title: Anthelmintic efficacy of Santalum album (Santalaceae) against monogenean infections in goldfish.
abstract: Dactylogyrus spp. and Gyrodactylus spp. are helminth ectoparasites that are a significant threat to the aquaculture industry. Existing treatments could cause the threats of anthelmintic resistance, risk of residues, environmental contamination, and toxicity to fish. Importantly, there is no report on a treatment against these two parasites. This study explored the possibility of using the extracts of Santalum album to treat Dactylogyrus sp. and Gyrodactylus sp. infections in goldfish. Results showed that among the four extracts (chloroform, methanol, ethyl acetate, and water) of S. album, the chloroform extract is the most effective and 40 mg/L is a safe and the lowest effective dosage. In addition, we found that Gyrodactylus elegans is more sensitive than Dactylogyrus intermedius when exposed to the extract of the medicinal plant. Finally, it is substantiated that bath treatment with long duration and multiple administrations could eliminate a greater proportion of monogenean infections. These findings show the potential for the development of effective and safe therapy to treat Dactylogyrus sp. and Gyrodactylus sp. infections of fishes.
