1 Introduction The first step of RAPD fingerprinting is the preparation of the target DNA template. Intuitively, minimal DNA template preparation should be necessary for RAPDs since, theoretically, PCR may amplify a single DNA molecule. It seems one would simply homogenize tissue and allow the PCR to "find" and amplify the target DNA. Indeed, many rapid DNA isolation methods designed for use wi...

DNA variation from randomly amplified polymorphic DNA (RAPD) (1, 2) has recently been helpful in addressing a wide range of evolutionary problems including the determination of paternity and maternity (3). It has been greeted with particular enthusiasm because it is fast, technically easy and requires little material (4). By using single 10 base primers of arbitrary sequences to amplify DNA wit...

Species-specific Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) markers were used to identify four species related to Anopheles (Nyssorhynchus) albitarsis Lynch-Arribàlzaga from 12 sites in Brazil and 4 in Venezuela. In a previous study (Wilkerson et al. 1995), which included sites in Paraguay and Argentina, these four species were designated "A", "B", "C" and "D". It was...

The study was under taken to identify Lactobacillus plantarum stains at molecular level by using PCR and RAPD. The genus and species specific PCR primers for Lactobacillus plantarum was used for the identification of the probiotic cultures. The randomly amplified polymorphic DNA (RAPD) technique was used to produce potential strain-specific markers to differentiate the two stains of L.plantarum...

In this study, we evaluated three PCR-based methods for the molecular typing of nonpathogenic Fusarium oxysporum isolates: random amplified polymorphic DNA (RAPD), polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and amplified fragment length polymorphism (AFLP). The analyses were performed using 64 isolates of F. oxysporum collected from cotton-producing areas in E...

Background: The present study represents a preliminary analysis of genetic diversity among Passiflora species using amplified genotypic data specific ITS and rbcL sequences non-specific RAPD-PCR markers for investigation the molecular phylogeny.
 Methods: PCR-RAPD uses ten primers polymorphic DNA, which are compiled on NTSYS software to construct dendrogram. gene used amplification from ge...

Poultry has long been cited as a reservoir for Campylobacter spp., and litter has been implicated as a vehicle in their transmission. Chicks were raised on litter removed from a broiler house positive for Campylobacter jejuni. Litter was removed from the house on days 0, 3, and 9 after birds were removed for slaughter. Chicks were raised on these three litters under controlled conditions in flo...

Escherichia coli is one of the most important bacterial avian pathogens and a common inhabitant of the gastrointestinal tract of animals. Most pathogenic E. coli can not be differentiated biochemically or by classic microbiologic methods. Molecular typing methods, particularly PCR, facilitated epidemiological and ecological studies of bacteria. Here we describe the application of a random ampli...

HIGHLIGHTS Hoopoe has been traditionally treated as a single species. RAPD PCR and COI gene barcodes were used to separate hoopoes. This study suggests the separation of Upupa epops major into new
