This study investigates bacterial diversity and potential pathogens in the international ships' ballast water at Tanjung Pelepas Port, Malaysia, using 16S rRNA amplicon sequencing. Thirty-four bacterial phylum, 305 families, 577 genera, and 941 species were detected in eight ballast water samples of different origins. The similarity of the bacterial composition between samples was found to be random and not tied to geographical locations. The bacterial abundance did not seem to be affected by related physicochemical except for temperature. Ballast water samples with a temperature lower than 25 °C showed a relatively lower bacterial abundance. A total of 33 potential pathogens were detected from all ballast water samples. Pseudomonas spp., Tenacibaculum spp., Flavobacteriaceae spp., Halomonas spp., and Acinetobacter junii are the potential pathogens with more than 10% OTU prevalence. This study would provide beneficial information for further enhancing ballast water microorganism guidelines in Malaysia.
本研究采用 16S rRNA 扩增子测序技术，调查了马来西亚丹戎帕拉帕斯港国际船舶压载水中的细菌多样性和潜在病原体。在 8 个不同来源的压载水样本中检测到 34 个细菌门、305 个科、577 个属和 941 个种。样本间细菌组成的相似性是随机的，与地理位置无关。细菌丰度似乎不受相关理化因素的影响，除了温度。温度低于 25°C 的压载水样本显示出相对较低的细菌丰度。从所有压载水样本中总共检测到 33 种潜在病原体。假单胞菌属、Tenacibaculum 属、黄杆菌科、盐单胞菌属和不动杆菌属 junii 是具有超过 10%OTU 流行率的潜在病原体。本研究将为进一步加强马来西亚压载水微生物指南提供有益信息。
