Selective Essential Oils from Spice or Culinary Herbs Have High Activity against Stationary Phase and Biofilm Borrelia burgdorferi

Feng J, Zhang S, Shi W, Zubcevik N, Miklossy J, Zhang Y Frontiers in Medicine, 2017 ABSTRACT: Although the majority of patients with acute Lyme disease can be cured with the standard 2-4 week antibiotic treatment, about 10-20% of patients continue suffering from chronic symptoms described as posttreatment Lyme disease syndrome. While the cause for this… Read more »

Combined Toxicity of Three Essential Oils Against Aedes aegypti (Diptera: Culicidae) Larvae

Muturi EJ, Ramirez JL, Doll KM, Bowman MJ Journal of Medical Entomology, 2017 ABSTRACT: Essential oils are potential alternatives to synthetic insecticides because they have low mammalian toxicity, degrade rapidly in the environment, and possess complex mixtures of bioactive constituents with multi-modal activity against the target insect populations. Twenty-one essential oils were initially screened for their toxicity against… Read more »

Carvacrol-rich oregano oil and thymol-rich thyme red oil inhibit biofilm formation and the virulence of uropathogenic Escherichia coli

Lee JH, Kim YG, Lee J Journal of Applied Microbiology, 2017 AIMS: Urinary tract infections are caused primarily by uropathogenic Escherichia coli (UPEC), and indwelling catheters are usually colonized by UPEC biofilms tolerant to common antibiotics. Hence, UPEC biofilms pose a substantial challenge, and there is an urgent need for effective control strategies. METHODS AND… Read more »
