New Blood Test Can Determine When an Individual Was Exposed to a Pathogenic Microorganism
An international research team has developed a diagnostic blood test – initially for the recurring form of vivax malaria – that can determine when an individual was exposed to a pathogenic microorganism, including the coronavirus that causes COVID-19. More...19 May 2020
Initial Immune Response After Dengue Virus Infection Identified
Dengue virus (DENV) is a member of the clinically-relevant Flavivirus genus together with Zika virus, yellow fever virus and others. With four distinct serotypes, DENV is thought to infect between 280 and 550 million people worldwide every year. More...19 May 2020
Different Methods Compared for Species Identification of Enterococcus
Biochemical test‐based methodologies are still used in some laboratories for the identification of bacterial isolates, mainly because of the need for the performance of drug susceptibility tests. However, these systems are unable to distinguish some species, especially among Gram‐positive bacteria. More...18 May 2020
Immune Responses Evaluated for Tick-Borne Encephalitis
Tick-borne encephalitis (TBE) is an important vector-borne infection of the central nervous system (CNS). The majority of all reported cases of TBE occur in adults. However, TBE should also be included in the differential diagnosis of pediatric CNS infections in endemic areas. More...13 May 2020
Bacterial Blood Infections Tied to Heightened Colon Cancer Risk
Colorectal cancer occurs in the colon or the rectum and it is the third most common type of cancer in the USA. Around 90% of cases occur in people aged 50 years or older. As well as age, risk factors include a family history of colorectal cancer, some genetic syndromes, obesity, and a lack of exercise, a diet low in fruit and vegetables, and inflammatory bowel disease.

Blood Clotting Causes Significant Mortality in COVID-19 Patients
Although the underlying pulmonary pathophysiology remains incompletely understood, severe COVID-19 infection is associated with a marked alveolar inflammatory cell infiltrate, together with a systemic cytokine storm response. More...11 May 2020
CRISPR-Based Microarray System Enables Massive Testing for Viral Pathogens
A novel microfluidic nucleic acid-based diagnostic system is capable of detecting a specific virus from a catalog of more than 160 human pathogens, including the COVID-19 coronavirus, simultaneously in more than 1,000 samples. More...11 May 2020
