Electron micrograph of bacteriophage UrLambda
||Lambda is a member of the lambda-like (or lambdoid)
bacteriophage family. The phage normally used in laboratory
experiments do not have the long tail fibers you see here.
The head shells of lambda particles are 50 nm in diameter (T = 7), the tails are 150 nm in length,
and in "wild type" lambda tail fibers, if visible at all, are stubs that project from the junction
between the tail shaft and the tail spike.
Its known hosts include E. coli.
The electron micrograph shown at left is by
Bob Duda (University of Pittsburgh).
To see the size of lambda in relation to that of its host E. coli,
see this micrograph of a mob attack.
A sculpture of lambda is in the collection of
