[Detection and persistence of human-pathogenic viruses in chemical sludge (author's transl)].
Virological investigations, using poliovirus type I, were carried out on the detection of enterovirus and their persistence in the chemical sludge from a tertiary treatment process, which could be suitable for agricultural and horticultural applications.--A comparison of six eluents showed that tryptose phosphate broth yielded best results allowing approximately 30% overall recovery with the method described. With sludge of low virus content a concentration was possible with alginate filters and the phase separation method.--Examinations on the persistence of poliovirus show that at 5 degrees C and 10 degrees C the inactivation was slow and that virus was detectable over a 15 week period at 5 degrees C.
