Genetic Mutation Identified for TB Vulnerability

About one in five people worldwide are infected with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Of those, only 10%, at most, will show symptoms, because most immune systems have tools to fight the microbe. When these tools are absent or dysfunctional, however, the infection can damage the lungs and other organs, and even cause death. More...

Tools for Meningitis Diagnostics Implemented in Resource-Limited Settings

Meningitis remains a top cause of premature death and loss of disability-adjusted life years in low-income countries. In resource-limited settings, proper laboratory diagnostics are often scarce and knowledge about national and local epidemiology is limited. More...

LAMP Test Rapidly Detects Sexually Transmitted Chlamydia

Chlamydia trachomatis is the leading cause of sexually transmitted diseases (STDs) in females and males in both developed and developing countries, with more than 110 million cases annually. C. trachomatis resists antibiotic treatment and is a cofactor in HIV transmission and human cervical cancer. More...

Dengue Virus IgM Serotyped by ELISA

Dengue virus (DENV) is an arthropod-borne flavivirus that is endemic in tropical and subtropical regions, causing hundreds of millions of infections annually. It is subdivided into four serotypes, DENV-1–4. After infection, patients have lifelong immunity against the homologous serotype but remain susceptible to infections with the others. More...

Gut Microbes Differ Between Two Common Conditions

Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) are two of the most common diseases of the gastrointestinal tract. Unlike IBD, IBS does not cause inflammation, ulcers or other damage to the bowel. More...
