transient microbiota
may be present for days, weeks, or months
normal microbiota
permanently colonize the host
symbiosis
the relationship between normal microbiota and the host
microbes on the skin
staphylococcus, micrococcus, corynebacterium
microbes on eyes
staph. epidermis, s. auerus, corynebacterium, streptococci, micrococcus
microbes in nose and throat
s. aureus, staphylococcus, epidermidis, s. pneumoniae, neisseria
why is there not alot of microbes on the skin?
sweat, oil, keratin, low pH and low moisture
why is there similar microbes between skin and eyes?
conjuctivita is a continuation of the skin to the mucous membrane
microbes in mouth
neissera, streptococcus, staphylococcus, corynebacterium, candida
why is the mouth good at supporting large amounts of microbes?
moisture, warmth and constant presence of food
antimicrobial properties of mouth
chewing, biting, salivary flow dislodges microbes, saliva has antimicrobial properties
microbes of large intestine
e.coli, lactobacillus, enterococcus, candid
- no staph or strep
what does d+ do to normal microbes?
flushes them out
urinary and reproductive system microbes
staph, micrococcus, enterococcus, lactobacillus, candida
vagina environment
acidic, kill microbes, flushes microbes out w urine
where is staphylococcus found
skin, eyes, nose/throat, urinary and reproductive tract
where is streptococci found
eyes, nose/throat, mouth, urinary and reproductive
where is corynebacterium found
skin, eyes, mouth
where is neisseria found
nose/throat, mouth
