外耳道細菌叢之研究1.癌症病人

Bacterial Flora of the External Ear Canal 1. Cancer Patients

摘要


為了解罹息癌症,是否影響外耳這細菌業,64 名經過篩減的頭頸部癌症病息,做了外耳這細菌學研究,並與文獻上正常外耳道細繭業及外耳這炎之細繭業比較,發現能引發外耳這炎的革蘭氏陰性菌增加很多(59.4%)。雖然Staphylococcus epidermi-dis還是最多(48.5% ),但是 PSeudomonas Sp.(18.8%)及 Flavobacterium sP.(16.8 % )高居第二及第三位“而且也發現有細菌的外耳道,有一半(48.5%)至少有一種革蘭氏陰性菌。因此鄴門確信頭頸部癌症,比較寡易罹患外耳道炎,與細菌業之改變有關。

The bacterial flora of the external ear canal was investigated in a group of 64 patients with head and neck cancer, to observe why otitis externa frequently occurs in cancer patients. Staphylococcus epidermidis (48.5%), Pseudomonas sp. (18.8%), and Flavobacterium sp. (16.8%) were the prominent isolates from ear samples, and Gram-negative organisms which rarely existed in normal canal, were found to be markedly increased (59.4%). Moreover, about half of all non-sterile ear canals were found to have more than one Gram-negative flora. We have concluded that cancer patients probably suffer from external otitis more frequently because of enhanced colonization by Gram-negative pathogens.
