Amplified Fragment Length Polymorphism (AFLP) profiling was used to evaluate the distribution of phenotypically indistinguishable, but genetically distinct, among Campylobacter concisus strains from South Africa. A Polymerase Chain Reaction (PCR) assay described for identifying strains belonging to Genomospecies 1 and 2 was applied in this study. Forty-seven C. concisus strains were studied in ...

1 Amplified fragment length polymorphism (AFLP) and microsatellites (simple sequence repeats; SSRs) are useful methods for studying genetic diversity of willow (Salix spp.). AFLP delivers a large number of data points from a single experiment and is a useful method for distinguishing between closely related individuals. SSR markers are very robust tools, and we have identified several markers t...

Amplified fragment length polymorphism (AFLP) analysis was used for genetic typing of 88 Campylobacter jejuni subsp. jejuni and 4 Campylobacter coli isolates. Restriction endonucleases HindIII and HhaI were used in combination with the selective PCR primers HindIII+A and HhaIII+A. Selectively amplified PCR products were separated in an ABI 310 genetic analyser. After normalization, pattern simi...

Genetic similarities between 13 samples belonging to nine reference biotypes and two field populations of Bemisia tabaci (Gennadius), one field population of B. medinae Gómez-Menor and another of B. afer Priesner & Hosny, were evaluated using amplified fragment length polymorphism (AFLP) markers. The results indicate that B. tabaci biotypes can be grouped together with a minimum similarity coef...

The spined soldier bug, Podisus maculiventris (Say), is an important biological control agent of agricultural and forest pests; and it preys on eggs and larvae of lepidopteran and coleopteran species. Genetic variability among field samples collected from Michigan, Mississippi, Missouri, Florida and established laboratory colonies was examined using Amplified Fragment Length Polymorphism-Polyme...
