Patent number: 6998126Abstract: A method for obtaining an immunogenic strain useful for producing a vaccine against Coccidiosis comprises the cycle of infecting at least one first group of specific pathogen-free donor birds with oocysts from an Eimeria species. Blood is then collected from these donor birds, and is then used to infect a second group of specific pathogen-free birds. Oocysts are collected from the second group of birds. These oocysts are then multiplicated to complete the cycle. The cycle is then repeated using the multiplicated oocysts. After a total of about three cycles, a final antigen may be harvested and utilized as a source to generate oocysts for a vaccine.Type: GrantFiled: February 21, 2003Date of Patent: February 14, 2006Assignee: WyethInventor: Frans Gerrit Davelaar

Patent number: 6171607Abstract: The present invention is a unique process and apparatus for making a new matrix material called a shearform matrix which results in transformation of the morphology of a feedstock. The process is characterized by increasing the temperature of a nonsolubilized feedstock carrier to a point where it will undergo internal flow, followed by upwardly ejecting a stream of the feedstock and then subjecting it to disruptive fluid shear force which separates it into separate parts or masses which have a transformed morphology. The shearform matrix may include other ingredients such as oleaginous material and actives.Type: GrantFiled: September 28, 1998Date of Patent: January 9, 2001Assignee: Fuisz Technologies Ltd.Inventors: Richard C.
