazekii the causative agent of typhus. like many intracellular pathogens, rickettsiae exploit the cytoskeleton to enter and spread within the host cell. here we report that the cell surface antigen sca4 of rickettsiae colocalizes with vinculin in cells at sites of focal adhesions, and that sca4 binds to and activates vinculin through two vinculin binding sites (vbss) that are conserved across all rickettsia. rema ...	2011	21841197
epidemiology and molecular mechanism of integron-mediated antibiotic resistance in shigella.	integrons are gene capture and expression systems that are characterized by the presence of an integrase gene. this encodes an integrase, a recombined site, and a promoter. they are able to capture gene cassettes from the environment and incorporate them using site-specific recombination. the role of integrons and gene cassettes in the dissemination of multidrug resistance in gram-negative bacteria is significant. in shigella species, antimicrobial resistance is often associated with the presenc ...	2011	21842348

differential response of the human renal proximal tubular epithelial cell line hk-2 to shiga toxin types 1 and 2.	shiga toxins (stxs) are expressed by the enteric pathogens shigella dysenteriae serotype 1 and certain serotypes of escherichia coli. stx-producing bacteria cause bloody diarrhea with the potential to progress to acute renal failure. stxs are potent protein synthesis inhibitors and are the primary virulence factors responsible for renal damage that may follow diarrheal disease. we explored the use of the immortalized human proximal tubule epithelial cell line hk-2 as an in vitro model of stx-ind ...	2011	21708996
atomic structure of bacteriophage sf6 tail needle knob.	podoviridae are double-stranded dna bacteriophages that use short, non-contractile tails to adsorb to the host cell surface. within the tail apparatus of p22-like phages, a dedicated fiber known as the "tail needle" likely functions as a cell envelope-penetrating device to promote ejection of viral dna inside the host. in sf6, a p22-like phage that infects shigella flexneri, the tail needle presents a c-terminal globular knob. this knob, absent in phage p22 but shared in other members of the p22 ...	2011	21705802

the evolution of the escherichia coli phylogeny.	escherichia coli are familiar to biologists as a classical model system, ubiquitous in molecular biology laboratories around the world. outside of the laboratory, e. coli strains exist as an almost universal component of the lower-gut flora of humans and animals. although usually a commensal, e. coli has an alter ego as a pathogen, and is associated with diarrhoeal disease and extra-intestinal infections. the study of e. coli diversity predates the availability of molecular data, with strains in ...	2012	22266241
galectin 8 targets damaged vesicles for autophagy to defend cells against bacterial invasion.	autophagy defends the mammalian cytosol against bacterial infection. efficient pathogen engulfment is mediated by cargo-selecting autophagy adaptors that rely on unidentified pattern-recognition or danger receptors to label invading pathogens as autophagy cargo, typically by polyubiquitin coating. here we show in human cells that galectin 8 (also known as lgals8), a cytosolic lectin, is a danger receptor that restricts salmonella proliferation. galectin 8 monitors endosomal and lysosomal integri ...	2012	22246324
