A loop-mediated isothermal amplification (LAMP) assay for the rapid detection of cytomegalovirus (CMV) was developed and evaluated. The LAMP assay specifically amplified only CMV DNA, and no cross-reactivity with the DNA of herpes simplex virus type 1, varicella-zoster virus, adenovirus, Aspergillus flavus, or Staphylococcus aureus was observed. The sequences of the LAMP assay-positive CMV prod...

TO THE EDITOR—Goyal et al [1] provide additional useful commentary on the article by Patel et al, which investigates the usefulness of real-time fluorescence loop-mediated isothermal amplification (LAMP) for point-of-care testing for malaria [2, 3]. We agree on the issues raised regarding laboratory infrastructure requirements and precautions necessary to prevent contamination. However, specifi...

Here we report a rapid and sensitive method (using loop-mediated isothermal amplification [LAMP]) for the diagnosis of edwardsiellosis, a fish disease caused by Edwardsiella tarda, in Japanese flounder. A set of four primers was designed, and conditions for the detection were optimized for the detection of E. tarda in 45 min at 65 degrees C. No amplification of the target hemolysin gene was det...

Background and Aim: Sporothrix schenckii is the causative agent of sporotrichosis, which most commonly causes lymphocutaneous infections in immunocompromised hosts. This pathogen infects dogs, cats, cattle, buffaloes can potentially infect humans. Diagnosis by fungal culture lengthy, although there are several clinical diagnoses molecular methods, these complicated time-consuming for veterinari...

BACKGROUND Aberrant DNA methylation of gene promoters and the associated silencing of tumor suppressor genes are recognized as mechanisms contributing to tumor development. Therefore, detection of promoter hypermethylation is becoming important for diagnosis, prognosis, and aiding the design of cancer therapies. We describe a novel isothermal method for the detection of DNA hypermethylation. ...

Loop-mediated isothermal amplification (LAMP) constitutes a potentially valuable diagnostic tool for rapid diagnosis of contagious diseases. In this study, we developed a novel LAMP method (seM-LAMP) to detect the seM gene of Streptococcus equi subsp. equi (S. equi), the causative agent of strangles in equids. The seM-LAMP successfully amplified the target sequence of the seM gene at 63°C withi...

In this study, a loop-mediated isothermal amplification (LAMP) assay was established to detect Toxoplasma gondii DNA in mice infected with T. gondii PRU strain. This LAMP assay was based on the sequence of highly repetitive B1 gene. The detection limit of T. gondii LAMP assay was 1 pg of T. gondii DNA, which was evaluated using 10-fold serially diluted DNA of cultured parasites. The LAMP assay ...

We have evaluated a diagnostic system based on the loop-mediated isothermal amplification (LAMP) assay for the rapid, simple, and sensitive detection of Newcastle disease virus (NDV) directly from culture isolates as well as clinical samples. By using one set of specific primers targeting the fusion protein gene, the LAMP assay rapidly amplified the target gene within 2 h, requiring only a regu...

We improved a loop-mediated isothermal amplification (LAMP) assay permitting sensitive and rapid Mycoplasma bovis detection. A total of 55 bacterial strains were examined in this study, including 33 M. bovis strains, 14 non-M. bovis mycoplasmas and eight non-mycoplasma bacterial strains. M. bovis was successfully detected by the LAMP assay within 60 min without cross-reaction to any other bacte...
