Hepatozoon caimani in Caiman crocodilus yacare (Crocodylia, Alligatoridae) from North Pantanal, Brazil.

Hepatozoon species are the most common intracellular hemoparasite found in reptiles. Hepatozoon caimani, whose vectors are Culex mosquitoes, has been detected in a high prevalence among caimans in Brazil by blood smears examinations. The present work aimed to detect and characterize the Hepatozoon spp.

Floral ultrastructure of two Brazilian aquatic-epiphytic bladderworts: Utricularia cornigera Studnička and U. nelumbifolia Gardner (Lentibulariaceae).

Utricularia cornigera and Utricularia nelumbifolia are giant, aquatic-epiphytic species of carnivorous bladderwort from southeastern Brazil that grow in the central 'urns' of bromeliads. Both species have large, colourful flowers. The main aim of our study is to ascertain whether the prominent floral palate of U.

Microsatellite markers developed for Utricularia reniformis (Lentibulariaceae).

Premise Of The Study: Microsatellite markers were developed to study the genetic diversity and population structure of the carnivorous bladderwort Utricularia reniformis, which is endemic to the Atlantic Forest of southern and southeastern Brazil. Cross-species amplification was tested in U. gibba, U.

Phylogenetic relationships of Xylella fastidiosa strains based on 16S-23S rDNA sequences.

In spite of the lack of resolution of Xylella fastidiosa phylogenetic relationships, parsimony analysis of the 16S-23S rDNA sequence from a wide range of hosts has been evaluated in this research. In order to establish an easier method for sequencing the spacer region completely, a new primer pair was designed. The sequences obtained revealed a higher level of variation than that found in 16S gene sequences, with similarity values ranging from 0.
