Identification of clinical isolates of Nocardia to the species level is important for defining the spectrum of disease produced by each species and for predicting antimicrobial susceptibility. We evaluated the usefulness of PCR amplification of a portion of the Nocardia 16S rRNA gene and subsequent restriction endonuclease analysis (REA) for species identification. Unique restriction fragment l...
We analyzed two single nucleotide polymorphisms (SNPs) of the IGF2 and CYP21 genes in Nellore cattle participating in the Brazilian Animal Breeding Program. The SNPs were found in exon 6 of the IGF2 (insulin-like growth factor 2) gene (RFLP/MboII) as well as in the promoter region of the CYP21 (steroid 21-hydroxylase) gene (RFLP/HpaII) of these animals. The TC heterozygotes were significant...
DNA fingerprinting techniques were used to type 273 isolates of Mycobacterium bovis from Australia, Canada, the Republic of Ireland, and Iran. The results of restriction fragment length polymorphism (RFLP) analysis with DNA probes from IS6110, the direct repeat (DR), and the polymorphic GC-rich sequence (PGRS) were compared with those of a new PCR-based method called spacer oligonucleotide typi...
Aim: Chital and sambar are the common wild small herbivores, which are vulnerable to poaching for their meat. Many times poachers claim the wild meat to be that of goat or sheep. Hence, authentic evidences are required to stop such wildlife crime. The present investigation was carried out to study the species specific PCR-RFLP patterns for meat identification of chital and sambar and then diffe...
OBJECTIVES To employ polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis for the rapid differentiation of Neisseria gonorrhoeae protein IB (PIB) isolates and to compare its usefulness with the widely accepted auxotype/serovar classification scheme. METHODS The outer membrane protein IB genes of 47 gonococcal isolates belonging to 10 different serovars ...
Molecular phylogeny and genetic diversity in all the nine species (Rhizophora mucronata, R. apiculata, R. stylosa, Bruguira cylindrical, B. parviflora, B. gymnorriza, Ceriops tagal and C. decandra) and a natural Rhizophora hybrid, of the mangrove Rhizophoraceae, occurring in the Indian sub-continent were analysed using random amplified polymorphic DNA (RAPD), restriction fragment length polymor...
Two hundred seventeen isolates of Borrelia burgdorferi originally cultured from skin biopsy samples or blood of early Lyme disease patients were genetically characterized by PCR-restriction fragment length polymorphism (RFLP) typing of the 16S-23S ribosomal DNA intergenic spacer. Three major RFLP types were observed. Of the cultured isolates, 63 of 217 (29.0%) were type 1, 85 of 217 (39.2%) wer...
objective(s):the utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease .the purpose of this study was to compare the genetic patterns of mycobacterium tuberculosis by three methods of rflp technique. materials and methods: in a cross-sectional and prospective study, 95 strains of ...
Our aim was to analyze the difference between methods for genotyping of Mycobacterium tuberculosis complex isolates. We collected genotyping results from Restriction Fragment Length Polymorphism (RFLP) and Mycobacterial Interspersed Repetitive Units-Variable Numbers of Tandem Repeat (MIRU-VNTR) in a geographically limited area (Stockholm) during a period of three years. The number and proportio...
