What is the major cause of pathogenic diseases in exotic animals?

The major cause of pathogenic diseases in exotic animals is often linked to stress factors, such as captivity, habitat loss, and inadequate care, which can compromise their immune systems. Additionally, exposure to pathogens through human interaction, contaminated environments, and the introduction of non-native species can exacerbate disease susceptibility. Other contributing factors include improper nutrition and lack of veterinary care, which hinder the animals' ability to fend off infections. Overall, the interplay of these elements creates a heightened risk for disease in exotic species.
