Effect of pre-supplementation with crude extracts on body weight and consequence responses of leukocytes and immune organs in fancy carp following inoculation with .

Aim: The present study aimed at highlighting the effects of oyster mushroom (), as a dietary supplement on growth performance, differential leukocytes population, and histological changes of melanomacrophage centers (MMCs) in spleen and kidney of fancy carp on bacterial infection.

Materials And Methods: A total of 60 fancy carp were allocated into four groups according to feed formulations including; (1) basal diet with 2% crude extract of , (2) basal diet with 2% b-glucan, whereas Group 3, and Group 4 were positive and negative control, which were fed only basal diet. Diets were provided for 30 days, thereafter, fish of Group 1 to Group 3 were intraperitoneally injected with (1.

Opisthorchis viverrini: analysis of the sperm-specific rhophilin associated tail protein 1-like.

Concurrent deficiency of rhophilin associated tail protein (ROPN1) and ROPN1-like (ROPN1L) in mice causes structural abnormalities and immotility of sperm and thereby infertility. In the present research, ROPN1L of the human liver fluke Opisthorchis viverrini was molecularly characterized and showed unexpected potential as a diagnostic tool. ROPN1L transcripts were detected in 2-week-old juveniles by RT-PCR.
