Gram Negative Vs Gram Positive Bacteria Antibiotics
Staining technique: Gram positive organisms have a high amount of material in their cell walls which retain gentian violet (a purple stain) on slides looked at under the microscope. Gram negative organisms have the gentian violet washed out when subjected to acid-alcohol and then they are restained with a red stain which renders them red under the microscope. It is one way of loosely classifying bacteria. ...Read more

Cell shape and growth characteristic are also useful in grouping bacteria until more full speciation information becomes available. The gram stain is fast, reasonably reproducible by trained personnel and the groupings useful 4 rx ...Read more

See below: In the absence of symptoms (urethral discharge, burning, itching), numerous gram positive bacilli usually just represents normal bacterial skin flora and clinically insignificant. Whereas many leukocytes (white blood cells) would suggest some type of infection or inflammation, a few leukocytes is non-specific and may just represent a normal finding. ...Read more
