has part realized in has_material_basis_in participates in bacterial infectious disorder Infectious disorder that has some bacterium as part, that exists as a result of a process of formation of disorder initiated by the bacterium. Note that this class does not include all disorders caused by bacterial pathogens. For instance, the disorder that is caused to an organism by c. botulinum toxins is not an infectious disorder. Is there any motivation for also introducing a separate class (as a direct child of 'disorder') with the label 'bacterial disorder' that includes non-infectious disorders caused by bacteria? I am not sure. Take the case of disorder caused by bacteria that do not localize? The disorder does not have bacteria as part. Is the fact that the toxins were produced by bacteria sufficient to make it a bacterial disorder? Concievably, the same disorder could have originated from the same toxins, but injected into the organism in a lab.
