campylobacter jejuni fatal sepsis in a patient with non-hodgkin's lymphoma: case report and literature review of a difficult diagnosis.campylobacter jejuni (c. jejuni) bacteremia is difficult to diagnose in individuals with hematological disorders undergoing chemotherapy. the cause can be attributed to the rarity of this infection, to the variable clinical presentation, and to the partial overlapping symptoms underlying the disease. here, we report a case of a fatal sepsis caused by c. jejuni in a 76-year-old caucasian man with non-hodgkin's lymphoma. after chemotherapeutic treatment, the patient experienced fever associated wi ...201627077849
tubo-ovarian abscess with endometrial cyst probably infected by campylobacter fetus: two cases.campylobacter fetus often causes systemic infection in immunocompromised or older patients, and prenatal infection, but campylobacter has rarely been reported as a cause of adnexitis in healthy young women. here we report two cases of endometriotic cysts infected by c. fetus for the first time. in case 1, a 28-year-old woman with a left adnexal cyst was hospitalized for left tubo-ovarian abscess and underwent left salpingo-oophorectomy. in case 2, a 22-year-old woman with a right adnexal cyst wa ...201627080623
rapid identification and multiple susceptibility testing of pathogens from positive-culture sterile body fluids by a combined maldi-tof mass spectrometry and vitek susceptibility system.infections of the bloodstream, central nervous system, peritoneum, joints, and other sterile areas are associated with high morbidity and sequelae risk. timely initiation of effective antimicrobial therapy is crucial to improving patient prognosis. however, standard final identification and antimicrobial susceptibility tests (asts) are reported 16-48 h after a positive alert. for a rapid, effective and low-cost diagnosis, we combined matrix-assisted laser desorption/ionization time of flight mas ...201627148212
clinical and epidemiological analysis of campylobacter fetus subsp. fetus infections in humans and comparative genetic analysis with strains isolated from cattle.campylobacter fetus subspecies fetus (cff) is an important pathogen for both cattle and humans. we performed a systematic epidemiological and clinical study of patients and evaluated the genetic relatedness of 17 human and 17 bovine cff isolates by using different genotyping methods. in addition, the serotype, the dissemination of the genomic island containing a type iv secretion system (t4ss) and resistance determinants for tetracycline and streptomycin were also evaluated.201627177684
evaluation of various campylobacter-specific quantitative pcr (qpcr) assays for detection and enumeration of campylobacteraceae in irrigation water and wastewater via a miniaturized most-probable-number-qpcr assay.campylobacter spp. are the leading cause of bacterial gastroenteritis worldwide, and water is increasingly seen as a risk factor in transmission. here we describe a most-probable-number (mpn)-quantitative pcr (qpcr) assay in which water samples are centrifuged and aliquoted into microtiter plates and the bacteria are enumerated by qpcr. we observed that commonly used campylobacter molecular assays produced vastly different detection rates. in irrigation water samples, detection rates varied depe ...201627235434

whole genome sequence analysis indicates recent diversification of mammal-associated campylobacter fetus and implicates a genetic factor associated with h2s production.campylobacter fetus (c. fetus) can cause disease in both humans and animals. c. fetus has been divided into three subspecies: c. fetus subsp. fetus (cff), c. fetus subsp. venerealis (cfv) and c. fetus subsp. testudinum (cft). subspecies identification of mammal-associated c. fetus strains is crucial in the control of bovine genital campylobacteriosis (bgc), a syndrome associated with cfv. the prescribed methods for subspecies identification of the cff and cfv isolates are: tolerance to 1 % glyci ...201627599479
point mutations in the major outer membrane protein drive hypervirulence of a rapidly expanding clone of campylobacter jejuni.infections due to clonal expansion of highly virulent bacterial strains are clear and present threats to human and animal health. association of genetic changes with disease is now a routine, but identification of causative mutations that enable disease remains difficult. campylobacter jejuni is an important zoonotic pathogen transmitted to humans mainly via the foodborne route. c. jejuni typically colonizes the gut, but a hypervirulent and rapidly expanding clone of c. jejuni recently emerged, ...201627601641
polyphosphate and associated enzymes as global regulators of stress response and virulence in campylobacter jejuni.campylobacter jejuni (c. jejuni), a gram-negative microaerophilic bacterium, is a predominant cause of bacterial foodborne gastroenteritis in humans worldwide. despite its importance as a major foodborne pathogen, our understanding of the molecular mechanisms underlying c. jejuni stress survival and pathogenesis is limited. inorganic polyphosphate (poly p) has been shown to play significant roles in bacterial resistance to stress and virulence in many pathogenic bacteria. c. jejuni contains the ...201627672264
