RNA fingerprinting by arbitrarily primed PCR can be used to detect and clone transcripts that are differentially expressed between cells that have been subject to different environments or developmental programs. The method also allows an estimate of the number of genes that are differentially expressed under various circumstances. When many experimental(More)
Genomic fingerprinting by arbitrarily primed PCR was used to analyze the genetic variability among 59 Trypanosoma brucei stocks representing the three T. brucei subspecies isolated from various hosts and different countries in Africa. 14 oligonucleotide primers revealed 355 polymorphic binary characters which were used for phenetic and phylogenetic analysis(More)
Trypanosoma cruzi is highly heterogeneous in terms of genetics and biological properties. To explore the diversity of T. cruzi, we focused our study on the T. cruzi Tc52 protein playing a critical immunosuppressive role during infection. Sequence variability and expression levels of this virulence factor were analysed in various strains. Among the 40 amino(More)
Arbitrarily primed PCR fingerprinting of RNA and differential display resolved on an acrylamide gel has been extensively used to detect differentially expressed RNAs. However, after a differentially amplified product is detected the next steps are labor-intensive: a small portion of the fingerprinting gel that contains the differentially amplified product(More)
A set of 26 Trypanosoma brucei stocks from various African countries, previously characterized by multilocus enzyme electrophoresis (MLEE) for 18 polymorphic loci, have been selected to be representative of the three T. brucei classic subspecies. The kinetoplast DNA minicircle variable regions from these stocks have been amplified using the polymerase chain(More)
Gram-negative bacteria were isolated from knots induced by Pseudomonas savastanoi in olive trees (Olea europaea L.). A total of nine endophytic bacterial strains were isolated, each from inside a different tree knot. Biochemical characterization indicated that all the strains belong to the family Enterobacteriaceae. Phylogenetic analyses of the 16S rRNA(More)
A method is presented in which the reduced complexity and non-stoichiometric amplification intrinsic to RNA arbitrarily primed PCR fingerprinting (RAP-PCR) is used to advantage to generate probes for differential screening of cDNA arrays. RAP-PCR fingerprints were converted to probes for human cDNA clones arrayed as Escherichia coli colonies on nylon(More)
Parasitic protozoa of the genus Leishmania are the causative agents of leishmaniasis. Survival and transmission of these parasites in their different hosts require membrane-bound or extracellular factors to interact with and modify their host environments. Over the last decade, several approaches have been applied to study all the extracellular proteins(More)
Efforts for the development of new therapeutics, essential for the control of leishmaniasis rely mainly on screening of potentially effective compounds in pathogen growth/multiplication assays, both in vitro and in vivo. Screenings designed to closely reflect the situation in vivo are currently labor-intensive and expensive, since they require intracellular(More)
