case_images: A Gram-stained smear of pleural fluid showed the presence of occasional pus cells and Gram-positive thin, beaded, branching, filamentous bacteria (Fig. 2a marked with arrow). Modified ZN staining using 1 % sulphuric acid showed acid-fast branching filaments suggestive of Nocardia species (Fig. 2b marked with arrow).
case_images: (a) On Blood agar non-haemolytic, chalky-white dry colonies after 48 h of incubation. (b) On Blood agar slope non-haemolytic, dry chalky-white dry colonies after 48 h of incubation. (c) On Lowenstein-Jensen media showing dry whitish colonies, which on further incubation showed the typical raised, chalky-white dry colonies after 48 h of incubation.

case_images: On blood agar (Fig. 3a, b), the colonies were non-haemolytic dry chalky-white and dry and whitish on Lowenstein-Jensen medium, which on further incubation showed the typical raised, chalky-white dry colonies after 48 h (Fig. 3c).
