title: [Viral flora (coliphages and human enteroviruses) found in river water after an urban district (Saint-Etienne). I. Comparative study of four simple and inexpensive methods for concentration and isolation of river-water viruses (author's transl)].
abstract: Four methods for the concentration of human enteroviruses in the waters of the river Furan were surveyed: the original method described by WALLIS, of adsorption of viruses on PE-60 polyelectrolyte; a modified version of the Wallis method; a method using a different polyelectrolyte available in France, the POE; the two-phase system described by SHUVAL. The best results were obtained when using the method of adsorption on polyelectrolytes, and the second method was finally chosen for field surveys.
