Fructosamine measurement in ponies: validation and response following experimental cyathostome infection.
Validation of an assay for measurement of fructosamine in equine serum and plasma utilised blood samples collected from 24 British native breed ponies. The results indicated that fructosamine can be measured easily using an assay which is precise and accurate. Paired plasma and serum fructosamine measurements were highly correlated, however, greater variations were observed within serum compared with those in plasma. A reference range for fructosamine in plasma was calculated to be 256.9 +/- 60.6 mumol litre-1 (mean +/- 2 SD). In order to assess the fructosamine response following experimental cyathostome infection, nine British native breed ponies were allocated to one of three groups: Group 1 (3.9 million third-stage cyathostome larvae (L3) over a nine-week-period), Group 2 (3.15 million L3 over seven weeks) and Group 3 (uninfected controls). From four weeks prior to infection, blood was obtained, once weekly, from all animals for measurement of plasma fructosamine, plasma albumin and serum globulin concentrations. Plasma fructosamine concentrations decreased in all infected ponies post-infection due to enteric protein loss and/or altered protein composition and/or increased protein turnover.
