Perspective Chapter: Zoonosis – Brucellosis a Clinically Relevant Bacterial Disease

Abstract

In 2020–2022, infectious diseases were the major causes of infection and death globally. Many viral and bacterial diseases are starting to emerge/reemerge frequently. The zoonotic infections were reported to be dominant in a few decades. Now the holistic one-health approach is the need of the hour to tackle the emerging and reemerging pathogens by extensive and heedless use of antimicrobials, lack of novel antimicrobials, and unavailability of appropriate vaccines increased the severity of pathogens. Brucellosis is a well-known zoonotic disease also called undulant fever, Malta fever, Mediterranean fever, etc. Many components of the genus Brucella will be discussed in this chapter, namely pathogenesis, genes/proteins responsible for diseases in animal and humans, available treatment options, drug resistance phenomenon, etc.
