Abstract

The emerging fungal pathogen Candida palmioleophila (C. palmioleophila) has been increasingly detected in environmental and animal samples, although studies in this regard are still scarce, especially in fisheries contexts. This study reports the first-time detection of C. palmioleophila in a commercially relevant fish species belonging to the Sciaenidae family (Cynoscion sp.), indicating its potential emergence as a pathogen in Brazil. We applied CHROMagar Candida Plus medium identification associated to Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) for the identification of C. palmioleophila isolates. Although only one fish specimen was shown to be contaminated by C. palmioleophila, this study provides the first evidence of this yeast circulating in commercially relevant fish species in Brazil, highlighting the potential risks associated with this emerging pathogen.

巴西东南部与商业有关的鱼类中新出现的嗜棕榈念珠菌致病性酵母的首次报告。
尽管在这方面的研究仍然很少,特别是在渔业环境中,但在环境和动物样本中越来越多地检测到新出现的真菌病原体念珠菌(C. palmioleophila)。本研究首次在一种与商业相关的鱼科(Cynoscion sp.)中检测到嗜棕榈线虫(C. palmioleophila),表明其可能在巴西作为一种病原体出现。我们采用CHROMagar Candida Plus培养基鉴定与基质辅助激光解吸/电离飞行时间质谱(MALDI-TOF MS)相结合的方法对嗜棕榈孢杆菌分离物进行鉴定。虽然只有一个鱼标本被嗜棕榈孢杆菌污染,但这项研究首次提供了这种酵母在巴西商业相关鱼类中循环的证据,突出了与这种新出现的病原体相关的潜在风险。
