Proteus mirabilis, a common agent of nosocomially acquired and catheter-associated bacteriuria, can cause acute pyelonephritis. In ascending infections, bacteria colonize the bladder and ascend the ureters to the proximal tubules of the kidney. We postulate that Proteus species uses the HpmA hemolysin and urease to elicit tissue damage that allows entry of these bacteria into the kidney. To stu...
Experiment studied the protective effect of probiotics bacteria Lactobacillus acidophilus against urinary tract infections in laboratory mice caused by Proteus mirabilis, by the preparation of heat-killed bacteriaLactobacillusacidophilus. 31 animals were divided into three groups, the first group contained five animals not treated, the second group contained five animals treated with the Lactob...
O antigens of Proteus mirabilis and Proteus vulgaris strains isolated from patients with bacteremia.
During the period of 1971 to 1979, 172 Proteus mirabilis and 17 Proteus vulgaris strains were collected from blood cultures. Of these strains, 144 could be grouped into 25 O antigens. The most common antigens were O3, O23, O10, O30, and O24, which represented 46.1% of all strains. The O antigen distribution of strains isolated from blood cultures did not differ significantly from that of fecal ...
In Vivo, after administration of treatment, concentrations of antimicrobial agents will reduce to sub-inhibitory levels (sub-MIC) and may therefore affect the properties of target bacteria. The purpose of the present study was to investigate the in vitro effect of sub-minimum inhibitory concentrations (sub-MIC) of ampicillin, gentamicin and nalidixin acid on morphology, growth, ammonium produc...
results fifty isolates were positive on the screening test. among them, positive pcr reactions were identified in 35/221 and 12/77 isolates of e. coli and klebsiella spp., respectively, including 16 (34.0%) for cit only, 7 (14.8%) for dha only, and 24 (51.0%) for both dha and cit. no isolate was positive for fox or mox. no proteus organism was positive for ampc genes. conclusions currently, phe...
phytochemical screening, antioxidant and antibacterial activities of aqueous and methanolic crude extracts of commiphora kerstingii leaves were investigated. the antioxidant and antibacterial properties of different solvent extracts of commiphora kerstingii plant were scrutinized. the phytochemical screening of the various extracts was carried out using standard methods and the results revealed...
there is a growing interest in food industry to replace the synthetic chemicals by the natural products with bioactive properties from plant origin. the aim of this study was to determine the chemical composition of mentha pulegium essential oil and to characterize the antimicrobial activities of the essential oil. the essential oil of mentha pulegium was analyzed by gc-ms. the evaluation of th...
The pleomorphic swarming bacilli of the genus Proteus are common human gut commensal organisms but also the causative agents of recurrent urinary tract infections and bacteremia. We sequenced and assembled the 3.99-Mbp genome of Proteus mirabilis ATCC 7002 (accession no. JOVJ00000000) and the 3.97-Mbp genome of Proteus vulgaris ATCC 49132 (accession no. JPIX00000000), both of which are commonly...
Analysis by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy demonstrated that the O-specific polysaccharides of Proteus mirabilis PrK 42/57 and P. vulgaris PrK 43/57 are structurally similar to that of P. vulgaris PrK 44/57 and different from the polysaccharide of P. mirabilis PrK 41/57 studied earlier. The lipopolysaccharides of these strains were tested using enzyme immunosorbent ass...
