Turicella otitidis is a gram-positive bacillus coryneforme described, after 16S RNA sequencing, in 1994 by Funke et al as a microorganism involved in otitis media, and it is in health conditions a habitual colonizer of the external auditory canal. Since its description, more than twenty years ago, few cases of otitis related to or directly attributed to this microorganism have been published.
Description of a case of mastoiditis that required surgery and other cases of otic pathology in which T. otitidis was isolated, in the second semester of 2017 in our institution. They were reported only when they grew in pure culture. The identification was made by mass spectrophotometry and an antibiogram was performed.
In our institution in the second half of 2017, 5 cases of otitis media were documented, some of them complicated, in which T. otitidis was isolated. The most of patients were children with recurrent otic pathology, and in some cases the sample was taken before the administration of antibiotics.
Since the inclusion of new vaccines that protect against microorganisms typically causing otitis media, is possible there are a change in the etiology of this disease and that microorganisms anecdotally isolated until now have become protagonists. The improvement in the microbiological identification provided by tools such as mass spectrometry will help to clarify if there are or not a change in the etiology of these diseases.
耳道Turicella菌是一种革兰氏阳性棒状短小杆菌，1994年Funke等人经16S RNA测序后将其描述为一种与中耳炎有关的微生物，在健康状况下它是外耳道的常见定植菌。自二十多年前被描述以来，很少有与该微生物相关或直接由其引起的中耳炎病例被报道。
描述2017年下半年在我们机构发生的一例需要手术治疗的乳突炎病例以及其他分离出耳道Turicella菌的耳部病理病例。仅当它们在纯培养物中生长时才进行报告。通过质谱分析法进行鉴定并开展药敏试验。
2017年下半年在我们机构记录了5例中耳炎病例，其中一些为复杂性病例，均分离出了耳道Turicella菌。大多数患者为患有复发性耳部疾病的儿童，在某些情况下，样本是在使用抗生素之前采集的。
自从纳入了针对通常引起中耳炎的微生物的新型疫苗后，这种疾病的病因有可能发生了变化，并且迄今为止偶尔分离出的微生物已成为主要因素。质谱分析等工具提供的微生物鉴定方面的改进将有助于明确这些疾病的病因是否发生了变化。
