Study an array of single-celled organisms called bacteria in these microscope slide sets. Explore bacteria’s complex relationships with the world—from helpful processing to harmful destruction—in diverse environments like soil, foods, the ocean and the human body. Each slide set includes a full-color brochure with corresponding pictures.

Rod-shaped bacteria, spore-forming (bacilli): • Bacillus anthracis, smear from culture • Bacillus mycoides, large soil organisms growing in chains • Bacillus subtilis, hay bacillus, smear showing bacilli and spores doubly stained • Clostridium botulinum, causing food poisoning, smear • Clostridium perfringens, causing gas gangrene, smear • Clostridium tetani, causing lockjaw, smear
Spherical bacteria, cocci: • Diplococcus pneumoniae, causing croupous pneumonia, smear • Gaffkya tetragena, occurring as tetrads, smear • Neisseria gonorrhoeae, causing gonorrhoea, smear • Neisseria meningitidis (intracellularis), causing epidemic meningitidis, smear from culture • Sarcina lutea, chromogenic rods occurring in packets • Staphylococcus aureus, pus organism, smear from culture • Streptococcus pyogenes, smear from culture showing short chains • Streptococcus lactis, milk souring organism, smear from culture showing short chains
