| [development of beta-lactamase resistance in enterobacteria]. | enterobacteria produce elementary chromosomal enzymes, beta-lactamases of class a: tem and shv (escherichia coli, klebsiella pneumoniae). these can give rise to plasmid-coded broad-spectrum beta-lactamases (esbl) discovered in 1980 (e. coli, k. pneumoniae, enterobacter cloacae). the first cefotaximase (ctx-m, men-1) was reported in europe in 1990. this enzyme is far more active against cefotaxime than against ceftazidime and aztreonam. chromosomal hyperpoduction of k1 beta-lactamase differs from ... | 2006 | 17051471 |
| animal models of inflammatory bowel disease: lessons from enteric infections. | mouse models of intestinal inflammation have played a key role in understanding the mechanisms that govern the inflammatory response in the intestine, and in designing new therapeutic strategies in the treatment of patients with inflammatory bowel disease (ibd). most of these models use chemical challenges, whereas relatively few robust models of intestinal inflammation caused by microbial infection are known. two common models of infectious murine colitis and typhlitis are infection with the mu ... | 2006 | 17057188 |
| role of lymphotoxins in the development of peyer's patches and mesenteric lymph nodes: relevance to intestinal inflammation and treatment. | hallmarks of the adaptive immune system are antigen-specific cellular and humoral immune responses. secondary lymphoid organs serve as sites of contact between antigen-presenting cells (apcs) and immune effector t and b lymphocytes. the gut-associated lymphatic system (galt) as the intestinal branch of the immune system provides different mechanisms to protect organisms against pathogens. simultaneously, immune activation secondary to genetic factors and/or environmental signals can induce detri ... | 2006 | 17057199 |

| colonic bacterial infection abrogates eosinophilic pulmonary disease. | induction of immunity to one pathogen in the lungs modifies the microenvironment and alters immunopathological changes that result from a second, unrelated pulmonary infection. however, it is unclear whether immunity generated at distant sites also affects lung immune responses. here, we show that infection with the gut-restricted bacterium citrobacter rodentium modifies immunopathological changes that result from pulmonary cryptococcus neoformans infection. th2 cytokine-driven pulmonary eosinop ... | 2006 | 16362886 |
| helminth-primed dendritic cells alter the host response to enteric bacterial infection. | to examine whether intestinal helminth infection may be a risk factor for enteric bacterial infection, a murine model was established using the intestinal helminth heligomosomoides polygyrus and a murine pathogen citrobacter rodentium, which causes infectious colitis. using this model we recently have shown that coinfection with the th2-inducing h. polygyrus and c. rodentium promotes bacterial-associated disease and colitis. in this study, we expand our previous observations and examine the hypo ... | 2006 | 16365440 |
| the lpf gene cluster for long polar fimbriae is not involved in adherence of enteropathogenic escherichia coli or virulence of citrobacter rodentium. | using the enteropathogenic escherichia coli (epec) genome sequence, we found that epec e2348/69 has an lpfabcde gene cluster homologous (about 60% identical at the protein level) to the salmonella long polar fimbria (lpf) operon. to determine whether this operon is essential for adherence, the lpfabcd(e2)(3) genes were deleted from epec strain e2348/69 by allelic exchange. analysis of the resulting epecdeltalpfabcd(e23) strain showed no change in adherence to hela cells or to human intestinal bi ... | 2006 | 16368980 |
| cd4+-t-cell effector functions and costimulatory requirements essential for surviving mucosal infection with citrobacter rodentium. | citrobacter rodentium causes an attaching and effacing infection of the mouse colon. surprisingly, protective adaptive immunity against this mucosal pathogen requires a systemic t-cell-dependent antibody response. to define cd4+ t-cell effector functions promoting this systemic defense of infected epithelial surfaces, studies were undertaken in weaning-age mice lacking costimulatory molecules cd28 or cd40l or cytokines gamma interferon (ifn-gamma) or interleukin-4 (il-4). adoptive transfer of cd ... | 2006 | 16369024 |
