| A gene from a human pathogen is inserted into a bacterium that infects plants. |
| With antimicrobials our expectation is that the infecting pathogen will be killed, but the myriad normal bacteria are also exposed. |
| Plants require dominant or semidominant resistance gene alleles to specifically recognize pathogen ingress. |
| Malaria, introduced after 1650, became the Chesapeake's most virulent pathogen. |
| Proactive primary prevention presumes that the pathogen can be attenuated or prevented from reaching the individual. |
| If the pathogen causing reinfection is different from the original pathogen, two weeks of treatment are sufficient. |
