Nontuberculous mycobacteria (NTM) are environmental bacteria commonly found in soil and water in almost every part of the world. While usually non-pathogenic, they can cause acute respiratory and cutaneous infections under certain circumstances or in patients with underlying medical conditions. Contrary to members of the complex, documented human-to-human transmissions of NTM have been rarely reported and most cases result from direct environmental exposure. Here we describe the identification of a new NTM species isolated from a hand laceration of a New York State patient after a fall. This new NTM forms rough, orange pigmented colonies and is naturally resistant to doxycycline and tobramycin. Whole genome analysis reveal no close relatives present in public databases, and our findings are in accordance with the recognition of a new taxonomic species of NTM. We propose the name sp. nov. for this new NTM representative. The type strain is 20-157661T (DSM = 113368T, BCCM = ITM 501207T).
非结核分枝杆菌（NTM）是一种环境细菌，在世界几乎每个地区的土壤和水中都普遍存在。虽然它们通常不具有致病性，但在某些情况下或患有基础疾病的患者中，它们可引起急性呼吸道和皮肤感染。与结核分枝杆菌复合体成员不同，NTM的人际传播鲜有报道，大多数病例是由于直接接触环境所致。在此，我们描述了从一名纽约州患者跌倒后手部撕裂伤中分离出的一种新的NTM物种的鉴定情况。这种新的NTM形成粗糙的橙色色素菌落，对强力霉素和妥布霉素天然耐药。全基因组分析显示公共数据库中没有近亲，我们的发现符合对一种新的NTM分类物种的认可。我们提议将这种新的NTM代表命名为 新种。模式菌株为20-157661T（DSM = 113368T，BCCM = ITM 501207T）。
