A LONG~ERM STUDY OF "MICROCELL " DISEASE IN OYSTERS WITH A DESCRIPTION OF A NEW GENUS, MIKROCYTOS (Go No), AND TWO NEW SPECIES, MIKROCYTOS MACKINI (SP. No) AND MIKROCYTOS ROUGHLEYI (SP. No)
Continuing long-tenn studies of oyster disease problems have been carried out over the past 26 years using field monitoring, gross, histologic, and ultrastructural pathologic methods. A microorganism of uncertain taxonomy was discovered in 1963 by J. G. Mackin in association with lesions and mortali...
