Pathogenic are spirochetes that cause leptospirosis, a worldwide zoonotic disease. Leptospirosis affects humans and animals, with approximately 1 million human infections and 60,000 deaths per year. The diversity of leptospiral strains and serovars allied to the fact that pathogenesis is not yet fully understood, make the development of an effective vaccine against leptospirosis a challenge.

Article Synopsis
  • The study focuses on combating drug-resistant Campylobacter bacteria found in poultry intestines by using nanotechnology to enhance essential oils' effectiveness.
  • Essential oils like cinnamon, lemongrass, clove, geranium, and oregano showed strong anti-Campylobacter activity, with the capacity to inhibit bacterial growth at low concentrations.
  • Among the developed nanostructured lipid carriers, geranium EO demonstrated the best balance of safety and efficacy for controlling multidrug-resistant bacterial strains.

Epilepsy is a neurological disease with no defined cause, characterized by recurrent epileptic seizures. These occur due to the dysregulation of excitatory and inhibitory neurotransmitters in the central nervous system (CNS). Psychopharmaceuticals have undesirable side effects; many patients require more than one pharmacotherapy to control crises.

Tetrahydrolinalool (THL) is an acyclic monoterpene alcohol, produced during linalol metabolism and also a constituent of essential oils. As described in the literature, many monoterpenes present anticonvulsant properties, and thus we became interested in evaluating the anticonvulsant activity of Tetrahydrolinalool using in mice model as well as in silico approaches. Our results demonstrated that THL increased latency to seizure onset and also reduced the mortality, in picrotoxin induced seizure tests.
