| Anti-Babesia rodhaini monoclonal antibodies (mAb), namely: 1-E7, 2-H2 and 3-B8, significantly suppressed the development of high parasitemia in BALB/c mice infected with B. rodhaini and all mAb-treated mice survived the infection. While, only monoclonal antibody 3-B8 showed some inhibitory effect against Babesia microti, with mice showing high parasitemia of 18.04 ± 2.69 %, at 9 days post-exposure. Westernblot analysis of B. rodhaini and B. microti parasite extract reacted with anti-B. rodhaini monoclonal antibodies showed cross-reactive bands of molecular weights 62 and 55 kilodaltons. Comparison of the antigenic components of B. rodhaini and B. microti using polyspecific sera revealed several shared or common parasite antigens of molecular weights 62,... |

| Abstract Background Snakes of the genus Bothrops, popularly known as pit vipers, are responsible for most cases of snakebite in Brazil. Within this genus, Bothrops jararacussu and B. jararaca deserve special attention due to the severity of their bites and for inhabiting densely populated areas. Regarding the treatment of snakebites by Bothrops jararacussu, questions have been raised about the effectiveness of the specific bothropic antivenom in neutralizing myotoxic effects; however, there are no accurate data for humans. Thus, the development of a differential diagnostic kit for this species would be of great interest because it provides, for healthcare professionals, a tool that would allow us to determine whether the accident was caused by B.... |

| Abstract Human adenoviruses comprise an important group of etiologic agents that are responsible for various diseases in adults and children, such as respiratory, ocular, gastroenteric, and urinary infections. In immunocompromised and organ-transplanted individuals, these agents can cause generalized infections. Rapid diagnostic methods for detecting these infectious agents are not widely available.The aim of this work was to produce monoclonal and polyclonal anti-adenovirus antibodies to be used in a rapid diagnostic test for respiratory infections.Adenovirus hexons were satisfactorily purified by ultracentrifugation and chromatography. After virus purification, anti-hexon monoclonal antibodies were produced and characterized, following classical methods.... |

| Two hybridomas secreting monoclonal antibodies (MAbs) that react with a lipoprotein (LipL32) of the outer membrane of pathogenic Leptospira were obtained. For hybridoma production, spleen cells from BALB/c mice imunized with recombinant LipL32 (rLipL32) were fused to SP2/O-Ag14 cells, selected in HAT medium and screened in an indirect ELISA. One MAb produced was of the IgG2b isotype and the other was an IgM. MAbs specificity was confirmed by indirect ELISA and immunoblotting using purified rLipL32 and whole-cell antigen preparations from Escherichia coli (E. coli) expressing LipL32 and from pathogenic and non-pathogenic serovars. Both Mabs reacted with most of the pathogenic serovars tested and none reacted with non-pathogenic Leptospira. The MAbs... |

| The protozoan Bonamia ostreae (Ascetospora), a paasite of the flat oyster Ostrea edulis, was purified by differential and isopycnic centrifugations. Mice of the strain Balb/c were immunized with purified parasites and hybridomas were prepared by fusion of immunized mouse splenocytes with the mouse myeloma cell line P3-X63-Ag8-653. From the fusion, 12 clones were isolated and saved. The resulting antibodies were characterized with a solid phase radioimmunoassay (RIA). Antibodies from 7 clones reacted only with B. ostreae and not with normal host tissue. Although some of the antibiodies identified. One of these antibodies (20B2-1B12) has an apparent association constant of ca 3 X 10(8) M-1 and bound to a number of different sites on the parasite. These... |

| Digestive glands of mussels Mytilus edulis from Brittany, France, infected with Marteilia sp. (Ascetospora) were used to purify the parasite. A modification of a previously used purification protocol increased purification efficiency, permitting sporangial primordia and sporangia of Marteilia sp. to be obtained. Mouse (Balb/c) monoclonal antibodies were generated against this parasite. From the fusion, 26 monoclonal antibodies against Marteilia sp. were obtained. Antibodies from 6 clones reacted only with Marteilia sp. cells and not with normal host tissues. Four of these antibodies (1/1-3, 3/1-1, 4/1-1 and 6/2-3) reacted with the sporangia wall and two with the spore cytoplasm (9/1-1 and 12/5-1). Antibodies cross-reacted with Marteilia refringens from... |

| A battery of monoclonal antibodies were produced in mice against Theileria annulata-infected cells. Two of these antibodies (IgM and IgG1) reacted specifically with the surface membrane of the infected cells but not with Con A-stimulated or unstimulated bovine peripheral blood lymphocytes (PBL). The antibodies could stain also clones which were derived from the cell lines tested in the present study. Similarly, they reacted with T.annulata-infected but not with uninfected sheep PBL. After removal of the parasites by treating the infected cells with the anti-theilerial drug buparvaquone, the antibodies were no more able to bind to the cells. |

| A panel of 13 monoclonal antibodies (MAbs) that react against outer membrane proteins of Salmonella Enteritidis was obtained. Two MAbs were classified as IgM, six were IgG2a, three were IgG3 and one was of the IgG2b isotype. The reactivity of the MAbs against different serovars of Salmonella enterica and other bacteria was investigated using an indirect ELISA. Five MAbs reacted only against Salmonella Enteritidis. Two MAbs presented crossed reactions with thermo-extracted antigens of Klebsiella pneumoniae, Citrobacter freundii and Enterobacter aerogenes. MAb 424H presented wide spectrum of reactivity, detecting antigens of Salmonella belonging to serogroups B, C, D, E and G. The detection limit of different serovars of Salmonella in a indirect ELISA with... |

| The aim of this work was to produce and characterize monoclonal antibodies anti bovine immunoglobulin G (IgG). Out of seven hybridomas, two were chosen based on the ELISA'S absorbance values and were labeled B4F11 and B3H12. These monoclonals were analyzed through Western Blot for IgG fragments obtained by proteolysis with papain, separated by electrophoresis in polyacrylamide gel electrophoresis with β-mercaptoetanol as reducing agent. This revealed that, possibly, the B4F11 was directed to a conformational antigen, and that B3H12 reacted in a specific fashion with Fc (Bovine IgG crystallizable fragment). This antibody could be used in the development of reagents to immunoassays relevant for research and diagnosis. |
