{{Short description|Bacteriophage that infects coliform bacteria}}
A '''coliphage''' is a type of [bacteriophage](/source/bacteriophage) that infects [coliform bacteria](/source/coliform_bacteria) such as ''[Escherichia coli](/source/Escherichia_coli)''. Coliphage originate almost exclusively from [human feces](/source/human_feces) and from other [warm-blooded](/source/warm-blooded) animals.<ref>{{Cite journal | vauthors = Grabow WO |date=2001-04-01 |title=Bacteriophages : update on application as models for viruses in water |url=https://journals.co.za/doi/10.10520/EJC115944 |journal=Water SA |volume=27 |issue=2 |pages=251–268 |hdl=10520/EJC115944 }}</ref> When certain circumstances are met, such as a large number of susceptible hosts present at the right temperature, they can only partially replicate in sewage and contaminated waters.

Examples include [''Enterobacteria phage λ''](/source/Lambda_phage) and species from the family [Fersviridae](/source/Fiersviridae). Coliphage levels reflect the persistence of [pathogenic viruses](/source/Pathogenic_virus) in the environment and have been proposed as an indicator of fecal contamination in water.<ref>{{cite journal | vauthors = Nappier SP, Hong T, Ichida A, Goldstone A, Eftim SE | title = Occurrence of coliphage in raw wastewater and in ambient water: A meta-analysis | journal = Water Research | volume = 153 | pages = 263–273 | date = April 2019 | pmid = 30735956 | pmc = 7169987 | doi = 10.1016/j.watres.2018.12.058 }}</ref>
