Fire retardant paint PROMADUR (Wooden structures)

These findings not only confirm that nim genes are not the only factors involved in the decreased susceptibility of Prevotella spp. Moreover, a phylogenetic tree based on Nim amino acid sequences showed that NimI formed a new homogeneous group distant from the other Nim types involved in metronidazole resistance in anaerobic bacteria data not shown.

Author information Article notes Copyright and License information Disclaimer. The paint PROMADUR is used in places where, according to the rules LBN there have to be wooden constructions according to EN to class of fire resistance Bs1, d0, and in places where there are requirements of fire resistance, for example, public buildings, homes, theaters, facilities for meetings, schools, etc.

Fire protection systems

It has been reported that the selection of microbial subpopulations that are resistant to the therapy administered may lead to the failure of treatment for infections caused by different bacterial species, including Prevotella spp. However, no conclusion can be 201-01 from this observation since that patient also received another active antibiotic.


For 021-10 calculation of the individual order or a discount, write in detail about the required sizes, parameters, quantity and additional accessories of the required product. The protein sequences were analyzed and aligned by using the BioEdit sequence alignment editor program http: The stability of the resistance was evaluated by determining the MIC of metronidazole after three consecutive subcultures on drug-free BBA.

The induced resistance was stable in all strains after subculture in the absence of metronidazole and also after 21-10 and freezing. Carpentier for technical assistance.

Published online Oct 5. In the present study, metronidazole resistance could be selected and remained stable in both the nim -positive and the nim -negative Prevotella strains tested, as well as in B.

Overexpression of the rhamnose catabolism regulatory protein, RhaR: No hybridization with any of the strains tested with the nimA gene probe was found. Inducible metronidazole resistance in nim -positive and nim -negative Bacteroides fragilis group strains after several passages on metronidazole containing Columbia agar plates.

Molecular investigation of genetic elements contributing to metronidazole resistance in Bacteroides strains. The predicted amino acid sequence alignment of NimI with homologs from other anaerobic bacteria showed that NimI formed a homogeneous group distinct from the other Nim types, with which NimI exhibited Clinical and Laboratory Standards Institute.

Metal tin Tin volume 5,0 kg Product number: Support Center Support Center. Shipping cost For shipping cost calculation, write down your exact address and the quantity of the required product.

Localization of nim genes. Selection and stability of metronidazole resistance. Moreover, we showed for the first time that subpopulations exhibiting high-level resistance to metronidazole can be selected from both silent nimI -positive and nim -negative Prevotella sp.


Metronidazole is commonly used for the treatment of infections caused by anaerobic organisms. Strips of board are usually used in loadbearing constructions, as well as columns. This article has been cited by other articles in PMC. Metronidazole resistance in Bacteroides spp. It should not be used with wooden parts which wear out very quickly, for example, with a wooden floor.

It is interesting to note that 16S rRNA gene sequencing was necessary to unambiguously identify all P. As it has previously been shown that metronidazole resistance may be detected only after prolonged incubation 91425a second reading of all tests was performed after an additional 72 h. PCR amplification with universal primers targeting the nim genes yielded products of about bp for seven clinical isolates. Carlier3 G. Mix well before application. That strain exhibited the same pulsed-field gel electrophoresis pattern as strain LBN after DNA digestion was performed by using XbaI data not shown.

For a long time, it has been considered that acquired resistance to this antibiotic is rare among anaerobes, despite its extensive use. Microbiology Pt 4: Chromosomal localization of this single-copy gene was demonstrated in all clinical isolates as well as in type strain P.
