Topic:Antisera
Antisera refer to blood serum containing antibodies against specific antigens, produced by the immune system in response to exposure to these antigens. In horses, antisera are commonly used for therapeutic and diagnostic purposes, particularly in the treatment of venomous bites or stings, and in combating infectious diseases. The production of equine antisera involves immunizing horses with a particular antigen and subsequently collecting and processing their blood to extract the serum rich in antibodies. This page compiles peer-reviewed research studies and scholarly articles that explore the production, application, and efficacy of antisera in equine medicine, as well as advancements in safety and regulatory considerations in their use.
The alexination and conglutination reactions. The reactions between sensitized erythrocytes and horse complement and between alexinated erythrocytes and conglutinin. A method is described for the quantitative measurement of the reactions between sensitized cells and horse complement and between alexinated cells and conglutinin. The method is laborious but its application has allowed the determination of the optimal times of the reactions at various temperatures. The results obtained in these experiments indicate that the alexinated configuration with which conglutinin and immuno-conglutinin react is not one of the recognized intermediates formed during the process of immune haemolysis.
Immunochemistry of pneumococcal types II, V, and VI. II. Inhibition tests in the type VI precipitating system. Rebers, Paul A. (Rutgers University, New Brunswick, N. J.), Esther Hurwitz, and Michael Heidelberger. Immunochemistry of pneumococcal types II, V, and VI. II. Inhibition tests in the type VI precipitating system. J. Bacteriol. 82:920-926. 1961.-As in other immune systems involving polysaccharides, rabbit antibodies but not those engendered in the horse were found sensitive to degradation of type VI pneumococcal (Pn) polysaccharide (SVI), and were readily inhibited by fragments of SVI. Large amounts, 30 to 111 mumoles, of most sugars gave up to 15% inhibition, while sugar and polyol phosphates ...
Hemagglutination-inhibition and serum neutralization response of horses to eastern equine encephalomyelitis virus. Four horses inoculated with EEE virus remained asymptomatic following injection but did develop measurable HI and neutralizing antibodies as a result of infection. HI antibodies were detectable earlier than neutralizing antibodies but the levels tended to drop more rapidly. 2. Of 14 horses and ponies having significant levels of neutralizing antibody, 5 to 9 had measurable HI antibody depending on number of units of antigen employed in the test. 3. Sera from 3 clinical cases of EEE were positive on the HI test while only one of these animals had a significant neutralizing antibody level.
