It was shown that the residual amounts of tetracyclines adsorbed on membrane filters may be inactivated by addition of 2M magnesium sulphate solution to the agar for placing the filters after filtration. The antibiotic inactivation increases the possibilities of the test for antibiotic sensitivity of the microflora present in the drugs and may be used in determination of microbial dissmination of non-injection tetracyclines.
结果表明，对于过滤后放置在琼脂中的膜滤器，通过向琼脂中加入2M硫酸镁溶液可使吸附在膜滤器上的四环素残留量失活。抗生素失活增加了检测药物中存在的微生物对抗生素敏感性的可能性，可用于测定非注射用四环素的微生物扩散情况。
