Detection and Species Identification of Malaria Parasites by Isothermal tHDA Amplification Directly from Human Blood without Sample Preparation

Loop-mediated isothermal amplification (LAMP) assays for detection of malaria parasites

Identification of Staphylococcus aureus and determination of methicillin resistance directly from positive blood cultures by isothermal amplification and a disposable detection device.

A simple, rapid, and user-friendly procedure has been developed to identify Staphylococcus aureus and determine its methicillin resistance directly from gram-positive cocci in cluster-containing blood culture medium. The specimens were diluted and heated prior to amplification of the nuc and mecA genes with isothermal helicase-dependent amplification. Amplicons were detected using a disposable ...

Rapid Point-of-Care Isothermal Amplification Assay for the Detection of Malaria without Nucleic Acid Purification

Malaria remains one of the most prevalent infectious diseases and results in significant mortality. Isothermal amplification (loop-mediated isothermal amplification) is used to detect malarial DNA at levels of ~1 parasite/µL blood in ≤30 minutes without the isolation of parasite nucleic acid from subject's blood or saliva. The technique targets the mitochondrial cytochrome oxidase subunit 1 gen...

Colorimetric detection of human papilloma virus by double isothermal amplification.

We developed a polymerase reaction free, low-cost and sensitive assay for the colorimetric detection of Human Papilloma Virus (HPV), based on the use of a smart design exploiting magnetic microbeads, chimeric RNA/DNAzyme oligonucleotides, and double signal amplification. This method allows obtaining a fast response with a detection limit of 10 pM, avoiding the amplification of the target via tr...

Rolling Circle Amplification (RCA): an approach for quick detection and identification of fungal species

Conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. These tests often need several days or weeks to complete and are frequentlyunspecific. Molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. The Rolling CircleAmplification app...
