Application of specific primers and polymerase chain reaction for identification of ralstonia solanacearum biovar2

DETECTION OF BACTERIA BY AMPLIFYING THE 16S rRNA GENE WITH UNIVERSAL PRIMERS AND RFLP

Background: There is a conserved portion in the 16S rRNA gene of bacteria which can be amplified by the universal PCR method. This fragment is 996 bp in length. In this method, only one set of universal primers is used for the amplification of the conserved region of the 16S rRNA gene, in common bacterial pathogens. Therefore, using the universal PCR method, these bacteria are detectable on...

Identification of Casuarina-Frankia strains by use of polymerase chain reaction (PCR) with arbitrary primers.

Free-living N2-fixing Frankia strains isolated from Casuarina sp. were investigated for genomic polymorphism. We used six 10-mer oligonucleotides as single arbitrary primers (AP) for the polymerase chain reaction (PCR) in order to amplify random DNA fragments in the genome of free-living Frankia strains. Agarose-gels of the amplified genomic DNA revealed that two of the six arbitrary primers sh...

Characterization of superoxide dismutase Gram-positive bacteria by polymerase chain degenerate primers genes from reaction using

An internal fragment representing approximately 85% of sod genes from seven Gram-positive bacteria was amplified by using degenerate primers in a polymerase chain reaction assay. The DNA sequences of sod polymerase chain reaction products from Clostridium perfringens, Enterococcus faecalis, Enterococcus faecium, Lactococcus lactis, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus ...

Polymerase chain reaction assay targeting nox gene for rapid identification of Brachyspira canis in dogs

Genus Brachyspira,as Gram negative anaerobic bacteria, colonize in dogs intestine. The aim of the current study was to determine the prevalence of Brachyspira spp. for the first time in Iran and rapid identification of Brachyspira spp. in dogs by a new designment of a species-specific primer set for B. canis. One hundred fifty-one fecal samples were obtained ...
