  • Adenovirus Adenovirus is an enteric virus that can persist under certain environmental conditions and is used in some contexts as a reference for evaluating viral persistence in water.
  • Viable bacteria Viable bacteria are microorganisms capable of remaining alive and, depending on conditions, growing or forming colonies detectable by culture methods.
  • Bacteriophage A bacteriophage is a virus that infects specific bacteria and replicates within them. In water quality, bacteriophages are used as viral models or indicators to study fecal contamination, treatment behaviour and microbiological barrier performance.
  • Biofilm A biofilm is a microbial community attached to a surface and protected by an extracellular matrix. In water networks it can act as a reservoir of microorganisms and contribute to recontamination.
  • Microbial load Microbial load is the level of microorganisms present in a sample or system. It can be expressed in different units depending on the method and organism evaluated.
  • Host strain A host strain is the bacterium used as the host to detect or enumerate bacteriophages in culture methods. Its selection is critical for assay sensitivity and result interpretation.
  • Total coliforms Total coliforms are a broad group of indicator bacteria that may occur in soil, water or fecal environments. They are used to assess system integrity, treatment effectiveness and possible operational issues.
  • F-RNA coliphages F-RNA coliphages are a subgroup of F-specific coliphages with an RNA genome. They can be used in fecal contamination and viral behaviour studies depending on method, matrix and program objective.
