Transmission of Loma salmonae (Microsporea) to chinook salmon in sea water.
Transmission studies were conducted to determine if Loma salmonae was transmissible in sea water. Transmission of L. salmonae to chinook salmon (Oncorhynchus tshawytscha) held in sea water was achieved by exposing fish to macerated, infected gill tissue. Fish were exposed in seawater in a flow-throu...
