Emerald tree boas (Corallus batesii) are boids that in situ occurs in forested habitats in the Amazon Basin. The mycobacterial species can infect reptiles but the species Mycolicibacterium fortuitum was identified only in feces samples of ex situ Python regius and was isolated from granulomatous lesions of an ex situ Iguana iguana when was still part of the genus Mycobacterium. This article aims to report a mycobacteria infection case in a female Corallus batesii kept under human care. The animal presented apathy and 2 months of anorexia, being found dead. The necropsy revealed presence of tracheal and pulmonary nodules besides multifocal, bacterial, granulomatous pneumonia. After Fite-Faraco histochemical staining, immunohistochemistry, semi-nested polymerase chain reaction (PCR) and genetic sequencing the Mycolicibacterium fortuitum complex was diagnosed with 99.54% of nucleotide similarity. This mycobacterial species was already pointed out as an important nosocomial pathogen and more studies are necessary to explore their zoonotic potential.
翠青蛇（Corallus batesii）是一种分布于亚马逊盆地森林栖息地的蛇类。分枝杆菌可感染爬行动物，但仅在体外饲养的巨蟒和巨蜥的粪便样本中发现了偶发分枝杆菌，且该菌从巨蜥属巨蜥的肉芽肿病变中分离出来。本文旨在报告一例人类饲养的翠青蛇感染分枝杆菌的病例。该动物表现出冷漠和 2 个月的厌食症，最终死亡。尸检显示气管和肺结节以及多发性、细菌性、肉芽肿性肺炎。经 Fite-Faraco 组织化学染色、免疫组织化学、半巢式聚合酶链反应（PCR）和基因测序，鉴定出偶发分枝杆菌复合体，其核苷酸相似度为 99.54%。该分枝杆菌已被指出是一种重要的医院病原体，需要更多的研究来探索其人畜共患病的潜力。
