Veterinary phytotherapy in Algeria: Pistacia lentiscus as an antimicrobial model / Fitoterapia veterinária na Argélia: emprego da Pistacia lentiscus como um modelo antimicrobiano

Currently, the use of alternative medicine is necessary, even in animals. Our study focused on the valorisation of the use of herbal products in Algerian veterinary medicine. This study is based on a 6-month exploratory survey of 257 private practicing veterinarians, followed by a study of the bacteriological activity of the essential oil of the Pistacia lentiscus plant. The survey results generally indicate that private veterinarians support phytotherapy as an alternative to conventional drugs in several areas and species. Also, the results of research conducted on the antibacterial activity of Pistacia lentiscusessential oil show that it inactivates 50% of the bacterial strains. This confirms the well-defined role of this medicinal plant used as an alternative in veterinary medicine.(AU)

Na atualidade o emprego da medicina alternativa é uma realidade, inclusive para os animais; este trabalho visa a valorização do emprego de produtos fitoterápicos na medicina veterinária da Argélia. O presente estudo baseou-se em um levantamento realizado durante seis meses com 257 médicos veterinários do setor privado, seguido de uma investigação da atividade bacteriológica do óleo essencial da planta Pistacia lentiscus. Os resultados do levantamento indicaram que esses profissionais aceitam o emprego da fitoterapia como uma alternativa para as drogas de uso convencional em diferentes áreas e espécies de animais. A avaliação da atividade antibacteriana do óleo essencial da Pistacia lentiscusrevelou que 50% das estirpes bacterianas empregadas foram inativadas após seu uso, o que confirmou a possibilidade do emprego desta planta medicinal como uma alternativa para a medicina veterinária.(AU)

[Application of edible coatings incorporated avishan-e shirazi [zataria multiflora] alcoholic extract for inhibition of aspergillus flavus growth on the pistachio kernel]

Antimicrobial packaging is a form of active packaging that could extend the shelf-life of foods and provides microbial safety for consumers. In order to control undesirable microorganisms on food surfaces, volatile and non-volatile antimicrobial agents can be incorporated into polymers. Incorporation of essential oils and other antifungal agents in edible films composition is an antimicrobial packaging that able to inhibit fungal growth on the pistachio and aflatoxins production. The antifungal activity of Avishan-e Shirazi [Zataria multifora] extracts against Aspergillus flavus in whey protein concentrate-based coating on pistachio kernels was investigated. The antifungal effect of Avishan-e Shirazi extracts was investigated in culture media by direct method [cup plate method] and application of whey protein concentrate [WPC] films as discs [disc deffusion method] incorporated with different concentrations of extracts. In order to evaluate the antifungal effect of extract in pistachio kernels coated with different concentrations of extract inoculated with a culture media discs contain 9-day-old growing A. flavus colony and the growth rate of inoculated discs were measured during 1 week. In experimental condition, minimal inhibition concentration was achieved by 90ppm of ahcoholic extract [30 percent concentration]. The results also showed that WPC coating incorporated with 2500ppm of Zataria multiflora extracts on pistachio kernels inhibited A. flavus growth totally. Regarding to application of importance of contamination with toxigenic fungi in pistachio kernel is suggested the application of Avishan-e Shirazi extract incorporated in edible coatings for toxigenic fungi growth and toxin production in foods
