The present disclosure provides a method of detecting the presence of a hypnozoite stage of Plasmodium vivax in a liver cell. In addition, the present disclosure provides compositions and methods of detecting the presence of a latent Plasmodium vivax infection in a subject and for treating the subject detected to be infected.

This invention is directed to vaccine compositions and methods of using the same to prevent infection.

The invention is based on the finding that incubating a Cryptosporidium gp40 protein with an aziridine, significantly increases its immunogenicity. When used as a vaccine, this allows a reduction of the dose, which improves economic feasibility and safety. Consequently the aziridine-treated gp40 can now be used as a safe and effective subunit-vaccine for humans or non-human-animals against Cryptosporidiosis. Specifically for new-born ruminants a vaccination by way of colostral transfer was found to be very effective in reducing clinical signs of Cryptosporidiosis, especially diarrhoea.
