Transcript of Principles of Infection

CHAPTER 5
COSMETOLOGY I

PRINCIPLES OF INFECTION
BACTERIA
MINUTE-ONE CELLED
VEGETABLE MICROORGANISM
FOUND NEARLY EVERYWHERE

ALSO KNOW AS
GERMS OR MICROBES
EXIST ALMOST ANYWHERE
CAN ONLY BE SEEN WITH MICROSCOPE
TWO TYPES OF BACTERIA
NON PATHOGENIC
PATHOGENIC
HELPFULL OR HARMLESS
METABOLIZE FOOD
PROTECT
STIMULATE IMMUNE SYSTEM
IMPROVES
THE
SOIL
DECOMPOSE TRASH
IN YOGURT TO HELP WITH DIGESTION
HARMFUL
DISEASE CAUSING
BAD!!!!!
MICROBACTRIUM
FORTUITM
FURUNCULOSIS
A GERM THAT CAUSES INFECTION FROM IMPROPER CLEANING OF FOOT SPAS
CLASSIFICATION OF PATHOGENIC
BACTERIA
COCCI
BACILLI
SPIRILLA
COCCI
ROUND SHAPE
SINGLY OR IN THE FOLLOWING
GROUP OF 3
Staphylococci
Streptococci
Diplococci
PUS FORMING
GROW IN CLUSTERS
ABSCESSES, PUSTULES, BOILS
STAPHYLOCOCCI
PUS FORMING
CURVED LINES
CAUSES INFECTION
STREP THROAT OR BLOOD POISONING
STREPTOCOCCI
GROW IN PAIRS
CAUSES DISEASES LIKE PNEUMONIA
DIPLOCOCCI
MEANS TWO
SHORT-ROD SHAPED
MOST COMMON
PRODUCE DISEASE
TETANUS, TYPHOID, DIPTHIRIA, TUBERCULOSIS
BACILLI
SPIRAL OR CORK SCREW SHAPED
CAUSES SYPHILIS AND LIME DISEASE
SPIRILLA
POTENTIAL INFECTIOUS MICROORGANISMS
infectious disease is caused by pathogenic (harmful) organisms
may or may not spread from one person to another or from one infected body part to another
Types of Microorganisms
BACTERIA
FUNGI
VIRUSES
PARASITES
BACTERIA
PLANT AND ANIMAL CHARACTERISTICS

BACTERIA
MOVEMENT OF BACTERIA
COCCI- RARELY SHOW SELF MOVEMENT
TRANSMITTED IN THE AIR, DUST, OR IN THE SUBSTANCE
WHICH THEY SETTLE
BACILLI AND SPIRILLA
MOVABLE, USES SLENDER, HAIR LIKE EXTENSIONS KNOWN AS FLAGELLA TO MOVE THROUGH THE LIQUID
growth reproduction
bacteria consist of an outer cell wall called
protoplasm!!

bacteria manufacture their own food, waste products, grow, and reproduce
bacteria has two life cycle stages
ACTIVE
THRIVE IN WARM, DARK, MOIST AND DIRTY PLACES
20-60 MINUTES TO FULLY GROW
DIVIDE INTO TWO NEW CELLS CALLED BINARY FISSION; NEW CELLS ARE CALLED DAUGHTER CELLS
IN-ACTIVE OR SPORE FORMING
BACTERIA SUCH AS ANTHRAX OR TETANUS BACILLI FORM
TOUGH OUTER COVERINGS
CAN WITH STAND LONG PERIODS WITHOUT FOOD
BLOWN ABOUT TO REST ON OTHER SURFACES
CAN LAY DORMANT AND WHEN CONDITIONS ARE RIGHT CAN START THE REGROWTH PROCESS
BACTERIAL INFECTIONS
occur when body tissues are invaded by disease-causing,or pathogenic, bacteria
presences of pus is a sign of infection
Pus
is a fluid product of inflammation and contains white blood cells and the debris of dead cells, tissue elements and
bacteria
Staphylococci
most common human bacteria
can be picked up on door knobs, counter tops by handshaking, or contaminated implements
responsible for:
food poisoning
toxic shock syndrome
MRSA
MRSA
METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS
OCCURS MOST FREQUENT ON PEOPLE WITH LOW IMMUNE SYSTEMS
UNDER GONE MEDICAL PROCEDURES
INITIALLY APPEARS AS A SKIN INFECTION, SUCH AS A PIMPLE, RASH, ADN BOILS THAT CAN BE DIFFICULT TO CURE
WITH OUT PROPER TREATMENT, THE INFECTION CAN BECOME SYSTEMIC AND CAUSE DEATH
LOCAL INFECTION
ONE THAT IS CONFINED TO A SINGLE AREA
PIMPLE, BOIL OR INFECTED CUT
PRESENCE OF PUS IS SIGN OF INFECTION
SYSTEMIC INFECTION OR DISEASE
A DISEASE THAT AFFECTS THE BODY AS A WHOLE, OFTEN DUE TO UNDER-OR OVER-FUNCTIONING INTERNAL GLANDS OR ORGANS

CARRIED TO ALL PARTS OF THE BODY THROUGH BLOOD STREAM OR LYMPHATIC SYSTEM
CONTAGIOUS OR COMMUNICABLE
DISEASE SPREAD FROM ONE PERSON TO ANOTHER BY DIRECT OR INDIRECT CONTACT SUCH AS COUGHING, SNEEZING, UNCLEAN HANDS, UNCLEAN IMPLEMENTS, OPEN SORES, COMMON DRINKING CUPS, COMMON TOWELS
viruses
live by penetrating cells
resistant to antibiotics
prevented by vaccination
common example:
(HPV) often seen in salons is the human papilloma virus, also known as plantar warts

VACCINATIONS ARE NOT AVAILABLE FOR ALL VIRUSES
VIRUSES INCLUDE BUT NOT LIMITED TO:
measles, mumps, chicken pox, small pox, rabies, yellow fever, polio, influenza, and HIV (AIDS)
BLOOD BORNE PATHOGENS
disease-causing microorganisms that are carried through the body in the blood or body fluids
HEPATITIS
DISEASE MARKED BY INFLAMMATION OF THE LIVER AND CAUSED BY A BLOOD BORN VIRUS SIMILAR TO HIV/AIDS IN TRANSMISSION
HEPATITIS A
ILLNESS LAST ABOUT THREE WEEKS
SYMPTOMS ARE SIMILAR TO THE FLU
MAY CAUSE YELLOWING OF SKIN AND EYES IN ADULTS
SPREAD THROUGH CLOSE CONTACT
POOR CLEANLINESS AND PERSONAL HYGIENE
CONTAMINATED FOOD HANDLERS ADN SEXUAL CONTACT

VACCINE IS AVAILABLE
HEPATITIS B
(HVB)
can cause long term hepatitis, cirrhosis, and/or liver cancer
maybe no symptoms or flu like symptoms
Primarily transmitted through sexual contact or blood transfusions or shared infected needles
vaccine is available
HEPATITIS C
(HCV)
PROGRESSES SLOWLY
1/3 WITH THE ILLNESS SHOW SYMPTOMS
FATIGUE AND STOMACH PAIN
TRANSFERRED THROUGH PARENTERAL CONTACT AND SEXUAL ACTIVITY WITH INFECTED PARTNERS

NO VACCINE AVAILABLE
HIV/AIDS
HUMAN IMMUNODEFICIENCY VIRUS- THE VIRUS THAT CAUSES AIDS- ACQUIRED IMMUNODEFICIENCY SYNDROME

AIDS BREAKS DOWN THE BODIES IMMUNE SYMPTOM
PASSED THROUGH THE BLOOD AND BODY FLUIDS
UNPROTECTED SEX
SHARING OF IV NEEDLES WITH INFECTED DRUG USERS
ACCIDENTS WITH NEEDLES IN THE HEALTH-CARE FACILITIES
THROUGH CUTS AND SORES
ACTIVITIES THAT ARE NOT METHODS FOR TRANSMITTING THE DISEASE
HAND HOLDING
HUGGING
KISSING
SHARING FOOD/HOUSEHOLD ITEMS
CAN BE INFECTED FOR MANY YEARS WITHOUT SHOWING SYMPTOMS
THERE ARE NO DOCUMENTED CASES OF THE VIRUS BEING TRANSMITTED BY FOOD HANDLERS, INSECTS, OR CASUAL CONTACT
FUNGUS
PLANT PARASITE THAT INCLUDE MOLDS, MILDEWS, AND YEAST

THEY CAN PRODUCE CONTAGIOUS DISEASE SUCH AS RINGWORM
TINEA BARBAE
KNOWN AS BARBER'S ITCH
AFFECTS BEARDED AREAS SUCH AS BEARD, FACE, NECK OR AROUND SCALP
TINEA CAPITIS
FUNGAL INFECTION OF THE SCALP
TINEA PEDIS
RINGWORM FUNGUS OF THE FOOT
PARASITES

ORGANISMS THAT GROW, FEED, AND SHELTER ON OR IN OTHER LIVING ORGANISMS
INTERNAL PARASITES CAN BE ACQUIRED THROUGH eating OR FISH OR MEAT THAT HAS NOT BEEN PROPERLY COOKED

EXTERNAL PARASITES INCLUDE
TICKS, FLEAS, MITES AND HEAD LICE
PEDICULOSIS CAPITIS IS TECHNICAL TERM FOR LICE
SCABIES IS A ITCH MITE THAT BURROWS IN THE SKIN
COSMETOLOGIST CAN NEVER TREAT OR DIAGNOSIS CONTAGIOUS DISEASES CAUSED BY PARASITES....


THEY MUST BE REFERRED TO THEIR PHYSICIAN
HOW DO PATHOGENS ENTER THE BODY:
BREAK IN SKIN
MOUTH
NOSE
EYES OR EARS
UNPROTECTED SEX
HOW DOES BODY FIGHT INFECTION
THROUGH UNBROKEN SKIN
BODY SECRETIONS SUCH AS PERSPIRATION AND DIGESTIVE JUICES
WHITE BLOOD CELLS
ANITOXINS
IMMUNITY IS THE BODIES ABILITY TO FIGHT OFF INFECTION AND DISEASE AND TO DESTROY BACTERIA THAT ENTER THE BODY
NATURAL IMMUNITY
ACQUIRED IMMUNITY
