RESUMO
Parasitic infections are a major public health concern affecting millions of people universally. This review elaborates on the potential impacts of plants and their bioactive components that have been widely used in the cure of several parasitic infections of poultry. The medicinal importance of natural herbs depends upon their bioactive ingredients, which are originated from crude plants, consequently leading to the specific action on the body. Due to the limited availability of effective drugs and high cost, the development of drug resistance in several harmful parasites and microbes leads to huge economic losses in the poultry industry. This will impose the development of innovative sources for drugs to overwhelm the therapeutic failure. Moreover, the environment-friendly feed additives which can be applied as a substitute to antibiotic growth promoters (AGP) for broilers were proven. The application of natural products with therapeutic characteristics is an ancient practice that is appropriately gaining more acceptance. Globally, it is assessed that some 20,000 species of higher plants are used medicinally, although traditional medicine has a scarcity of knowledge on its efficiency and wellbeing. This review explores the usage of medicinal herbs for parasitic infections, emphasizing the recent knowledge available while detecting the research gaps which may be explored to find the usage of herbal medicines for parasitic infections in poultry. In conclusion, herbal medicines are the effective source of prime components for drug detection and the formation of phytopharmaceuticals in the control of devastating parasitic infections. There is a prerequisite to applying the traditional medicine information in clinical applications via value addition.
RESUMO
The livestock sector is continuously facing problems in controlling parasitic diseases especially Haemonchosis due to emergence of anthelminthic resistance and failure in vaccination control programmes. Therefore, to increase milk and meat production and emerging demand of meat free from drug residues development of new alternative approaches are appealing for prevention and control of Haemonchosis in small ruminants. Among alternatives, plants driven essentials oils have shown promising results in control of Haemonchus contortus infection at various concentrations by different assays including egg hatch assay, larval development assay, larval exsheathment assay and adult motility assay. Essential oils are complex mixtures of various impulsive or volatile compounds which have potential to control Haemonchosis. The current study reviews the therapeutic effects of essential oils of plants against Haemonchus contortus and to be used them against Haemonchus contortus for future perspectives.
El sector ganadero enfrenta continuamente problemas para controlar las enfermedades parasitarias, especialmente la hemoncosis, debido a la aparición de resistencia antihelmíntica y al fracaso en los programas de control de vacunación. Por lo tanto, para aumentar la producción de leche y carne, y la demanda emergente de carne libre de residuos de medicamentos, el desarrollo de nuevos enfoques alternativos es atractivo para la prevención y el control de la hemoncosis en pequeños rumiantes. Entre las alternativas, los aceites esenciales producidos por las plantas han mostrado resultados prometedores en el control de la infección por Haemonchus contortus a diversas concentraciones mediante diferentes ensayos, incluido el análisis de eclosión de huevos, el desarrollo de larvas, el análisis de vaciado de larvas y el ensayo de motilidad en adultos. Los aceites esenciales son mezclas complejas de varios compuestos impulsivos o volátiles que tienen potencial para controlar la hemonchosis. Este estudio revisa los efectos terapéuticos de los aceites esenciales de las plantas contra Haemonchus contortus y evalúa sus perspectivas futuras como agentes para combatir las enfermedades causadas por este parásito.
