Image: The LDBIO test relies on an immunochromatographic lateral-flow assay. This system is designed to detect the presence (or absence) of IgG and IgM antibodies, indicative of Toxoplasma infection (Photo courtesy of the University of Chicago).

POC Blood Test Can Help Prevent Toxoplasmosis

Toxoplasma gondii gains access to human hosts when they eat undercooked contaminated meat or are exposed to material contaminated by feces from an acutely infected cat, which usually goes unrecognized. More...

Strip 1: Y. pestis yreka; 2: Y. mollaretii; 3: Y. frederiksenii; 4: Y. pseudotuberculosis; 5: Y. enterocolitica; 6: Y. intermedia; 7: PCB buffer (Photo courtesy of National Defense Medical Center).

Lateral-Flow Assay Rapidly Detects Plague Bacteria

Plague caused by Yersinia pestis is a known flea-borne disease that can trigger large epizootics among the rodent population. Humans that live in environments close to these rodents can contract the bubonic plague either through direct contact with infected animals or through transmission by infective flea bites. More...

Biomarkers Explored in Patients with Acute Coronary Syndromes

Well-developed coronary collateral arteries are associated with improved survival in patients with coronary artery disease. A key process in forming new blood vessels is attraction to occluded arteries of monocytes with their subsequent activation as macrophages. More...

Biochemical Markers Predict Risk of Incident Diabetes

Low osteocalcin and C-telopeptide of type 1 collagen levels in postmenopausal women are associated with an increased risk for insulin resistance and incident diabetes. More...

Biomarkers Linked to Fatigue in Parkinson’s Disease

Parkinson's disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking. More...

Fifth-Generation Cardiac Troponin Assays Compared

Cardiac troponin I (cTnI) and cardiac troponin T (cTnT) are highly specific biomarkers of myocardial injury. The 99th percentile upper reference limit (URL) of a normal reference population is the recommended threshold which defines an increased cTnI or cTnT plasma concentration indicative for myocardial injury. More...

Immunochromatographic Test Rapidly Diagnoses Parasitic Infection

The rat lungworm Angiostrongylus cantonensis is a food-borne zoonotic parasite that causes eosinophilic meningitis in humans. Suspected cases of A. cantonensis infection can only be confirmed by finding the nematodes in cerebral spinal fluid (CSF) of the patients. More...
