Visual detection of fowl adenovirus serotype 4 via a portable CRISPR/Cas13a-based lateral flow assay.
The widespread occurrence of fowl adenovirus serotype 4 (FAdV-4)-induced hepatitis-hydropericardium syndrome (HHS) has led to significant economic losses for the poultry industry. A sensitive, accurate, and practical FAdV-4 diagnostic approach is urgently required to limit the incidence of the disease. In the present study, a practical method for detecting FAdV-4 was developed using the CRISPR/Cas13a system and recombinase-aided amplification. The approach was based on 37°C isothermal detection with visible results being achieved. The detection limit of the target gene with this approach was only 101 copies/μl, making it very sensitive and specific. Clinical samples fared well when tested with the Cas13a detection method. For identifying FAdV-4, this novel detection approach was found to be sensitive, specific, and effective.RESEARCH HIGHLIGHTS First study using the CRISPR/Cas13a-based lateral flow detection assay for FAdV-4 detection.The results can be observed by the naked eye.The developed assay could provide an alternative tool for detection of FAdV-4 with minimal equipment.
期刊介绍:
Avian Pathology is the official journal of the World Veterinary Poultry Association and, since its first publication in 1972, has been a leading international journal for poultry disease scientists. It publishes material relevant to the entire field of infectious and non-infectious diseases of poultry and other birds. Accepted manuscripts will contribute novel data of interest to an international readership and will add significantly to knowledge and understanding of diseases, old or new. Subject areas include pathology, diagnosis, detection and characterisation of pathogens, infections of possible zoonotic importance, epidemiology, innate and immune responses, vaccines, gene sequences, genetics in relation to disease and physiological and biochemical changes in response to disease. First and subsequent reports of well-recognized diseases within a country are not acceptable unless they also include substantial new information about the disease or pathogen. Manuscripts on wild or pet birds should describe disease or pathogens in a significant number of birds, recognizing/suggesting serious potential impact on that species or that the disease or pathogen is of demonstrable relevance to poultry. Manuscripts on food-borne microorganisms acquired during or after processing, and those that catalogue the occurrence or properties of microorganisms, are unlikely to be considered for publication in the absence of data linking them to avian disease.
