use of in vitro susceptibility and pathogen prevalence data to model the expected clinical success rates of tigecycline and other commonly used antimicrobials for empirical treatment of complicated skin and skin-structure infections.the overall expected coverage for tigecycline and selected antimicrobial regimens based upon prevailing susceptibility rates was evaluated for the empirical therapy of complicated skin and skin-structure infections (csssis). consecutive, non-duplicate bacterial isolates collected from 2000-2005 from patients with documented csssi in 57 medical centres located in the usa (38 centres), france (6 centres), germany (7 centres), italy (3 centres) and spain (3 centres) were used to evaluate the freque ...200717959359
newly delineated syndrome of congenital lipomatous overgrowth, vascular malformations, and epidermal nevi (clove syndrome) in seven patients.we present a series of seven patients who were previously diagnosed with proteus syndrome, but who do not meet published diagnostic criteria for this disorder and whose natural history is distinct from that of proteus syndrome. this newly recognized phenotype comprises progressive, complex, and mixed truncal vascular malformations, dysregulated adipose tissue, varying degrees of scoliosis, and enlarged bony structures without progressive bony overgrowth. we have named this condition congenital l ...200717963221
species interactions in mixed-community crystalline biofilms on urinary catheters.previous experimental investigations of the crystalline biofilms that colonize and block urinary catheters have focussed on their formation by pure cultures of proteus mirabilis. in the urine of patients undergoing long-term catheterization, p. mirabilis is commonly found in mixed communities with other urinary tract pathogens. little is known about the effect that the other species have on the rate at which p. mirabilis encrusts catheters. in the present study, a set of data on the nature of th ...200717965358
polyamines in bacteria: pleiotropic effects yet specific mechanisms.extensive data in a wide range of organisms point to the importance of polyamine homeostasis for growth. the two most common polyamines found in bacteria are putrescine and spermidine. the investigation of polyamine function in bacteria has revealed that they are involved in a number of functions other than growth, which include incorporation into the cell wall and biosynthesis of siderophores. they are also important in acid resistance and can act as a free radical ion scavenger. more recently ...200717966408

effect of natural preservatives on the growth of histamine producing bacteria.present study deals with the hampering of the growth of histamine producing bacteria (hpb), by using nacl and spices which are easily available and cheaper cost wise. for this experiment, four strains of hpb viz. vibrio parahaemolyticus, bacillus cereus, pseudomonas aeruginosa and proteus mirabilis were tested against 1 to 10% concentrations of nacl and 1 to 5% concentrations of natural preservatives (turmeric, ginger and garlic) in a basal medium. hpb showed different growth rates at different ...200717915763
cowden syndrome.cowden syndrome (cs), due to germline mutations of the pten tumor-suppressor gene, is an often overlooked cancer predisposition syndrome associated with an increased risk of breast, thyroid, and endometrial cancers, as well as benign manifestations. germline pten mutations also are associated with syndromes that have not been historically connected to an increase in risk for malignancy. these disorders include bannayan-riley-ruvalcaba syndrome (brrs), proteus syndrome (ps), and proteus-like synd ...200717920899

[phosphatase activity in amoeba proteus at ph 9.0].in the free-living amoeba amoeba proteus (strain b), after paag disk-electrophoresis of the homogenate supernatant, at using 1-naphthyl phosphate as a substrate and ph 9.0, three forms of phosphatase activity were revealed; they were arbitrarily called "fast", "intermediate", and "slow" phosphatases. the fast phosphatase has been established to be a fraction of lysosomal acid phosphatase that preserves some low activity at alkaline ph. the question as to which particular class the intermediate p ...200717933343
regulatory circuit based on autogenous activation-repression: roles of c-boxes and spacer sequences in control of the pvuii restriction-modification system.type ii restriction-modification (r-m) systems comprise a restriction endonuclease (rease) and a protective methyltransferase (mtase). after r-m genes enter a new cell, mtase must appear before rease or the chromosome will be cleaved. pvuii and some other r-m systems achieve this delay by cotranscribing the rease gene with the gene for an autogenous transcription activator (the controlling or 'c' protein c.pvuii). this study reveals, through in vivo titration, that c.pvuii is not only an activat ...200717933763

mannose-resistant proteus-like and p. mirabilis fimbriae have specific and additive roles in p. mirabilis urinary tract infections.proteus mirabilis is an important uropathogen that can cause complicated urinary tract infections (uti). it produces several types of fimbriae, including mannose-resistant proteus-like (mr/p) fimbriae and p. mirabilis fimbriae (pmf). previously, we determined that these fimbriae affect the ability of p. mirabilis to colonize the urinary tract. the objective of this study was to analyse the effect of the simultaneous lack of p. mirabilis mr/p and pmf fimbriae in uti pathogenesis. a double mutant ...200717854474
bacterial defluorination of 4-fluoroglutamic acid.fluorinated amino acids are used as enzyme inhibitors, mechanistic probes and in the production of pharmacologically active peptides. because enantiomerically pure 4-fluoroglutamate is difficult to prepare, the selective degradation of the l-isomer is a potentially convenient method of obtaining d-4-fluoroglutamate from the racemate. in this paper, we describe our investigations on the degradation of 4-fluoroglutamate by bacteria. fluoride ion was detected in resting-cell cultures of a number of ...200717901951
