Antimycotic activity againstSaprolegnia ferax of extracts ofArtemisia verlotorum andSantolina etrusca

Abstract

Methanol and aqueous extracts of Artemisia verlotorum and Santolina etrusca were screened in vitro against Saprolegnia ferax and for all extracts the MIC were determined. Screening was performed also on two fractions of the aqueous extracts. Copyright © 1999 John Wiley & Sons, Ltd.

In vitro screening for the antifungal activity of some Egyptian plant extracts against the fish pathogen Saprolegnia parasitica

“…is ongoing, the present study was performed to primarily evaluate the anti-Saprolegnia activity of some randomly selected, neglected plants and road-side weeds, for the future possibility of their usage in aquaculture practice, in-line with that, a comparison with randomly selected voucher type herbal remedies was performed. Likewise this study, same plants were previously investigated for a similar purpose (Hussein et al, 2000;Pattnaik, Subramanyam, & Kole, 1996;Pirbalouti, Taheri, Raiesi, Bahrami, & Abdizadeh, 2009;Tampieri et al, 2003), even extracts of other parts of the same plant (Tampieri et al, 2003), and other plants belonging to the same genera were investigated for anti-Saprolegnia activity (Gormez & Diler, 2014;Macchioni, Perrucci, Flamini, Cioni, & Morelli, 1999;Pirbalouti et al, 2009;Soltani et al, 2020;Tampieri et al, 2003).…”

“…Furthermore, inhibition of fish egg mycosis was observed by other extracts (Khosravi, Shokri, Sharifrohani, Mousavi, & Moosavi, 2012;Li & Liu, 2015;Zeng et al, 2019). Other in vitro screening studies showed significant anti-Saprolegnia activity of many extracts (Gormez & Diler, 2014;Hu et al, 2013;Huang et al, 2015;Macchioni, 1999;Mori, Hirose, Hanjavanit, & Hatai, 2002;Rai, Kaushal, & Acharya, 2002;Rai, Soni, & Acharya, 2000;Udomkusonsri, 2007;Yao et al, 2017).…”

Evaluation of the Antifungal Activity of Zataria multiflora , Geranium herbarium, and Eucalyptus camaldolensis Essential Oils on Saprolegnia parasitica– Infected Rainbow Trout ( Oncorhynchus mykiss ) Eggs

“…In controls, malachite green (positive control group) had positive significant differences in comparison with G. herbarium and negative control ( p <0.05), and negative control showed positive significant differences in comparison with Z. multiflora , E. camaldolensis, and malachite green ( p <0.05). Although literature search showed that there is no research about antifungal activity of these tested oils against S. parasitica , some investigators demonstrated the inhibitory effects of different plants on some fungi in the saprolegniaceae such as Artemisia verlotorum, and Santolina etrusca extracts against S. ferax (Macchioni et al ., 1999), Blumea balsamifera, B. mollis, Eupatorium triplinerve, Guizotia abyssynica , and Tagetes erecta essential oils against S. ferax (Rai et al ., 2002) and Alpinia galanga essential oil against S. parasitica , S. diclina , Achlya bisexualis , A. diffusa , and Aphanomyces piscicida (Chukanhom et al ., 2005). Inhibitory effects of essential oils of aegle, ageratum, citronella, eucalyptus, geranium, lemongrass, orange, palmarosa, patchouli, peppermint, and clove against fungal strains isolated from fish eggs were reported by other investigators (Pattnaik et al ., 1996; Keene et al ., 1998) as well.…”

Strategies for Solving the Issue of Malachite Green Residues in Aquatic Products: A Review

“…Te antimycotic activity of several plant essential oils and extracts against Saprolegnia ferax was screened in vitro by an Italian scientifc group. Te results showed that the essential oils of thyme (Tymus vulgaris) and the methanol extract of Artemisia verlotorum displayed suitable activities; their MIC (minimum inhibitory concentration) was 40 ng/mL [137] and 0.25% [138], respectively. After that, more plant essential oils and extracts were screened for their anti-Saprolegnia activities.…”
