The nosZ gene encodes nitrous oxide reductase, a key enzyme in the nitrous oxide reduction that occurs during complete denitrification. Many conventional approaches have used Proteobacteria-based primers to detect nosZ in environmental samples. However, these primers often fail to detect nosZ in non-Proteobacteria strains, including Firmicutes (Gram-positive) and Bacteroidetes. In this study, n...

When we consider factors that contribute to the emergence, amplification, and persistence of antibiotic resistant bacteria, the conventional assumption is that antibiotic use is the primary driver in these processes and that selection occurs primarily in the patient or animal. Evidence suggests that this may not always be the case. Experimental trials show that parenteral administration of a th...

background nucleic acid based detection of mycobacterium tuberculosis has the potential to improve the analysis of the tuberculosis epidemiology and patient care by increasing the specificity and sensitivity of diagnosis. patients and methods fifty suspected cases were screened for m. tuberculosis by using a new primer sequence and comparing its results with the primer (is6110) most widely used...

In this paper, first, an approximation formula for the amplification factor of surface soil is proposed. However, since most traditional houses are located on good condition, lower limit 1.23 may be acceptable in reality. On other hand, large sites hardly related to shaking area during Hanaore-fault-zone earthquake which deeply safety Kyoto. We also pointed out that increase bearing capacity de...

Azoarcus tolulyticus is a new class of widely distributed toluene-degrading denitrifiers of potential importance in remediating benzene, toluene, ethylbenzene, and xylene (BTEX)-contaminated environments. To detect these organisms in the environment, 16S rRNA gene-based phylogenetic probes were developed. Two sets of specific PCR amplification primers and two oligonucleotide hybridization probe...
