### agent | pathogen:

Bacterial pathogen
* Most bacterial pathogen causes q fevers.
* are the most commonly identified cause of foodborne illnesses
  - causes of outbreaks of food-borne illnesses
* can cause vomiting, diarrhea, stomachache, nausea, headache, and fever.
* cause root decay in some soil conditions.
* survive on clothing, office surfaces for months.

Different pathogen
* Many different pathogens can be foodborne or waterborne, and more are likely to be discovered.
* can solve the same problems in different ways.
* have different durations for incubation
  - modes of transmission

Enteric pathogen
* Most enteric pathogens belong to the gram-negative family Enterobacteriaceae.
* express a variety of virulence factors associated with the production of disease.

### agent | pathogen:

Fungal pathogen
* Most fungal pathogen causes diseases
  - root diseases
* Some fungal pathogen causes infection
  - has potential
  - produces diseases
  - pathogens develop resistance to fungicides after years of repeated applications
* account for a growing proportion of nosocomial infections.
* are responsible for an increasing number of emerging infectious diseases.
* cause flower blight and extensive defoliation.
* reduce soybean yields on millions of acres each year in Minnesota.
* reduces potential for malaria transmission.

Human pathogen
* Most human pathogen causes diseases
  - neurological diseases
* Most human pathogen causes severe diseases
* Some human pathogen causes infection
  - systemic infection
  - threaten infection
* can do damage either directly or indirectly.
* require a variety of vitamins - usually obtained from the host organism.

Important pathogen
* Most important pathogen causes diseases
* Most important pathogen causes severe diseases
* Some important pathogen causes death
  - gastroenteritis
* Some important pathogen causes sudden death
  - oak death

Insect pathogen
* Most insect pathogen causes outbreaks.
* causes disease outbreaks

Opportunistic pathogen
* Most opportunistic pathogen causes diseases.
* Some opportunistic pathogen causes infection
  - serious infection
  - vaginal infection

Plant pathogen
* Many plant pathogens take advantage of wounds in order to penetrate and infect the plant.
* are a part of nature.

Secondary pathogen
* Some secondary pathogen invades damage tissue
* attack the weakened tree.

Several pathogen
* Most several pathogen infects humans.
* Some several pathogen causes infection
  - is transmitted to humans

Significant pathogen
* Most significant pathogen causes diseases.
* causes diarrheal diseases

Viral pathogen
* Many viral pathogens trigger apoptotic events.
* belonging to the group of cyanophages exhibit some degree of host specifity.

Physical agent
* are common environmental pollutants
  - heat, light, ionizing radiation, and filtration
* can occur naturally or can be produced in the workplace.
* offer effective, non-drug methods that can be used to control pain.

Relaxer
* are agents
  - the most damaging of all chemical processes to the hair
* is an agent

Repressor
* bind to silencer sites, controlled by hormones or other signals.
* is an agent
* reduce transcription, inducers increase transcriptions.
* seem to be truly unconscious of their negative emotions.

### agent | retardant:

Flame retardant
* Some flame retardants are minerals or inorganic compounds like antimony trioxide or asbestos
  * A 'flame retardant' chemical substance that makes things harder to burn. Some flame retardants are minerals or inorganic compounds like antimony trioxide or asbestos. Other flame retardants are special types of plastics and polymers. There are several ways flame retardants work. Some absorb heat when they are heated, stopping the thing from igniting. Others stop the heat from the fire from going into the thing. Flame retardants are used in textiles and bedding to prevent them from burning easily
* allows for fireplace use without removing the guard.
