With Prime Day coming up on July 8-11, now's the time to get one of the best microscopes for students, essential tools to help budding scientists with their studies.

Gram-positive bacteria show blue or purple after Gram-staining in a ... It involves staining an organism with crystal violet or methylene blue dye and then observing the organism under a microscope.

These staining techniques can highlight specific details or differentiate between similar organisms (like Gram staining for bacteria), as not all tissues absorb stains in the same way.

The interpretation of conventional glass Gram stain microscopy slides is both subjective and time consuming. The first step towards Digital Pathology is to convert Gram slides into Whole Slide Images ...

For example, in sputum Gram staining, Gram-positive diplococci and Gram-negative coccobacilli were identified as S. pneumoniae and H. influenzae, respectively. As the type of causal pathogen of ...

AI-based tissue staining can detect amyloid deposits without chemical stains or polarization microscopy. Your friend's email. Your email. I would like to subscribe to Science X Newsletter.

Enhanced stains for gram-positive and gram-negative bacteria. New Gel IIluminator Offers Alternative to UV and LED-based Light. Microscopy & microtechniques Novel nuclear stains for microscopy and ...

Compared with other methods, urine Gram stain moderately predicted gram-negative bacteria but added little value to UTI diagnosis in the ED, raising questions about its clinical utility.

First, gram-negative bacteria have a thin cell wall that is about 1.5 to 10 nanometers across, whereas gram-positive bacteria have a thick cell wall measuring about 20 to 80 nanometers.

From classical methods like Gram staining and dark-field microscopy to advanced techniques like confocal and electron microscopy, each approach offers unique advantages in diagnosing different STIs.

Unlike dark-field microscopy or immunostaining, the sensitivity and specificity of diagnosing syphilis using Gram staining should be low. However, Gram stain may aid in syphilis diagnosis because it ...
