First report and characterization of Tenacibaculum maritimum isolates recovered from rainbow trout ( Oncorhynchus mykiss) farmed in Chile
Abstract The present study reports on the first isolation of Tenacibaculum maritimum in rainbow trout ( Oncorhynchus mykiss ) farmed in Chile. In March 2020, two cages raising rainbow trout (~250 g) in the Los Lagos Region suffered a disease outbreak. In total, 17,554 fish died (3.5%–4.8% accumulate...
