Micro-Organisms

Front 1

EYE

1. Description

2. Micro-orgs

Back 1

1. Sparse bc of mechanical action (blinking) & chemical action (tears; have lysozymes); Generally found in conjunctiva (mucus membrane)

2. --Staph (epiderm, aureas);

--Corynebacterium;

--Strept;

--Haemophilus;

--Neisseria

Front 2

SKIN

1. Description

2. Micro-orgs

Back 2

1. Sparse due to innate defenses (dry, sebum, acidic, antimicrobial, peptide secretion, etc.); #/types depend on skin hydration and level of fatty acids (more in axillae, groin & toes bc more moist)

2. --Staph (epiderm);

--Propionibacteria (acne);

--Diphtheroids (non-diphtheria causing Corynebacterium)

Front 3

MOUTH

1. Description

2. Micro-orgs

Back 3

1. Multiple ecosystems

2. --Strept (alpha hemolytic strep i.e. strep mutans & sanguis)... leads to endocarditis & dental plaque/caries

--Facultative Anaerobes (Eikenella corrodens)... bite wound infections

---Anaerobes (spirochetes; porphyromonas gingivalis & proventella intermedia)... gingivitis crevices

--Yeast (candida)

Front 4

ORO/NASOPHARYNX

1. Description

2. Micro-orgs

Back 4

1. Multiple ecosystems

2. --Strept (alpha hemolytic strep)... endocarditis;

--GramNEG cocci (resemble Neisseria meningitides);

--TRANSIENT FLORA:

---Neisseria meningitides... meningitis

---Strept (pyogenes)... pharyngitis

---Staph (aureus)

Front 5

ESOPHAGUS/STOMACH

1. Description

2. Micro-orgs

Back 5

1. Few organisms; most quickly killed by acidity

2. N/A

Front 6

DUODENUM/JEJUNUM

1. Description

2. Micro-orgs

Back 6

2. N/A

Front 7

COLON

1. Description

2. Micro-orgs

Back 7

1. Feces 20% bacteria; up to 10^11 per gram; More than 100 species; Primarily anaerobes

2. --Anaerobes (BACTEROIDES... keep down inflammation; Coliforms... indicate fecal contamination & food;

--GramNEG rods, facultative anaerobes);

--Yeast (candida)

Front 8

VAGINA/ECTOCERVIX

1. Description

2. Micro-orgs

Back 8

1. Flora differs depending on age; Primarily anaerobes; Distal portion normally sterile

2. --Lactobacillus (predominant)... maintain health of vagina by keeping low pH;

--Strept (agalactia)... common & can cause early onset disease, neonatal sepsis & meningitis in babies born to colonized mothers;

--Gardnerella & Mobiluncus... vaginitis

--Staph (aureus)... TSS

-Candida (yeast)... vaginitis

Front 9

Sterile Locations (no bacteria; no NF)

Back 9
