Chicken chaphamaparvovirus (CkChpV) is a newly emerging pathogen that is currently prevalent in chickens with diarrhea symptoms. To diagnose CkChpV more conveniently and rapidly, this study established a multienzyme isothermal rapid amplification (MIRA) assay, with a reaction time of only 15 min and optimal reaction temperature of 38°C. In combination with the lateral flow dipstick assay, the CkChpV-MIRA assay can be completed within 20 min. We revealed that the detection limit of the MIRA assay using standard plasmids as templates was as low as 21.3 copies, and its sensitivity was 100 times higher than that of nested PCR. Moreover, the designed primer set and probe could only detect CkChpV specifically, and there was no cross reaction with avian nephritis virus, rotavirus, chicken parvovirus virus, Newcastle disease virus, and infectious bronchitis virus, which may cause diarrhea. These findings demonstrated that the CkChpV-MIRA assay established in this study is convenient, sensitive, and specific and does not require sophisticated equipment. It is more suitable for the detection of CkChpV in clinical samples.

is a widespread foodborne pathogen that can cause food poisoning when present in food at certain levels. Ingesting contaminated food may lead to symptoms such as abdominal pain, diarrhea, and, in severe cases, life-threatening conditions. In this study, a simple and super-fast method for detecting was developed, which combines cellulose filter paper-based DNA extraction, multienzyme isothermal rapid amplification (MIRA), and lateral flow dipstick (LFD) technology.

Feline chaphamaparvovirus (FeChPV) is a novel parvovirus previously reported in Canadian cats and Chinese dogs with diarrhea in 2019 and 2020, respectively. Herein, we aimed to establish a simple detection method for FeChPV in field clinics. The primers and probes for the multienzyme isothermal rapid amplification and lateral flow dipstick (MIRA-LFD) assay were designed to target the conserved regions of the FeChPV genome and determine the optimal reaction temperature and time.

Hand, foot, and mouth disease (HFMD), caused by enteroviruses, mostly including EV71, CVA6, CVA10, and CVA16, is an acute infectious disease commonly found in children. Due to no approved antiviral therapies and available vaccines, except for EV71, developing accurate diagnostic methods of HFMD is essential for controlling its spread and mitigating its impact on public health. Here, we create a MIRA-HEV-PAND multiple nucleic acid typing method that utilizes Ago to identify enterovirus type A pathogens (EV71, CVA6, CVA10, and CVA16) and universal type EVU.

Persistent infection with high-risk human papillomavirus (HR-HPV) is the principal etiological factor of cervical cancer. Considering the gradual progression of cervical cancer, the early, rapid, sensitive, and specific identification of HPV, particularly HR-HPV types, is crucial in halting the advancement of the illness. Here, we established a rapid, highly sensitive, and specific HR-HPV detection platform, leveraging the CRISPR/Cas12a assay in conjunction with multienzyme isothermal rapid amplification.

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.
