13. Estudo estrutural e ultraestrutural dos espermatozoides nas tribos Apini, Bombini, Euglossini e Meliponini (Hymenoptera: Apinae), com considerações filogeneticas
The term "spermiocladistics" express the use of structural and ultrastructural charcteristics to compose character matrices for phylogenetic studies. Such studies, carried out for different animais, including insects, have been shown to be consistent and useful, at least for higher taxa. Therefore, we proposed, in this thesis, to carry out a detailed ultrast

14. Biology of Azospirillum-Sugarcane Association: Enhancement of Nitrogenase Activity †
Azospirillum brasilense was reisolated from associations with callus tissue cultures of sugarcane and compared with stock cultures of the inoculated bacterium and related strains. Although the reisolate had a growth rate similar to stock cultures, it exhibited a severalfold increase in maximum specific activity of nitrogenase. The reisolate and the parent cu

16. Similarity between the 38-kilodalton lipoprotein of Treponema pallidum and the glucose/galactose-binding (MglB) protein of Escherichia coli.
The recent discovery that abundant and immunogenic lipoproteins constitute the integral membrane proteins of Treponema pallidum has prompted efforts to investigate their importance in the physiology and ultrastructure of the organism and in immune responses during infection. Earlier studies identified a 38-kDa lipoprotein of T. pallidum believed to be specif
