| Viral cultures are being carried out on embryonated eggs in order to isolate the virus and determine its intracerebral pathogenicity index. |
| The known genetic basis for the traits of pathogenicity to non-human species, toxigenicity, and resistance to antibiotics should be provided. |
| In order for such nonpathogenic agents to achieve pathogenicity, they obviously must overcome the defenses of the host. |
| Its genetic code is embedded in a complex DNA structure called the TCP pathogenicity island. |
| Other organisms cultured in these various studies have included a few of highly questionable pathogenicity, such as corynebacteria. |
| Nectrotrophic pathogens commonly produce phytotoxins that are essential for pathogenicity and cause plant cell death. |
