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 ...200616927393
extended-spectrum beta-lactamases in taiwan: epidemiology, detection, treatment and infection control.extended-spectrum beta-lactamases (esbls) efficiently hydrolyze extended-spectrum beta-lactams such as cefotaxime, ceftriaxone, ceftazidime, and aztreonam. esbls are most often plasmid-mediated. in taiwan, the prevalence of esbls in bacteria has risen, ranging from 8.5 to 29.8% in klebsiella pneumoniae and 1.5 to 16.7% in escherichia coli isolates. the most prevalent types of esbls are shv-5, shv-12, ctx-m-3, and ctx-m-14 in isolates of k. pneumoniae and e. coli, with differences between institu ...200616926972
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.200616926463
fishmeal extract bile salt lactose agar--a differential medium for enteric bacteria.fishmeal extract bile salt lactose agar (febla), a new differential medium for enteric bacteria was developed and evaluated for its ability to grow and differentiate lactose fermenters (lf) from non-lactose fermenters (nlf) in comparison with macconkeys agar. performance of febla was at par with the latter. on febla medium, the contrast between lf and nlf colonies was pronounced and klebsiella pneumoniae produced more mucoid colonies than on macconkeys agar (hi media). unlike macconkeys agar, a ...200616924840
a comparison of antimicrobial susceptibility profile of urinary pathogens for the years, 1999 and 2003.urinary tract infection is a common condition worldwide; responsible for significant morbidity in both hospitalized and community patients. the laboratory records, for microbial isolates of infected urine and their susceptibility profiles for the years 1999 and 2003 were retrospectively reviewed and compared. in 2003, there was a significant decline in recovery ofcitrobacter spp compared to 1999. conversely, the proportion of k pneumoniae, e coli and enterococci increased dramatically in 2003, i ...200616921702

the challenges of proteus syndrome: diagnosis and management.proteus syndrome (ps) is a disorder of patchy or mosaic postnatal overgrowth of unknown etiology. the onset of overgrowth typically occurs in infancy and can involve any tissue of the body. commonly involved tissues include connective tissue and bone, skin, central nervous system, the eye, but it apparently can affect any tissue. diagnosing of ps is difficult and the diagnostic criteria are controversial. our group advocates stringent diagnostic criteria to facilitate research and appropriate cl ...200616883308
bacteria fauna from the house fly, musca domestica (l.).the house fly, musca domestica has long been considered a potential agent for disease transmission ever since its existence. the general truth of this assertion remains undisputed till the present day in spite of increasing awareness toward an improved sanitation and better hygiene. the habitual movement of house fly from filthy substrata such as human faeces, animal excreta, carcasses, garbage, etc. makes them ideal candidates for disease transmission such as cholera, shigellosis, salmonellosis ...200516883292
sterilisation of lucilia cuprina wiedemann maggots used in therapy of intractable wounds.three new techniques of sterilising maggots of lucilia cuprina for the purpose of debriding intractable wounds were studied. these techniques were utilisation of ultra-violet c (uvc) and maggot sterilisation with disinfectants. the status of sterility was checked on nutrient agar and blood agar and confirmed with staining. the indicators for the effectiveness of the methods were sterility and survival rate of the eggs or larvae. egg sterilisation with uvc had the lowest hatching rate (16+/-0.00% ...200516883286

[epidemiology and etiology of urinary tract infections in the community. antimicrobial susceptibility of the main pathogens and clinical significance of resistance].urinary tract infections (uti) are a frequent problem in primary care. they occur mainly in women without underlying diseases and with no functional or structural anomalies of the urinary tract; consequently most cases are considered uncomplicated uti. etiology is influenced by factors such as age, diabetes, spinal cord injury, urinary catheterization, and other factors. escherichia coli causes 80-85% of acute episodes of uncomplicated cystitis. staphylococcus saprophyticus, proteus mirabilis, s ...200516854352
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 ...200616842214
