Anthelmintic effect of Cymbopogon citratus essential oil and its nanoemulsion on sheep gastrointestinal nematodes.

The anthelmintic resistance stimulated the search for strategies for controlling gastrointestinal nematodes, including the use of free essential oils or its nanoemulsion. This study evaluated the anthelmintic efficacy of Cymbopogon citratus essential oil (CcEO) and C. citratus essential oil nanoemulsion (CcEOn).

Nanocapsules of Sterculia striata acetylated polysaccharide as a potential monomeric amphotericin B delivery matrix.

Stable oil nanocapsules based on acetylated Sterculia striata polysaccharide (ASSP) were produced without the use of a surfactant, and derivatives of ASSP with four different degrees of substitution (DS) were synthesised. The data revealed that only derivatives with high DS were able to produce nanocapsules (NC), which exhibited monomodal size distribution profiles with a Z-average particle size, ζ-potential, and polydispersity index (PDI) that were dependent on ASSP DS and concentration. Nanocapsules were loaded with amphotericin B (AMB) with encapsulation efficiencies (EE%) that were dependent on drug and ASSP concentrations and DS.

Anthelmintic effect of thymol and thymol acetate on sheep gastrointestinal nematodes and their toxicity in mice.

Thymol is a monoterpene and acetylation form of this compound can reduce the toxicity and enhance its biological effects. The objective of this study was to evaluate the effect of thymol and thymol acetate (TA) on egg, larva and adult Haemonchus contortus and the cuticular changes, acute toxicity in mice and the efficacy on sheep gastrointestinal nematodes. In vitro tests results were analyzed by analysis of variance (ANOVA) and followed by comparison with Tukey test or Bonferroni.

In vitro effects of Eucalyptus staigeriana nanoemulsion on Haemonchus contortus and toxicity in rodents.

Strategies for controlling gastrointestinal nematodes have been developed based on the use of numerous alternative methods, including the use of phytotherapy. New formulations of essential oils with anthelmintic activity have been proposed as a means to optimize their biological effects. Thus, the objective of this study was to formulate a nanoemulsion to optimize the nematicide effect of Eucalyptus staigeriana essential oil (EsEO).

In vitro effects of Coriandrum sativum, Tagetes minuta, Alpinia zerumbet and Lantana camara essential oils on Haemonchus contortus.

Phytotherapy can be an alternative for the control of gastrointestinal parasites of small ruminants. This study evaluated the efficacy of Alpinia zerumbet, Coriandrum sativum, Tagetes minuta and Lantana camara essential oils by two in vitro assays on Haemonchus contortus, an egg hatch test (EHT) and larval development test (LDT). No effect was observed for L.

Anthelmintic activity of Eucalyptus staigeriana encapsulated oil on sheep gastrointestinal nematodes.

The anthelmintic activity of Eucalyptus staigeriana essential oil has previously been inferred through both in vitro and in vivo tests. Thus, the encapsulation process generally improves oil stability, promotes controlled release in target organs, reduces dosage, and increases efficacy. The aims of this study were to analyze and encapsulate E.

Activity of chitosan-encapsulated Eucalyptus staigeriana essential oil on Haemonchus contortus.

Phytotherapy has been described as an alternative method for the control of gastrointestinal nematodes in small ruminants. Goal of the encapsulation of essential oils in biopolymer matrices is to optimize the biological effects of these oils. The aim of the present study was to evaluate the in vitro and in vivo anthelmintic activity of encapsulated Eucalyptus staigeriana essential oil (EncEs) on the eggs and larvae of Haemonchus contortus.
