Across
- 6. Likely to spread infection
- 8. Capable of being transmitted from one host to another
- 10. The presence of an agent with the ability to produce disease
- 12. The ability of an agent to cause harm or impact the fitness of affected hosts
- 14. Form of transmission between individuals in the population independent of parental relationships
- 15. Interactions between individuals of the same species
- 16. The science of studying the occurrence of disease
- 17. The second step in energy metabolism
- 19. A blood-feeding arthropod involved in indirect transmission of disease
- 21. Of unknown cause
- 25. Stimulus that disturbs an animal’s homeostatic equilibrium
- 26. Host population in which the agent can persist without external sources of infection
- 27. Host population in which the agent can persist for a time but will eventually die out without an external source of infection
- 30. Hosts that can acquire but not transmit the infection
- 31. Objective evidence of disease
- 34. Parasites that must infect a host to survive and reproduce
- 36. An individual that is infected but has no apparent morbidity
Down
- 1. Interactions between individuals of different species
- 2. Randomly determined and difficult to predict
- 3. Disease in animals that occurs in a time or place where it is not expected, or at a rate greater than expected on past experience
- 4. Type of infection in which there are no obvious clinical signs
- 5. Type of mortality that results in additional deaths above those that would have died anyway
- 6. The first step in energy metabolism
- 7. Human-caused or of human origin
- 9. The proportion of animals in a population affected by a disease at a given time
- 11. Type of mortality that results in no more animals dying than would have died anyway
- 13. Type of disease caused by living organisms that cause harm while living in/on host’s body
- 16. Disease in animals that occurs with predictable regularity and rate in a population or in an area
- 18. Type of habitat where mortality is greater than reproduction
- 20. Any impairment that interferes with or modifies the performance of normal functions
- 22. A cause that is immediately responsible for causing the event
- 23. The act of leaving a population or site (by movement, rather than by death)
- 24. Lifetime reproductive success
- 28. How we typically measure cost of disease in animals
- 29. A species (or group of species) capable of permanently maintaining the agent, from which it may occasionally spill over into a species of interest
- 32. Form of mortality where the disease does not kill the animal outright, but increases risk of mortality from other things
- 33. The condition of being impacted by disease
- 35. Ancient form of immunity that requires no previous exposure to an agent
