Abstract: A protocol to enumerate particle-associated microbial indicator bacteria (heterotrophic plate count [HPC], enterococci [ENT] and Clostridium perfringens [CP]) by membrane filtration in a tropical stream is proposed that relies on high-speed homogenization and chemical treatment. Application of this protocol to stream samples suggest that ENT measurements are more biased by the presence of aggregates than HPC or CP. Whole sample treatment typically increased the colony forming units (CFU) count by 9-52%. Analys…
