Abstract:
New proteins and subunit antigens from P. haemolytica for use in stimulating immunity against respiratory diseases such as pneumonia, including shipping fever pneumonia, are disclosed. The subunit antigens include immunogenic amino acid sequences of P. haemolytica fimbrial protein, P. haemolytica plasmin receptor protein, and P. haemolytica 50 K outer membrane protein and P. haemolytica leukotoxin. The antigens can be used in a vaccine composition, either alone or in combination. Also disclosed are methods of vaccination as well as methods of making the subunit antigens employed in the vaccines.
Abstract:
Novel Polygala senega saponin pharmaceutical compositions are disclosed. The P. senega saponins are useful as immunological adjuvants to enhance immune responses to a co-administered antigen.
Abstract:
A starch cationization process comprises suspending the starch in an aqueous alcoholic alkaline solvent containing a critical level of water (starch to water ratio 1:3 to 3:1), heating the reaction mixture for a few minutes at 30-90 DEG C, adding a cationizing reagent such as 3-chloro-2-hydroxypropyl-trimethylammonium chloride, heating for 1-24 hours at 30-80 DEG C, neutralizing, centrifuging, washing and drying of the cake to yield cationic starches with degrees of substitution of 0.01 to 0.12. Amphoteric starches are produced by simultaneous or sequential reaction of an anionic reagent with or after the cationic reagent in the aqueous alcoholic alkaline solvent. Solvent recovery and concentration of effluent solids is facilitated by distillation.
Abstract:
Novel Quinoa saponin pharmaceutical compositions are disclosed. The compositions are useful as immunological adjuvants, to stimulate nonspecific immunity, as well as to enhance an immunological response to a selected antigen. The Quinoa saponin compositions can also be used to enhance mucosal absorption of a drug administered therewith.
Abstract:
Novel vaccines for use against Actinobacillus pleuropneumoniae are disclosed. The vaccines contain at least one Actinobacillus pleuropneumoniae outer membrane lipoprotein A, or an immunogenic fragment thereof. Also disclosed are DNA sequences encoding these proteins, vectors including these sequences and host cells transformed with these vectors. The vaccines can be used to treat or prevent porcine respiratory infections.
Abstract:
Novel Haemophilus somnus immunogenic proteins are disclosed. The proteins can be used in vaccine compositions for the prevention and treatment of H. somnus infections. The proteins are conveniently produced using recombinant technology.
Abstract:
The invention relates to a kit for the measurement of anion, cation or zwitterion availability in a medium or for the measurement of free inorganic ions in disrupted cells from plant or animal tissue. The kit comprises ion-exchange material having a measurable ion uptake potential for immobilizing available ions from the medium on the material following contact on the material with the medium or suspension. It also comprises means to remove particulate solids from the material after having contacted the medium with the material. Preferably, the ion-exchange material is cation and/or anion-exchange material in the form of rigid or flexible films, sheets, membranes or the like. The invention also relates to a method for the on-site in situ measurement of anion and/or cation availability in a solid medium and to a method for measuring free organic ions in cells from plant or animal tissue. It also relates to ion-exchange material for immobilizing available ions in soil, sediment or water media and to a cation and/or anion-exchange membrane buried underneath the surface of a soil sample or site, the membrane being in ion-exchange relationship with available ions in the soil. The present invention represents an improvement over the prior art in that it provides means for quickly determining ion availability in a particular media without the necessity of collecting media samples for laboratory testing.
Abstract:
Acute phase proteins and antibodies thereto are disclosed, as well as methods of determining the presence and severity of infection and tissue damage by testing for these proteins. 17.5 kDa, 23 kDa and 37 kDa proteins have been identified in bovine subjects suffering from both infection and chemically induced tissue damage. The proteins are indicative of the severity and prognosis of disease. Antibodies thereto are useful in diagnostic assays.
Abstract:
Novel vaccines for use against Actinobacillus pleuropneumoniae are disclosed. The vaccines contain at least one A. pleuropneumoniae transferrin binding protein and/or one A. pleuropneumoniae cytolysin and/or one A. pleuropneumoniae APP4. Also disclosed are DNA sequences encoding these proteins, vectors including these sequences and host cells transformed with these vectors. The vaccines can be used to treat or prevent porcine respiratory infections.
