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...

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...

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...

BACKGROUND Due to the differences in the oncogenic activity of human papillomaviruses (HPV), it is clinically important to accurately identify HPV types in a simple and time effective manner. OBJECTIVES We aimed at developing a straightforward and cost-effective assay to individually identify all mucosal HPVs, based on the amplification of L1 gene using MY09/11 primers, and subsequent restric...

AIM To develop polymerase chain reaction based artificial restriction fragment length polymorphism (artificial RFLP PCR) assays for DR3 and DR4 alleles of the multiallelic DRB1 locus and to apply them to paraffin wax embedded archival material. METHODS Sixty five samples from DRB1 typed cell lines were analysed using the artificial RFLP PCR method to determine the specificity and sensitivity ...

We compared genotyping by restriction fragment length polymorphism (RFLP) analysis of the amplified omp1 gene with serotyping by dot enzyme-linked immunosorbent assay (dot-ELISA) to determine the suitability of RFLP analysis for epidemiologic study. Fifteen prototypes of Chlamydia trachomatis and 30 clinical isolates were used in this study. To serotype with dot-ELISA, chlamydia antigen was spo...

Fusarium proliferatum is a well-known plant pathogenic fungus-infected many crops. The present study was carried out to molecularly identified and characterized morphologically F. from various hosts substrates. species identity of the isolates verified as based on TEF-1α sequences phylogenetic analysis indicated high intraspecific variations. RFLP-IGS also variations which were clustered into t...
