A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria.

In contrast to direct stains that bind to bacteria directly, a negative stain colors the background of a smear rather than the bacteria. These stains have negatively charged functional groups so they ...

Bacterial vaginosis is confined to an asymptomatic ... As an alternative, Gram-stain-based microbiological diagnosis of BV has been proposed. To perform a Gram stain, vaginal fluid or discharge ...

The presence of endospores in a bacterial culture can be detected by staining with malachite green. Because the endospore coat is so tough, steam is used to enable dye penetration. After washing, only ...

Developed by CarbGeM Inc., a spin-off company of Japanese bioventure NextGeM Inc., the technology uses deep learning to identify bacteria from Gram stains, a common test used to classify bacteria ...

This stain makes it possible to select the protists ... After separating out the individual protists, the researchers then identify the bacteria within or attached to them using genetic sequencing.

Multiple images of fluorescence-stained cells are captured and analyzed automatically for rapid and accurate bacterial cell counts. The QUANTOM™ Total Cell Staining Dye is a green fluorescent ...
