HERE’S THE GRAM STAIN YOU ORDERED FOR STUDY

Clinical Specimen of lung

A = Gram + diplococcus	B = Gram + coccus	C = Tissue cell	D = Tissue fiber
Can you find other diplococcal forms in this slide? How might a diplococcus look like a single coccus (labeled B in this slide)? When you look at a clinical specimen for bacteria, think small!! Look for the little dots or rods. Then look closer and see if you can determine the primary cell morphology: are they primarily singles, doubles, in chains?
