The performance of a liquid chromatographic (LC) method for spiramycin measurement in bovine plasma has been compared with that of a microbiological method. Plasma samples were obtained from cattle administered spiramycin intravenously. Comparison tests used were intraclass correlation (r1), correlation (r), and Student's paired t-test. For concentrations lower than 2.5 IU/mL, microbiological values were higher than LC values. This difference in results modified pharmacokinetic interpretation and might be explained by the presence of microbiologically active metabolites.
