| amino acid substitutions in naturally occurring variants of ail result in altered invasion activity. | yersinia enterocolitica is the causative agent of a variety of gastrointestinal syndromes ranging from acute enteritis to mesenteric lymphadenitis. in addition, systemic infections resulting in high mortality rates can occur in elderly and immunocompromised patients. more than 50 serotypes of y. enterocolitica have been identified, but only a few of them commonly cause disease in otherwise healthy hosts. those serotypes that cause disease have been divided into two groups, american and non-ameri ... | 1992 | 1370953 |
| occurrence of aminoglycoside phosphotransferase subclass i and ii structural genes among enterobacteriaceae spp. isolated from meat samples. | 3'-aminoglycoside phosphotransferase [aph(3')] enzymes are a group responsible for resistance to the antibiotics kanamycin (km) and neomycin (nm) in bacteria. escherichia coli ect24, originally isolated from a meat sample, harboured an 83-kb conjugative r-plasmid (prpj24) that carries transferable resistance to km and nm. plasmid prpj24 was transferred by conjugation to enterobacter cloacae 94r, which was used as the source of plasmid dna in development of a probe for the km-resistance determina ... | 1990 | 1369284 |
| coupled reductive and oxidative degradation of 4-chloro-2-nitrophenol by a co-immobilized mixed culture system. | the restriction of oxygen transfer in ca-alginate beads used for the immobilization of microbial cells was applied to a coupled reductive and oxidative microbial degradation of the xenobiotic 4-chloro-2-nitrophenol (cnp). the conversion of cnp by enterobacter cloacae under anaerobic conditions led to the formation of 4-chloro-2-aminophenol (cap, 81%) and 4-chloro-2-acetaminophenol (caap, 16%) after 50 h incubation. cap, the main reduction product, was further degraded under aerobic conditions by ... | 1990 | 1366971 |
| a method for removal of toxic chromium using dialysis-sac cultures of a chromate-reducing strain of enterobacter cloacae. | a method for removal of toxic hexavalent chromium (chromate: cro2-4) was developed by use of dialysis-sac cultures of a chromate-reducing strain of enterobacter cloacae (ho1). e. cloacae strain ho1 cells were put in dialysis (semipermeable membrane) sacs, and the sacs were submerged in water containing toxic cro2-4. the dialysis sacs allowed cro2-4 to diffuse into the culture, and cro2-4 was reduced anaerobically in the dialysis sacs by the e. cloacae cells. because reduced chromium readily form ... | 1990 | 1366562 |
| [panophthalmitis as a nosocomial infection]. | the submitted paper deals with an epidemic of severe postoperative panophthalmitis, its development, course, causes and sequelae incl. epidemiological characteristics. the disease developed in four patients 40 hours after operation of cataract. despite treatment all four patients developed septicaemia and therefore the affected eyeballs were eviscerated. from smears of the conjunctival sac of the affected patients and from the contents of the eviscerated eyeball proteus mirabilis and enterobacte ... | 1991 | 1364655 |
| characterization of the chromosomal aac(6')-ic gene from serratia marcescens. | the dna sequence of the chromosomal aac(6')-ic gene from serratia marcescens, which had been previously cloned (h. m. champion, p. m. bennett, d. a. lewis, and d. s. reeves, j. antimicrob. chemother. 22:587-596, 1988) was determined. high-pressure liquid chromatographic analysis of extracts prepared from escherichia coli carrying the chromosomal aac(6')-ic gene on a plasmid confirmed the presence of 6'-n-acetyltransferase activity in this strain, which was suggested by the aminoglycoside resista ... | 1992 | 1354954 |
| rapid genotyping shows the absence of cross-contamination in enterobacter cloacae nosocomial infections. | restriction fragment length polymorphism analysis (rflp) of total dna and rdna regions was used for the epidemiological evaluation of 10 enterobacter cloacae nosocomial isolates obtained from nine patients in our hospital. five of these patients were hospitalized during overlapping periods, thus raising the question of cross-contamination. a single biochemical pattern and antibiotic susceptibility profile was observed for all isolates but one. in contrast, based on the results of total dna and r ... | 1992 | 1353097 |
| molecular analysis provides evidence for the endogenous origin of bacteremia and meningitis due to enterobacter cloacae in an infant. | we analyzed the restriction fragment length polymorphism (rflp) of total dna and of ribosomal dna regions (ribotyping) to document the occurrence of endogenous, systemic bacteremia and meningitis due to enterobacter cloacae in a newborn. five strains of e. cloacae were isolated from this newborn. three of these strains were recovered from stool at counts of 10(8), 10(9), and 10(9) organisms/g of feces, respectively; one strain was isolated from blood; and one strain was isolated from cerebrospin ... | 1992 | 1352150 |
| handwashing and disinfection of heavily contaminated hands--effective or ineffective? | hands are among the principal vehicles for transfer of nosocomial pathogens in hospitals. often, outbreaks of infection are thought to be caused by a lack of compliance with handwashing guidelines, rather than due to the inadequacy of the handwashing agents used. in this study the effectiveness of proper handwashing and the use of three different hand disinfectants: ethanol 70% (e), isopropanol 40% (i) and alcoholic chlorhexidine (70%) (ac) was compared using three volunteers whose fingertips we ... | 1992 | 1351497 |
| epidemiological role of arthropods detectable in health facilities. | a total of 161 arthropod specimens were collected from 55 sites in a health care facility during july and september 1990. of the 116 bacterial isolates obtained from their body surfaces 6% were from parasites (mosquitoes), 59% from eusynanthropic arthropods (tenebrionid beetles, flies, german cockroaches, wasps), 16% from hemisynanthropic arthropods (ants, spiders) and 19% from occasionally encountered insects (non-biting midges, moths, beetles). most (88%) of the isolated bacteria were gram-neg ... | 1992 | 1350604 |
| sepsis associated with transhepatic cholangiography. | a retrospective study was carried out of 74 elderly patients with obstructive jaundice undergoing percutaneous transhepatic cholangiography (ptc) and/or percutaneous biliary drainage (pbd) in order to assess the effect of prophylactic antibiotics on the incidence of fever and sepsis complicating these procedures. seventeen patients underwent ptc alone, while 57 had both ptc and pbd. fifty-three patients had either primary or metastatic malignancy. in the other patients with benign disease, chole ... | 1992 | 1348071 |
| retrospective 6-year study of enterobacter bacteraemia in a danish university hospital. | in order to study the epidemiology of invasive enterobacter infections, data from 53 consecutive cases of bacteraemia due to this organism were compared with data from 72 randomly selected cases of escherichia coli bacteraemia. the cases occurred among patients admitted to a danish university hospital over a 6-year period. forty-eight cases were due to enterobacter cloacae and five were due to ent. aerogenes. enterobacter bacteraemia was more often of nosocomial origin than e. coli bacteraemia a ... | 1992 | 1348068 |
| effects of azadirachtin on rhodnius prolixus: immunity and trypanosoma interaction. | the effects of azadirachtin, a tetranortriterpenoid from the neem tree azadirachta indica j., on both immunity and trypanosoma cruzi interaction within rhodnius prolixus and other triatomines, were presented. given through a blood meal, azadirachtin affected the immune reactivity as shown by a significant reduction in numbers of hemocytes and consequently nodule formation following challenge with enterobacter cloacae beta 12, reduction in ability to produce antibacterial activities in the hemoly ... | 1992 | 1342719 |
| in vitro antibacterial activities of ticarcillin alone and ticarcillin plus clavulanic acid against beta-lactamase producing and non-producing microorganisms. | a total of 818 clinical bacterial isolates were tested for the production of beta-lactamase by rapid chromogenic cephalosporin method and for the susceptibility to ticarcillin alone and in combination with clavulanic acid (2 micrograms/ml) by agar dilution method. these included 83 strains of methicillin-sensitive staphylococcus aureus (mssa), 31 of methicillin-resistant s. aureus (mrsa), 49 of neisseria gonorrhoeae, 58 of haemophilus influenzae, 112 of escherichia coli, 118 of klebsiella pneumo ... | 1992 | 1342000 |
| diffusion of beta-lactam antibiotics into proteoliposomes reconstituted with outer membranes of isogenic imipenem-susceptible and -resistant strains of enterobacter cloacae. | the influence of outer membrane (om) permeability on carbapenem susceptibility was studied in strains of enterobacter cloacae, a species in which carbapenem resistance depends upon the conjunction of overproduction of the chromosomal cephalosporinase and reduction of om permeability. relative trans-om diffusion rates were measured using the liposome swelling assay. proteoliposomes were reconstituted with om from the members of an isogenic set of e. cloacae strains, selected in vivo or in vitro, ... | 1992 | 1336033 |
| epidemiological survey of genes encoding aminoglycoside phosphotransferases aph (3') i and aph (3') ii using dna probes. | the epidemiological survey of aph (3') i and aph (3') ii genes, at a time when the specific antibiotic pressure was very low, was carried out by dna-dna hybridization. the sample included 334 aminoglycoside resistant gram-negative bacteria collected from patients of a general hospital. of these, 251 hybridized with the aph (3') i-probe and 19 with the aph (3') ii-probe but only 190 strains showed high resistance levels (cim greater than 64 micrograms/ml) for kanamycin, neomycin and paromomycin. ... | 1992 | 1328557 |
| comparative in vitro activity of sparfloxacin (at 4140, rp 64206--spfx) against 275 multiresistant clinical isolates. | the in-vitro activity of sparfloxacin was compared with that of pefloxacin, ofloxacin, ciprofloxacin, imipenem, ceftazidime, gentamicin and amikacin against 275 multiresistant nosocomial clinical isolates. they consisted of pseudomonas aeruginosa (37), enterobacter cloacae (42), acinetobacter anitratus (60), klebsiella pneumoniae (37) and staphylococcus sp (99). minimum inhibitory concentrations (mic90) and geometric mean mics for sparfloxacin were as follows (mg/l): p. aeruginosa 128-23.7, e. c ... | 1992 | 1328554 |
| diversity of aminoglycoside resistance in enterobacter cloacae in greece. | ninety enterobacter cloacae strains isolated from 12 greek hospitals were examined in terms of epidemiological types and resistance mechanisms. using o serotyping 69% of the strains were assigned to a specific serotype and overall 16 different serotypes were identified. the combination of serotyping, phagetyping and biotyping efficiently discriminated most of the strains, indicating that single epidemic strains were not prevalent, although serotypes 3, 7, and group ii predominated. eight represe ... | 1992 | 1327784 |
| plasmid profiles of acinetobacter and enterobacter species of hospital origin: restriction endonuclease analysis of plasmid dna and transformation of escherichia coli by r plasmids. | a total of 37 multi-resistant strains (20 acinetobacter calcoaceticus and 17 enterobacter cloacae) were isolated from patients of the intensive care units. all the isolates were examined for resistance to a battery of antimicrobial agents by the disk diffusion method. plasmid profiles and restriction endonuclease analysis of plasmid dna by ecor1 revealed the spread of one a. calcoaceticus and two e. cloacae endemic strains. transformation experiments on escherichia coli competent cells by three ... | 1992 | 1321240 |
| detergent-shock response in enteric bacteria. | our work on bacterial detergent resistance started with the realization that bacteria growing in a sink full of soap must be resistant to the detergents in that soap. we chose sodium dodecyl sulphate (sds) as a model detergent and decided to see how much sds the bacterium growing in the sink could tolerate. the research program thus initiated has shown that bacteria such as enterobacter cloacae can grow in up to 25% sds and that sds-shock proteins constitute c. 8% of the proteins synthesized by ... | 1992 | 1316532 |
| detection of ciprofloxacin resistance in gram-negative bacteria due to alterations in gyra. | two plasmids containing the cloned escherichia coli wild-type gyra gene were used to transform ciprofloxacin-resistant gram-negative clinical isolates to screen for dna gyrase a-mediated quinolone resistance. the results show that the technique is simple and applicable to a wide range of gram-negative species including e. coli, enterobacter cloacae, klebsiella aerogenes, morganella morganii, proteus mirabilis, pseudomonas aeruginosa, campylobacter jejuni and neisseria gonorrhoeae. the use of an ... | 1992 | 1310671 |
| exposure effects of netilmicin on enterobacter cloacae clinical isolates. | the effects of netilmicin exposure on two aminoglycoside (amg)-resistant and two amg-susceptible enterobacter cloacae isolates were studied. it was found that 1 h incubation of bacterial suspensions with netilmicin at 16 mg/l reduces the amounts of lipopolysaccharides present on the bacterial surface. also, netilmicin pretreatment increased both the susceptibility to normal human serum and the adhesion to human epithelial cells of all four e. cloacae strains examined. | 1992 | 1288965 |
| beta-lactamase expression and cross-resistance to beta-lactam antibiotics in a nosocomial population of enterobacter. | this study sought to quantitatively describe the spectrum of constitutive and inducible beta-lactamase activity present in a tertiary care center's population of enterobacter species. beta-lactamase activity in the absence and presence of 2 recognized beta-lactamase-inducing antibiotics, cefoxitin and imipenem, was measured. the enterobacter cloacae (n = 35) population was strikingly bimodal, expressing 'all-or-none' cross-resistance to beta-lactams (except imipenem) corresponding to the baselin ... | 1992 | 1286572 |
| endocarditis due to accidental penetrating foreign bodies. | a 15 year old boy had an eight month history of recurrent fever, malaise and poor appetite. chest roentgenogram revealed a foreign object overlying the right ventricle. multiple blood cultures grew enterobacter cloacae. the patients condition improved and blood cultures became negative following gentamicin and carbenicillin therapy. e. cloacae was isolated from the foreign body (a finishing nail) at surgery. antimicrobial therapy was continued for a total of 30 days, and the patient made an unev ... | 1976 | 1274992 |
| nationwide epidemic of septicemia caused by contaminated intravenous products. i. epidemiologic and clinical features. | between mid-1970 and april 1, 1971, enterobacter cloacae or e. agglomerans septicemia developed in 378 patients in 25 american hospitals while they were receiving intravenous products manufactured by one company. each of the hospitals noted a marked increase in the incidence of such septicemia during this period. enterobacter agglomerans (formerly designated erwinia, herbicola-lathyri group) was better known as a plant pathogen and had been a human blood pathogen only rarely in the past. septice ... | 1976 | 1274981 |
| relative morphological effects induced by cefoxitin and other beta-lactam antibiotics in vitro. | cefoxitin, a new semisynthetic cephamycin antibiotic, induced filament formation at subinhibitory concentrations with a beta-lactamaseless strain of enterobacter cloacae (hsc 18410 m66). the extent of filament induction by cefoxitin was similar to that seen with cephalothin, cefazolin, and benzylpenicillin. filament induction by cefoxitin was markedly less than that seen with cephalexin, carbenicillin, ticarcillin, cephradine, and cephapirin. antibiotics which failed to induce filaments at any l ... | 1976 | 1267431 |
