n.) B. Bacteria: Bacterial Shape and Sensitivity to Antibiotics (About 10 m MATERIALS Per student a bacteria type slide compound microscope Per lab room: - Gram-stained bacteria (three demonstration slides) Work alone for this and the rest of these activities. eria exist in three shapess coccus (plural, coci: spherical), bacillus(plural, bacilli rods), and spirillum (plural, spirilla; spirals). PROCEDURE 1. Study a bacteria type slide illustrating these three shapes. Youll need to use the highest magnification available on your compound microscope. In Figure 19-1, draw the bacteria you are observing. In addition to being differentiated by shape, bacteria can be separated according to how they react to a staining procedure called Gram stain, named in honor of a nineteenth-century microbiologist, Hans Gram.
