Bartonellosis

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Zoonoses

Background:

• Bartonella species are fastidious bacteria found in mammalian blood, transmitted via vectors, scratches, or bites.
• Medically significant bartonelloses include Carrión's disease, trench fever, cat-scratch disease, bacillary angiomatosis, and peliosis hepatis.
• Bartonella are recognized as emerging human pathogens with expanding geographic distribution and increasing recognition in susceptible populations.

Purpose of the Study:

• To discuss the clinical manifestations, differential diagnosis, laboratory diagnosis, and treatment of Bartonella-associated diseases.
• To highlight Bartonella species as emerging human pathogens.
• To provide an overview of medically important bartonelloses.

Main Methods:

• Literature review and synthesis of existing knowledge on Bartonella spp. and associated diseases.
• Discussion of clinical presentations, diagnostic approaches, and therapeutic strategies.
• Analysis of epidemiological patterns and emerging trends in Bartonella infections.

Main Results:

• Bartonelloses manifest diversely, from Carrión's disease (Oroya fever/verruga peruana) to cat-scratch disease and trench fever.
• Emerging geographic sites for Carrión's disease are noted.
• Bartonella infections are increasingly recognized in immunocompromised individuals, such as those with HIV.

Conclusions:

• Bartonella species represent a significant and growing threat in human and veterinary medicine.
• Comprehensive understanding of clinical features, diagnostics, and treatment is crucial for managing bartonelloses.
• Continued surveillance and research are necessary to address the expanding impact of these emerging pathogens.
