Abstract
Ten phages which use the LamB protein for adsorption have been isolated from sewage waters. Nine have a shape similar to lambda and require only the LamB protein for adsorption. One has a shape similar to T phages and can use either the LamB or the OmpC protein. Preliminary characterization by a number of criteria showed that at least 9 of these phages were different and also differed from other known phages which use the LamB protein, such as lambda, 21 and K10.
