Enhancement of goldfish virus type 2 replication by 1- naphthol, the major hydrolysis product of the pesticide carbaryl.
The major hydrolysis product of the pesticide carbaryl, 1-naphthol, enhanced the replication of goldfish virus type 2 in piscine cell culture at concentrations below any detectable cytotoxicity. Enhancement indices of 2.3, 3.7, and 7.1 were observed at 1, 5, and 10 ppm (mul/liter), respectively. Replication at 0.5 ppm was equivalent to that of controls.
