With delicate hues of purple and pink, a lab technique called gram staining has reliably characterized bacteria for more than a century. Yet many scientists are mistaken about why the vivid method ...

Two years ago, a group of infants died at the university hospital and it was found to be Gram-negative bacteria that caused their death. The Gram-negative bacteria turn into pink color and ...

Most bacteria are recalcitrant to traditional cultivation in the laboratory. The soil substrate membrane system provides a simulated environment for the cultivation of previously undescribed soil ...

The Journal of Infectious Diseases, Vol. 43, No. 3 (Sep., 1928), pp. 228-231 (4 pages) A new method of staining flagella includes the treatment of young cultures with acetic acid (q. s. ad 5%); a drop ...

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 ...

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 ...

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 ...

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 ...
