Changes in Bacterial Load and Serum Cytokine Levels Predict Likelihood of Dying from Sepsis

A testing method for the sensitive and rapid quantification of serum cytokines and bacterial load can be used to predict the likelihood of a patient dying from sepsis or septic shock. More...

Global Spread of the Multi-Resistant Pathogen Stenotrophomonas Maltophilia Revealed

Stenotrophomonas maltophilia strains occur in several natural and human associated ecosystems. The bacterium was long regarded as relatively unproblematic, but is now considered to be one of the most feared hospital pathogens, as it frequently causes infections and is resistant to a number of antibiotics. More...

Cytokine Signatures of Tertian Malaria Infection Profiled During Pregnancy

Malaria caused by Plasmodium vivax is a neglected tropical disease, especially during pregnancy, of worldwide distribution. P. vivax is a protozoal parasite and a human pathogen. This parasite is the most frequent and widely distributed cause of recurring malaria. More...

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...

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...

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...
