Abstract: | Tetrahymena infection has become the most problematic parasitic disease of the guppy Poecilia reticulata in Southeast Asia. Tetrahymena corlissi was isolated from guppies with a fungal infection in Thailand, and the fungus was identified as Achlya bisexualis. Male and female guppies were artificially infected with both organisms. The results showed that guppies could easily be artificially infected with a culture of Tetrahymena corlissi and that female guppies were more sensitive than male guppies. Achlya bisexualis infection was shown to be a secondary infection after the Tetrahymena infection. Received: April 29, 2001 / Accepted: September 6, 2001 |
