Antigen Sequences for TBRF Borrelia Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing Tick-Borne Relapsing Fever (TBRF) are delayed, insensitive, and lack specificity due to the need for lengthy blood culture processes, resulting in incomplete identification of Borrelia species, which complicates timely and accurate diagnosis.
Innovation Solution
Development of antigen-specific amino acid sequences for TBRF Borrelia species, used in assays such as Immunoblots and ELISA, to quickly and accurately identify specific Borrelia species in patient samples, enhancing sensitivity and specificity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If blood culture processes are used for TBRF diagnosis, then identification of Borrelia species can be achieved, but assay time is excessively long and sensitivity is insufficient
Solution Approach 1:
The patent extracts and identifies specific amino acid sequences from Borrelia proteins that are unique to TBRF species. By focusing on these specific antigenic sequences rather than performing comprehensive blood cultures, the method achieves rapid and accurate detection of TBRF without requiring lengthy culture processes
Solution Approach 2:
The patent changes the diagnostic parameter from general blood culture to specific amino acid sequence detection. This parameter change enables the use of immunological assays with known sequences, dramatically reducing assay time while maintaining or improving diagnostic accuracy
2Adaptability or versatility
If comprehensive testing for all Borrelia species is performed, then diagnostic coverage is improved, but assay complexity increases
Solution Approach 1:
The patent segments the broad category of Borrelia species into distinct groups with unique amino acid sequence signatures. By designing assays targeting specific sequences unique to TBRF species, the method achieves comprehensive TBRF coverage while avoiding the complexity of testing for all Borrelia species
Solution Approach 2:
The identified amino acid sequences serve as universal markers for specific TBRF species. A single assay using these sequences can detect multiple TBRF species simultaneously, providing comprehensive diagnostic coverage without requiring separate tests for each species
3Ease of operation
If standard blood smear identification is used, then diagnostic process is simple, but sensitivity is only 70% and specificity is insufficient
Solution Approach 1:
The patent introduces specific amino acid sequences as intermediary targets between the complex blood smear examination and the final diagnosis. These sequences serve as reliable mediators that antibodies can specifically recognize, enabling simple immunological assays to achieve high sensitivity and specificity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The use of these amino acid sequences significantly reduces assay time and improves diagnostic accuracy, enabling faster and more reliable detection of TBRF Borrelia species, aiding in effective treatment and eradication of rodent hosts.
Implementation Method 1
The present invention provides antigen-specific amino acid sequences for TBRF Borrelia specific species. These novel amino acid sequences are used in assays to identify TBRF specific Borrelia in samples from subjects suspected of having TBRF.
Implementation Method 2
identification of the Borrelia species can aid in identifying the host rodent for eradication. Currently, the standard for identification is by identification of TBRF spirochetes in blood smears of a subject presenting symptoms consistent with TBRF.
