The invention pertains to a method to purify coccidial oocysts having dimensions between Dmin and Dmax from faeces comprising the steps of collecting the faeces containing the coccidial oocysts from host animals, diluting the faeces in an aqueous medium, separating a coarse fraction comprising macroscopic particulate matter from the diluted faeces and collecting an aqueous fraction containing the oocysts, characterised in that the method further comprises sieving the aqueous fraction over a first sieve deck having mesh openings to let the oocysts pass, to obtain an aqueous filtrate comprising the oocysts and a first residue comprising particles larger than the oocysts, and sieving the aqueous filtrate over a second sieve deck having mesh openings to obstruct passing of the oocysts through this sieve deck, to obtain a second residue comprising the purified oocysts and a waist filtrate comprising particles smaller than the oocysts. The invention also pertains to a system suitable for applying this method and to oocysts obtained therewith.

The invention pertains to a method to sporulate coccidial oocysts purified from animal faeces (), the method comprising providing the purified oocysts as a layer () on a supporting surface (), maintaining the layer at least intermittently in an oxygen containing gaseous environment () having a relative humidity of at least 15% and maintaining the temperature of the oocysts between 19&#xb0; C. and 37&#xb0; C. The invention also pertains to sporulated oocysts obtained with this method and to a vaccine containing such sporulated oocysts.

The present invention generally relates to the fields of parasitology and immunology, and especially to a vaccine againstticks. In particular the invention relates to a composition comprising a first and a second protein, in particular Bm86 and Subolesin proteins, including their homologs or immunogenic fragments; to the use of such a composition as a vaccine againstticks, and to the use of the first and the second isolated proteins for the vaccination of a target againstticks.

Vaccine against Rhipicephalus ticks

The present invention relates to the field of veterinary parasitology, especially of canine Babesiosis. In particular the invention relates to a polypeptide being a novel canineantigen (CBA), or fragments thereof, and to compositions comprising this antigen, to nucleic acids encoding the antigen, antibodies against the antigen, and medical uses of this antigen, fragments, antibodies, or encoding nucleic acids. In particular the invention relates to the use of such components in vaccines against canine Babesiosis.
