The patient was treated with oxytetracycline and metronidazole (there was no history of recent use of either ampicillin or augmentin). The infected ulcer improved and six days later the Enterobacter cloacae could no longer be isolated. The strain was sensitive in vitro to tetracycline. This case shows that an augmentinresistant organism can be sensitive to ampicillin. Isolates should therefore ...

An outbreak of Enterobacter cloacae in the neonatal intensive care unit of a provincial hospital in Gauteng, South Africa, resulting in nine deaths was investigated. Macrorestriction analysis using pulsed-field gel electrophoresis revealed that three isolates of E. cloacae from blood cultures of patients, six from environmental sources, and one from the hands of a staff member belonged to the s...

in recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. the presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. the coal mine area in bokaro is one of the “toxic hotspot” in india. bacteria have evolved uptake and efflux mec...

Background Enterobacter cloacae bacterium is a known symbiont of the most Anopheles gut microflora and nominated as a good candidate for paratransgenic control of malaria. However, the population dynamics of this bacterium within An. stephensi and its introduction methods to the mosquitoes have not yet been explored. Methods Enterobacter cloacae subsp. dissolvens expressing green fluorescent ...

Washed cells of Enterobacter cloacae HO1 reduced hexavalent chromium (chromate: CrO4(2-) anaerobically. Chromate reductase activity was preferentially associated with the membrane fraction of the cells. Right-side-out membrane vesicles prepared from E. cloacae cells showed high chromate reductase activities when ascorbate-reduced phenazine methosulfate was added as an electron donor.

Enterobacter cloacae strain 96-3 nitroreductase (NR) is a homodimeric flavoenzyme that catalyzes the pyridine nucleotide-dependent four-electron reduction of a variety of nitroaromatic compounds, including the explosives TNT (2,4,6-trinitrotoluene), RDX (1,3,5-trinitro-1,3,5-triazine), tetryl (2,4,6-trinitrophenyl-N-methylnitramine), and pentryl (2,4,6-trinitrophenyl-N-nitroaminoethylnitrate). ...

Enterobacter aerogenes and E. cloacae have been reported as important opportunistic and multiresistant bacterial pathogens for humans during the last three decades in hospital wards. These Gram-negative bacteria have been largely described during several outbreaks of hospital-acquired infections in Europe and particularly in France. The dissemination of Enterobacter sp. is associated with the p...

Coliform tests were performed on 85 hide and 75 meat samples. IMViC reactions were determined on isolates from positive confirmed and fecal tests, and strains other than Escherichia coli were identified. Strains typed as Aerobacter aerogenes types I and II were identified as Enterobacter cloacae (51.4%), Klebsiella pneumoniae (21.5%), Enterobacter aerogenes (15%), and Enterobacter liquefaciens,...

AmpC regulatory genes in 21 ceftazidime-resistant clinical isolates of Enterobacter cloacae (MICs of > or = 16 microg/ml) were characterized. All isolates exhibited AmpC overproduction due to AmpD mutation. Additionally, we found two AmpR mutants among the isolates. This is the first report of chromosomal ampR mutation in clinical isolates of E. cloacae.
