Abstract
Infectious diseases caused by Streptococcus iniae lead to massive death of fish, compose a serious threat to the global aquaculture industry, and constitute a risk to humans who deal with raw fish. In order to realize the early diagnosis of S. iniae, and control the outbreak and spread of disease, it is of great significance to establish fast, sensitive, and convenient detection methods for S. iniae. In the present study, two methods of real-time MIRA (multienzyme isothermal rapid amplification, MIRA) and MIRA-LFD (combining MIRA with lateral flow dipsticks (LFD)) for the simA gene of S. iniae were established, which could complete amplification at a constant temperature of 42 °C within 20 min. Real-time MIRA and MIRA-LFD assays showed high sensitivity (97 fg/μL or 7.6 × 102 CFU/mL), which were consistent with the sensitivity of real-time PCR and 10 times higher than that of PCR with strong specificity, repeatability simplicity, and rapidity for S. iniae originating from Trachinotus ovatus. In summary, real-time MIRA and MIRA-LFD provide effective ways for early diagnosis of S. iniae in aquaculture, especially for units in poor conditions.

Abstract
A rapid and accurate diagnosis of brucellosis is required to reduce and prevent the spread of disease among animals and the risk of transfer to humans. In this study, a Brucella abortus-specific (Ba) LAMP assay was developed, that had six primers designed from the BruAb2_0168 region of chromosome I. The specificity of this LAMP assay was confirmed with Brucella reference strains, B. abortus vaccine strains, B. abortus isolates and phylogenetically or serologically related strains. The detection limit of target DNA was up to 20 fg/μl within 60 min. The sensitivity of the new LAMP assay was equal to or slightly higher than other PCR based assays. Moreover, this Ba-LAMP assay could specifically amplify all B. abortus biovars compared to previous PCR assays. To our knowledge, this is the first report of specific detection of B. abortus using a LAMP assay. The Ba-LAMP assay can offer a rapid, sensitive and accurate diagnosis of bovine brucellosis in the field.

Abstract
Loop-mediated isothermal amplification (LAMP) is an outstanding DNA amplification procedure, in which the reaction can accumulate 10(9) copies from less than 10 copies of input template within an hour. While the amplification reaction is extremely powerful, the quantitative detection of LAMP products is still analytically difficult. Besides, the type of targets that LAMP can detect is also less, which to some extent limited the application of LAMP. In this study, we are reporting for the first time an efficient and accurate detection system which employs the integration of LAMP, aptamer and the electrochemical method for the sensitive detection of Ochratoxin A (OTA). Aptamers were designed as the forward outer primer to trigger the LAMP reaction, and then the LAMP amplification products were combined with a redox active molecule methylene blue (MB) and analyzed by an electrode using differential pulse voltammograms (DPV). As the reaction progresses, the MB intercalated into double-stranded regions of LAMP amplicons reduces the free MB concentration. Hence, the peak current of reaction mixture decreased with the amplification because of the slow diffusion of MB-amplified DNA complex to the electrode surface. The peak height of the current was related to the input amount of the aptamers, providing a ready means to detection the concentration of OTA. With such design, the proposed assay showed a good linear relationship within the range of 0.001-50 nM with a detection limit of 0.3 pM (defined as S/N = 3) for OTA.

Abstract
Many species of fungi can cause disease in plants, animals and humans. Accurate and robust detection and quantification of fungi is essential for diagnosis, modeling and surveillance. Also direct detection of fungi enables a deeper understanding of natural microbial communities, particularly as a great many fungi are difficult or impossible to cultivate. In the last decade, effective amplification platforms, probe development and various quantitative PCR technologies have revolutionized research on fungal detection and identification. Examples of the latest technology in fungal detection and differentiation are discussed here.
