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.
Bacteria Slide Set (Large) includes 50 microscope slides:
Rod-shaped bacteria, non-spore-forming, gram-positive: • Corynebacterium diphtheriae, smear from culture • Lactobacillus bulgaricus (Thermobacterium), Yoghurt bacteria (Bulgarian soured milk), from culture • Mycobacterium leprae, causing leprosy, smear or tissue section • Mycobacterium tuberculosis, smear from positive sputum stained after Ziehl-Neelsen
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
Spiral bacteria and spirochaetes: • Borrelia duttoni (Spirochaeta recurrentis), causes Central African relapsing fever, blood smear with organisms • Rhodospirillum rubrum, chromogenic rods, smear • Spirillum volutans, a very large spirillum, smear • Vibrio comma, causing Asiatic cholera, smear
Miscellaneous groups: • Actinomyces alni, sec. of root nodule showing mycorrhiza of alder • Bacteria from cheese, smear or section • Bacteria from human intestine, smear • Bacteria from mouth, Gram positive and negative bacteria can be observed in this slide, ideal for demonstration • Bacteria from sauerkraut, smear • Methanobacterium, forming methane, smear • Sphaerotilus natans, from putrid water, long chains with sheaths • Streptomyces griseus, streptomycin antibiotic, smear
Cytological slides, special staining techniques: • Monotrichous flagella on Vibrio or Pseudomonas, specially stained • Nuclear stain (Bacillus cereus), smear specially stained for nuclear material (DNA) • Peritrichous flagella on Salmonella or Proteus, specially stained • Typical mixed bacteria, including Gram-positive and Gram-negative rods, smear
