What is pathology?
Microorganisms that permanently live in the body.
What is normal microbiota?

What are toxins?

This spread of disease is through contaminated objects
What is indirect contact?

What is etiology?
A relationship where one benefits and the other is unaffected
What is commensalism?
This protein-based toxin is transported through the blood
What are exotoxins?
This refers to the percentage of the populations that has the disease during a given time period
Contaminated water can lead to what type of transmission?
What is waterborne?
The study focuses on how a disease develops
What is pathogenesis?
Microorganisms present temporarily in the body
What is transient microbiota?
A toxin that affects the nervous system
What is a neurotoxin?
Someone is more prone to this due to a weakened immune system
What are secondary infections?
Mosquitoes carry a deadly virus
What is a vector?
The ability of a microorganism to cause disease.
What is virulence?
Most disease-causing bacteria partake in this relationship
What is parasitism?
This toxin is released upon cell death and is primarly found in gram-negative bacteria
What are endotoxins?
What is a pandemic?
This portal of exit can be demonstrated through sneezing
What is the respiratory tract?
When an infection leads to a change in one's state of health
What is a disease?
Organisms that only cause disease when entered into a different part of the body
What are oppurtunistic pathogens?
Can be used to develop vaccines for diptheria and tetanus
What are toxoids?
This disease develops more slow and occurs for a longer period of time (Tuberculosis)
What is chronic?
What are nosocomial infections and what is antibiotic resistance?
