The most medically important species in the family Opisthorchiidae are Clonorchis sinensis, Opisthorchis viverrini, and Opisthorchis felineus,[1] that are causes of the disease clonorchiasis.[1]
Some species are parasites of economically important fish, e.g. Clarias gariepinus.[2]

gollark: > Factoring large numbers is, in general, hard. The Pollard-Brent rho algorithm used by factor is particularly effective for numbers with relatively small factors. If you wish to factor large numbers which do not have small factors (for example, numbers which are the product of two large primes), other methods are far better. Oh bee.
gollark: This is the GNU coreutils one.
gollark: I'll check.

gollark: I'm not really sure what the limits are.
