ABSTRACT
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 × 10³ to > 2.4 × 10(6) MPN.g-1, and TTC ranging from > 2.4 × 10³ to 2.9 × 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.
RESUMO
Amostras de água e cirrípedes Amphibalanus amphitrite foram coletados em Recife, Brasil, para avaliar se estes acumulam coliformes totais (CT) e termo-tolerantes (TTC) relacionados à poluição por esgoto doméstico. Foram utilizados os valores de Números Mais Prováveis (NMP) e os procedimentos padrões para exame de bivalves. Comparativamente às amostras de água, os valores mais altos de coliformes foram dos cirrípedes, com valores de TC variando de < 3,0 × 10³ a > 2,4 × 10(6) NMP.g-1, e TTC variando de > 2,4 × 10³ a 2,9 × 10(5) NMP.g-1. Os cirrípedes acumularam TC Ewingella americana e TTC Escherichia coli, Enterobacter gergoviae, Enterobacter aerogenes e Enterobacter sakazakii. Os resultados proveram uma indicação de que há contaminação orgânica nas localidades de amostras e que esta espécie pode ser um bioindicador bom de poluição orgânica.
