Development and evaluation of three multienzyme isothermal rapid amplification assays for fowl adenovirus serotype 4.
Fowl adenovirus serotype 4 (FAdV-4) is the main causative agent of hydropericardium hepatitis syndrome (HHS), which has resulted in huge economic losses to the poultry industry in recent years. Hence, a rapid and simple visual detection method is needed for identification of FAdV-4. In this study, three multienzyme isothermal rapid amplification (MIRA) assays, basic MIRA, MIRA-qPCR and MIRA-LFD were developed for detection of FAdV-4. The amplification primers and reaction conditions were optimized, and the specificity and sensitivity of the assays were evaluated. The MIRA assays were specific for FAdV-4 with no cross-reaction with novel goose astrovirus, H9 subtype avian influenza virus, duck enteritis virus, Muscovy duck reovirus, or duck circovirus. The basic MIRA assay required only one primer pair and the reaction can be completed within 30 min at 36 °C. The MIRA-qPCR and MIRA-LFD assays were completed in 20 min with a minimum detection limit of 1 × 101 copies/μL and 1 × 102 copies/μL, respectively. The results of the MIRA-LFD assay can be observed directly with the naked eye, omitting the need for specialized instruments. The positive rate of three proposed MIRA assays were consistent with that of the conventional PCR assay. The MIRA assays are simple, rapid, and effective diagnostic tools for field detection of FAdV-4.
期刊介绍:
First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers.
An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
