North America is leading on research funding, number of clinical trials and awareness of rare diseases. Bartonella species have been increasingly recognized in the United States as the cause of cat scratch disease (CSD) and other infections associated with exposure to pets, due to increased diagnostic vigilance and pet ownership.
Hospitals and academic research sites are working to create more definitive protocols for treating both acute and chronic cases. Regional growth has also been sustained by awareness campaigns and CDC guidance.
Bartonellosis is relatively obscure in Europe, but the public health systems of Germany, France, and Italy are witnessing a surge in the surveillance of zoonotic diseases. Growth is being propelled by closer integration of animal and human health systems under the One Health umbrella. Inpatient and outpatient use of specialized antibiotics and adjuvant immune therapies is rising.
Asia-Pacific will be the fastest-growing region, driven by the prevalence of vector-borne diseases in these countries and expanding access to diagnostics. Countries including India, Thailand and the Philippines are building out infectious disease infrastructure, while an uptick in involvement from NGOs is helping in rural and underserved areas. Targeted field studies report cases of Carrion’s disease and related Bartonella bacilliformis infections.
Low awareness, misdiagnosis, and limited treatment protocols hinder market expansion.
Bartonellosis remains largely underdiagnosed despite increasing surveillance until now owing to its nonspecific manifestations, and to the absence of standardized clinical guidelines. The scarcity of the disease also means very few pharmaceutical companies make R&D in this field a top priority. In remote and underserved areas, access to timely diagnosis and treatment is problematic. Bartonella strains can also show antibiotic resistance that may impact treatment.
Emerging diagnostics, research incentives, and endemic region focus support market growth.
This is where rapid point-of-care diagnostics is a great opportunity, particularly in rural endemic areas. Increasing research into neglected tropical diseases, funding for rare pathogens, and improved efforts to collect data can help develop new treatments.
Emerging areas include new antibiotic regimens, immune-modulating therapies and efforts to develop vaccines. NGOs, public health initiatives and international partnerships are also working to ensure therapeutic access where they’re needed most.
The bartonellosis therapeutics market consisted of minimal activity between 2020 and 2024, primarily limited to reactive antibiotic treatment in known zoonotic exposures. Meanwhile, the post-COVID global health focus was broadening to include lesser-known vector-borne disease, increasing general awareness.
Improvements in PCR-based diagnostic tools and genomic pathogen surveillance gradually popularized the role of Bartonella infections in clinical practice, especially in immunocompromised patients and pediatric populations.
From 2025 forwards, Therapuetic development will be aimed towards targeted regimens combining antimicrobial therapy with supportive care for long term infections. The focus will be on establishing clinical databases and protocols for analysis of presentation types (neurological, cardiovascular and chronic inflammatory) associated with Bartonella.
Strategies that ensure regional drug access, better training for health care workers, and One Health. based policies will improve capacity to diagnose, treat and prevent disease.
