Chlamydiae (with phages), mycoplasmas, and richettsiae in Chesapeake Bay bivalves.

Intracytoplasmic chlamydia-like organisms, some with phages, rickettsia-like organisms, and mycoplasma-like organisms have been found in clams and oysters from the Chesapeake Bay area by electron microscopy. None of these organisms have been previously detected in mollusks, nor have phages been previously observed in Chlamydia sp.
