Molecular Characterization of Carbapenem-Resistant Acinetobacter baumannii Associated with Nosocomial Infection in the Pelotas, RS, Brazil.

Acinetobacter calcoaceticus-Acinetobacter baumannii complex (ACB) comprises some opportunistic pathogens associated with infectious outbreaks in hospital settings. A. baumannii is the most relevant species owing to its capacity to develop resistance to the different classes of antimicrobials.

LemA and Erp Y-like recombinant proteins from Leptospira interrogans protect hamsters from challenge using AddaVax™ as adjuvant.

Background: Recombinant subunit vaccines have been extensively evaluated as promising alternatives against leptospirosis. Here, we evaluated two proteins in formulations containing the adjuvant AddaVax™ as vaccine candidates for prevention and control of leptospirosis.

Methods: Recombinant proteins rErp Y-like and rLemA were characterized by ELISA to assess their ability to bind extracellular matrix (ECM) components and fibrinogen.

Identification of suitable adjuvant for vaccine formulation with the Neospora caninum antigen NcSRS2.

The parasite Neospora caninum is the main cause of abortion in cattle in many countries around the world, so a vaccine is a rational approach method for the control of the disease. An effective vaccine should be able to prevent both, the horizontal and vertical transmission of N. caninum.

Use of ELISA based on NcSRS2 of Neospora caninum expressed in Pichia pastoris for diagnosing neosporosis in sheep and dogs.

Neosporosis is a disease caused by the protozoon Neospora caninum that leads to significant economic losses in many countries. In the present study, we report on use of the recombinant protein NcSRS2 of N. caninum expressed in Pichia pastoris in an indirect immunoenzymatic assay (ELISA) for diagnosing neosporosis infection in sheep and dogs.
