Abstract

The conditions of helium saturation diving promote the proliferation of Gram-negative bacterial species in the external auditory meatus of divers. These changes in flora occurred in the absence of operational diving, that is, no contact with water. The colonising bacteria were autogenous in origin and cross-colonisation was observed between divers. On return to normal atmospheric conditions the aural flora became predominantly Gram-positive again within 48 hours.

摘要

氦饱和潜水条件会促使潜水员外耳道革兰氏阴性菌种类的增殖。这些菌群变化在未进行实际潜水操作(即未接触水)的情况下也会发生。定殖细菌源自自身,且在潜水员之间观察到了交叉定殖现象。回到正常大气条件后,耳内菌群在48小时内又再次以革兰氏阳性菌为主。
