immune response of zebrafish (danio rerio) against a newly isolated bacterial pathogen aeromonas hydrophila.a strain of aeromonas hydrophila associated with unusual mortalities in zebrafish (danio rerio) culture facilities was isolated, identified and characterized. in challenge experiments, adult zebrafish were susceptible to infection by intraperitoneal (i.p.) injection with viable bacteria and its extracellular products (ecps) reaching very high mortalities in a few hours. the infection, by the viable bacteria or the ecps, caused cell death in kidney, due to the cytotoxic and haemolytic activities ...200818640853
abundance of sewage-pollution indicator and human pathogenic bacteria in a tropical estuarine complex.studies on abundance and types of various pollution indicator bacterial populations from tropical estuaries are rare. this study was aimed to estimate current levels of pollution indicator as well as many groups of human pathogenic bacteria and their seasonal variations in different locations in mandovi and zuari rivers in the central west coast of india. the sampling covered the estuarine and upstream regions of these rivers representing premonsoon (may 2005), monsoon (september 2006) and post- ...200918633722
therapeutic potential of two probiotics in inflammatory bowel disease as observed in the trinitrobenzene sulfonic acid model of colitis.the pathogenesis of inflammatory bowel disease is thought to be a multifactorial process. one of the leading hypotheses is that an imbalance in normal gut flora induces an excessive immune response and contributes to inflammation in the gastrointestinal tract. administration of probiotic bacteria reduces symptoms in patients suffering from inflammatory bowel diseases, probably via both manipulation of the microflora and stimulation of the intestinal immune system. in the current study the therap ...200818633675
major histocompatibility complex based resistance to a common bacterial pathogen of amphibians.given their well-developed systems of innate and adaptive immunity, global population declines of amphibians are particularly perplexing. to investigate the role of the major histocompatibility complex (mhc) in conferring pathogen resistance, we challenged xenopus laevis tadpoles bearing different combinations of four mhc haplotypes (f, g, j, and r) with the bacterial pathogen aeromonas hydrophila in two experiments. in the first, we exposed ff, fg, gg, gj, and jj tadpoles, obtained from breedin ...200818629002

identification of heme uptake genes in the fish pathogen aeromonas salmonicida subsp. salmonicida.aeromonas salmonicida subsp. salmonicida, the causative agent of furunculosis in fish, can use heme as the sole iron source. we applied the fur titration assay to isolate a cluster including six genes hutazxbcd that showed similarity to heme uptake genes of other gram-negative bacteria, and three genes orf123 of unknown function. the spatial organization of these nine genes, arranged in five transcriptional units, was similar to that of a homologous cluster in a. hydrophila. when a tonb system w ...200818535817
conformational changes in the metallo-beta-lactamase imis during the catalytic reaction: an epr spectrokinetic study of co(ii)-spin label interactions.metallo-beta-lactamases are responsible for conferring antibiotic resistance on certain pathogenic bacteria. in consequence, the search for inhibitors that may be useful in combating antibiotic resistance has fueled much study of the active sites of these enzymes. there exists circumstantial evidence that the binding of substrates and inhibitors to metallo-beta-lactamases may involve binding to the organic part of the molecule, in addition to or prior to binding to one or more active site metal ...200818528987
c1q-like inhibits p53-mediated apoptosis and controls normal hematopoiesis during zebrafish embryogenesis.except for the complement c1q, the immunological functions of other c1q family members have remained unclear. here we describe zebrafish c1q-like, whose transcription and translation display a uniform distribution in early embryos, and are restricted to mid-hind brain and eye in later embryos. in vitro studies showed that c1q-like could inhibit the apoptosis induced by actd and chx in epc cells, through repressing caspase 3/9 activities. moreover, its physiological roles were studied by morpholi ...200818514183
