We evaluated the ability of randomly amplified polymorphic DNA (RAPD) to type citrinin-producing Penicillium citrinum (P. citrinum) strains recovered from the forest's air in northern Iran. A total of 12 P. citrinum strains (P1-P12) were characterised by citrinin production and random amplification of polymorphic DNA (RAPD) technique. All the strains produced citrinin with levels ranging from 1...

Ten isolates of Paracoccidioides brasiliensis were examined for differences in virulence in outbred mice intravenously inoculated with the fungus, associated with mycelial morphology, and genetic patterns measured by random amplified polymorphic DNA (RAPD). Virulence was evaluated by viable yeast cell recovery from lungs and demonstration of histopathologic lesions in different organs. The resu...

Karnal bunt of wheat, caused by Tilletia indica Mitra is an important disease prevalent in several countries. The pathogen due to its heterothallic nature shows high variability. In the present study, genetic relationships among ten isolates of T.indica collected from different locations of India and 15 monosporidial lines raised from these isolates were investigated by using 34 RAPD and 28 ISS...

The spore-forming bacterium Bacillus licheniformis is a common contaminant of milk and milk products. Strains of this species isolated from dairy products can be differentiated into three major groups, namely, G, F1, and F2, using random amplification of polymorphic DNA (RAPD) analysis; however, little is known about the genomic differences between these groups and the identity of the fragments...

Wine quality is determined by the particular yeast strains prevailing at various stages of fermentation. Therefore, ability to make an easy, fast, and unambiguous discrimination yeasts strain level great importance. Here, tandem repeat-tRNA (TRtRNA) method with 5GAC or ISSR-MB primer sets random amplified polymorphic DNA (RAPD) analysis (GTG)3, R5, RF2 oligonucleotides were tested on non-Saccha...

Genetic relationships among 24 genotypes of Hyophila involuta collected from five different natural populations Mount Abu (Rajasthan) is analysed using RAPD and SSR markers. Based on efficiency parameters calculated for each marker system such as polymorphic information content (RAPD = 0.34; 0.66), index 2.78; 2.62) resolving power 8.13; 2.23), the shows higher values some indices but microsate...

the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Campylobacter jejuni is one of the most common causes of bacterial diarrhea worldwide and is the primary bacterial cause of food-borne illness. Adherence to and invasion of epithelial cells are the most important pathogenic mechanisms of Campylobacter diarrhea. Molecular characterization of invasive and noninvasive Campylobacter isolates from children with diarrhea and symptom-free children was...

Members of the Thermococcales are anaerobic Archaea belonging to the kingdom Euryarchaea that are studied in many laboratories as model organisms for hyperthermophiles. We describe here a molecular analysis of 86 new Thermococcales isolates collected from six different chimneys of a single hydrothermal field located in the 13 degrees N 104 degrees W segment of the East Pacific ridge at a depth ...

beauveria bassiana (balsamo) vuillemin is an important natural regulator of insect populations. identification of a suitable molecular marker for detecting a virulent phenotype on a target pest would be useful in screening for effective isolates against the pest. nine isolates of b. bassiana were tested for their virulence to adults of tribolium castaneum (herbst) in laboratory bioassay with 1×...
