Vaccines that protect people from infection by Streptococcus pneumonia, which kills up to 1 million children every year worldwide, train the immune system to recognize the pathogen's thick sugar ...

Many disease-causing bacteria like Streptococcus pneumoniae (S. pneumoniae) are encased in a sugar layer called the capsular polysaccharide (CPS). This layer is often essential for infections. In a ...

Many dangerous bacterial pathogens have a protective coating that protects them from the immune system. Researchers at Imperial College London have leaned the coat of the bacterium Streptococcus ...

Gram-positive bacteria have thick cell walls. A Gram stain test, which involves a chemical dye, stains the bacterium’s cell wall purple. On the other hand, gram-negative bacteria stain pink instead.

Recently we have done two differential stains, the Gram stain and the Acid Fast stain. Both stains differentiate between bacteria chemically. The two staining techniques of Lab 4 differentiate by ...

Scientists have discovered a new variant of streptococcal bacteria that has contributed to a rise in disease cases in the UK over the last 17 years. Group A streptococcus causes around 600 million ...
