[Antibody neutralization test in brucellosis].

Area of Science:

• Veterinary Immunology
• Bacteriology
• Diagnostic Microbiology

Background:

• Brucellosis remains a significant zoonotic disease globally.
• Accurate and sensitive diagnostic tools are crucial for controlling brucellosis outbreaks.
• Current diagnostic methods for brucellosis have limitations in sensitivity or specificity.

Purpose of the Study:

• To evaluate a novel antibody neutralization test for brucellosis detection.
• To assess the specificity and sensitivity of the test using erythrocytes sensitized with lipopolysaccharide.
• To determine the utility of this test in identifying brucellae and brucellosis antigen in diverse sample types.

Main Methods:

• Development of an antibody neutralization test employing erythrocytes sensitized with lipopolysaccharide.
• Testing the assay's performance on pathological materials, food samples, and environmental swabs.
• Comparative analysis of test results against established brucellosis diagnostic standards.

Main Results:

• The developed antibody neutralization test exhibited high specificity in detecting brucellosis.
• The test demonstrated significant sensitivity for identifying brucellae and brucellosis antigen.
• Successful detection of the antigen was achieved across pathological, food, and environmental samples.

Conclusions:

• The antibody neutralization test using lipopolysaccharide-sensitized erythrocytes is a highly specific and sensitive method for brucellosis diagnosis.
• This assay shows promise for the reliable detection of brucellosis in clinical, food, and environmental settings.
• The test offers a valuable tool for brucellosis surveillance and control programs.
