THE direct observation of the site of Gram stain in cells of micro-organisms could not be attempted before the ultra-thin section technique became available. However, to obtain a suitable section, ...

In a meta-analysis examining respiratory specimen Gram stain for diagnosis of ventilator-associated pneumonia, absence of bacteria on Gram stain had a high negative predictive value, but a positive ...
