Human activity directly or indirectly causes climate change, promoting changes in the composition of the atmosphere. This change is beyond the variation of the natural climate. In this manner, climate change could create an environmental pressure which is enough to trigger new fungal diseases. In addition to climate alterations, the onset of the COVID-19 pandemic has also been associated with the emergence of fungal pathogens. Fungi showed that an inability to grow at high temperatures limits the capacity of fungi to infect mammals. However, fungi can develop thermotolerance, gradually adapting to rising temperatures due to climate change, and generating a greater number of disease-causing organisms. In the present study, we reported the detection and identification of isolates recovered from raw sewage samples in Niteroi city, Rio de Janeiro State, Brazil, during a monitoring program for measuring SARS-CoV-2 presence and concentration. Using polyphasic taxonomy to identify the species and evaluating some virulence aspects of this species, such as biofilm formation and extracellular enzyme production, our data highlight this species as a possible emerging pathogen in Brazil, especially in the pandemic context.
人类活动直接或间接导致气候变化，促使大气成分发生变化。这种变化超出了自然气候的波动范围。通过这种方式，气候变化可能会产生足以引发新的真菌疾病的环境压力。除了气候改变之外，新冠疫情的爆发也与真菌病原体的出现有关。真菌表现出在高温下无法生长限制了其感染哺乳动物的能力。然而，真菌可以产生耐热性，由于气候变化逐渐适应不断上升的温度，并产生更多致病生物体。在本研究中，我们报告了在巴西里约热内卢州尼泰罗伊市的一项测量新冠病毒存在和浓度的监测计划期间，从未经处理的污水样本中分离出的菌株的检测和鉴定情况。利用多相分类法鉴定该物种，并评估该物种的一些毒力特性，如生物膜形成和细胞外酶产生，我们的数据突出了该物种作为巴西尤其是在疫情背景下可能出现的病原体。
