摘要:
The invention pertains to a method to sporulate coccidial oocysts purified from animal faeces (5), the method comprising providing the purified oocysts as a layer (40) on a supporting surface (22), maintaining the layer at least intermittently in an oxygen containing gaseous environment (60) having a relative humidity of at least 15% and maintaining the temperature of the oocysts between 19° C. and 37° C. The invention also pertains to sporulated oocysts obtained with this method and to a vaccine containing such sporulated oocysts.
摘要:
The present invention relates to vaccine compositions comprising attenuated strain of Tilapia Lake Virus (TiLV) for protecting tilapia fish against infection by (TiLV). The invention also relates to methods for using the vaccines to protect tilapines from TiLV-induced disease.
摘要:
Vaccines comprising TRAP polypeptides and Salmonella enteritidis vectors comprising TRAP polypeptides are provided. The vaccines may also include a CD 154 polypeptide capable of binding to CD40. Also provided are methods of enhancing an immune response against Apicomplexan parasites and methods of reducing morbidity associated with infection with Apicomplexan parasites.

摘要:
Contemplated compositions, devices, and methods are drawn to various antigens from the pathogen T. gondii and their use in various diagnostic tests, vaccines, and therapeutic agents. In particularly preferred aspects, the antigens are immunodominant and have quantified and known relative reactivities with respect to sera of a population infected with the pathogen, and/or have a known association with a disease parameter.
摘要:
Potato leaf transformed by a vector which expresses an immunogenic protein gene R7 originating in the second generation schizont of Leucocytozoon caulleryi is administered as an oral vaccine to chickens. As a result, the antibody titer of the chickens can be successfully elevated.
