emerging resistance to carbapenems in a tertiary care hospital in north india. | carbapenems are beta-lactam antibiotics, presently considered as most potent agents for treating multi-drug resistant gram-negative bacilli infections. in india carbapenems available for use are meropenem and imipenem, introduced recently. resistance to these has been reported in a few bacteria especially pseudomonas spp. we therefore retrospectively evaluated the antibiotic susceptibility pattern to these agents amongst various clinical isolates in a tertiary care hospital in north india. | 2006 | 16926463 |
characterisation of prototype nurmi cultures using culture-based microbiological techniques and pcr-dgge. | undefined nurmi-type cultures (ntcs) have been used successfully to prevent salmonella colonisation in poultry for decades. such cultures are derived from the caecal contents of specific-pathogen-free birds and are administered via drinking water or spray application onto eggs in the hatchery. these cultures consist of many non-culturable and obligately anaerobic bacteria. due to their undefined nature it is difficult to obtain approval from regulatory agencies to use these preparations as direc ... | 2006 | 16814892 |
1h nmr spectroscopy in the diagnosis of klebsiella pneumoniae-induced urinary tract infection. | the (1)h nmr spectroscopic method is suggested and its utility is demonstrated for the diagnosis of klebsiella pneumoniae (k. pneumoniae) in urinary tract infection (uti). k. pneumoniae have the specific property of metabolizing glycerol to 1,3-propanediol (1,3-pd), acetate, ethanol and succinate. the quantity of 1,3-pd produced correlates well with the viable bacterial count. other common bacteria causing uti (except for citrobacter frundii), such as escherichia coli (e. coli), pseudomonas aeru ... | 2006 | 16927393 |
pharmacokinetic and pharmacodynamic aspects of antimicrobial agents for the treatment of uncomplicated urinary tract infections. | uncomplicated urinary tract infections (uti) are treated with beta-lactams, co-trimoxazole, quinolones and fosfomycin tromethamine. due to increasing resistance of causative pathogens, antibiotics should be used by considering their pharmacodynamic and pharmacokinetic characteristics. beta-lactams have time-dependent activity and should not be used once-daily. co-trimoxazole should be restricted due to increasing chemoresistance. fluoroquinolones play a primary role in the treatment of serious a ... | 2006 | 16829051 |

the dps gene of symbiotic "candidatus legionella jeonii" in amoeba proteus responds to hydrogen peroxide and phagocytosis. | to survive in host cells, intracellular pathogens or symbiotic bacteria require protective mechanisms to overcome the oxidative stress generated by phagocytic activities of the host. by genomic library tagging, we cloned a dps (stands for dna-binding protein from starved cells) gene of the symbiotic "candidatus legionella jeonii" organism (called the x bacterium) (dps(x)) that grows in amoeba proteus. the gene encodes a 17-kda protein (pi 5.19) with 91% homology to dps and dna-binding ferritin-l ... | 2006 | 16950918 |
cysteine based novel noncompetitive inhibitors of urease(s)--distinctive inhibition susceptibility of microbial and plant ureases. | based on the catalysis mechanism of urease, a homologous series of 10 cysteine derivatives (cysds) was designed and synthesized, and their inhibitory activities were evaluated for microbial ureases (bacillus pasteurii, bpu, and proteus mirabilis, pmu) and for a plant urease [jack bean (cavavalia ensiformis), jbu]. as already described, thiol-compounds might inhibit urease activity by chelating the nickel atoms involved in the catalysis process. in contrast to cysteine, which has been reported to ... | 2006 | 16859909 |

the mechanism of plasmid curing in bacteria. | bacterial plasmids have a major impact on metabolic function. lactose fermentation of e. coli or hemolysin b transporter expressed by the plasmids that carry these respective genes could be readily obviated by heterocyclic compounds that readily bind to plasmid dna. these compounds could also reverse the resistance to antibiotics of e. coli, enterobacter, proteus, staphylococcus and yersinia strains by eliminating plasmids. however, the frequency and extent of this effect was significantly less ... | 2006 | 16842214 |

evolution and translation of research findings: from bench to where? | the credibility and replication of research findings evolve over time, as data accumulate. however, translation of postulated research promises to real-life biomedical applications is uncommon. in some fields of research, we may observe diminishing effects for the strength of research findings and rapid alternations of exaggerated claims and extreme contradictions--the "proteus phenomenon." while these phenomena are probably more prominent in the basic sciences, similar manifestations have been ... | 2006 | 17111044 |
