USE OF A NEW ISOLATE OF NEOSPORA CANINUM FOR THE DEVELOPMENT OF DIAGNOSTIC TESTS AND FOR PREPARATION OF PRODUCTS FOR TREATMENT AND PREVENTION OF THE INFECTION CAUSED BY NEOSPORA

摘要

The present invention relates to the use of a new isolate of Neospora caninum for the development of diagnostic tests and for the manufacture of products for the treatment and prevention of the infection caused by Neospora. The use of a new isolate of Neospora caninum (filed in the Culture Collection of Algae and Protozoa, with access number CCAP 2051/1), and the extracts obtained therefrom, in the preparation of diagnostic tests and in the manufacture of products for the treatment and prevention of the infection caused by Neospora, is based on the ease with which the new isolate converts from the tachyzoite to the bradyzoite stage under in vitro conditions. Additionally and with the same applications, the polypeptides and the polynucleotides obtained from the new isolate and the immunoreactive antibodies developed against Neospora antigens are used.
