RESUMO
A bacteriophage was isolated specific for Sphaerotilus natans, an organism for which bacteriophages have not been previously described. This phage (designated SN1) was found to infect both the single-cell (S-type) and filamentous (R-type) forms of the host, although the sheath appeared to provide R-type cells with a degree of physical protection from infection. SN1 had a hexagonal head and a long flexible tail resembling most closely the phages in Bradley's group B. The nucleic acid was found to be deoxyribonucleic acid and contained an unusual base which substituted for 35% of the guanine. Deoxyribonucleic acid base composition was 56% cytosine plus guanine.
