| genome dynamics of campylobacter jejuni in response to bacteriophage predation. | campylobacter jejuni is a leading cause of food-borne illness. although a natural reservoir of the pathogen is domestic poultry, the degree of genomic diversity exhibited by the species limits the application of epidemiological methods to trace specific infection sources. bacteriophage predation is a common burden placed upon c. jejuni populations in the avian gut, and we show that amongst c. jejuni that survive bacteriophage predation in broiler chickens are bacteriophage-resistant types that d ... | 2007 | 17722979 |
| discovery of insertion element iscfe1: a new tool for campylobacter fetus subspecies differentiation. | the species campylobacter fetus is divided into the subspecies c. fetus subsp. venerealis (cfv) and c. fetus subsp. fetus (cff). cfv is the causative agent of bovine genital campylobacteriosis, a highly contagious venereal disease that may lead to serious reproductive problems, including sterility and abortion. in contrast, cff can be isolated from the gastrointestinal tract of a wide range of host species, is associated with abortion in sheep and cattle, and can also be isolated from local and ... | 2007 | 17697006 |
| development of a real-time fluorescence resonance energy transfer pcr to detect arcobacter species. | a real-time pcr targeting the gyrase a subunit gene outside the quinolone resistance-determining region has been developed to detect arcobacter species. the species identification was done by probe hybridization and melting curve analysis, using fluorescence resonance energy transfer technology. discrimination between arcobacter species was straightforward, as the corresponding melting points showed significant differences with the characteristic melting temperatures of 63.5 degrees c, 58.4 degr ... | 2007 | 17652482 |
| a case of mitral endocarditis due to campylobacter fetus subsp. fetus. | this report describes a patient presenting mitral native endocarditis due to campylobacter fetus subsp. fetus, which was revealed by syncope and identified using 16s ribosomal rna gene sequencing. this gene sequencing method has become the preferred approach to identifying the new emerging pathogens when discrepancies exist between phenotypical tests. | 2007 | 17642532 |
| high content of proteins containing 21st and 22nd amino acids, selenocysteine and pyrrolysine, in a symbiotic deltaproteobacterium of gutless worm olavius algarvensis. | selenocysteine (sec) and pyrrolysine (pyl) are rare amino acids that are cotranslationally inserted into proteins and known as the 21st and 22nd amino acids in the genetic code. sec and pyl are encoded by uga and uag codons, respectively, which normally serve as stop signals. herein, we report on unusually large selenoproteomes and pyrroproteomes in a symbiont metagenomic dataset of a marine gutless worm, olavius algarvensis. we identified 99 selenoprotein genes that clustered into 30 families, ... | 2007 | 17626042 |
| multicenter study to evaluate bloodstream infection by helicobacter cinaedi in japan. | helicobacter cinaedi has being recognized as an important human pathogen which causes bloodstream infections. although the first case of bacteremia with this pathogen in japan was reported in 2003, the true prevalence of h. cinaedi as a pathogen of bloodstream infections in this country is not yet known. therefore, the aim of our study was to assess the incidence of bacteremia with h. cinaedi in japan. we conducted a prospective, multicenter analysis in 13 hospitals during 6 months in tokyo, jap ... | 2007 | 17596362 |
| [bacteremia due to campylobacter fetus isolated by conventional methods from an immunocompromised patient]. | the genus campylobacter includes gram-negative, motile, curved rods that can evidence characteristic morphologies. these microorganisms require low oxygen tension and an increased level of co2 for growing. a case of bacteremia due to campylobacter fetus in a patient with a previous diagnosis of breast cancer with metastases in dorso-lumbar column and acute promyelocytic leukemia (fab-m3 variant) is presented. the patient was admitted to our institution due to loss of consciousness and a 2 day--h ... | 2007 | 17585657 |
| c-reactive protein collaborates with plasma lectins to boost immune response against bacteria. | although human c-reactive protein (crp) becomes upregulated during septicemia, its role remains unclear, since purified crp showed no binding to many common pathogens. contrary to previous findings, we show that purified human crp (hcrp) binds to salmonella enterica, and that binding is enhanced in the presence of plasma factors. in the horseshoe crab, carcinoscorpius rotundicauda, crp is a major hemolymph protein. incubation of hemolymph with a range of bacteria resulted in crp binding to all t ... | 2007 | 17581635 |
| a cyclic amp receptor protein-regulated cell-cell communication system mediates expression of a feca homologue in stenotrophomonas maltophilia. | stenotrophomonas maltophilia wr-c possesses an rpf/diffusible signal factor (dsf) cell-cell communication system. it produces cis-delta2-11-methyl-dodecenoic acid, a dsf, and seven structural derivatives, which require rpff and rpfb for synthesis. acquisition of iron from the environment is important for bacterial growth as well as the expression of virulence genes. we identified a gene homologous to feca, which encodes a ferric citrate receptor that transports exogenous siderophore ferric citra ... | 2007 | 17574998 |
| infection of the thyroid gland caused by campylobacter fetus subsp. fetus. | we report what we consider to be the first case of an abscess of the thyroid gland due to campylobacter fetus subsp. fetus (c. fetus) in a patient suffering from hyperthyroidism. c. fetus is known as a rare and opportunistic pathogen in humans, causing a broad variety of systemic infections. acquisition by humans is thought to occur through contact with animals or animal products and to start as a gastro-intestinal colonization. the detection of c. fetus in stool is challenging, since culture ef ... | 2007 | 17547296 |
| development of experimental genetic tools for campylobacter fetus. | molecular analysis of the virulence mechanisms of the emerging pathogen campylobacter fetus has been hampered by the lack of genetic tools. we report the development and functional analysis of escherichia coli-campylobacter shuttle vectors that are appropriate for c. fetus. some vectors were constructed based on the known campylobacter coli plasmid pip1455 replicon, which confers a wide host range in campylobacter spp. versatility in directing gene expression was achieved by introducing a strong ... | 2007 | 17513579 |
| fatal relapse of a purulent pleurisy caused by campylobacter fetus subsp. fetus. | campylobacter fetus is associated with invasive disease, while other campylobacter species, such as c. coli and c. jejuni, are a common cause of bacterial diarrhea. bacteremia has been well described, but pleurisy remains very uncommon. we report the recurrent isolation of a c. fetus subsp. fetus strain during two episodes of pleural effusion with a fatal outcome. | 2007 | 17507518 |
