A review on phytochemical and bacteriophage based therapeutic strategies for the management of Brucellosis
Abstract
Brucellosis, a zoonotic disease, triggers severe inflammation and reproductive complications in both humans and animals. The standard treatment protocol relies on prolonged antibiotic courses, often combining streptomycin and doxycycline, or gentamicin and doxycycline, for a duration of six to eight weeks. However, concerns have arisen regarding the efficacy, with a notable 15% failure rate and frequent relapses. The lack of suitable vaccines and the rise of antimicrobial resistance in Brucella spp., due to prolonged antibiotic use further complicate the issue. This review underscores the pressing issue of antibiotic resistance, prompting an exploration of alternative treatment avenues. Phytochemicals like polyphenols and terpenoid rich essential oils have been reported to possess strong anti-Brucellar activity and function by disrupting cell wall and membrane functions, prevent binding to host cells and internalization and inhibit DNA replication and transcription and enzyme synthesis. Similarly, bacteriophages, have demonstrated promise as diagnostic, therapeutic and biocontrol agents in Brucellosis management. The efficacy of bacteriophage mediated strategies can be enhanced by site specific delivery through nano-encapsulation techniques while engineered phages can be used for diagnosis and modulate immune response in host. These alternative therapies have even been found to stimulate innate immunity in host. However, the precise mechanisms through which these treatments…
