Disease causing microbes
Pathogens
Disease caused by pathogens
Infection
Chain of infection
Pathogen Reservoir Portal of exit Method of transmission Portal of entry Susceptible host
Pathogen
Microbe capable of causing a disease
Reservoir
Storehouse for microbes to grow and multiply
Reservoirs for microbes
Bodies of people and animals
Bodies of water
Food
Portal of exit
Microbes exit vary depending on the pathogen and reservoir.
If human or animal the portal can be
The respiratory tract
The genitourinary tract
Breaks the skin
Transmission of pathogen
Direct: pathogen passed thru close physical contact. I.e. touching kissing sex
Or
Breathing infected air
Indirect: pathogens passes by way on contamination I.e. Touching surface or object
Portal of entry
Way of gaining entry to new reservoir.
Potential portals are: respiratory, digestive, genitourinary, eyes and breaks in the skin
Susceptible host
Person capable of becoming infected with a particular pathogen
Persons susceptibility to infection:
Age very young or very old
Poor general health
Presence of medical devices placed in body ie
Urinary catheters.
Health care-associated infection
Nosocomial infection
Nosocomial infection
health care-associated infections
Nosocomial infection. Super bugs
Methicillin-resistant Staphylococcus aureus (MRSA)
Clostridium difficile or C-diff
Vancomycin-resistant enterococcus (VRE)
MRSA
Methicillin-resistant Staphylococcus aureus
Staph infection caused by direct contact
Serious infections of blood, lungs, heart or bone
C-diff
Clostridium difficile
Microbe passes from body feces
Both indirect and direct contact ie. Surfaces or hands
Causes diarrhea and abdominal pain
Spores live for a long time
Must wash hands with soap and water; alcohol
Doesn’t kill spores.
Surface clean with bleach
VEE
Vancomycin-resistant enterococcus
Microbe infects wounds in the
Intestinal tract and the urinary track
Signs of infections
High temperature Red or draining eyes Stuffy nose Coughing Headache Sore throat Flushed face Loss of appetite Nausea Stomach pain Diarrhea Vomiting Cloudy or smelly urine Joint pain Muscle ache Skin rash Sores Redness around wounds or incision Drainage from wound or incision Swelling

Changes in eating or appetite
New onset of loss of bladder or bowel control
More frequent episodes of incontinence
Loss of ability to complete tasks normally able to do
Fatigue or lethargy
Flu-like symptoms
