Zoonotic Bridge: Unraveling the Role of Wild Birds in Spreading the Bacterial Pathogenic Diseases
Main Article Content
Abstract
While wild birds contribute significantly to our ecosystem, they also act as carriers for various zoonotic diseases affecting humans. These diseases are often transmitted through international and local migrations, direct contact, and water sources, as well as through droppings and the excretion of spores in their feces. Over time, they present significant risks to the health of humans and animals by serving as carriers and hosts for new strains of pathogens. This review emphasizes the significant zoonotic diseases caused by birds, which include bacterial infections. These pose substantial health risks to both humans and animals. The review delves into their epidemiology and clinical manifestations. Of utmost significance, it underscores the pivotal function of birds as both distributors and reservoirs of potentially significant zoonotic diseases.
