| studies on ternary metallo-beta lactamase-inhibitor complexes using electrospray ionization mass spectrometry. | metallo-beta-lactamases (mbls) are targets for medicinal chemistry as they mediate bacterial resistance to beta-lactam antibiotics. electrospray-ionization mass spectrometry (esi-ms) was used to study the inhibition by a set of mercaptocarboxylates of two representative mbls with different optimal metal stoichiometries for catalysis. bcii is a dizinc mbl (class b1), whilst the cpha mbl (class b2) exhibits highest activity with a single zinc ion in the active site. experimental parameters for the ... | 2006 | 16713713 |
| rabbit meat as a source of bacterial foodborne pathogens. | even though worldwide production of rabbit meat is >1,000,000 tons, little information is available for rabbit meat microbiology. this study provides data on the prevalence of salmonella, escherichia coli o157:h7, yersinia enterocolitica, listeria spp., motile aeromonas spp., and staphylococcus aureus on rabbit meat. a total of 24 rabbit carcasses from two abattoirs and 27 rabbit meat packages from supermarket displays were examined. in addition to culturing methods, associated virulence genes w ... | 2006 | 16715811 |
| genetic diversity among five t4-like bacteriophages. | bacteriophages are an important repository of genetic diversity. as one of the major constituents of terrestrial biomass, they exert profound effects on the earth's ecology and microbial evolution by mediating horizontal gene transfer between bacteria and controlling their growth. only limited genomic sequence data are currently available for phages but even this reveals an overwhelming diversity in their gene sequences and genomes. the contribution of the t4-like phages to this overall phage di ... | 2006 | 16716236 |

| b lymphocytes from early vertebrates have potent phagocytic and microbicidal abilities. | the present paradigm dictates that phagocytosis is accomplished mainly by 'professional' phagocytes (such as macrophages and monocytes), whereas b cells lack phagocytic capabilities. here we demonstrate that b cells from teleost fish have potent in vitro and in vivo phagocytic activities. particle uptake by b cells induced activation of 'downstream' degradative pathways, leading to 'phagolysosome' formation and intracellular killing of ingested microbes. those results indicate a previously unkno ... | 2006 | 16980980 |

| caspase-1 activation of lipid metabolic pathways in response to bacterial pore-forming toxins promotes cell survival. | many pathogenic organisms produce pore-forming toxins as virulence factors. target cells however mount a response to such membrane damage. here we show that toxin-induced membrane permeabilization leads to a decrease in cytoplasmic potassium, which promotes the formation of a multiprotein oligomeric innate immune complex, called the inflammasome, and the activation of caspase-1. further, we find that when rendered proteolytic in this context caspase-1 induces the activation of the central regula ... | 2006 | 16990137 |
