A Comprehensive Review Examination Study of Zoonotic Bacterial Infections: Anthrax and Brucellosis, Epidemiology, Surveillance, Clinical Manifestations, Prevention and Control Strategies

Abstract

The two significant zoonotic bacterial infections that have remained a concern due to the complex dynamics involved in transmission and global prevalence are anthrax and brucellosis. The present paper attempts to address some of the most important zoonotic pathogens, highlighting their epidemiology, clinical manifestations, diagnosis, treatment, and prevention strategies. Anthrax is largely transmitted through direct contact with the infected animals or their products resulting in cutaneous, inhalational, and gastrointestinal forms, all with specific clinical outcomes and approaches for treatment. Similarly, the genus Brucella primarily transmits brucellosis to humans by occupational exposure and consumption of contaminated animal products. Its presentation may be acute, chronic, or in relapse. Diagnosis is made by a combination of serological, molecular, and culture-based techniques, while the treatment focuses on antimicrobial regimens specific to the pathogen. However, this increases the problem of antimicrobial resistance, which makes their effective management challenging, necessitating an integrated approach. Mitigating risks through biosecurity measures, vaccination, public health education, and a One Health approach that includes human, animal, and environmental health, all facilitate prevention and control of an outbreak. Advanced surveillance and diagnostic technologies further support the prompt interventions to contain outbreaks. It then goes on to highlight the importance of interdisciplinarity for decreasing the global burden of zoonotic bacterial diseases.
