Blood from the cockroach Periplaneta americana usually does not react with a suspension of Micrococcus lysodeikticus. When lysozyme is added to the mixture it causes an immediate reduction in the optical density at 450 nanometers which is soon followed by a strong rise. Blood from roaches injected with lysozyme causes a similar series of changes in the optical density of a suspension of M. lysodeikticus, an indication that lysozyme has been retained in the blood. It may persist for many days or weeks.
美洲大蠊的血液通常不会与溶壁微球菌悬液发生反应。当向混合物中加入溶菌酶时，会导致450纳米处的光密度立即降低，随后很快会大幅上升。注射了溶菌酶的蟑螂的血液会使溶壁微球菌悬液的光密度发生类似的一系列变化，这表明溶菌酶已保留在血液中。它可能会持续存在许多天或数周。
