title: Effects of the antimicrobic tiamulin on seven gram-negative bacterial fish pathogens.
abstract: In vitro and in vivo test were carried out with tiamulin and gram-negative bacterial pathogens of fish. Determination of minimum inhibitory concentration for 51 strains of seven species of gram-negative bacterial pathogens showed that only strains of Vibrio anguillarum were sensitive at 1.6-6.25 ppm, while the rest of test strains required 25- greater than 100 ppm. Control of infection was not achieved when tiamulin was fed for 14 days at 5 or 50 mg/kg to rainbow trout (Salmo gairdneri) experimentally infected with Yersinia ruckeri.
