Bovine Immunodeficiency Virus: Immunochemical Characterization and Serological Survey

Serological survey for bovine immunodeficiency virus in dairy cattle from Poland.

A seroprevalence study of bovine immunodeficiency virus (BIV) was undertaken on 1,541 serum samples from Holstein cattle from 23 herds, located in different geographical regions of Poland. The analysis was performed using ELISA, with recombinant Gag protein of BIV as antigen. The average BIV prevalence was 4.9% in individual cattle, while the percentage of herds harboring at least one seroposit...

Serological and genomic detection of bovine leukemia virus in human and cattle samples

Bovine leukemia virus (BLV) is a retrovirus responsible for lymphoproliferative disorders in cattle. Although infections of BLV in animals are well known, little is known about its capacity to infect humans. This study investigated the presence of anti-BLV antibodies and BLV proviruses in human and cattle samples. An indirect enzyme-linked immunosorbent assay (ELISA) was used to detect anti-BL...

Immunochemical characterization of antigens with serological cross-reactivity in trypanosomes

Trypanosomatidae is a group of protozoa belonging to Trypanosomatida order, where the genres of medical importance Leishmania and Trypanosoma are inserted. These genres include parasites Leishmania spp., Trypanosoma cruzi and Trypanosoma brucei, etiologic agents of leishmaniasis, Chagas disease and sleeping sickness, respectively classified as Neglected Tropical Diseases (NTDs) by the World Hea...
