2. Reduced genetic variability within coding and non-coding regions of the echinococcus multilocularis genome
Echinococcus multilocularis, a vulpine intestinal tapeworm, is the causative agent of alveolar echinococosis in humans, one of the most severe and lethal parasitic infections in man. To date, there is very little knowledge about the genetical polymorphism of this parasite. To assess sequence polymorphism, we analysed a sample of 33 E. multilocularis isolates

3. Variable related to the Trypanosoma cruzi (Chagas, 1909) and to the Triatoma brasiliensis vector (Neiva, 1911) that intervenes in the host-parasite relations / Variáveis relacionadas ao Trypanosoma cruzi (Chagas, 1909) e ao vetor Triatoma brasiliensis (Neiva, 1911) que interferem na interação parasito-hospedeiro
Despite of the multiclonal structure and genetical variability of Trypanosoma cruzi (Chagas, 1909), several investigations using the eletrophoretic profiles (zymodeme) and molecular techniques were used to characterize subpopulations of this parasite, further defining two main distinct and distant phylogenetic lineages: T. cruzi (TcI and TcII). In the presen

4. GerminaÃÃo de sementes de soja armezenadas em bancos de germoplasma / Soybean seeds germination stored in genebanks.
The conservation of plant genetic resources in genebanks, mainly as seeds, has the purpose of preserving the genetic materials that could be useful to mankind, by using techniques that give as higher longevity as possible to those stored seeds. The genebanks are the main places to let the genetical resources needed available to get new cultivars and/or to br

8. The Genetical and Environmental Determination of Phally Polymorphism in the Freshwater Snail Bulinus Truncatus
In some species of self-fertile pulmonate snails, two sexual morphs co-occur in natural populations: regular individuals and aphallic individuals that cannot transmit sperm to other snails. Purely aphallic populations therefore reproduce obligatorily by selfing. Understanding the evolution of aphally and selfing in these snails requires a precise knowledge o

9. Patterns of Interallelic Divergence at the Rabbit B-Locus of the Immunoglobulin Light Chain Constant Region Are in Agreement with Population Genetical Evidence for Overdominant Selection
Population studies at the b-locus of the ``constant'' regions of the rabbit immunoglobulin K1 light chain (c(k1)) revealed patterns of gene diversity resembling those that mark the peculiar nature of the major histocompatibility complex, such as large number of alleles, high heterozygosity levels, consistent excess of heterozygous individuals and long allele
