Define infection

When pathogenic microorganisms penetrate the host cell

Define infectious disease

The distruptin of a tissue or organ caused by microbes of their product

Define resident biota

The ambndance of microorganisms found in it in the the human body

What are locations of resident biota

Skin, respiratory tract, lungs, external ear canal, vagina

Define microbial antagonism

The effect of beneficial microbes of normal biota

Describe endospores infections

Caused by biota already present in the body

What can endospores infections cause

Pink eye

What are factors that weaken the host defenses against infections

Age, genetic defects, surgery, chemotherapy, stress

Describe initial colonoziation of the newborn

Fetus are seeded with normal microbiota in the utero

When does exposure occur in this process

During the birthing process

What are ways you can get this

Bottle feeding, breast feeding, hospital staff

Define opportunistic pathogens

Cause disease when the host defenses are compromised

What is the first stage in the process of infection

Portals of entry( infectious agent enter the skin)

Describe stage one of the process of an infection

Microbes enter the tissues by a charastic route through the skin, respiratory tract, or GI tract

Define exogenous

Originally from a source outside the body

What is the second stage of the infection process

Adhesion

Define adhesion

Attachment to the host cell

What is the third stage in the process of infection

Surviving the host defenses

Define phagocytes

White blood cell, enguif and destroy pathogen by means of enzyme and antimicrobial chemical

What is the fourth step in the process of infection

Causing disease

What are the three main ways that microbes cause damage to hosts

Secreting proteins that directly damage host cell, by causing an overreaction by the body defenses, by altering the host cell genome

Define asymptotic

The patient experienced no symptoms

What is step five of the process of infection

Vacating the host portals of exit

Describe step 5

Respiratory and salivery, skin scales, fecal exit, bleeding or removal of blood

What are the four phases of infection

Incubation period, produmal stage, period of invasion, convalescent period

Describe the incubation period

The time from the initial contact with the infectious agent to the appearance of the final symptoms

Epidemiology

The study of frequency of diseases and other health related factors

Describe the prodromal stage

Short period, light symptoms

Describe the period of invasion

Peak activity, the infectious agent multiplies at high levels

What is the name of the fifth stage of infection which only sir infections have

Continuation

Define reservoirs

Primary habitant in the natural world from which a pathogen exist, permanent place to reside

Describe living reservoir carrier

Individual who inconspicuously shelters a pathogen, can spread to others

Do convalescent patient have symptoms

No

Define zoonosis

Infection spread between humans and animals

Describe communicable

Microbe that causes disease can be transmitted from infected host to another host

Non communicable

Cause by weakened immune system

Prevelance is the

total number of cases

Incidence is the

Number of new cases

Mortality is the

Number of death due to cases

Define endemic

Infectious disease that exhibits a relatively steady frequency over a long period of time

Define sporadic

Occasional cases are repeated at irregular latenals

Considered the most common bacterial case of diarrhea in the u.s

Symptoms of campylobacter

Watery diarrhea

What are the symptoms of chorera

Vomiting, muscle cramps, watery feces, severe thirst, sunken eyes

Treatment for chorera

Replacement of water and electrolytes

Describe giardia

A pathogenic flagelled protozoan first observed first observed by Antoine van

Describe entamoeba

Tissue damage the annoeba secrets enzymes that dissolve tissue

Describe taenia solium

The pork tapeworm, around 5 meters long, contains a scolex

How is taenia solium ingested

Undercooked meats
