RESUMO

Although the Gram stain is usually used to screen sputum specimens prior to culture, wet mount observation with Nomarski optics has been suggested as a useful alternative. We compared the two methods and found that more specimens were rejected by the Gram stain technique without eliminating any that yielded important clinical information.
