| 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... |

| 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... |

| 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.... |

| 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,... |

| 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. |

| 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. |

| Monoclonal antibodies (Mabs) have been useful for immunoscintigraphic applications in clinical diagnosis since they were introduced in the practice of nuclear medicine. The ior egf/r3 (Centis, Cuba) is a murine monoclonal antibody against epidermal growth factor receptor (EGF-R) and has been widely used in the radioimmunodiagnosis of tumors of epithelial origin. Labeled with 99mTc, its main application in Nuclear Medicine is the follow up, detection and evaluation of tumor recurrences. The objective of this work is to describe the preparation of a lyophilized formulation (kit) for radiolabeling the Mab ior egf/r3 with 99mTc for immunoscintigraphic applications. Radiolabeling efficiency, effects on immunoreactivity, image studies and stability of the... |

| 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.... |

| We have raised monoclonal antibodies (mAbs) directed towards amastigote forms of Trypanosoma cruzi, and shown that mAbs 1D9 and 4B9 are carbohydrate while mAb 4B5 activity is resistant to periodate oxidation of the antigen. Here we used an ELISA to quantitate and compare the expression of surface epitopes on fixed parasites among different parasite isolates. The expression of markers varied among T. cruzi amastigotes isolated from infected cells or after extracellular differentiation of trypomastigotes. Moreover, we also observed an extensive polymorphic expression of these epitopes among amastigotes derived from different strains and clones. For instance, mAb 2C2 strongly and evenly reacted with 9 strains and clones (G, Y, CL, Tulahuen, MD, and F, and... |
