Anaerobes

Front 1

Gram + Anaerobes:
1) cocci
2) bacilli

Back 1

1) peptostreptococci
2) Clostridium, Actinomyces, Proprionbacterium

Front 2

Gram - Anaerobes:
1)cocci
2) bacilli

Back 2

1) no important pathogens
2) Bacteroides, Porphyromonas, Prevotella, Fusobacterium
-inhabitants of upper respiratory, GI, and female genital tracts
-occasionally produce infections in these locations (lung abscess, peritonitis, PID)

Front 3

Anaerobic infections

Back 3

-polymicrobial infections that smell really bad
-manifest as abcesses
-puncture wounds (tetanus, gas gangrene/clostridial myonecrosis)
-diffuse infections of lungs, meninges, etc are difficult because anaerobic conditions can't prevail

Front 4

Clostridium

Back 4

Gram + bacillus
-cause of tetanus, botulism, and clostridial myonecrosis
-most common cause of infectious diarrhea of hospital pts (C. difficile)
-produce spores that can survive in aerobic conditions until they are inoculated into an anaerobic environment

Front 5

Actinomyces

Back 5

Gram + bacillus
-occasional normal flora of respiratory and female genital tract
-chronic draining infections with sinus tracts

Front 6

Propionibacterium acnes

Back 6

Gram + bacillus
-causes acne

Front 7

Peptostreptococci

Back 7

Gram + cocci
-normal in upper respiratory tract
-brain abscesses
-polymicrobial lung abscesses that develop following aspiration pneumonia
