aerobic bacterial oral flora of garter snakes: development of normal flora and pathogenic potential for snakes and humans.garter snakes that are used for scientific laboratory studies or kept as exotic pets often become ill and die early in captivity. they may also act as reservoirs of potential human pathogens or transmit infection to man. a total of 126 strains of aerobic and facultative bacteria, most potential human and snake pathogens, were isolated from 82 garter snake oropharyngeal cultures. coagulase-negative staphylococcus species were the most common species isolated. acinetobacter calcoaceticus var. anit ...19817240404
[nodular pulmonary opacities caused by a severe suppurative bronchitis and bronchiectases].a 67-year-old man with chronic obstructive pulmonary disease (copd) for many years and a heavy smoker was hospitalized because of increasing dyspnoea and moderately productive cough. his general condition was clearly impaired. he was markedly cyanotic, he had a barrel-shaped chest, and there were wheezing rhonchi throughout the lung. body temperature was 37.8 degrees c. he had mild ankle oedema. the preliminary diagnosis was exacerbation of the copd with global respiratory failure. tests: there ...19957607059
evaluation of an extended blood culture protocol to isolate fastidious organisms from patients with aids.recent reports of fastidious pathogens suggest the need for special blood cultures for immunocompromised patients. blood cultures from 45 human immunodeficiency virus (hiv)-infected patients with unexplained fever (> or = 38.0 degrees c) and cd4 counts of < 125 cells per mm3 were collected into a vacuum tube with sodium polyanetholsulfonate, an isolator tube, and bactec aerobic and anaerobic bottles. blood from the sodium polyanethosulfonate tube was inoculated into bactec 13a bottles, which wer ...19968880497
characteristics of alcohol dehydrogenases of certain aerobic bacteria representing human colonic flora.we have recently proposed the existence of a bacteriocolonic pathway for ethanol oxidation [i.e., ethanol is oxidized by alcohol dehydrogenases (adhs) of intestinal bacteria resulting in high intracolonic levels of reactive and toxic acetaldehyde]. the aim of this in vitro study was to characterize further adh activity of some aerobic bacteria, representing the normal human colonic flora. these bacteria were earlier shown to possess high cytosolic adh activities (escherichia coli ih 133369, kleb ...19979161610
[diclofenac-induced colitis complicated by klebsiella oxytoca infection].a 25-year-old man presented with abdominal pain and bloody diarrhea. colonoscopy showed hemorrhagic proctocolitis with superficial erosions. histology was consistent with the diagnosis of ulcerative colitis and biopsy cultures were negative. despite treatment with prednisolone (40 mg/day), his clinical condition deteriorated and he was referred to our institution. on repeated questioning, the patient reported self-medication with diclofenac (200 mg/day) for 6 weeks to treat tendinitis prior to t ...200111598543
a fatal case of necrotizing fasciitis due to bacterial translocation of klebsiella oxytoca.we report a 73-year-old man with hepatocellular cell carcinoma who had eruptions on and severe pain in the lower leg. within several hours, the patient's skin lesions had progressed markedly. magnetic resonance imaging findings were consistent with necrotizing fasciitis. klebsiella oxytoca was isolated from cultures of biopsy samples taken from the leg. the resulting dna fingerprint pattern revealed that the enteric bacterium was the same as that obtained from the biopsy samples taken from the l ...200818297453
antibacterial properties of fish mucus from channa punctatus and cirrhinus mrigala.extracts and preparations made from the animal origin were used extensively in folk and modern medicine for treating many human diseases. in the present study efforts have been made to find the antimicrobial effect of the mucus of two bottom dwelling fresh water fishes namely, channa punctatus and cirrhinus mrigala. fish mucus were tested against ten pathogenic bacteria such as escherichia coli, klebsiella oxytoca, klebsiella pneumoniae, lactobacillus vulgaris, proteus mirabilis, pseudomonas aer ...200818700685
role of tolc in klebsiella oxytoca resistance to antibiotics.the gram-negative human pathogen klebsiella oxytoca is often resistant to several antibiotics such as fluoroquinolones, erythromycin, tetracycline, chloramphenicol and others. the aim of this study was to look at the mechanisms leading to this resistance and particularly the role of tolc and efflux mechanisms in determining resistance.200919240073
phenotypic characterization of human pathogenic bacteria in fish from the coastal waters of south west cameroon: public health implications.increasing economic and recreational opportunities, attractive scenery and a perception of a better quality of life are luring people to the coast. unfortunately, these activities together with the commensurate increase in population in the area inevitably result in pollution of coastal waters with excessive microorganisms and other pollutants. microbial pollutants not only contaminate the coastal water but also aquatic food sources, thus posing a health risk to consumers. fish is a major source ...200919658320
usefulness of pcr melting profile method for genotyping analysis of klebsiella oxytoca isolates from patients of a single hospital unit.the development of rapid and simple typing methods is required in order to identify possible sources of human exposure to opportunistic pathogens. klebsiella spp. belongs to a group of bacteria that are opportunistic pathogens responsible for an increasing number of multiresistant infections in hospitals. recently, we showed the high genetic diversity of k. oxytoca using a large collection of strains isolated from the patients of several hospitals in poland over a 50-year period. our results sho ...200919899618
comparison of the efficacy of rose bengal and erythrosin in photodynamic therapy against enterobacteriaceae.the aim of this study was to evaluate the effects of the photosensitizers rose bengal and erythrosin combined with a light-emitting diode (led) on enterobacteriaceae. twelve enterobacteriaceae strains isolated from the oral cavities of patients undergoing prolonged antibiotic therapy, including three escherichia coli, three enterobacter cloacae, three klebsiella oxytoca and three klebsiella pneumoniae, were studied. an enterobacteriaceae suspension (10(6) cells/ml) was prepared from each clinica ...201020232222
complete nucleotide sequence of the incn plasmid pkox105 encoding vim-1, qnrs1 and shv-12 proteins in enterobacteriaceae from bolzano, italy compared with incn plasmids encoding kpc enzymes in the usa.we determined the complete nucleotide sequence of pkox105, a 54 641 bp plasmid from a klebsiella oxytoca strain that was isolated from a resident of a long-term-care facility in bolzano, italy.201020656680
advances in defining etiology and new therapeutic approaches in acute diarrhea.defining etiology of acute diarrhea is critical to disease therapy and prevention. in this review we look at recent developments in etiologic agents of acute diarrhea and advances in therapy and prevention of the illness. newly appreciated agents include enterotoxigenic bacteroides fragilis, klebsiella oxytoca and laribacter hongkongensis. atypical enteropathogenic e. coli (epec) strains lacking the gene for epithelial attachment appear to be more important as causes of diarrhea than traditional ...200717825422
safety evaluation of an alpha-cyclodextrin glycosyltranferase preparation.alpha-cyclodextrin glucosyltransferase (alpha-cgtase, ec 2.4.1.19) is an amylolytic enzyme used for the production of alpha-cyclodextrin (alpha-cd), a novel, soluble dietary fiber, from food-grade starch. the safety of an alpha-cgtase preparation obtained by batch fermentation from a recombinant strain of escherichia coli k12 harboring the alpha-cgtase gene from klebsiella oxytoca strain m5a1 was examined. in a 13-week subchronic toxicity study in rats, the administration by gavage of the alpha- ...200415265615
in vivo selection of a chromosomally encoded beta-lactamase variant conferring ceftazidime resistance in klebsiella oxytoca.klebsiella oxytoca clinical isolate a was recovered from the urine of a 55-year-old man with prostatic and urinary tract infections. this isolate displayed a beta-lactam resistance phenotype consistent with overproduction of a chromosomally encoded class a beta-lactamase and had decreased susceptibilities to all beta-lactams except ceftazidime, cephamycins, and carbapenems. four weeks after treatment with an antibiotic regimen that included ceftazidime, k. oxytoca isolate b, which had a high lev ...200314638475
adrenal hemorrhage associated with klebsiella oxytoca bacteremia.septic adrenal hemorrhage is classically caused by meningococcemia. an autopsied case is presented of a 45-year-old man with adrenal hemorrhage due to klebsiella oxytoca bacteremia following placement of a central venous catheter. he died 5 hours after developing disseminated intravascular coagulation (dic). the bacterial entry site may have been the catheter. the cause of death was considered to be pulmonary edema due to bacteremia rather than adrenal insufficiency due to hemorrhage. septic adr ...19989868968
