background: colorectal cancer is the third cause of cancer death in western countries. age, inadequate diet, obesity, inactivity and genetic changes are some of the risk factors of colorectal cancer. correlation of genetic diversity in homologous recombination repair system with cancer was evaluated in many recent studies. this study was done to investigate the correlation of t241m polymorphism...

Actinobacillus pleuropneumoniae is a causative agent of porcine pleuropneumonia that is one of the important bacterial diseases of the respiratory tract of pigs. The disease occurs worldwide and results in serious economic losses to the pig-rearing industry. In this review, new typing methods based on the antigenic and genetic diversity of a protective outer membrane lipoprotein (OmlA), that ha...

the aims of the present study were to propose apolymerase chain reaction-restriction fragment length polymorphismpcr-rflp genotyping method for the ay_376689:c.773c>t single nucleotide polymorphism snp of the equine prkag3 gene, related to muscle performance, as well as to characterize this snp and a second polymorphism, aawr_02017454:g.121684t>c of the spata1 gene, related to male fertility, i...

BACKGROUND Zoonotic cutaneous leishmaniasis (ZCL) is a polymorphic disease that may show various clinical manifestations. Although it is suggested that the genetic variability of the parasite is one of the factors influencing clinical manifestations of leishmaniasis, no data exists regarding genetic polymorphism of Leishmania major (L.major). This study investigates the determination of genetic...

Restriction fragment length polymorphism (RFLP) analysis and partial-genome DNA sequencing are commonly used to infer genetic relationships among pathogens. This study compares the application of both techniques to the analysis of 16 pseudorabies virus isolates collected during a 1989 outbreak. Genetic distances derived from RFLP and DNA sequence data were not significantly correlated with geog...

Major histocompatibility complex (MHC) represents an important genetic marker for manipulation to improve the health and productivity of cattle. It is closely associated with numerous disease susceptibilities and immune responses. Bovine MHC, also called bovine leukocyte antigen (BoLA), is considered as a suitable marker for genetic diversity studies. In cattle, most of the polymorphisms are lo...

Human cancer risk assessment using molecular genetic techniques is a rapidly emerging field. Many studies suggest that both inherited and acquired genetic predispositions play an important role in carcinogenesis. Cytochrome P450 (CYP) 2E1 is involved in the metabolic activation of N-nitrosamines and other low molecular weight compounds. A recently described genetic polymorphism of CYP2E1 [DraI ...

Forty-eight strains representing the eight recognized Rhizobium species, two new Phaseolus bean Rhizobium genomic species, Bradyrhizobium spp., Agrobacterium spp., and unclassified rhizobia from various host plants were examined by restriction fragment length polymorphism (RFLP) analysis of 16S rRNA genes amplified by polymerase chain reaction (PCR). Twenty-one composite genotypes were obtained...

Restriction fragment length polymorphism (RFLP) analysis of isolates of Cryptosporidium parvum has revealed two subgroups, termed H and C. The limited resolution of the RFLP method precludes an in-depth study of the genetic structure of C. parvum populations. Published C. parvum restriction polymorphisms lie within protein-coding regions known to be more homogeneous than noncoding sequences. To...

The construction of a restriction fragment length polymorphism (RFLP) linkage map is based on the estimation of recombination frequencies between genetic loci and on the determination of the linear order of loci in linkage groups. RFLP loci can be identified as segregations of singular or allelic DNA-restriction fragments. From crosses between heterozygous individuals several allele (fragment) ...
