Dark blue rings and circles emerged when the non-specific polysaccharide stain lactophenol cotton blue was added to Gram stained slides. The dark blue staining is attributable to the presence of capsular polysaccharides and bacterial slime associated with clumps of Gram-negative bacteria. Since all bacterial cells are glycosylated and concentrate polysaccharides from the media, the majority of...

The correlation coefficient between the two classifications was computed over the 36 segments for each slide. Correlation shows how well the position of lipid in the two classifications match, even though the absolute values of total lipid areas (i.e., manual and automated) differed. Figure 3 shows that more than 50% of the slides had a correlation coefficient greater than 0.8. Thus, we can say...

I discovered indigo rings and circles in ATCC® 25922TM Escherichia coli cultures when I added the non-specific polysaccharide stain lactophenol cotton blue to Gram stained slides sampled from 96-well plates used to measure quantitative growth kinetics (QGK) in virtual colony count antimicrobial assays. I attribute the dark blue staining to the presence of capsular polysaccharides and bacterial ...

OBJECTIVES The main objective of this study was to assess antral brush cytology as an alternate approach for the diagnosis of H. pylori infection as compared to histopathology. METHODS 75 cases with diagnosis of antral gastritis underwent endoscopic antral biopsy as well as antral brushing cytology was included irrespective of age and sex. Cytological slides were stained with Giemsa stain & b...

background: leishmaniasis is a group of diseases that are created by intracellular parasites of leishmania. cutaneous leishmaniasis is considered as one of the health problems in some provinces of iran. methods: in this study, a total of 178 giemsa-stained slides from confirmed cases of cutaneous leishmaniasis were examined. the slides were prepared from the patients with cutaneous leishmaniasi...
