Samples of water and barnacles Amphibalanus amphitrite were collected from Recife, Brazil, to assess if it accumulates total (TC) and thermotolerant coliforms (TTC) related with sewage pollution. The Most Probable Number (MPN) values and the standard procedures for examination of shellfish were used. Comparatively with the water samples, the highest coliform values came from the barnacles, with TC values ranging from < 3.0 x 10(3) to > 2.4 x 10(6) MPN.g-1, and TTC ranging from > 2.4 x 10(3) to 2.9 x 10(5) MPN.g-1. Barnacles accumulate the TC Ewingella americana, and the TTC Escherichia coli, Enterobacter gergoviae, Enterobacter aerogenes, and Enterobacter sakazakii. The results provided an indication of the level of organic contamination at the sampling locations and that this species could be a good organic pollution bioindicator.
从巴西累西腓采集了水样本和藤壶（纹藤壶）样本，以评估其是否积累了与污水污染相关的总大肠菌群（TC）和耐热大肠菌群（TTC）。采用了最可能数（MPN）值和贝类检测的标准程序。与水样相比，藤壶中的大肠菌群值最高，总大肠菌群值范围为<3.0×10³至>2.4×10⁶MPN·g⁻¹，耐热大肠菌群值范围为>2.4×10³至2.9×10⁵MPN·g⁻¹。藤壶积累了总大肠菌群美洲埃希氏菌，以及耐热大肠菌群大肠杆菌、杰氏肠杆菌、产气肠杆菌和阪崎肠杆菌。结果表明了采样地点的有机污染水平，并且该物种可能是一种良好的有机污染生物指示物。
