Topic:Comparative Study
Comparative studies in equine research involve the systematic analysis of different horse breeds, management practices, or physiological responses to identify variations and similarities. These studies are instrumental in understanding how different factors influence health, performance, and behavior in horses. Common areas of comparison include genetic traits, nutritional requirements, disease resistance, and response to training. By evaluating these differences, researchers can develop targeted strategies for breeding, healthcare, and training. This page aggregates peer-reviewed research studies and scholarly articles that focus on the methodologies, findings, and implications of comparative studies in the context of equine science.
Limitations of immunofluorescence tests in the diagnosis of infectious mononucleosis. The relative value of heterophil agglutinins (HA) and of specific EBV antibodies in the diagnosis of infectious mononucleosis (IM) was assessed in 108 cases of the disease and in 280 controls. Among the 108 cases 93 were HA-positive by sheep cells in at least one of their sera, while 15 were HA-negative by the same test. Among the 280 controls false-positive HA tests were not encountered except in eight cases with the horse cell microtitre tests. With one of the two slide tests at least two false-positive tests and 12 false-negative tests were also found but these sera had low titres in microt...
Comparison of SN and HI antibody dose response curves in chickens, rabbits, foals and horses following vaccination with equine influenza vaccine. After vaccination of chickens, rabbits, foals and horses, HI and SN antibody dose response curves were compared for A/Equi 1/Prague and A/Equi 2/Paris strains.
The two curves are parallel for a given strain and the relationship of HI and SN titres is constant, whatever the animal species.
The distribution of HI and SN titres varies for the two strains.
This variation, which is independent of animal species, may be related to the number of sites necessary for the antigenic-antibody response in vitro.
It is suggested that the testing of equine influenza vaccine be carried out in the ...
Reticuloendothelial clearance studies in the course of horse serum induced nephritis. Assessment of changes in activity of the reticuloendothelial system (RES), including the mesangial cells of the kidney, has been made by means of clearance studies of human aggregated gamma-globulin and of colloidal gold, during the course of horse serum sickness nephritis. RES blockade was found after protein loading and at the phase of circulating immune complexes. At other times RES activity was normal or increased. “Mesangial saturation” may have important implications for human nephritis.

Serum levels of the immunoglobulins IgG and IgG(T) in horses. Levels of the immunoglobulins IgG and IgG(T) in serum in Norwegian horses of the breeds “Døle” and “Fjord” were determined by the quantitative radial immunodiffusion test. No significant differences were apparent between the 2 Norwegian breeds. The immunoglobulin levels were approximately in the same range as previously reported for Shetland ponies. Immunoglobulins could not be detected in the newborn foal. As early as 24 hrs. after birth the mean immunoglobulin level was within the adult range. After a drop during the first month of life, the immunoglobulins increased. IgG(T) rose mo...
