Flashcards in Lec 1-4 - Actinomyces & Treponema Deck (29):
1

these are part of normal flora, commensals, and can be opportunistic pathogens

actinomyces

2

suppurative means blank lesions

pussY

3

actinomyces cause these lesions

suppurative granulmatous

4

actinomyces can look like yeast because of blank

hyphae

5

early colonizer in oral biofilms

actinomyces viscosus

6

actinomyces viscosus colonizes these surfaces and are associated with this disease

hard surfaces (hydroxyapatite), gingivitis

7

suppurative chronic bacterial infection caused by actinomyces israelii

actinomycosis

8

treatment of actinomycosis is tough because it is part of the normal flora but is treated by these

antibiotic (months long), surgical debridement

9

mycosis is due to blank so actinomycosis is not a mycosis because it is due to bacteria

yeast

10

most prevalent form of actinomycosis

cervicofacial... followed by abdominal and thoracic

11

actinomycosis presents with inflamed indurated mass, can palpate submandibular lymphadenopathy, drainage is milky white or red with yellow flecks which are from blank

sulfur granules

12

central core of actinomycosis is blank

calcified

13

most actinomycosis is due to some sort of blank and starts as a blank abscess

trauma, periapical

14

actinomycosis is almost always wrongly diagnosed because it is the blank

great mimicer of other diseases

15

thoracic actinomycosis is often due to blank and have symptoms like lethargy and fever and weight loss and night sweats (like HIV)

aspiration

16

thoracic actinomycosis can lead to these problems with the cns

brain abscess, meningitis

17

abdominal actinomycosis can be from these

abdominal surgery, gi tract, female gu tract

18

if bone is exposed it is blank

dead

19

bisphosphanates inhibit blank but it makes the bone blank

osteoclasts, dense/avascular

20

3 pathogenic spirochetes (not gram negative even though they look like it)

treponema, borrelia, leptospira

21

spiro that causes sphyilis and necrotizing ulcerative gingiviits

treponema

22

spiro that causes relapsing fever and lyme disease

borrelia

23

spiro that causes leptospirosis

leptospira

24

spiro are strict blank or can be blank and are seen by blank

anaerobes, microaerophiles, darkfield microscopy

25

this causes lyme disease

borrelia burgdorferi

26

this causes syphilis

treponema pallidum

27

this causes yaws and ulcerative granulomas on skin

treponema pallidum pertenue

28

this causes pinta which has depigmentation of skin

treponema carateum

29

primary intraoral site of oral spirochetes

gingival crevice, necrotizing gingivitis (periodontitis)
