dermatophytes are a group of keratinophilic fungi capable of invading keratinized tissues (skin, hair and nails). they cause dermatophytosis (commonly known as tinea or ring worm) in human and animals. in this report, dna similarities and genomic linkage of 40 dermatophytes strains was obtained from different universities, were studied by random amplified polymorphic dna (rapd–pcr) using 11 ran...

A cluster of bacteremia episodes with Klebsiella pneumoniae was noted in patients in a hematology-oncology ward during a 3-week period. Random amplified polymorphic DNA (RAPD) analysis, a novel technique for generating chromosomal fingerprints from bacterial isolates, was used as an aid to the epidemiological investigation of this cluster. For each of the two patients from whom multiple isolate...

Random amplified polymorphic DNA (RAPD) markers were successfully used in discrimination of sexes in Nile tilapia fish (Oreochromis niloticus) using linear discriminant function analysis. The results provide support for the view that major genetical sex determining factors exist in tilapia.

Differences were detected in the gene expression of strains of E. histolytica using RNA (RAP-PCR) and DNA fingerprinting (RAPD). Analysis of the electrophoretic profiles of the gels revealed some polymorphic markers that could be used in the individual characterization of the strains. The 260 bands generated by using five different primers for RAP-PCR, as well as RAPD, were employed in the cons...

Random amplified polymorphic DNA (RAPD) was used to study the genetic variations among strains from Fusarium sambucinum isolated from wheat in Upper Egypt. Using two different primer (V6 and M13), the used strains showed a high degree of similarities and a distinct RAPD patterns. The dendrogram that constructed based on M13 primers showed that, there is no correlation between isolation sources ...

Methods for identifying isolates of various pathogenic bacteria by DNA fingerprinting with random primers (RAPD) have been described recently. In these methods many primers are screened and the primers that generate the most informative DNA pattern are selected. A new strategy that simplifies the primer selection process for RAPD fingerprinting has been developed in our laboratory. In this appr...

The semaphore cactus in the Florida Keys bus until recently been considered a disjunct location of the Jamaican Opuntia spinosissima. Loss of all but one population in the Keys coupled with recent suggestions that the species should be taxonomically separated from the Jamaican cactus and is, therefore, a Florida Keys endemic, makes this population of conservation concern. Random amplified polym...

Fifteen well-defined strains of Aeromonas of thirteen species were analyzed by SDS protein electrophoretic analysis (SDS-PAGE) and random amplified polymorphic DNA analysis (RAPD). The comparison between the patterns obtained by both methods allowed differentiating all the strains. Clusters formed by the unweighted pair group method with arithmetic averages applied to protein data correlates wi...

in the present study, random amplified polymorphic dna (rapd) and inter-simple sequence repeat (issr) markers were used to estimate genetic diversity and relationships among 35 cluster bean [cyamopsis tetragonoloba (l.) taub] genotypes. for rapd analysis, 20 random primers were used which amplified 164 bands, 147 of which were polymorphic with an average polymorphism of 90.3%. the amplified pro...
