The proteins are effective for the immunization of a variety of animals against , particularly for the production of hyperimmune colostrum that may be used to confer passive immunity against the parasite. Isolated DNA sequences which encode these proteins have also been developed. The DNA sequences may be inserted into recombinant DNA molecules such as cloning vectors or expression vectors for the transformation of cells and the production of the proteins.

International Classification:

G06F 17/30

US Classification:

707 3

Abstract:

An Internet web-based system which provides a discrete visual container of multimedia information with interactive functionality using what are termed here cards which are objects displayed on the user's computer screen providing information. The cards can be saved, edited, searched, manipulated, linked and embedded. Unlike conventional web pages, the cards are not created using HTML or any other programming language, but are instead created using an editor thus not requiring programming expertise by the creator. Moreover a group of cards may be provided as a set so that all the information on the stack of cards is available without downloading or hyperlinking. Also provided is a card stack which is a set of cards all displayed simultaneously on one user computer display screen typically in an overlapping fashion where the cards in the set have some relationship to one another. The card stack, like a single card, may be saved, edited, searched, manipulated, linked or embedded.

Abstract:

Disclosed are DnA sequences which code for antigenic proteins, methods for identifying such DNA sequences, and antigens coded for by such DNA sequences. The first step of the method is to provide a multiplicity of DNA sequences. These sequences are then inserted into DNA expression vectors to form recombinant expression vectors. The expression vectors are inserted into suitable hosts to form transformants which express the DNA sequences. The transformants are then contacted with antibodies directed against Eimeria antigens to identify transformants containing DNA sequences which code for Eimeria antigens. These antigens are then produced from the DNA sequences identified as coding for the antigens. The antigens so produced are contacted with white blood cells which effect a cell-mediated immune response, which white blood cells are sensitized to an antigenic Eimeria protein, to thereby identify DNA sequences which code for antigens that induce a cell-mediated immune response to avian coccidiosis. The DNA sequences of the present invention comprise cloned genes or fragments thereof that code on expression for an antigenic protein that activates white blood cells which effect a cell-mediated immune response, which white blood cells are sensitized to an antigenic Eimeria protein.
