The failure of metronidazole treatment was observed in two patients infected with nim -negative Prevotella isolates, isolates LBN b Prevotella nanceiensis and LBN P. Enhanced pathogenicity of susceptible strains of the Bacteroides fragilis group subjected to low doses of metronidazole.
However, none of the known IS elements that have been associated with nim genes were detected upstream of nimI. Open in a separate window. Thus, the in vivo selection of a resistant subpopulation, which was responsible for treatment failure, was demonstrated and corroborated the previous observation that the initial isolate became resistant after prolonged in vitro exposure to metronidazole. In the present study, the review of the charts of patients with P.
Author information Article notes Copyright and License information Disclaimer. NimI was also recently detected in two other P. It is necessary to follow the general instructions.
Journal List Antimicrob Agents Chemother v. Metronidazole is commonly used for the treatment of infections caused by anaerobic organisms. Powered by ChronoForms – ChronoEngine.
Prevalence of antibiotic resistance in anaerobic bacteria: No plasmid was found in any of the P. Janse Van Rensburg, and L. Dissemination of nim -class genes, encoding nitroimidazole resistance, among different species of gram-negative anaerobic bacteria isolated in Athens, Greece.

These bacteria, which are part of the human oral, intestinal, and urogenital floras, may be involved in various infections, including infections of the head and neck, respiratory tract, central nervous system, and abdominal and urogenital tracts, as well as bacteremia Reduced susceptibility to 5-nitroimidazole drugs is generally associated with the presence of a nitroimidazole reductase encoded by a nim gene. This suggests that other potential resistance mechanisms may exist for these isolates, such as decreased pyruvate: Grollier4 and A.
National Center for Biotechnology InformationU. In the present study, metronidazole resistance could be selected after prolonged in vitro exposure to this drug in all nim -positive Prevotella strains tested. Strip of board — a sawn wooden product, thickness is more than 38 mm, width — 201-100 is more than 75 mm.
Vancomycin treatment failure associated with heterogeneous vancomycin-intermediate Staphylococcus aureus in a patient with endocarditis and in the rabbit model of endocarditis. Overexpression of the rhamnose catabolism regulatory protein, RhaR: It should not be used with wooden parts which wear out very quickly, for example, with a wooden floor.
Plastic container Quantity in a container: For the nimI -positive strains, no differences in the nim gene sequences were found in strains that converted from metronidazole susceptibility to metronidazole resistance. In conclusion, this study led to the description of a new nim gene which seems to be intrinsic to the species P.
Shipping cost For shipping cost calculation, write down your exact address and the quantity of the required product. The same nim gene was amplified from P. You should apply every layer very thoroughly.

Inducible metronidazole resistance and nim genes in clinical Bacteroides fragilis group isolates. This suggests that, as for other nim genes, the expression of nimI may be modulated by mechanisms other than those related to the presence of IS elements, although it cannot be ruled out that new IS elements that are not recognized by the primers used may be involved.
In the few studies examining the distribution of nim genes in Prevotella spp. Chromosomal localization of this single-copy gene was demonstrated in all clinical isolates as well as lb type strain P. This study is the first description of a new nitroimidazole resistance gene in P.
