A taxon that is characterised only by its nucleic acid sequence is called phylotypes generally discovered during metagenomic analysis. 13. The period of Incubation is the time that lapses between encounter with a pathogen and the first symptoms. 14. A nosocomial Infection is acquired in a hospital. 15. Living transmitters of an infectious organism from one host to another are called communicable diseases. 16. Epidemiologists define the prevalence rate as a ratio of the # of new cases during a specific time divided by the # of individuals in that population. 17. Virulence may be measured experimentally at the host level by the qualitative and quantitatively, which measures the number of pathogens that kills 50% of an experimental group of hosts within a specified amount of time. 18. The antibiotic susceptibility testing method consists of disks impregnated with specific drugs placed on agar plates inoculated with test microbe. 19. Toxoid vaccines consist of microbes that are either inactivated or attenuated. 20.
