Plasma Virome of Brazilians with Unexplained Symptoms of Infection

 Deep sequencing of nucleic acids in clinical samples now allows the identification of any known infectious agents, resulting in improved diagnostic capabilities. Blood from healthy people with high exposure to viral infections has also been analyzed using metagenomics. More...

SARS-CoV-2 Detected in Multiple Sample Types

 An epidemic of respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in China and has spread to other countries. Real-time reverse transcriptase–polymerase chain reaction (rRT-PCR) of nasopharyngeal swabs typically has been used to confirm the clinical diagnosis. More...

Featuring a short duration time of only 18 minutes, the Elecsys BRAHMS PCT assay can be easily added to any of the automated cobas immunoanalyzer platforms (Photo courtesy of Roche Diagnostics).

Serial Procalcitonin Measurements Utilized in Hospitalized Community-Acquired Pneumonia

 Community-acquired pneumonia (CAP) refers to pneumonia (any of several lung diseases) contracted by a person with little contact with the healthcare system. CAP, the most common type of pneumonia, is a leading cause of illness and death worldwide. Its causes include bacteria, viruses, fungi and parasites. More...

Microbiome Composition Predicts Outcome Among Stem Cell Transplant Patients

 Allogeneic hematopoietic stem cell transplants are common among patients with blood cancers, and while they may cure the disease, such transplants can also lead to complications such as graft-versus-host disease and infections. More...

Gut Bacteria Linked to Pulmonary Artery Hypertension

 Pulmonary arterial hypertension (PAH) is considered a disease of the pulmonary vasculature. Limited progress has been made in preventing or arresting progression of PAH despite extensive efforts. More...

High-Throughput Isothermal HPV Test Validated

 Human papillomavirus (HPV) is a viral infection that is passed between people through skin-to-skin contact. There are over 100 varieties of HPV, more than 40 of which are passed through sexual contact and can affect the genitals, mouth, or throat. More...
