Normal Flora Flashcards
Opportunist
Benifit bacteria
-resident flora
E.coli
S.epidermis
Transient flora
S.pneumonia
Carrier
Individual is carrier the source of infection that lead to colonization
A symptomatic
(Not related to normal flora)
In 3 ways of normal flora plays on body
1-exist in immunocompromised individual
2-colonization resistance
3-source of nutritional (vitamin Kand B)
Intistinal microbiota
Plays role in autoimmune disease
Gut microbioata
Affect in the function and mutoration of immune response
Bacteriocins
Antibiotic from bacteria
Bad normal flora what cause?
1-urinary tract infection(e.coli)
2-pretonitis (bacteriod fragilis)
3-endocarditis(streptococcus varidans/s. Mutans)
What is antibiotics repressor the normal flora?
1-calindamycin : instead inhance to growth (clostridiym difficle)lead to colotis
2-neomycin( to sterilize GI surgery)
Main bacteria in throat
Streptococci and staphylococcus
Main viridans streptococcus in mouth
Mutant streptococcus that cause endocarditis
Normal flora in small intestine
1-streptococci
2-lactobacilli
3-candia albicans
Main normal flora in genitourinary tract
Lactobacilli which produce acidic ph lead to inhibition for c.albecansgrowth
Bacteria contaminated urea
1-coliform
2-non hemolytic streptococci
3-corinybacterium
4-s.epidermis
Bacteria found in secretion around urethral area
Mycobacterium smegmatis
Bacteria found in skin around genitourinary tract and cause UTI in women
Staphylococcus saprophyticus
Probiotics
Used normal flora to treatment GI tract
3- main types of probiotics
1-lactobacillus acidophilus
2- bfedobacterium bfedum
3-streptococcus thermophilus
5 benifits of probiotics
1-treatment and prevention diarrhea 2-food allergic 3-treatment from GI inflammation 4-alleviate symptomsof lactose intolerance 5- reduction of respiratory infection
Advantages of normal flora
- stimulation of natural antibody
- competitive with pathogens -nutrition
