| Koch's law | To establish the specificity of a pathogenic microorganism, it must be present in all cases of the disease, inoculations of its pure cultures must produce disease in animals, and from these it must be again obtained and be propagated in pure cultures. Synonym: Koch's law. (05 Mar 2000) |

| Koch, Robert | <person> German bacteriologist and Nobel laureate, 1843-1910. See: Koch's bacillus, Koch's blue bodies, Koch's law, Koch's old tuberculin, Koch's phenomenon, Koch's postulates, Koch-Weeks bacillus. (05 Mar 2000) |

| Koch's bacillus | The Gram-positive bacterium that causes tuberculosis. (09 Oct 1997) |
| Koch's blue bodies | Schizonts of Theileria parva, the causative agent of East Coast fever; found principally within endothelial cells of the spleen and lymph nodes. (05 Mar 2000) |
| Koch's node | sinoatrial node |
| Koch's original tuberculin | <protein> A protein extracted from the tuberculosis bacteriumMycobacterium tuberculosis. It is used in tests to determine if aperson has been exposed to the bacteria and is in danger of coming down with the disease. (09 Oct 1997) |
| Koch's phenomenon | The phenomenon of infection immunity; living tubercle bacilli (Mycobacterium tuberculosis) do not cause reinfection when inoculated into tuberculous guinea pigs (i.e., the animals are "immune" to reinfection) even though the original infections continue to develop and eventually cause death of the animals, rise of temperature and increase of the local lesion, in a tuberculous subject, following an injection of tuberculin.

| Koch's postulates | To establish the specificity of a pathogenic microorganism, it must be present in all cases of the disease, inoculations of its pure cultures must produce disease in animals, and from these it must be again obtained and be propagated in pure cultures. Synonym: Koch's law. (05 Mar 2000) |
| Koch's triangle | A triangular area of the wall of the right atrium of the heart, that marks the situation of the atrioventricular node. (05 Mar 2000) |

| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser. (05 Aug 1998) |
| all or none law | Consistently total response to any effective stimulus. Synonym: all or none law. (05 Mar 2000) |
| American Law Institute formulation | Used in certain jurisdictions to determine criminal responsibility in legal proceedings. See: criminal insanity. (05 Mar 2000) |
| American Law Institute rule | A test of criminal responsibility (1962): "a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law." (05 Mar 2000) |
| Ampere's law | <physics> General equation in electromagnetism relating the magnetic field and the currents generating it. The various forms of the equation can be found in an introductory electromagnetism text. (09 Oct 1997) |
