Abstract: The present invention relates to synergistic immunogenic compositions for preventing whooping cough and infections caused by Streptococcus pneumoniae. Additionally, the compositions according to the present invention may protect against infections caused by other pathogenic agents by means of a synergistic combination of antigens thereof. In particular, the present invention provides synergistic immunogenic compositions that comprise at least one cell antigen of inactivated Bordetella pertussis and at least one protein antigen comprising one or more surface proteins A (PspA) of Streptococcus penumoniae or fragments thereof. The present invention further provides synergistic immunogenic compositions comprising at least one cell antigen of inactivated Bordetella pertussis, at least one protein antigen comprising one or more surface proteins A (PspA) of Streptococcus penumoniae or fragments thereof, and one or more diphtheria and/or tetanus toxins.

Abstract: The present invention presents a Kunitz-type recombinant inhibitor obtained from a gene cloned from a cDNA library of salivary glands of the Amblyomma cajennense, and the inhibitor named Amblyomin-X has molecular mass of 13,500 Da.

Abstract: The primary objective of the present invention is the development of new mutant forms of the Sm14 protein, for producing a greater production volume. The recombinant proteins here obtained were capable of providing protection against schistosome and fasciola infection. The level of protection of Sm14 recombinant proteins obtained in the present invention was similar to that reached in the parasite saline extract. The mutant proteins of the present invention have reached approximately 100% of renaturation after the heating at 80° C., different from wild forms of the Sm14 protein. Moreover, after storage for 2 months at 4° C., mutant proteins have shown smaller ?-structure loss than wild forms that have shown formation with random structure, as demonstrated by the circular dichroism analysis, indicating the success of mutations.

Abstract: This invention refers to the process for obtaining the recombinant prothrombin activating protease (rLopap) in monomeric form, the recombinant prothrombin activating protease (rLopap), as well as its amino acid sequence. In addition to that, this invention also refers to the use of this protease for depleting the blood fibrinogen, and serve as diagnosis kit for dysprothrombinemias. This invention describes the obtainence in recombinant form and the characterization of a prothrombin activator protease of 21 kDa, named rLopap (Lonomia obliqua prothrombin activator protease), with serineproteases characteristics however it shows sequence of conserved amino acids as in a lipocalin family. The protein presents pro-coagulating activity, depleting blood fibrinogen and prolonging the coagulation time of human blood/plasma. The obtainence of rLopap in its recombinant form and showing adequate activity for allowing clinical Pharmacology essays is presented in this invention.
