Overview
Brucella abortus infection, also known as brucellosis, is a zoonotic disease primarily affecting livestock but transmissible to humans, causing undulant fever and other systemic symptoms [Not directly covered in provided abstracts].Diagnosis
Clinical symptoms include fever, sweats, arthralgias, and fatigue [Not directly covered in provided abstracts].
Laboratory confirmation involves serological tests such as agglutination tests (e.g., Wright or 2-mercaptoethanol tests) [Not directly covered in provided abstracts].
Blood cultures may be positive during the acute phase but are often negative in chronic cases [Not directly covered in provided abstracts].Management
First-line treatment typically includes a combination of antibiotics: doxycycline and rifampin for at least 4-6 weeks [Not directly covered in provided abstracts].
Additional agents like streptomycin or gentamicin may be added initially for severe cases [Not directly covered in provided abstracts].
Follow-up serological testing is crucial to monitor treatment efficacy [Not directly covered in provided abstracts].Special Populations
Pregnancy: Management strategies in pregnant women require careful consideration due to potential teratogenic effects of certain antibiotics; close monitoring and consultation with infectious disease specialists are advised [Not directly covered in provided abstracts].
Pediatrics: Specific dosing and safety data are limited; treatment should be individualized with pediatric infectious disease consultation [Not directly covered in provided abstracts].
Elderly: No specific guidelines provided; general principles apply with emphasis on monitoring for drug interactions and organ function [Not directly covered in provided abstracts].
Comorbidities: Patients with comorbidities may require adjusted treatment regimens to avoid exacerbating existing conditions; multidisciplinary care is recommended [Not directly covered in provided abstracts].Key Recommendations
Initiate empirical treatment with doxycycline and rifampin for at least 4-6 weeks in confirmed cases of Brucella abortus infection (Evidence: Expert opinion) [Not directly covered in provided abstracts].
Consider adding an aminoglycoside like streptomycin for severe cases during the initial phase of treatment (Evidence: Expert opinion) [Not directly covered in provided abstracts].
Regular serological follow-up is essential to assess treatment response and ensure eradication of the infection (Evidence: Expert opinion) [Not directly covered in provided abstracts].References
