Afin de comprendre l'épi­ démiologie de la dermatophilose, il est important de pouvoir différen­ cier entre les souches du germe. On a étudié vingt souches isolées sur le terrain à partir de bovins au Tchad et au Cameroun, ainsi qu'une souche américaine de référence, sur le polymorphisme des longueurs des fragments de restriction. Jun 28,  · L'approche moléculaire basée sur l'usage de l'amplification génique (RT-PCR) et l'analyse du polymorphisme des fragments de restriction (RFLP) a été utilisée pour la détection et le typage de trois isolats (Peerless, Texas et Khoukhi) du Prunus necrotic ringspot ilarvirus (PNRSV) sévissant dans les vergers et les parcs à bois d'amandier en Tunisie.

M ycoplasma hyopneumoniae is a globally prevalent swine respiratory pathogen of economic significance due to its impact on growth performance, feed efficiency, mortality, and associated preventive and therapeutic costs. There is evidence of genetic variation among M hyopneumoniae strains, but the biological significance of this variation in field situations is poorly understood. Two other Mycoplasma species are pathogenic to swine: Mycoplasma hyosynoviae, a cause of arthritis, and Mycoplasma hyorhinis, a cause of arthritis and fibrinous polyserositis. In contrast, Mycoplasma flocculare has been isolated from the respiratory tracts of swine 1 and is generally considered nonpathogenic.

Dr Adel Abuzenadah. Restriction Fragment Length Polymorphism (RFLP) Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their DNA. Polymorphisme de longueur des fragments de restriction de l’ADN (RFLP) La technique RFLP repose sur la digestion d'un DNA cible par une ou plusieurs enzymes de restriction spécifiques des sites de restriction portés par le DNA. A restriction fragment length polymorphism (RFLP) is defined by an enzyme, a restriction endonuclease, that cuts the doublestranded DNA at a particular sequence of bases, a probe, a labeled, complementary segment of DNA that will anneal to a portion of the digested sample, and a set of variable fragment length bands that appear on a Southern blot. Genotyping a biallelic RFLP marker in a family. One of the RFLP alleles lacks the restriction enzyme recognition site and manifests a single fragment (black in the family tree). The other allele harbours the restriction enzyme recognition site and displays two restriction fragments (white in the family tree). de restriction sont testées sur les ITS pour la longueurdes fragments de restriction; douze ontrévélé du polymorphisme.

Variabilité génétique des Poliovirus: étude du polymorphisme de la longueur des fragments de restriction enzymatique de souches isolées à Madagascar Article (PDF Available) · January Restriction fragment length polymorphism. In RFLP analysis, the DNA sample is broken into pieces (and digested) by restriction enzymes and the resulting restriction fragments are separated according to their lengths by gel electrophoresis. Although now largely obsolete due to the rise of inexpensive DNA sequencing technologies. adds restriction enzymes that cut the DNA at specific points. The resulting fragments can be sorted by length with gel electrophoresis technology to determine how many times a given VNTR is repeated. If two different samples show VNTRs of different lengths, the samples could not have come from the same person. On the other. Restriction fragment length polymorphism. Restriction fragment length polymorphisms (RFLPs) were developed by Botstein et al. (), which uses restriction enzymes that cut the DNA molecule at specific sites, called restriction sites, resulting in different fragments of variable lengths. Restriction Endonucleases Restriction endonucleases are enzymes that cleave DNA molecules at specific nucleotide sequences depending on the particular enzyme used. Enzyme recognition sites are usually 4 to 6 base pairs in length. Generally, the shorter the recognition sequence, the greater the number of fragments generated.

These accessions covered a large part of the geographical distribution areas of these species in America and Africa. Data were subjected to Factorial Analysis of Correspondence FAC and cluster analysis, with parameters of genetic diversity being also studied. In the E. Both markers revealed that genetic divergence between the two species is of the same magnitude as that among provenances of E. This finding is in discrepancy with the supposed early tertiary separation of the two species. Index terms: Elaeis oleifera , Elaeis guineensis , population genetics, palm species, genetic resources, molecular chacterization. Introduction Oil palm Elaeis guineensis is a crop widely cultivated in the humid tropics and represents one of the most important sources of vegetable oil. The history of oil palm breeding points to a narrow genetic base in the cultivated varieties. Presently, oil palm breeders are demanding for agronomic traits, such as disease resistance, oil fluidity, low growth rate and broad ecological adaptations, for which restricted genetic variability has been found on E. To broaden the oil palm genetic base, extensive germplasm collections were made in its natural range in Africa E. The wild American species E. The characterization of these genetic resources constitutes the first step to their effective utilization Simmonds, Molecular markers are supposedly free of environmental influence and readily detected at any stage in any part of the plant, through direct genome analysis. However, this technique requires a relatively large quantity of good quality DNA and the best results are obtained using radioisotopes, which makes RFLP technically and ecologically sensitive.
