| melaleuca alternifolia anthelmintic activity in gerbils experimentally infected by haemonchus contortus. | gastrointestinal parasites are one of the biggest health problems faced in sheep, mainly due to their pathogenicity and resistance to drugs used to control these parasites. thus, the following study aimed to assess the anthelmintic efficacy of melaleuca alternifolia against haemonchus contortus in gerbils (meriones unguiculatus) experimentally infected. three treatments were tested: m. alternifolia essential oil, popularly known as tea tree oil (tto), a solid lipid nanocarrier made with essentia ... | 2016 | 27646626 |
| in vitro and ex vivo activity of melaleuca alternifolia against protoscoleces of echinococcus ortleppi. | cystic echinococcosis is a zoonotic disease of difficult diagnosis and treatment. the use of protoscolicidal agents in procedures is of utmost importance for treatment success. this study was aimed at analysing the in vitro and ex vivo activity of melaleuca alternifolia oil (tea tree oil - tto), its nanoemulsion formulation (ne-tto) and its major component (terpinen-4-ol) against echinococcus ortleppi protoscoleces obtained from cattle. concentrations of 2·5, 5 and 10 mg ml-1 of tto, 10 mg ml-1 ... | 2017 | 27762176 |
| insecticidal activity of melaleuca alternifolia essential oil and rna-seq analysis of sitophilus zeamais transcriptome in response to oil fumigation. | the cereal weevil, sitophilus zeamais is one of the most destructive pests of stored cereals worldwide. frequent use of fumigants for managing stored-product insects has led to the development of resistance in insects. essential oils from aromatic plants including the tea oil plant, melaleuca alternifolia may provide environmentally friendly alternatives to currently used pest control agents. however, little is known about molecular events involved in stored-product insects in response to plant ... | 2016 | 27936192 |
| melaleuca alternifolia essential oil enhances the non-specific immune system and prevents oxidative damage in rhamdia quelen experimentally infected by aeromonas hydrophila: effects on cholinergic and purinergic systems in liver tissue. | the aim of this study was to evaluate the effects of m. alternifolia essential oil used to treat silver catfish (rhamdia quelen) experimentally infected by aeromonas hydrophila on oxidative stress variables, and for the first time, on hepatic enzymes of the cholinergic and adenosinergic systems. for that, fish were divided into six groups (a-f), each containing seven animals. groups a, b and c were composed of uninfected animals, while animals in groups d, e and f were intramuscularly inoculated ... | 2017 | 27988310 |
| in vitro effects of melaleuca alternifolia essential oil on growth and production of volatile sulphur compounds by oral bacteria. | halitosis can be caused by microorganisms that produce volatile sulphur compounds (vscs), which colonize the surface of the tongue and subgingival sites. studies have reported that the use of natural products can reduce the bacterial load and, consequently, the development of halitosis. the aim of this study was to evaluate the antimicrobial activity of the essential oil of melaleuca alternifolia on the growth and volatile sulphur compound (vsc) production of oral bacteria compared with chlorhex ... | 2017 | 28076463 |
| fungal planet description sheets: 469-557. | novel species of fungi described in this study include those from various countries as follows: australia: apiognomonia lasiopetali on lasiopetalum sp., blastacervulus eucalyptorum on eucalyptus adesmophloia, bullanockia australis (incl. bullanockia gen. nov.) on kingia australis, caliciopsis eucalypti on eucalyptus marginata, celerioriella petrophiles on petrophile teretifolia, coleophoma xanthosiae on xanthosia rotundifolia, coniothyrium hakeae on hakea sp., diatrypella banksiae on banksia for ... | 2016 | 28232766 |
