Cryptosporidium spp. are protozoa which infect a wide variety of vertebrates. Cryptosporidium parvum has many animal hosts, including humans, and is a major etiological agent of diarrhea in ruminants. The Cryptosporidium oocysts wall proteins (COWP) are a group of proteins located on the surface of the oocyst wall and are involved in its structure and resistance of oocysts in environmental conditions. COWP proteins are potential targets for cloning and heterologous expression in E. coli, for the production of recombinant proteins useful for the development of diagnostic methods like direct immunofluorescence assay (DIA), and also for isolation and purification of oocysts using immunological techniques. The aims of this study are the cloning, expression and purification of C. parvum COWP5 recombinant protein, followed by immunization of laying hens in order to obtain IgY anti-COWP5. After obtaining polyclonal IgY, it will be accomplished the development of DIA for detection of C. parvum oocysts. (AU)
