The association of parasites and diatoms has been previously reported as an important mechanism to control bacteria and parasites to avoid resistance to chemical usage. The aim of this study was to investigate the association between diatoms genus and parasites within the gastrointestinal compartments (GICs) of commercial fish in fisheries of the marine Pacific coast of Colombia (Buenaventura). A total of 104 GICs from marine fish were sampled. The GICs analysis revealed 14 diatom genera (N = 14). The most prevalent were Coscinodiscus spp., which was present in 58/104 samples, 55.8% [95% CI = 37.5-62.1%]; Cyclotella spp., 28/104, 26.9% [95% CI = 0-25%]; Paralia spp., 26/104, 25% [95% CI = 12.5-44.8%]; Gyrosigma spp., 11/104, 10.6% [95% CI = 0-33.3%]; Navicula spp., 11/104, 10.6%, [95% CI = 0-20.7%]. The GICs analysis revealed a diversity of genera parasites. The most prevalent were Ameboid cysts, 25/104, 24% [95% CI = 12.5-48.3%]; Eimeria spp., 11/104, 10.6% [95% CI = 10.3-15.7%]; Anisakis spp., 29/104, 27.1% [95% CI = 27.1 (SD±12.9%)]. This is the first report concerning diatoms and parasites association in fish from the Pacific Coast of Colombia and highlights the relevance of Coscinodiscus spp. and Gyrosigma spp. as important diatoms and potential candidates for studying pharmaceutical action in aquaculture. Further studies about diatoms-parasites association in aquaculture are required.
寄生虫与硅藻的关联此前已被报道为控制细菌和寄生虫以避免产生化学药物抗性的一种重要机制。本研究的目的是调查哥伦比亚太平洋沿岸（布埃纳文图拉）渔业中商业鱼类胃肠道内（GICs）硅藻属与寄生虫之间的关联。共采集了104份海鱼的GICs样本。对GICs的分析揭示了14个硅藻属（N = 14）。最常见的是圆筛藻属（Coscinodiscus spp.），存在于58/104个样本中，占55.8% [95%置信区间 = 37.5 - 62.1%]；小环藻属（Cyclotella spp.），28/104个样本，占26.9% [95%置信区间 = 0 - 25%]；拟菱形藻属（Paralia spp.），26/104个样本，占25% [95%置信区间 = 12.5 - 44.8%]；布纹藻属（Gyrosigma spp.），11/104个样本，占10.6% [95%置信区间 = 0 - 33.3%]；舟形藻属（Navicula spp.），11/104个样本，占10.6%，[95%置信区间 = 0 - 20.7%]。对GICs的分析还揭示了多种寄生虫属。最常见的是阿米巴样囊肿，25/104个样本，占24% [95%置信区间 = 12.5 - 48.3%]；艾美耳属（Eimeria spp.），11/104个样本，占10.6% [95%置信区间 = 10.3 - 15.7%]；异尖线虫属（Anisakis spp.），29/104个样本，占27.1% [95%置信区间 = 27.1（标准差±12.9%）]。这是关于哥伦比亚太平洋沿岸鱼类中硅藻与寄生虫关联的首份报告，并突出了圆筛藻属和布纹藻属作为重要硅藻以及水产养殖中药物作用研究潜在候选者的相关性。需要对水产养殖中硅藻 - 寄生虫的关联进行进一步研究。
