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 ...

Bacterial species, and even specific strains can be differentiated using a number of molecular techniques such as PCR, quantitative PCR, genome sequencing and mass spectrometry. But even without ...

After more than 130 years, scientists may finally have figured out how a common laboratory method for identifying bacteria works. Invented by Hans Christian Gram in 1884 and thus known as the gram ...

Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...

Your doctor may use an acid-fast bacteria (AFB) stain test to see if you have a lung disease like tuberculosis (TB). In addition to showing tuberculosis, an AFB stain can also show if you have another ...

Chemists have developed a fluorescent probe, BacGo that can detect Gram-positive bacteria precisely and promptly. The research team used bacterial sludge from wastewater for the demonstration ...

Your doctor can order this test to find out if you have tuberculosis (TB) or another type of bacterial infection. TB was very common at one time. However, it’s now rare in the United States. According ...
