Common examples of these pathogenic agents are Plasmodia and Amoeba

Common diseases associated with these pathogenic agents are jock itch, candidiasis and ringworm

Commonly treated with Albendazole and Pyrantel pamoate

These are the smallest biologic agent

Commonly called as the "Rocky Mountain Fever" caused by a tick which infects the endothelial cells of the blood vessels

It is the disease phase where the interaction between the host, the agent and other factors before the agent contacts with the host.

Disease phase where:
invasion -> incubation -> clinical horizon -> recovery/disability/death.

Also known as the phase of "host-agent interaction"

All are requirements of a host for a successful invasion of the agent, except:

All are manifestation of a host-agent relationship, except:

Reaction of the host when infected:
Natural resistance, acquired immunity, state of good health etc. or can be due to weak or smaller dosage.

Reaction of the host when infected:
The force of agent and host are equal so both are not affected. (Host become a carrier which can easily spread the disease and evade detection)

Reaction of the host when infected:
Very mild that they escape detection. (Host is a carrier state)

Reaction of the host when infected:
The condition of the host can be typical or atypical

All are pathogenic mechanism of an invading BACTERIA, except:

Human's Carrier State:
The patient develops chronic infection and transmit infection for a long period of time - over 1 year 

Human's Carrier State:
The patient recovered from an acute illness may continue to shed the organism

Human's Carrier State:
The patient transmit the infection shortly before they become symptomatic 

Human's Carrier State:
The patient never develop symptoms of the disease 

Human's Carrier State:
Example - Hepatitis A virus

Human's Carrier State:
Example - Chicken pox

Human's Carrier State:
Example - Shigella

Human's Carrier State:
Example - Hepatitis B virus and HIV

Host's portal of entry/exit:
Via buccal cavity and saliva down to the GI route  

Host's portal of entry/exit:
Via expectoration, sneezing and coughing

Host's portal of entry/exit:
Via urine and genital secrtions

Host's portal of entry/exit:
Via percutaneous route by insect bites and needles

Host's portal of entry/exit:
Example - impetigo, syphilis and chickenpox

Host's portal of entry/exit:
Example - rabies virus, HAV

Host's portal of entry/exit:
Example - Leptospirae, STIs

Host's portal of entry/exit:
Example - influenza virus, M. tuberculosis

Host's portal of entry/exit:
Example - rubella, cytomegalovirus, syphilis

Host's portal of entry/exit:
Via placenta while the fetus is developing

General factors of resistance:
Eliminating harmful agent via GI tract

General factors of resistance:
The susceptible host prevents pathogenic organisms from growing. 

A specialized mucus-secreting epithelial membrane that lines the interior surface of the eyeball.

Action of the immune system for delayed hypersensitivity and regulation of antibody production

Action of the immune system where it inactivate specific antigens or organisms and prevent replication in the body

The antibodies are given to the host where it provides immediate protection.

Examples are:
Cachetin, Lymphotoxin & Bacteriocins

Levels of Disease Prevention:
It is applied in the pre-pathogenesis phase

Levels of Disease Prevention:
good habits of health and hygiene

Levels of Disease Prevention:
proper and prompt utilization of available health and medical facilities

Levels of Disease Prevention:
proper sewage disposal

Levels of Disease Prevention:
Increasing the resistance of the possible host 

Levels of Disease Prevention:
Segregation of the reservoir 

Levels of Disease Prevention:
It is applied in the pathogenesis period

Levels of Disease Prevention:
Early detection and prompts treatment of diseases

Levels of Disease Prevention:
Screening programs like Papsmear, primary medical care

Levels of Disease Prevention:
It emphasizes a person’s remaining abilities and attempts to restore the person to as normal a life as possible

Levels of Disease Prevention:
Intensive, periodic follow-up and treatment 

Levels of Disease Prevention:
Disability limitation
