Test method may affect ranking of pathogens (carrier /dry vs suspension; alcohol, chlorine less effective in protein than glut) • Susceptibility of microbes may vary by specific disinfectants (alcohol inactivate mycobacteria but not some viruses) • Numerous factors affect antimicrobial activity: soil load, exposure time, temperature, concentration, surface type, pH, test method, clumping (e.g., virus), biofilms, culture prep, level of microbial contamination, nature of the object, delivery method (e.g., cotton) |
