Report Discusses POC Testing and Changing Paradigms

The American Academy of Microbiology has released a new report on the role of the role of point-of-care (POC) and near-patient testing in changing diagnostic paradigms in microbiology. More...

Image: Research shows Zika fever symptoms are often misdiagnosed due to its nonspecific clinical symptoms, so a highly accurate diagnostic assay for Zika virus is especially important (Photo courtesy of the American Society for Microbiology).

Assay Detects Zika in Semen Samples

Researchers have found that an available clinical assay could reliably detect Zika virus from semen samples spiked with low levels of recombinant Zika virus. More...

LAMP Assay Validated for MRSA in Invasive Samples

Staphylococcus aureus is a leading cause of bone and joint infections and one of the most common causative pathogens of bacterial pneumonia in children. An increased risk of mortality from invasive staphylococcal infections has been attributed to methicillin-resistant S. aureus (MRSA). More...

New Test Accurately Detects Latent HIV

The ability of the human immunodeficiency virus (HIV) to lie dormant in a "reservoir" of CD4 cells has been the main obstacle to finding a cure; once a patient starts antiretroviral therapy, it becomes very important to measure the level of viremia, and whether the virus can replicate. More...

Multiplex Immunoassay Diagnoses Toxoplasmosis and Rubella

Primary infections of Toxoplasma and rubella in pregnant women may result in vertical transmission of the pathogens, which can cause congenital disease that significantly affects fetal development. More...

A new conducting polymer was developed for detecting specific interaction of trisaccharide with hemagglutinin in the envelope of the human influenza A virus (H1N1) by electrical manners (Photo courtesy of the Tokyo Medical and Dental University).

Biosensor Technology Enables Rapid Detection of Flu Virus

A research team has developed a voltage-sensor for early detection of influenza virus A (H1N1) that is almost 100 times more sensitive than conventional tests, and can distinguish between human and avian strains. More...

Image: Determining which stain on these paper filters (top row) is from blood (C) rather than coffee (A) or tea (B) is easier with the new, more selective artemisinin-luminol chemiluminescence test for forensic bloodstain detection (bottom row) (Photo courtesy of ACS).

Antimalarial Compound Improves Forensics of Bloodstains

Forensic investigators often use a luminol chemiluminescence test to detect latent bloodstains at crime scenes. Now, researchers have found that combining luminol with the antimalarial drug artemisinin, a natural peroxide, reduces the risk of false positives compared to the traditional method that mainly uses hydrogen peroxide or sodium perborate as coreactants. They also obtained test results using a smartphone, which could provide highly accurate on-scene analyses. More...
