Abstract

Owing to rising incidences of antimicrobial resistance against various chemotherapeutic and antimicrobial agents, the treatment of bacterial infections requires special consideration that may otherwise lead to grave prognosis. Simultaneously, evolution of many a Multiple Drug Resistant (MDR) bacterial strains have further aggravated the present situation. In this scenario, scrutinizing for some alternative yet effective antibacterial therapeutics like herbs, nutritional immunomodulators, bacteriophages, avian egge antibodies and others have become need of the day. Herbs have been a valuable source of medication in virtually all cultures and societies worldwide due to their important antimicrobial principles and phytoconstituents and wider therapeutic potentials. As various extracts of herbs and medicinal plants are being reported with antibacterial activities, much effort should be made in their identification, studying biologically active ingredients, efficacy and potency testing and scientific validation for their significant and practical multi-beneficial uses. The present review elaborates the potential role and applications of several herbs in treating bacterial infections and various types of bacterial diseases for safeguarding health of humans and their companion animals. It highlights the salient beneficial applications of traditional herbs and novel phytomedicines, from ancient periods to modern usages. Due emphasis has been given regarding scientific approaches to be followed and future perspectives with a vision to counter the emerging antimicrobial resistance. The review will certainly promote and popularize herbs as alternatives to conventional antimicrobials, particularly in the event of emerging MDR bacterial infections. Global usages of herbs as alternative and complementary medicines to various antimicrobials would lead not only to safeguard health issues and obtain optimum production from animals but will also ensure the public health issues including of food safety concerns viz., antibiotic residual effects in animal products (milk, meat) and zoonotic threats.
