Antibody-Based Tapeworm Coproantigen Detection Kit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing parasitic worm infections, particularly tapeworms, are time-consuming, require specialized equipment, and are highly dependent on operator skill, often leading to missed diagnoses due to intermittent egg excretion and the need for complex stool handling.
Innovation Solution
Development of antibodies that specifically bind to tapeworm coproantigens, allowing for the detection and differentiation of tapeworm species through immunoassays, which can be used in devices and kits to identify tapeworms in fecal samples before egg or proglottid appearance, and distinguish between different worm types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microscopic examination of fecal samples is used for tapeworm diagnosis, then detection capability is provided, but the method is time-consuming and requires specialized equipment and operator skill
Solution Approach 1:
The patent replaces the mechanical microscopic examination system with an immunoassay system using antibodies that specifically bind to tapeworm coproantigens. This substitution eliminates the need for specialized microscopy equipment and extensive operator training, while maintaining or improving detection reliability through antibody-specific recognition of tapeworm antigens in fecal samples
Solution Approach 2:
The patent introduces antibodies as intermediary molecules that mediate between the tapeworm coproantigens in the sample and the detection system. These antibodies specifically bind to tapeworm antigens, enabling detection without direct microscopic visualization, thereby simplifying the diagnostic process while preserving detection capability
2Reliability
If microscopic methods are used to detect tapeworm eggs or proglottids, then detection is possible, but accuracy is highly dependent on operator skill and expertise
Solution Approach 1:
The patent replaces operator-dependent microscopic examination with an antibody-based immunoassay system. The antibodies automatically recognize and bind to tapeworm coproantigens, eliminating the need for operator interpretation skills while maintaining high detection accuracy through specific antigen-antibody interactions
Solution Approach 2:
The immunoassay system performs self-detection through the inherent specificity of antibody-antigen binding. The antibodies automatically identify and bind to tapeworm antigens without requiring operator intervention or interpretation, making the test easy to perform while maintaining high accuracy
3Reliability
If complex stool handling procedures are used for fecal testing, then processing completeness is improved, but the number of steps increases and contact between operator and test material increases
Solution Approach 1:
The patent extracts and detects tapeworm coproantigens directly from fecal samples using antibodies, eliminating the need for complex processing steps such as concentration, differentiation, and identification. The immunoassay directly detects antigen presence without requiring complete stool processing, reducing both time and operator exposure
Solution Approach 2:
The immunoassay method skips intermediate processing steps required by traditional microscopy, such as stool concentration, smear preparation, and microscopic examination. The antibody-based detection rapidly identifies tapeworm antigens in the original sample, significantly reducing processing time and steps

AI summary
Methods, devices, kits and compositions for detecting the presence or absence of one or more tapeworm coproantigens in a sample are disclosed herein. The methods, devices, kits and compositions of the present invention may be used to confirm the presence or absence of tapeworm in a fecal sample from a mammal and may also be able to distinguish between different tapeworm species and in the presence of one or more infections with helminths (such as roundworm, hookworm, whipworm and heartworm), Giardia and parvovirus. Confirmation of the presence or absence of tapeworm in the mammal may be made, for example, for the purpose of selecting an optimal course of treating the mammal and/or for the purpose of determining whether the mammal has been rid of the infection after treatment has been initiated.
