Animalia | The kingdom composed of multicellular eukaryotes lacking cell walls |
Antibiotic | An antimicrobial agent, usually produced naturally by a bacterium or fungus |
Aseptic Techniques | Lab techniques used to minimize contamination |
Axial Filament | The structure of motility found in spirochetes; also called endoflagellum |
Bacteria | Domain of prokaryotic organisms, characterized by peptidoglycan cell walls |
Binary Fission | Prokaryotic cell reproduction by division into two daughter cells |
Binomial Nomenclature | The system of having two names (genus and specific epithet) for each organism; also called scientific nomenclature |
Biogenesis | The theory that living cells arise only from preexisting cells |
Cell Theory | All living organisms are composed of cells and arise from preexisting cells |
Enteric | The common name for bacteria in the family Enterobacteriaceae |
Enterotoxin | An exotoxin that causes gastroenteritis, such as produced by Staphylococcus, Vibrio, and Escherichia |
