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 ...

In a meta-analysis examining respiratory specimen Gram stain for diagnosis of ventilator-associated pneumonia, absence of bacteria on Gram stain had a high negative predictive value, but a positive ...

Similar outcomes in patients with ventilator-associated pneumonia (VAP) suggest that antibiotics selected by Gram staining were noninferior to those based on guidelines and also significantly ...

Sputum Gram stain and culture were once the gold standard of diagnosis in patients with pneumonia but have been discounted in recent years, with published sensitivity estimates ranging as low as 20% ...

THE direct observation of the site of Gram stain in cells of micro-organisms could not be attempted before the ultra-thin section technique became available. However, to obtain a suitable section, ...

Being a cationic dye, crystal violet can be used to stain negatively charged polymers such as DNA 18 and cell walls of bacteria, the latter of which is partially the basis of Gram staining to ...

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 ...

Through the gradual acceptance of an exact method of gram staining two unfortunate by-products have arisen: the waste of countless hours of . . . Select the format you want to export the citation of ...

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 ...
