Bacterial morphotypes in sputum Gram stain (×100, oil immersion field). Gram positive diplococci (lancet-shaped or football-shaped) are suggestive of Streptococcus pneumoniae (A). Cluster of Gram positive cocci are suggestive of Staphylococcus aureus (B). Tiny Gram negative coccobacilli are suggestive of Haemophilus influenzae (C). Gram negative diplococci (kidney bean-shaped) are suggestive of Moraxella catarrhalis (D). Plump Gram negative rods are suggestive of Klebsiella pneumoniae (E). Thin gram negative rods are suggestive of Pseudomonas aeruginosa (F).
