a small amount of discharge from the infected area will be placed on a slide, stained with a special dye, and examined under a microscope for the presence of the gonococcus bacteria
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.
Gram stain
The counter or secondary stain used in the Gram stain procedure is safranin.
Yogurt contains mostly lactic acid bacteria, which are Gram-positive bacteria. This means they will stain purple under a Gram stain.
In the flagella stain, all cells appear purple due to the basic dyes used to stain the flagella. This uniform coloration helps visualize the flagella structure under the microscope. In contrast, the Gram stain uses a series of dyes to differentiate between Gram-positive (purple) and Gram-negative (pink) cells based on their cell wall composition.
A gram stain cannot detect chlamydia. A gram stain in men that finds gram negative diplococci is considered diagnostic for gonorrhea, but it can't be used in females, and it can't prove chlamydia. A gram stain in men can be used to rule out gonorrhea and possibly diagnose "non-gonococcal urethritis" if a male has symptoms. However, although it may seem that NGU is synonymous with chlamydia, there are other possible causes.
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.
Gram stain
Gram Negative
Protists are often stained using a silver stain, not a Gram stain.
The Gram stain is used for bacteria and not for viruses.
Enterobacter cloacae is a Gram-negative bacterium. It will stain pink or red in a Gram stain procedure.
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
The counter or secondary stain used in the Gram stain procedure is safranin.
Yogurt contains mostly lactic acid bacteria, which are Gram-positive bacteria. This means they will stain purple under a Gram stain.
Lassa fever is a virus. It does not have a gram stain characteristic.
If you are talking about a Gram Stain, then red. E. coli is Gram negative which means that Safranin will stain it red during a gram stain.
